How to Reconcile Your Bank Account as a Small Business Owner (And Why It Matters)

Most small business owners check their bank balance and call it “reconciled”.

What bank reconciliation actually is

Reconciling is the process of comparing every transaction in your accounting records against your bank statement line by line and confirming they match. Every deposit, every payment, every fee, accounted for and verified.



It is not about checking your balance. It is about confirming that your records are accurate and complete.

Why it matters

Without reconciling, errors live in your books indefinitely. A transaction recorded twice. A payment that cleared the bank but was not recorded in your system. An expense that was never captured. None of these announce themselves; they just quietly make your numbers less accurate month after month.


By the time you notice something is wrong, you may be looking at months of financial reports that were not right and months of decisions made on inaccurate information.


Reconciling monthly catches these errors before they compound. It is the check that confirms your books reflect reality.

How to reconcile your bank account

The process is straightforward when done monthly:


Start with your bank statement for the period. Note the opening balance, closing balance, and every transaction in between.


Open your accounting records for the same period. Compare every transaction against the bank statement.


Investigate every discrepancy. A transaction on the statement not in your records needs to be added. A transaction in your records not on the statement needs to be investigated; it may not have cleared yet, or it may have been recorded incorrectly.

How long it takes

For a small business with low transaction volume, for example,  under 50 transactions per month, reconciling takes approximately 20-30 minutes. For higher-volume businesses, it takes longer. Either way, it is the most valuable 20-30 minutes in your monthly bookkeeping routine.

What happens when you skip it

Skipping reconciling for one month is recoverable. Skipping it for several months means catching up on a backlog of unmatched transactions, which takes significantly longer and carries a higher risk of errors going undetected.

Credit cards too

Bank reconciliations are not just for checking accounts. Every business credit card should be reconciled monthly against its statement using the same process. Credit card statements often contain fees, interest charges, or possible fraudulent transactions that only surface during the reconciliation process.

Can your bookkeeper do this for you?

Yes, and they should. Monthly reconciliations of all bank and credit card accounts is a standard part of any professional bookkeeping engagement. If your current bookkeeper is not reconciling your accounts monthly, that is worth asking about.


At KW Bookkeeping, monthly reconciliations are included in every bookkeeping engagement. Your accounts are reconciled, your records are verified, and your books reflect reality, every month without exception.

Frequently Asked Questions

  • How often should I reconcile my bank account?

    Monthly is the standard. Some businesses with high transaction volumes reconcile weekly. Reconciling quarterly or only at year-end means errors have significantly more time to compound.

  • What if my records do not match my bank statement?

    Do not move on until the discrepancy is resolved. Common causes include transactions recorded in the wrong period, duplicate entries, expenses not captured in your records, or payments that have not yet cleared. If you cannot identify the source of a discrepancy, it is worth flagging to a bookkeeper; unresolved reconciling items are a sign something in the records needs attention.

  • Do I need accounting software to reconcile?

    No, you can reconcile manually using a spreadsheet. But accounting software like QuickBooks makes it significantly faster by importing bank transactions automatically and flagging unmatched items. For any business with more than a handful of transactions per month, the time savings is worth it.
