IN BRIEF

A month-end bookkeeping close is the fixed set of reconciliations and reviews a business runs before treating a month's accounts as finished — bank and GST tie-outs, TDS and payroll checks, ageing reviews, cash verification and recurring journals — so errors are caught in the month they occur, not at audit.

Most bookkeeping errors are not made in the month they are discovered. They are made quietly, weeks earlier — a missed invoice, a payment entered twice, a credit nobody chased — and they surface at audit time, or in a notice, when fixing them costs ten times the effort. A month-end close is how you stop that. Nine checks, run in the same order every month, turn your books from a pile of entries into a record you can defend.

None of this needs new software or a bigger team. It needs one fixed afternoon and the discipline to finish the list before the month is declared closed.

1. Reconcile every bank account to the last day of the month

Match the bank statement to the bank book, line by line, up to the month's final day — including the payment-gateway and UPI settlement accounts, which is where small differences like to hide. Every unexplained gap gets a reason written next to it while someone still remembers it. A difference you cannot explain in the first week of the next month becomes a mystery by the third.

2. Agree the sales register with the GST returns

Every invoice in the books should be sitting in GSTR-1, and every credit note you issued should be recorded in both places. Compare the month's taxable turnover in the sales register against what the returns carry. If the two disagree, one of them is wrong — and the return is the one the department reads first.

3. Tie the purchase register to GSTR-2B

Input tax credit today lives or dies on GSTR-2B: credit that does not appear there cannot be claimed, however genuine the purchase. Match the purchase register against the month's 2B and list every invoice that is in your books but missing from the statement. That list is your chasing list — send it to suppliers while the month is still fresh, not in November when the year's credit window is closing. Our Tally GST reconciliation checklist walks through the mechanics of this match.

4. Check TDS deducted against TDS payable — and last month's deposit

The TDS ledger should agree, to the rupee, with what your expense and salary entries say was deducted. Then confirm the previous month's TDS actually reached the government: deducted tax is deposited by the 7th of the following month, and March deductions by 30 April. A deducted-but-not-deposited balance sitting in the books is interest quietly accumulating, and it is the easiest item on this list to verify.

5. Close payroll before you close the books

Book the month's salary cost even if payday falls in the next month, and agree the PF and ESI payable balances against the payroll register. Salary is most small companies' largest cost; a month closed without it is a month whose profit figure means nothing. It also keeps the statutory payables honest, instead of letting them drift into a year-end lump nobody can split.

6. Read the receivables and payables ageing once — properly

Not a glance. A read. Who has crossed 45 days, who has crossed 90, and what is being done about each name. On the payables side, watch the invoices ageing towards 180 days unpaid: beyond that point, the GST credit you claimed on them comes back into question. Ageing reports are free. The surprises they prevent are not.

7. Count the cash

Physical cash in the drawer or the safe, counted on the last day, agreed to the cash book. It takes five minutes and it is the check small offices skip most. Cash differences found monthly are mistakes; cash differences found yearly look like something worse. Count it, note it, have a second person initial the note.

8. Post the entries that belong to every month

Rent. Depreciation. Interest on loans. Prepaid expenses releasing their month's share. The accruals for bills that always arrive late — electricity, professional fees, the annual software renewals. These are the entries that make one month comparable with the next, and they are the first ones dropped when the month gets busy. A standing list of recurring journals, ticked off, fixes that.

9. Clear the suspense and director accounts — or write down why not

Every office has a suspense ledger where doubtful entries go to rest. At month-end it should be empty, or every balance in it should carry a one-line explanation and an owner's name. The same goes for director and partner current accounts: money moving between the company and its owners, unexplained, is the first thing an auditor — or a due-diligence team — pulls on. Zero or explained. Those are the only two acceptable states.

Do these nine for three months running and something changes: the year-end stops being an excavation. Your auditor gets clean books, your GST annual reconciliation starts from figures that already agree, and you stop paying professionals to reconstruct a year you lived through once already.

This monthly close is the backbone of how we run bookkeeping for clients — if your books currently close only when the auditor asks, bring them to us and we will put the rhythm in place.
