Every month, without exception. That is the absolute minimum. If your business runs a lot of transactions through its bank account and credit cards, weekly is even better.

Reconciliation is how you confirm that what your accounting software shows matches what the bank actually processed. It catches duplicate charges, missing deposits, unauthorized transactions, fees you didn’t expect, and payments that never cleared. These things happen more often than most business owners realize. A vendor might run your card twice. A customer’s check might bounce without you noticing. Your bank might charge a fee that doesn’t match what you agreed to. If you’re not reconciling regularly, these problems sit undetected until they snowball into bigger issues.

The compounding effect of falling behind is real. When you reconcile monthly, you’re looking at 30 days of activity while it’s still relatively fresh in your mind. You can remember that $300 charge was a supply run or that the $1,200 deposit was from a specific client. Wait three or six months and you’re guessing. The longer the gap, the more time it takes per month to sort through, and the more likely you are to misclassify something or miss a discrepancy entirely.

Weekly reconciliation makes sense for businesses that process dozens of transactions per week or handle cash. Restaurants, retail shops, service businesses with daily card payments. Catching a problem on day five is very different from catching it on day thirty. Fraud alone is worth the extra attention. Most banks have a limited window for disputing unauthorized charges, and that window shrinks fast if you’re not watching.

Even if your transaction volume is low, monthly reconciliation protects the accuracy of your financial reports. Your profit and loss statement is only as reliable as the data behind it. If your books don’t match your bank, every decision you make based on those numbers is built on bad information. That matters when you’re deciding whether you can afford to hire, invest in equipment, or take on a new project.

If reconciliation keeps slipping because you’re busy running your business, that’s a sign you need help.
