Bank Reconciliation Explained

Updated: 2026-03-04

Bank reconciliation is the habit that keeps your books from drifting away from reality. It’s how you verify that what your accounting system says happened is the same as what your bank says happened.

What reconciliation does

A reconciliation compares:

• Beginning balance (bank vs books)
• Deposits / inflows
• Withdrawals / outflows
• Ending balance

When you reconcile, you confirm that:

• every deposit is recorded once
• every payment is recorded once
• missing items are identified and fixed
• financial reports can be trusted

The standard bank reconciliation workflow

1) Choose the statement period

Most businesses reconcile each bank statement (monthly). Use the statement end date as your reconciliation cutoff.

2) Match deposits

Compare deposits in your accounting system to deposits on the bank statement.

Common outcomes:

• Match → mark cleared
• Missing in books → add it (example: interest)
• Missing in bank → deposit in transit (timing)

3) Match withdrawals and payments

Compare withdrawals, ACH payments, checks, card payments (if they run through the account), and fees.

Common outcomes:

• Match → mark cleared
• Missing in books → enter it (example: bank fee)
• Wrong amount → correct the entry
• Duplicate → remove/void the extra entry

4) Identify timing items

Two normal timing differences are:

• Deposits in transit: recorded in books but not yet shown by the bank
• Outstanding checks: checks/payments issued but not yet cleared

These are not “errors” — just timing.

5) Resolve the difference

If the ending balances don’t match, the cause is usually one of these:

• missing bank fees or interest
• duplicate entry
• wrong date (transaction recorded in wrong period)
• wrong amount
• missing transaction entirely

Work systematically:

• search for duplicates
• check amounts first
• then check dates
• then check missing transactions

6) Lock the reconciliation

Once reconciled, don’t change cleared transactions. If something needs correction later, post an adjusting entry instead of editing history.

How often to reconcile

• Monthly: minimum standard for clean bookkeeping
• Weekly: better for high volume, tighter cash control, or multiple payment processors

If reports matter, reconciliation comes first.

Common mistakes

• Reconciling only when something “looks wrong”
• Editing old reconciled transactions (breaks audit trail)
• Ignoring bank fees/interest
• Mixing personal and business spending
• Using the wrong cutoff date

What reports become reliable after reconciliation

After your bank accounts are reconciled, these reports are far more trustworthy:

• Profit & Loss (P&L)
• Balance Sheet
• Cash flow projections
• AR and AP aging (indirectly—because payment timing is correct)
