What it means
Reconciling means comparing your books to an independent record of the same activity and making the two agree. For a bank account, you take the bank statement and match each deposit and withdrawal to an entry in your ledger. Credit cards, Stripe, payroll and loans get the same treatment.
Matching ending balances isn't enough. Two errors can cancel each other out, so every line on one side has to be matched or explained on the other.
Differences come in a few kinds. Timing items are real transactions one side hasn't caught up with yet, like a deposit recorded on the 31st that the bank shows on the 1st; they need no entry. Items only the bank knows about, like fees and interest, need an entry in the books. Errors, like a duplicate or a wrong amount, need a correction.
Payment processors add a step. A Stripe payout is net of fees and refunds and can cover several days of charges, so it's split into gross sales, fees and refunds before it's matched.
Reconciling March, Acme matches every line on the bank statement except a $45 wire fee that was never recorded. It books the fee to bank fees, and cash in the ledger now matches the statement.
It also has a $2,000 customer payment recorded on March 31 that the bank shows on April 1. That's timing, so it stays on the reconciliation as a deposit in transit. If it doesn't appear on April's statement, someone investigates.
A bank reconciliation is usually the support behind the lead schedule for cash. It's the first step of the monthly close, and it leaves an audit trail of which lines matched which entries.
Why it matters. An unreconciled balance is an estimate. Reconcile monthly and a missing payment or a double charge shows up within weeks instead of at year end.
The entry, worked
Reconciling March, Acme finds a $45 wire fee on the bank statement that was never recorded.
| Account | Debit | Credit |
|---|---|---|
| Bank fees | $45.00 | |
| Cash | $45.00 | |
| Total | $45.00 | $45.00 |
The fee is now in the books, and cash in the ledger matches the bank statement.
Common questions
How often should accounts be reconciled?
Monthly, as part of the close, is the usual standard. Busy accounts are sometimes reconciled weekly so problems surface sooner.
Why doesn't my Stripe deposit match my revenue?
A payout is net of fees and refunds and can cover several days of charges. Reconciling it records the gross revenue, the fees and the refunds separately.
What is an outstanding check on a bank reconciliation?
A check or payment you've recorded that the bank hasn't cleared yet. Like a deposit in transit, it's a timing item that needs no entry. If it's still outstanding after a few months, find out why, and void and reissue it if the payee never got it.
