Double-entry books for Singapore companies
Invoices, bills, the bank, GST and a real general ledger — where a posted entry is corrected by reversal rather than edited, and a closed year is closed. The rules are in the database, not in the form.

The same refusal comes back from the database itself, so it holds for anything that skips this screen.
1000What this is
aXios Books is double-entry accounting for Singapore companies: invoices, bills, the bank, GST, and statements that tie to the ledger they came from. It does the bookkeeping. It does not pretend to do the thinking.
Every transaction is a journal with debits equal to credits — checked by the database, not by the form. An invoice, a bill, a bank match and a depreciation run all post through the same code, so there is one ledger and no side-tables pretending to be one.
A posted entry is never rewritten. A correction is an equal and opposite entry, and both stay in the books. An entry you showed an auditor in March is still exactly that entry in November.
Who did what, when, and what changed — appended only. The table refuses updates and deletes at the database level, so the record of an awkward month is not something anybody can quietly improve.
Closing a year posts the journal that moves the result into retained earnings, and then locks every date in it. Nothing can be added, changed or removed in a closed year — not an invoice, not a bank match — until somebody reopens it, which is itself recorded with a reason.
Those four are not descriptions of good intentions. They are constraints and triggers in Postgres, which is why they hold even for somebody who bypasses the screens entirely.

Nothing here is a roadmap item. Every line below is a screen you can open on the free plan today.
3000A month in the books
No part of this runs while you are asleep. It is bookkeeping, done in a place that refuses to let you do it wrongly.
An invoice or a bill posts its own journal — receivable or payable, income or cost, and the GST to the right control account. A credit note corrects one without pretending it never happened, in either direction: the ones you issue and the ones a supplier sends you.
A bill over the approval limit needs somebody who can approve it.
A CSV from the bank. The preview shows every row as it was read, before anything is written, because nobody re-reads four hundred lines afterwards. If the headings are unusual, you say which column is which.
Importing changes nothing in your books. It records what the bank says.
Lines that agree exactly with something already in the books are offered with the reason shown, so you can check it rather than trust it. For the ones with no document behind them — the charge, the subscription — write a rule once and it fills in the answer every month after.
A rule fills in the answer. It never posts on its own.
The reconciliation states the difference between the bank and the books and what explains it. Locking a period fixes it: matched lines in it cannot be changed, and reopening is recorded.
Locking is a separate permission from matching, on purpose.
The F5 laid out box by box at 9%, with every figure drillable to the entries behind it — including blocked input tax in Box 5 rather than Box 7, which is the one most often put in the wrong place.
Prepared for filing. You still file it.
One journal moves the year’s result into retained earnings, and the year shuts. Afterwards nothing dated inside it can be added, edited or deleted — which is what makes the figures you filed still the figures you filed.
Reopening takes a reason, and the reason goes in the trail.
4000Reports
Every figure on every report is summed from journal lines the moment you open it. There is no month-end process that has to have been run first, and no cached total that can quietly go stale.
Any period, with a comparison. Income, cost of sales, operating and other costs, gross and net.
As at any date, with retained earnings and the year’s result shown separately — and the difference stated rather than assumed.
Every account with a balance, debits and credits, and whether it adds up.
By customer and supplier, with unapplied credit notes on the report — because a credit note that has not been set against anything is real money the control account already knows about.
What is in the bank, and what the invoices and bills already entered do to it week by week. Money that is already overdue is kept out of the running line unless you ask for it.
Box by box at 9%, each figure drillable to the entries behind it.
Cost, accumulated depreciation and book value, tied back to the ledger accounts, with the difference shown.
Every entry, approval, match and change, filterable by area and by person. Append-only.
Two of these can legitimately differ from the ledger — the asset register and the aged reports are built from documents rather than from journals. Both show the tie-out on the screen, with the difference in figures. A report that quietly disagrees with the balance sheet is worse than one that says it does.
5000Control
The useful question about an accounting system is not what it lets you do. It is what it lets one person do quietly.
Transactions, bank, reports, people, settings — each with view, edit and approve. Every page and every download checks its own; a standing test derives the list of routes from the filesystem and fails if one is added without a guard.
Above the limit, the person who entered it cannot also approve it. Checked where the entry is posted rather than where the button is drawn, so it holds whichever door the request came through.
Matching the bank is bookkeeping. Locking the period says it has been checked, and the person who did the matching is not always the person who should be saying so. The two are different permissions.
Who did what, when, to which record, with what changed. The table refuses updates and deletes — not by convention, by trigger — so an inconvenient month cannot be tidied afterwards by anybody, including us.
6000Singapore
Every decision below makes this software worse for a company somewhere else. That is the trade, and it is worth saying out loud rather than implying it works everywhere.
7000Honestly
Worth reading before the pricing rather than after the first week. If one of these is the thing you need, this is not the product for you yet — and that is a better outcome for both of us than finding out in month two.
Singapore payroll means CPF by age and residency, SDL, the self-help group funds, IR8A and AIS. It is a regulated product of its own, and a wrong rate costs you penalties, not us. Run payroll where you run it now and post the journal here.
You import a CSV. There is no live connection to a bank, so the statement is as current as the file you downloaded. The import is careful about it — it shows you the parsed rows before writing anything, and it will not import the same line twice.
There is no importer. Opening balances and the chart of accounts are entered at setup; history stays where it is. Starting at a year end is the least painful moment.
Everything is in Singapore dollars, and the database enforces it. Foreign-currency invoicing needs rates, revaluation and a translation reserve to be right, and half of that is worse than none.
The aged debt report tells you who is late. Sending the reminder is still yours to send.
Statement matching is suggested by comparing amounts, dates and references, and a bank rule is a phrase you wrote down. Both show their working, and neither posts anything without you. There is no model deciding what an expense is.
The list is kept current deliberately. If something on it ships, it moves up the page; the terms and privacy notice are written the same way, and say plainly where they are still waiting on a lawyer.
