money

A personal finance tracker built around bank statements rather than manual entry.

You keep a data directory with one folder per account, drop statement exports into those folders, and run money import. Transactions are extracted and tagged by glob rules you write.

Layout

~/money/                     # the data root (see "Where the data root lives")
  rules.toml                 # tag rules and transfer definitions, in order
  index.db                   # SQLite index (rebuildable; safe to delete*)
  checking/
    account.toml             # currency + which parser reads this bank's exports

* Nothing lives only in the index: it is derived entirely from the statements plus rules.toml, so deleting it and re-importing gets you exactly what you had. It is a cache and nothing more, which is why it is never migrated — if a new build changes its shape, delete it and run money import again.

Where the data root lives

Checked in order, first one wins:

1. --root DIR on the command line, before or after the command
2. $MONEY_ROOT
3. the root key in $XDG_CONFIG_HOME/money/config.toml, which is ~/.config/money/config.toml unless XDG_CONFIG_HOME says otherwise
4. ~/money

So the usual setup is to write the config file once and never pass a flag again:

# ~/.config/money/config.toml
root = "~/documents/finances"

A leading ~ is expanded and relative paths are made absolute. money config prints the resolved root and which of the four rules chose it.

Install

go install ./cmd/money

Give it the package path, not cmd/money/main.go. Naming the file puts the go tool in file mode: it names the binary after the source file (main) and compiles only the files listed, which breaks the moment the package has two.

That build runs pdftotext from PATH for the PDF parsers, so the machine needs poppler-utils. To deploy one file with nothing to install alongside it, build with pdftotext inside:

scripts/build-bundled.sh           # → dist/money-linux-amd64
scripts/build-bundled.sh arm64     # → dist/money-linux-arm64

It needs podman or docker: pdftotext is compiled in a container from a checksum-pinned poppler release (scripts/pdftotext.Containerfile), as a fully static musl executable with only what text extraction needs, then embedded with go build -tags bundled. The result runs on any Linux of that architecture. The first PDF import writes the embedded copy to ~/.cache/money/ (or $XDG_CACHE_HOME/money/) and runs it from there; money config says which pdftotext is in use. Only Linux on amd64 and arm64 is offered — elsewhere, install poppler-utils.

Building arm64 from an x86 machine runs the container under emulation, so the host needs qemu-user-static and the first build is slow; the executable is then cached under internal/parser/bundled/ and later builds only rebuild money.

Poppler is GPL, so a bundled binary is GPL-licensed as a whole. That matters only if you hand the binary to someone else.

Usage

money                        # the web app on 127.0.0.1:8080 (same as `money serve`)
money serve --addr :8080     # listen on every interface (there is no login)
money import                 # extract new transactions from every statement
money import --force         # re-parse statements even if unchanged
money retag                  # re-apply rules.toml: retag, and re-pair transfers
money ls --untagged          # what neither a rule nor a transfer has claimed
money ls --untagged --uniq   # the same, one row per distinct description
money ls --wide              # also show type and reported balance
money ls --account checking --month 2026-01
money report --month 2026-01 # spending by tag
money report --sort count    # ordered by number of transactions, not amount
money accounts               # balances
money parsers                # available statement parsers
money config                 # which data root is in use, and why

An account folder appears in the app only once its statements have been imported — creating an account.toml is not enough on its own. Run money import (or press Import in the web app) after adding one.

--uniq turns ls into a list of patterns still to write rather than a list of rows to read: one line per distinct description, since fifty visits to the same shop are one glob, not fifty lines. Descriptions print exactly as a glob sees them — upper-cased with whitespace collapsed — so two statements that worded the same payee differently collapse into the one row they deserve, and a pattern written from the list matches what the list showed you.

$ money ls --untagged --uniq
DESCRIPTION
INTEREST PAID
KAUFLAND 4412 SOFIA
LIDL SOFIA 4412

3 distinct descriptions

The account is not part of what makes a row distinct. A rule matches on the description and only optionally narrows to an account, so one payee seen on two accounts is still one pattern to write — and it is one row in the rule builder, which groups the same way. Pass --account to scope the listing instead.

It composes with the other filters (--account, --month, --search), and --limit caps the rows printed, saying how many it held back. It cannot be combined with --wide, whose columns all belong to a single transaction.

The web app

money serve, which is also what money runs with no command, puts eight screens in a browser: accounts, transactions, report, rule builder, rules, transfer builder, transfers and tags. It runs the same code as the CLI: amounts are formatted, globs matched and transfers paired on the server, and the page only shows the answers. It is one binary with the page built in; nothing else to deploy.

money                            # http://127.0.0.1:8080
money serve --root /srv/money --addr 0.0.0.0:8080

There is no authentication. Anyone who can reach the port can read every transaction, rewrite rules.toml and start an import, which is why it listens on loopback unless --addr says otherwise. To use it from elsewhere, put it behind a reverse proxy that does the logging in, or reach it over SSH / a VPN. Requests that change anything must be sent as JSON, so another website open in the same browser cannot post a form to it.

The server outlives hand edits to rules.toml, so it treats the file the way a fresh command would:

• Retag and Import re-read rules.toml (and Import the account folders) before running, exactly as money retag / money import would. Until then a banner says the file on disk no longer matches what the index was derived from.
• Edits and deletes check the file first. They go by rule position, and the page also sends the rule it showed you; if rules.toml no longer holds that rule there (another tab, a hand edit) the change is refused and you are asked to reload, rather than editing whichever rule moved into its place.

Re-read all is import --force: every statement is parsed again, including the ones an Import skips because they have not changed. Use it after updating money, when a parser has learned to read something it used to get wrong; rows already in the index are recognised and not duplicated.

Statements

The Accounts screen also lists every statement file in every account folder, with what the index made of it:

Status	Meaning
✓ imported	read, and unchanged since
⚠ changed	the file differs from what was imported; Import re-reads it
• not imported	new since the last import — or an import tried and failed, in which case the error is in the import report
✗ gone from disk	imported once, then removed; its transactions stay in the index only until it is rebuilt

Transactions reads like 3 rows · 0 new: how many transactions the file holds, then how many of them it was the first to bring in. Statements that overlap share rows, and a shared row is stored once, under whichever file was imported first — so a later statement covering the same days shows fewer new rows than it holds, down to 0 new when an earlier one already had them all. That is deduplication working, not a file that failed to parse.

Click a file name to open it. PDFs and CSVs open in the browser; anything else downloads. Only files import would read are listed or served — not account.toml, dotfiles, or anything outside an account's include patterns.

Delete removes a statement from disk for good — there is no copy kept and no undo, so keep the bank's original if you might want it back. Its transactions leave the index, and transfers that used them lose their pairing: the other leg shows as unpaired, which is the truth once one side is gone. Deleting does not import. A row that an overlapping statement also contains goes too, for now: the account's other statements are marked changed, and the next Import re-reads them and puts it back. For a file already gone from disk the button says Forget and only clears the index.

Adding statements from the browser

The Accounts screen has an Add statements panel: pick the account, drop files on it (or click to choose them) and press Upload. The files are saved into that account's folder, exactly where you would have copied them by hand — the folder stays the source of truth, so deleting index.db and re-importing still gets everything back. Uploading does not import: the files wait on the statements list as not imported until you press Import, so you can put a batch together and look it over first.

An upload never replaces a statement. A file whose name is already in the folder is skipped if its contents are identical and refused if they differ; rename it or remove the old one first. Names import would not read back — dotfiles, account.toml, anything outside an account's include patterns — are refused too, and a batch with one bad file writes none of them. The folder itself must already exist with an account.toml: an upload adds statements to an account, it does not create one.

Some banks name their downloads unhelpfully, so a parser may name the statement instead — lowercase throughout, extension included — and the status line says what each file became. An NLB izpisek is saved as izpisek_YYYY-MM-DD.pdf after the Datum izpiska in its header, and a Trade Republic statement, which downloads as document-N.pdf, as traderepublic_YYYY_MM_DD_YYYY_MM_DD.pdf after the period on its first page (DATE 01 May 2025 - 31 Jul 2026). Either way the folder sorts by date. Downloading the same statement twice then lands on the same name and is recognised as already there; a different statement with the same name (a reissue) is numbered _2, _3 rather than refused. A statement with no date it can find keeps its own name. Only uploads are named — files already in a folder are never renamed, since the index records them by path.

Navigating

Every screen is a link in the bar along the top, and every action is a button or a click; there are no keyboard shortcuts. Clicking an account on the Accounts screen filters the transaction list to it.

There is no control that tags a transaction. Tags come from rules.toml and nowhere else, so tagging what you are looking at means writing a rule for it in the rule builder — which is why it shows you what a glob catches before you save.

Report

The report opens on last month, not on everything you have ever imported: an all-time total is the one number a spending report is least often asked for, and the month that has just ended is the last one your statements can be complete for. If you have not downloaded that month yet, the screen says the period is empty rather than quietly showing you a different one.

The time axis beside the totals runs from the widest window down to the oldest month in the index — all time, this year, last 12 months, last 3 months, this month, last month, then one entry per month. Click one to report on it.

The three rolling windows run to the end of this month rather than to the last complete one — you ask for "last 3 months" to see what is happening now, and leaving out the days since the 1st would answer a different question. Each month below last month is a month the index actually holds; months that a named window above already covers are not repeated.

Click a column heading to change how the rows are arranged; the marked heading says which one they are arranged by: Out ▾ largest spend first (the default question a spending report answers), then In ▾, Net ▾ lowest first so the biggest losses lead, N ▾ most transactions first, and Tag ▴ A→Z. money report takes the same choice as --sort out|in|net|count|tag.

Currency is always the outer grouping and no sort changes that — there are no exchange rates here, so two currencies interleaved by amount would invite a comparison between numbers that cannot be compared. Rows that tie fall back to the tag, so they keep a fixed position rather than shuffling between reloads. The sort rearranges rows; it never changes which rows there are.

The period narrows the report and only the report. The account, the search and the untagged toggle are shared with the transaction list, so opening on last month does not hide the rest of the index from the transaction list.

money report takes --month instead; there is no command-line equivalent of the wider windows.

Rule builder

Writing rules by hand means guessing what a glob will catch. This screen shows the answer as you type: the form is on the left — glob, account, tag, note — and on the right the still-untagged descriptions the glob currently matches, marked ▸, grouped by description, under a running "n of m descriptions match" count.

The list narrows as you type, so what is on screen is what the rule would claim — nothing else is left there to read past. The count keeps the context the rows no longer can: m is everything still in view, so 2 of 7 says the glob picked two descriptions out of seven, and 0 of 7 says the glob is wrong. With the glob still empty there is nothing to filter by, and the list is every untagged description in the data — which is the other question this screen answers, and where you go looking for the next thing to write a rule for. Clicking a description fills the glob with *THAT DESCRIPTION*, as a starting point to narrow down.

enter (or Save rule) appends the rule to rules.toml and retags immediately, so the rows it caught disappear from the list. The account stays filled in, since the next rule is usually for the same one.

Clicking the column headings switches the list between by name and by count, most seen first; the ↓ says which column the order is read from. The two answer different questions: by name finds the payee you are looking at, by count finds the rule worth writing next, since one pattern claiming forty rows is worth more than the first of forty claiming one. Ties keep the alphabetical order, so the list does not reshuffle under you, and the choice lasts until you change it.

The account and tag fields offer completions as you type. Accounts come from the folders on disk and the index; tags from every tag in use plus any named in rules.toml, so a tag is completable from the moment a rule mentions it — which is what stops groceries acquiring a grocery twin. A new tag is just typed out in full.

Leaving the account blank applies the rule everywhere; filling it in also narrows the preview to that account. The preview lists only transactions no existing rule has already tagged, so it answers "what is still waiting for a rule" rather than "what would this rule win". Those differ when the new rule is narrower than an existing one: a *LIDL SOFIA* written while *LIDL* is already tagging those rows previews as nothing and still takes them on save, because the more specific rule wins. Legs of a matched transfer are left out too: they are already accounted for by the definition that paired them, and the report leaves them out anyway.

Editing a rule

Edit on the rules screen opens the rule in this same form with the fields filled in, and saving rewrites that rule where it sits instead of appending a new one. It keeps its position, since position still breaks ties between equally specific rules; rules.toml is edited textually, so the comments and formatting around it survive, exactly as when deleting.

An edit is judged against different rows to a new rule. What the rule already claims is tagged, so none of it would be in an untagged preview and a rule that works perfectly would preview as nothing; those rows are put back, and any the new glob stops catching stays on screen marked −, under a "n no longer claimed" line, rather than quietly disappearing the way an ordinary non-match does. Narrowing *LIDL* to *LIDL SOFIA* therefore shows you the Varna branch you are about to hand back to whatever rule catches it next.

The form has no type field, so a rule that sets one carries it through unchanged rather than losing it; it is shown under the glob as + type:… · kept. Saving lands back on the rules screen with the new counts; Cancel, or leaving the screen leaves the rule as it was.

Rules

Every rule in file order — the order they are written in, not the order they are tried in — with the number of transactions it actually claims. Rules that claim none are marked ✗.

Rules · 5 rules · 2 match nothing

#      Pattern                Account     Tag         Txns  Note
1      *LIDL SOFIA*           (all)       groceries    3     the weekly shop
2   ✗  *LIDL*                 (all)       shadowed     0
3   ✗  *OLD BANK NAME*        (all)       dead         0     closed in 2025
4      *ZARA*                 (all)       clothes      1
5      *КАУФЛАНД*             checking    groceries    1     4412 is the branch

The count is how many transactions the rule wins, not how many its glob could match. Rule 2 above matches LIDL SOFIA 4412 perfectly well, but rule 1 spells out more of it and so claims it first; with nothing else here that says LIDL, rule 2 is dead weight — which is the point of the screen. A rule can therefore reach zero either by matching nothing or by being shadowed, and both are worth deleting. Note that shadowing has nothing to do with the numbering: rule 2 would be just as dead written above rule 1, because precedence is decided by how specific a rule is and not by where it sits.

Edit opens a rule in the builder, Delete deletes it, and Prune unused deletes every rule marked ✗ at once; both deletions ask first. Refresh counts recounts against what is currently in the index. Editing and deleting both work on rules.toml textually, so your comments, ordering and formatting survive. A comment sitting directly above a deleted rule goes with it, while one separated by a blank line is treated as a section heading and left alone; an edited rule keeps its comments, since they say why it is there and changing its glob rarely changes that.

Transfer builder

Same idea as the rule builder, for money moved between your own accounts. The form names both sides — from account, from desc, to account, to desc — plus an optional tolerance and note, and the preview beside it shows what the pair would be: ▸ for a movement it matches end to end, ⚠ for a leg it catches on one side and cannot pair with anything on the other.

    Date        Amount   Movement            Description
⚠  2026-04-01   500.00  checking → ?        TRANSFER TO SAVINGS
▸  2026-03-01   500.00  checking → savings  TRANSFER TO SAVINGS

1 pairs · 1 unpaired

The account fields complete exactly as the rule builder's do. enter (or Save transfer) appends the definition to rules.toml and re-pairs immediately. Saving keeps both account names in place and clears the two globs, since the next transfer you write is usually the same route in the other direction. The tolerance is cleared with them: carried over silently it would loosen a route that never asked for one.

Tolerance % is the one field worth previewing before you save. Type a percentage and the pairs it buys appear immediately, showing both amounts — 500.00 → 495.00 — with what they cost summarised beside the counts:

1 pairs · 0 unpaired · 5.00 in fees

A half-written definition previews too: fill in one side and its legs show up as unpaired, which is the quickest way to see that a glob is wrong before you have written the other half.

Transfers

Every definition in file order, with what it currently pairs.

Transfers · 4 definitions · 1 leg(s) unpaired

#      From                       To                        Pairs  Unpaired  Tol    Note
1   ⚠  checking *TO SAVINGS*      savings *FROM CHECKING*    11     1                monthly saving
2      checking *TO BROKER*       traderepublic *FROM NLB*    4     0
3      checking *WIRE TO SAVINGS* savings *WIRE FROM CHECK*   2     0        1.5%   the bank keeps a fee
4   ✗  checking *TO OLD BANK*     savings *FROM OLD BANK*     0     0               closed in 2025

The two counts mean different things, which is the point of the screen. ⚠ is a definition catching legs it cannot complete: a wrong glob on the other side, a statement not imported yet, or a movement that genuinely went missing. ✗ is a definition matching nothing at all, which is just dead weight.

Click a ⚠ row to see the legs behind it, newest first. Each one says which side is missing and what that side would have had to look like:

Date        Amount   Movement       Missing        Would pair with
2026-04-01  500.00   checking → ?   arriving leg   +500.00 in savings matching *FROM CHECKING*,
                                                   dated 2026-03-27 to 2026-04-06

That is the search to run on the other statement. If it is not there, the statement probably is not imported yet — when nothing at all from that account is, the line says so. If something close is there, the difference tells you which condition failed: a date outside the window, an amount off by a fee (see When the bank takes a fee), or a description the glob does not match. Across currencies the line says any amount, since only the dates are checked there.

Tol is the definition's tolerance_pct, and it qualifies the counts beside it: row 3's two pairs were matched on slack rather than on the amount agreeing. It is blank for every definition that requires the exact amount — which is the default, so an empty column means nothing here is pairing on a mismatch.

Delete deletes a definition and Prune unmatched deletes every ✗ one at once, both after asking. Definitions marked ⚠ are never pruned — they are doing something, just not finishing it, and deleting one would hide the problem rather than fix it. Refresh pairing re-reads what is currently in the index.

Tags

Every distinct tag, A→Z: the ones your transactions carry and any rules.toml names, with how many transactions carry each and the rules that write it.

Tags · 2 tags

Tag         Txns  Rules
clothes        0  #4 *ZARA* (0)
groceries      2  #1 *LIDL* (0)   #2 *KAUFLAND* (1)   #3 *LIDL SOFIA* (1)

Rules are numbered by their position in rules.toml, as on the rules screen, and the count after each is how many transactions it wins — so a tag's rules add up to its transactions, and a rule at (0) is matching nothing or being beaten by a more specific one. It is the place to spot near-duplicate tags (grocery beside groceries) and tags that several rules feed. A tag no rule names any more — rules.toml was edited since the last retag — says so; the next Retag clears it. The transfer label is not a tag and never appears here.

rules.toml

The most specific rule wins, so *NIKOLA* claims what it names even with a broad *NIK* sitting above it, and a catch-all can be written anywhere without swallowing the file. Patterns are globs (* and ?) matched case-insensitively, with whitespace collapsed.

Specificity is measured on what a rule spells out, in this order:

1. how many literal characters its patterns pin down — *LIDL SOFIA* (10) beats *LIDL* (4), and a bare * (0) is tried last of all. A rule setting both match and type has to satisfy both, so both count.
2. how few * it uses, the only wildcard that swallows a run of any length: LIDL fixes both ends where *LIDL* does not, so it goes first. (? is not counted either way: it fixes a length, not a character.)
3. whether it names an account, which is a narrowing the unscoped rule with the same patterns does not have.

Rules that tie on all three fall back to file order, and the earlier one wins — which is what keeps appending a rule from disturbing one already written.

A rule matches on match (the description) and type (the bank's own classification). Setting both is an "and": both must match.

note is free text for you, never for the matcher: why the rule is there, or what the unrecognisable payee behind the glob actually is. It shows in the last column of the rules screen. Ordinary # comments still work and are preserved on delete; a note differs in that it survives a round trip through the tool, so the rule builder can write one and the rules screen can show it.

[[rule]]
tag   = "groceries"
match = "*LIDL*"

[[rule]]
tag   = "salary"
match = "*ACME PAYROLL*"
note  = "paid on the 4th; the December one lands early"

# A rule can be limited to one account, and can require several patterns.
[[rule]]
account = "checking"
tag     = "rent"
match   = "*STANDING ORDER 4471*"

[[rule]]
type  = "CARD_PAYMENT"
match = "*LIDL*"
tag   = "groceries"

Every tag comes from this file, so a tag is never something you have to keep safe: money retag recomputes all of them from the current rules and is safe to run whenever you change it. A transaction no rule matches simply stays untagged, and shows up under money ls --untagged, Untagged only, and (untagged) in the report — unless it is one leg of a matched transfer, which is already spoken for and is left out of all three.

Transfers

Money moved between your own accounts is one movement the statements show twice: an outflow leaving one account and an inflow arriving in another. A [[transfer]] block names both legs, in the same file and with the same globs as everything else.

[[transfer]]
from_account = "checking"
from_desc    = "*TO SAVINGS*"
to_account   = "savings"
to_desc      = "*FROM CHECKING*"
note         = "monthly saving, usually lands the next working day"

# Such movements are often only identifiable by the other side's account
# number, whatever the rest of the description happens to say. Every bank
# parser keeps that number in the description, so an ordinary glob finds it.
[[transfer]]
from_account = "checking"
from_desc    = "*SI56*"
to_account   = "traderepublic"
to_desc      = "*FROM NLB*"

All four _account / _desc keys are required; note and tolerance_pct are optional, and note, as on a rule, never takes part in matching. from_desc is matched against outflows on from_account and to_desc against inflows on to_account, so a definition written backwards pairs nothing.

Two legs are the same movement when they match one definition and are dated no more than 5 days apart. Within one currency they must also be the exact opposite amount, because a movement that arrives short is not obviously the same movement leaving.

When the bank takes a fee

Some routes charge, and then the two statements really do disagree: 500.00 leaves and 495.00 arrives. tolerance_pct says how far short (or over) the arriving leg may be, as a percentage of the leg that left:

[[transfer]]
from_account  = "checking"
from_desc     = "*WIRE TO SAVINGS*"
to_account    = "savings"
to_desc       = "*WIRE FROM CHECKING*"
tolerance_pct = 1.5
note          = "the bank keeps a wire fee"

It belongs to that one definition and loosens nothing else — every other route still needs the exact amount. It defaults to 0, which is what every definition written without the key means, and it must stay under 100: at 100% any amount would pair with any other and the dates would be deciding alone. Keep it as tight as the fee actually requires. Every percent of slack is also a percent more chance of pairing two unrelated movements that happen to fall in the same five days, and where two candidates are the same number of days away the nearer amount wins.

The difference is not forgiven, it is reported. A pair leaves the report entirely, so a fee hidden inside one would be spending that appears nowhere at all. money report names it on the excluded line and the web app's report gives it its own row (see below). Across currencies there is no fee to compute — the two numbers are in different units — so a tolerance there means nothing and is ignored.

Across currencies the amount is not checked at all. An exchange between two of your own accounts — the same money in EUR and in BGN — has two unrelated numbers, and the tool holds no exchange rates, so the dates carry the pairing on their own and the nearest one wins. That is a weaker rule than the same-currency one, deliberately: use the same route twice inside one window and it will pair the wrong two legs. The transfer builder shows both amounts for such a pair (500.00 → 977.90), which is the only place the rate the bank actually used appears.

Definitions are evaluated in file order and each transaction belongs to at most one transfer, so — exactly as with rules — the first definition to claim a leg keeps it.

A matched pair leaves the report entirely. Both legs go together, so a report over everything is unchanged in total by money you shuffled between your own accounts, and money report says what it held out, per currency and per direction — an exchange puts its two legs in different currencies, so each side reports only the leg it saw:

transfers excluded: 4 legs in EUR, 2000.00 out, 1500.00 in
transfers excluded: 1 legs in BGN, 0.00 out, 977.90 in

Where a tolerance_pct definition let a fee through, the line says so too, and that is the number your spending is short by:

transfers excluded: 2 legs in EUR, 500.00 out, 495.00 in, 5.00 in fees

The report screen shows the same thing under its TOTAL, the fee on its own row (for whichever period it is on):

TAG          CUR  OUT     IN      NET      N
groceries    EUR   20.00    0.00   -20.00  1

  ⤷ fees     EUR    5.00            -5.00  1

The fee is counted only for pairs whose legs are both in the report you are looking at, for the same reason the line counts legs and not transfers: filter to one account or one month and you usually have one side of a movement, and half a pair cannot say what the other half received.

A paired leg shows as (transfer) in the tag column of the transaction list and of money ls, so it reads as accounted for rather than as a blank waiting for a rule. That label is display only — nothing writes it to the index, and it is never offered as a tag to complete against. A rule tag wins where there is one, since that is your own word for it.

An unpaired leg is not a transfer and still counts, tagged like anything else. That is deliberate: money that left an account and cannot be shown to have arrived is exactly what you want to see, not something to quietly drop. money import and money retag report unpaired legs on stderr, and the transfers screen shows which definition they belong to.

The pairing is derived state, like the tags: it lives in the index, is recomputed wholesale by money retag and after every import, and disappears with the definition that made it.

account.toml

Every account folder needs one. currency and parser are required.

name     = "Main Checking"
currency = "EUR"
parser   = "nlb"
# minor_digits = 2       # decimal places for this currency
# include = ["*.csv"]    # only treat matching files as statements

Parsers

Three are built in, ported from the original Python extractors. A statement layout is described in Go rather than in a table of column indexes, so there is nothing else to configure — parser names one of these and that is all.

parser	Statement	Notes
nlb	NLB izpisek PDF	Wrapped descriptions are folded in from continuation lines, and the IBAN column is appended to the description. Uploads are saved as izpisek_YYYY-MM-DD.pdf after the statement date.
traderepublic	Trade Republic PDF	Handles both the single-line and the stacked layout by measuring column positions. Uploads are saved as traderepublic_YYYY_MM_DD_YYYY_MM_DD.pdf after the statement period.
revolut	account-statement*.csv	Skips non-COMPLETED rows, folds the fee into the amount.

name     = "Trade Republic"
currency = "EUR"
parser   = "traderepublic"

The two PDF parsers shell out to pdftotext -layout (poppler-utils), exactly as the Python versions did; its layout reconstruction is what makes the column-based parsing work. A build made with scripts/build-bundled.sh carries its own copy instead (see Install).

Amount parsing is shared and deliberately tolerant: 1.234,56, -45.20, 45,20-, (45.20) and 45.20 EUR all work, whichever parser reads them.

Revolut and multiple currencies. One export can hold several currencies, but an account here has exactly one. Rows in other currencies are skipped and reported at import. To keep them, give that currency its own account folder with its own currency and minor_digits (JPY wants minor_digits = 0) and put a copy or symlink of the export in it.

Adding a parser

A new bank means a new parser. Drop it in internal/parser and register it — no other package changes:

func init() {
	parser.Register("bankx", func(acc *config.Account) (parser.Parser, error) {
		return &bankXParser{digits: acc.Digits()}, nil
	})
}

func (p *bankXParser) Parse(path string, acc *config.Account) ([]parser.RawTxn, error) {
	// ... return date (YYYY-MM-DD), description, and signed minor units
}

It becomes usable by setting parser = "bankx" in an account.toml. Use parser.ParseAmount for the decimal handling rather than rolling your own.

Balance checks

Statements that report a running balance are verified on import: each balance must equal the previous one plus the transaction amount, the same check all three original scripts made. A break means a row was missed or misparsed, and is reported as a warning without stopping the import.

Deduplication

Each transaction gets a fingerprint from its date, amount, normalised description, and its ordinal among identical lines in the same statement. So two identical purchases on one day are both kept, while re-importing an overlapping statement adds nothing. Unchanged files are skipped by checksum before parsing.
