How to Reconcile Bank Accounts

Reconciliation is the single most important monthly habit in bookkeeping. It's how you prove the books match reality — and it's the first thing a CPA checks.

What reconciliation actually proves

A reconciliation confirms that every transaction the bank recorded is in your books, and every transaction in your books actually cleared the bank. If they don't tie, the financials are wrong — full stop.

The monthly workflow

  • Download the bank statement for the period (calendar month)
  • Open the matching account in your bookkeeping software
  • Enter the ending statement date and ending balance
  • Check off each transaction that appears on both sides
  • Confirm the difference is $0 before closing

Common reasons it doesn't reconcile

  • Transactions entered twice (duplicates)
  • A deposit or payment missing from the books
  • Wrong amount entered (transposed digits)
  • Wrong date — transaction is in a different period
  • Manual journal entry posted to the bank account by mistake
  • Prior month was force-balanced — the error rolls forward

Reconcile credit cards and merchant accounts too

Every account with its own statement gets its own reconciliation: credit cards, lines of credit, loans, Stripe, Square, PayPal. Each one is a separate trust-but-verify checkpoint.

Lock the period when you're done

  • Set a closing date in your software to prevent backdated edits
  • Save a PDF of the reconciliation report with the statement
  • Add reconciliation date to your monthly close checklist

Frequently asked

How often should I reconcile?

Monthly, ideally within a week of the statement date. Quarterly or annual reconciliations almost always uncover errors that are painful to track down.

What if I can't get to $0?

Don't force-balance with a plug entry. Work backward through the period and check the prior reconciliation. A small unresolved difference usually means a duplicate or a missing entry, not a math error.
