money serve puts the seven screens in a browser: accounts, transactions, the report with its period axis and sort, the rule builder with its live preview and edit-in-place, the rules list, the transfer builder with its tolerance preview, and the transfers list. Import and retag are buttons in the header. It is one binary: the page is plain HTML, CSS and JavaScript embedded with go:embed, with no framework and no build step. It is a second frontend, not a second implementation. Amounts are formatted on the server, the rule preview is matched by glob.Match there, and the transfer preview runs transfers.Analyze, so the browser only lays out answers and cannot drift from the TUI on what a rule catches or what a pair costs. The server outlives hand edits to rules.toml in a way the TUI does not, so retag and import re-read it first, as a fresh `money retag` or `money import` would, and the overview says when the file on disk no longer matches what the index was derived from. Edits and deletes still go by position, but carry the rule they showed and are refused unless rules.toml still holds exactly that there; a position from a stale tab could otherwise name a different rule. An edit takes the type pattern from the rule on disk, never from the request. There is no authentication, by request. It listens on loopback unless --addr says otherwise, and writes must be sent as JSON so a cross-site form cannot post to it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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
2026-01.csv
2026-02.csv
savings/
account.toml
2026-01.csv
* 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:
--root DIRon the command line$MONEY_ROOT- the
rootkey in$XDG_CONFIG_HOME/money/config.toml, which is~/.config/money/config.tomlunlessXDG_CONFIG_HOMEsays otherwise ~/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.
Usage
money # open the TUI (default)
money serve # the same screens as a web app, on 127.0.0.1:8080
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 i in the TUI) 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
on 4, 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.

There is no key 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 on
4 — which is why that screen shows you what a glob catches before you save.
Report (3)
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.
← and → move along the time axis on the left of the totals, which runs from
the widest window down to the oldest month in the index:
Period Tag Cur Out In Net N
all time groceries EUR 10.00 0.00 -10.00 1
this year TOTAL EUR 10.00 0.00 -10.00
last 12 months
last 3 months
this month
▸ last month
2026-05
2026-04
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. The axis is hidden on a
terminal too narrow for it and the totals both, where the title still names the
period.
s cycles how the rows are arranged, and the marked column 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 filter (a,
enter), the search (/) and the untagged toggle (u) are shared with the
transaction list as before, so opening on last month does not hide the rest of
the index from 2.
money report takes --month instead; there is no command-line equivalent of
the wider windows.
Rule builder (4)
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, 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.

why this rule exists
2 of 7 descriptions match
Only gro was typed in the tag field; ceries is the ghosted completion.
tab / ↑↓ move between the glob, account, tag and note fields, pgup /
pgdn scroll the list, and enter appends the rule to rules.toml and retags
immediately, so the rows it caught disappear from the list. esc goes back.
On a short window the form gives up its spacing and then its hints, so all four
fields stay on screen.
ctrl+s switches the list between by name and by count, most seen first — a
chord rather than a letter, because every printable key belongs to the field you
are typing in. The ↓ in the header 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 complete as you type: the rest of the match is
ghosted in grey after the cursor, and tab (or → at the end of the line)
takes it. When several candidates share the prefix, the hint under the box says
how many, and ctrl+n / ctrl+p cycle through them. Nothing is committed until
you accept it, so a new tag is still just typed out in full. 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.
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
e on the rules screen (5) opens the selected rule in this same form with the
fields filled in, and enter 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, and esc
leaves the rule as it was.
Rules (5)
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 ✗.
money · 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.
e opens the selected rule in the builder to edit it, d deletes it, and p
deletes every rule marked ✗ at once; both deletions ask for a y first. r
recounts against what is currently in the index, which is what you want after an
import has added rows; rules.toml itself is read at startup and whenever you
save a rule from the builder, so an edit made in another window needs a restart.
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 (6)
Same idea as the rule builder, for money moved between your own accounts. Both
sides are named, and the preview on the right 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.

why this transfer exists
1 pairs · 1 unpaired
The account fields complete exactly as the rule builder's do. tab / ↑↓ move
between fields, pgup / pgdn scroll the list, enter appends the definition
to rules.toml and re-pairs immediately, and esc goes back. 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. Six fields need more room than the rule builder's four, so on a short
window this form gives up its spacing, then its hints, then the borders on the
fields you are not editing — every field stays on screen.
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 (7)
Every definition in file order, with what it currently pairs.
money · 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.
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.
d deletes the selected definition and p deletes every ✗ one at once, both
after a y. Definitions marked ⚠ are never pruned — they are doing something,
just not finishing it, and deleting one would hide the problem rather than fix
it. r re-pairs against what is currently in the index.
Web app
money serve puts the TUI's seven screens in a browser — accounts,
transactions, report, rule builder, rules, transfer builder, transfers — with
the same behaviour, because it runs the same code: 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 serve # http://127.0.0.1:8080
money --root /srv/money serve --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.
What differs from the TUI:
- Retag and Import re-read
rules.toml(and Import the account folders) before running, exactly as a freshmoney retag/money importwould — the server outlives hand edits to both. 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, as in
the TUI, but the page also sends the rule it showed you; if
rules.tomlno 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. - Clicking a description in the rule builder's preview fills the glob with
*THAT DESCRIPTION*, as a starting point to narrow down. - Shift-click Import for
import --force.
The keys still work where they do not fight the browser: 1–7 switch
screens, / searches, u toggles untagged, a clears the account filter, i
imports and r retags. On the report ←/→ move the period and s cycles
the sort (or click a column heading); in the rule builder ctrl+s re-sorts the
preview. Inside a form every printable key belongs to the field, as in the TUI.
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:
- 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 bothmatchandtypehas to satisfy both, so both count. - how few
*it uses, the only wildcard that swallows a run of any length:LIDLfixes both ends where*LIDL*does not, so it goes first. (?is not counted either way: it fixes a length, not a character.) - 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, the u view, 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 TUI'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 (3) 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
TOTAL EUR 20.00 0.00 -20.00
(transfers) EUR 500.00 495.00 -5.00 2
⤷ 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 (7) 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. |
traderepublic |
Trade Republic PDF | Handles both the single-line and the stacked layout by measuring column positions. |
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.
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) {

}
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.
