Bank Reconciliation: the Monthly Routine Nothing Replaces

Your books say the bank balance is one number. Your bank statement says another. Both are looking at the same account, in the same month, and they disagree — sometimes by a few hundred rupees, sometimes by lakhs. A bank reconciliation statement, the BRS, is the monthly statement that explains that disagreement, line by line, until every rupee of difference has a name. It is not glamorous work. Nothing in bookkeeping protects you more. Our service page calls it out in its section on bank reconciliation — the routine nothing replaces, and this post shows what the routine actually catches and how it runs.

Why the two balances disagree in the first place

Your cash book and the bank's statement are two records of the same account, written by two different people at two different speeds. You record a cheque the day you issue it. The bank records it the day the payee presents it, which may be three weeks later. The bank debits charges the day they fall due. You learn about them when the statement arrives. Some difference, most months, is normal. An unexplained difference never is. Every difference belongs to one of three families, and the family decides what you do with it.

Timing differences. The entry is correct in one record and simply has not reached the other yet. Cheques you issued that the payee has not presented. Cheques you deposited that the bank has not yet credited. Gateway settlements that leave the provider on one date and land in your account on another. These need no correction in your books. They need watching, because a timing item that ages is no longer a timing item.

Bank-initiated entries. The bank moved money and told you afterwards, in the statement. Bank charges. Interest credited or debited. Standing instructions and auto-debits for EMIs, rent or insurance that you set up and half forgot. A customer who paid you directly into the account — a direct credit your books never saw because nobody raised an entry for a payment nobody announced. These belong in your books. The reconciliation is how they get there.

Errors. Yours or, occasionally, the bank's. An amount entered wrong — ₹45,900 recorded as ₹49,500. An entry posted twice. A payment recorded against the wrong account entirely, so the money looks present when it has gone. Errors are corrected in whichever record is wrong, with a proper narration, never by quietly editing history.

What the routine catches when it runs every month

Run the reconciliation monthly and it becomes the cheapest control in your business, because the bank statement is the one record you did not write yourself. It catches the honest mistakes first: the supplier payment entered twice in a busy week, the receipt recorded at the net amount when the gateway had already taken its fee, the bank charges that would otherwise sit unrecorded until the auditor's query letter arrives in October.

Then it catches the uglier shapes. A duplicate payment to a vendor — same invoice, paid once by cheque and once by transfer — shows up as money gone from the bank with only one entry in the books. A cheque amount altered after signing shows up as a bank debit that matches no entry you made. A payment diverted to a wrong, or newly changed, beneficiary shows up the same way: the bank moved, your books did not, and the gap is sitting in the reconciliation waiting for someone to ask about it. I am not quoting you percentages for how often this happens; nobody honestly can. I am telling you where it surfaces when it does. It surfaces here, in the unmatched list, within a month — or it surfaces years later, in a dispute, when surfacing costs you far more.

The monthly routine, step by step

1. Collect every statement. Every current account, every savings account the business uses, every credit card, every payment gateway settlement report. An account left out is an account unreconciled, and trouble prefers exactly those.
2. Start with the opening position. Take last month's reconciled position as your opening. If last month closed with explained items, this month's list should begin with those items and show which of them cleared.
3. Tick the matches. Match each statement line to a book entry — same amount, same value date or close to it, same party where the statement shows one. In software this is partly automatic; the human eye still has to clear the near-matches, because a wrong match hides a real difference behind a tick.
4. List everything unmatched, from both sides. Statement lines with no book entry. Book entries with no statement line. This list is the reconciliation. Treat it as the product, not as a by-product.
5. Book what belongs in the books. Bank charges, interest, standing instructions, direct credits from customers, a dishonoured cheque you had taken as received — pass the entries now, dated and narrated, so the cash book reflects reality. These items then leave the list because they are no longer differences.
6. Leave the timing items in the statement, with dates. Unpresented cheques and deposits in transit stay on the BRS, each with the date it arose. Anyone reading the statement should be able to see how old every open item is at a glance.
7. Chase the stale ones before you close. Any item older than a month gets a named owner and a next step — a call to the payee, a query to the bank, a check with the customer. Then close the month and file the signed reconciliation with the statement it belongs to.

Done this way, a small company's reconciliation is an hour or two of steady work. Done after six months of neglect, it is a week of archaeology — which is why the weekly recording habit in our guide to a bookkeeping routine for small businesses feeds straight into this monthly close.

"Reconciled" means explained, not forced

Here is the part people get wrong, so let me be plain. A reconciliation is finished when every difference is explained — when each open item has a cause, a date and an owner. It is not finished when the two balances are made to agree by inserting a balancing entry nobody can explain. That plug figure, parked in a suspense account and carried forward month after month, is worse than the difference it hides. The difference was information. The plug is a curtain over it.

Think of the two records as two guest lists for the same event, one kept by you and one kept at the gate. Reconciling is not rubbing out names until both lists show the same total. It is accounting for every name that appears on one list and not the other — this one is invited and has not arrived yet, that one walked in with a group and was never written down, this one is a spelling error for the same person. When every name has an explanation, the lists are reconciled, whether or not the totals happened to match before you started. That is the standard an auditor reads your BRS against, and it is the standard to hold your own team to.

The stale-cheque trap, and what to do with old items

One timing item has a legal expiry date, and missing it changes the conversation. Under an RBI direction in force since 1 April 2012, banks must not pay a cheque presented more than three months after the date written on it. The older six-month habit is gone. A cheque older than three months is stale, and the bank will return it unpaid.

For a cheque you issued, a stale item on your reconciliation is a question, not a windfall. Do not reverse it into income just because the bank can no longer pay it. Ask why the payee never presented it — a lost cheque, a dispute, a payment replaced by transfer and never cancelled in the books. If the amount is still genuinely payable, cancel the old instrument in your records and pay afresh. If it is not payable any more, record that decision and the reason for it, so the trail survives. For a cheque you received and failed to bank in time, the honest route is back to the drawer: return the stale instrument and ask for a fresh cheque or a direct transfer. There is no stamp or signature that revives a stale cheque at your bank's counter.

This is also why the ageing of open items matters more than the reconciliation total. A payee sitting on your cheque for ten weeks is a problem you can still solve with a phone call and a reissue. At four months, you are solving it with correspondence. Watch the dates, not just the amounts.

Who else reads this statement

Nobody in the Companies Act prescribes a monthly BRS, and I will not pretend otherwise. What Section 128(1) does require is that a company's books of account give a true and fair view, kept on an accrual basis under the double-entry system. A bank balance your books cannot tie to the bank's own record, month after month, is a poor witness for that duty. In practice, your statutory auditor will ask for the reconciliations early in the audit, lenders ask for them when they test your working capital, and anyone doing diligence on your company will ask. When the statements are ready, signed and explained, those conversations take minutes. When they are not, the same conversations take weeks and cost goodwill you did not need to spend.

If your reconciliations are a few months behind — or a few years — the honest fix is a catch-up done in order, month by month, until the current month closes clean. Our book-keeping team runs this routine for every account, every month, as part of the engagement: statements matched, differences explained, stale items chased and reported to you in plain words. Bring us the backlog. We will bring the list down to zero, and keep it there.
