  • Compare the same bank account and closing date.
  • Record missing bank charges, receipts and payments in the books where supported. List genuine timing differences separately. A reconciliation explains the difference; it should not create an unsupported expense simply to force the balances to agree.

The bank statement says one amount, while your accounting software shows another. That difference is a question to investigate, not an instruction to overwrite either number. A bank reconciliation explains how the two records connect.

Start with three matching details

Use the same bank account, currency and closing date. Compare the statement balance with the corresponding bank ledger, not with total cash across all accounts. A current-account available balance may also reflect holds or borrowing limits; establish what the bank figure represents. The worked example below uses positive deposit balances, not an overdraft.

Put each difference in the right category

How common differences are handled
Difference What to check Usual next step
Bank charge absent from books Statement, advice and tax invoice where relevant Record the supported charge once
Deposit recorded but not yet credited Deposit proof and subsequent bank entry Explain the timing difference
Cheque issued but not yet presented Cheque record, validity and later clearance Explain outstanding presentation
Unknown receipt Payer, bank reference and customer allocation Investigate before calling it sales
Duplicate book entry Import log and original transaction Correct the duplicate with an audit trail

A fictional reconciliation, step by step

Assume the books show ₹3,00,000. Bank charges of ₹1,500 and interest income of ₹400 have not been recorded. The books also include a ₹30,000 deposit not yet credited and a ₹20,000 issued cheque not yet presented.

From book balance to statement balance
Working Amount
Book balance before supported updates ₹3,00,000
Less missing bank charges ₹1,500
Add missing interest income ₹400
Updated book balance ₹2,98,900
Less deposit not yet credited ₹30,000
Add issued cheque not yet presented ₹20,000
Expected bank-statement balance ₹2,88,900

The updated books remain ₹2,98,900. The ₹10,000 net timing difference explains why the statement shows ₹2,88,900. Do not record another ₹10,000 expense to force agreement. When the pending items clear, they should disappear from the reconciliation without duplicating the original book transaction.

Make the checking process repeatable

  1. Begin with the previous approved reconciliation and identify items still open.
  2. Match receipts and payments using amount, date and transaction reference.
  3. Inspect one-to-many settlements: a platform payout may contain several invoices and deductions.
  4. Record supported book corrections, then prepare the remaining timing bridge.
  5. Assign an owner and next review date to each unresolved item.

Old outstanding items need evidence

A deposit described as “in transit” for several months needs follow-up. An old cheque may have expired, been cancelled or been replaced. Establish what actually happened before changing the bank ledger or the amount owed to the supplier. A clearing account can temporarily organise identified settlements; it should not become a permanent hiding place for differences.

Questions that often come up

Does agreement prove there is no error? No. Offsetting mistakes can cancel numerically. Review the individual transactions and unusual entries as well as the final total.

Should every customer receipt be booked as fresh sales? No. It may settle an existing invoice, be an advance or relate to another transaction. Identify it before posting.

Can I reconcile only at year-end? Monthly reconciliation is a useful starting routine; high transaction volumes or risk may justify more frequent checks. This is a management recommendation, not a universal statutory frequency.

What to prepare for a review

Keep the statement, bank ledger, previous reconciliation, payment references, deposit evidence and an unresolved-item list. A clear explanation supported by records is more useful than an unexplained zero difference. For a wider record review, see our month-end closing guide.
