The habit that keeps every other report trustworthy
It's one of the least exciting words in accounting.
Reconciliation. And yet it's arguably the single habit that keeps everything else about your numbers trustworthy.
Reconciling simply means checking that your accounting records match what actually happened in your bank account. Skip it, and every other report — your P&L, your GST position, your sense of what the business is doing — is only as accurate as your assumptions.
The short answer
For most small businesses, weekly reconciliation is a strong habit, with monthly as the practical minimum. If you're registered for GST, reconciling before each BAS lodgement isn't optional — it's how you know the figures you're reporting are actually right.
How often, by situation
| Your situation | Suggested frequency |
|---|---|
| High transaction volume, tight cash position | Weekly — or even more often during a cash-sensitive period |
| Moderate volume, steady trading | Fortnightly to monthly |
| Very low volume, simple accounts | Monthly, as an absolute minimum |
| Registered for GST | Always before each BAS lodgement, regardless of your general rhythm |
What reconciling actually catches
Errors, before they compound. A miscategorised transaction found this week is a two-minute fix. Found six months later, it may have already distorted several reports.
Missing transactions. Something that hit the bank account but never made it into your accounting records — easy to miss without a regular check.
Duplicate entries. Especially common when manual entry and bank feeds overlap.
Unauthorised or unexpected transactions. Regular reconciliation is also a basic fraud and error control — unusual activity is far easier to spot weekly than annually.
A genuinely current picture. You can only trust “what's my cash position right now” if the records behind it are up to date.
What it actually involves
At its core: comparing every transaction on your bank statement against your accounting records, confirming they match, and investigating anything that doesn't. In modern accounting software, much of this is semi-automated through bank feeds — your role becomes confirming and categorising rather than manually re-entering.
Why monthly is a floor, not a target
Monthly reconciliation is enough to avoid falling seriously behind, but it means you're potentially making decisions on a cash position that's up to four weeks stale. For a business watching cash flow closely, that gap can matter — which is why weekly is the stronger habit where volume justifies it.
A quick self-check
When did I last reconcile my business bank account?
Do I know, right now, whether my accounting records match my actual bank balance?
Have I reconciled fully before my last BAS lodgement, or estimated?
Is my current frequency matched to how tight my cash position actually is?
When should you get professional help?
you're not confident your records currently match your bank account;
reconciliation differences keep appearing and you can't identify the cause;
you want a bookkeeper to handle this on a consistent schedule rather than relying on finding the time yourself; or
you're setting up accounting software and want reconciliation configured properly from the start.
