Running the business Accounts

Month-end closing checklist

Closing the books every month means getting all entries in, reconciling bank and parties, checking stock and taxes, and reviewing a few key reports. It turns year-end from a three-week scramble into a routine, and it gives you numbers you can act on while they still matter.

1. Get all entries in

All sales invoices, credit notes and delivery challans for the month entered.
All purchase bills received entered; follow up on bills for goods already received.
Expenses entered with bills: rent, electricity, telephone, freight, repairs.
Salaries, wages and incentives for the month booked.
Cash vouchers from petty cash entered; see petty cash management.
Pending sales orders and purchase orders reviewed; close the ones that are dead.

2. Bank and cash

Reconcile every bank account with the statement; list cheques issued but not cleared and deposits not yet credited. See bank reconciliation basics.
Enter bank charges, interest and direct debits from the statement.
Count physical cash and match it with the cash book.
Investigate any receipt in the bank that is not identified to a party.

3. Receivables and payables

Adjust all receipts against specific bills, not "on account".
Review receivables ageing; list parties for follow-up.
Send statements to major customers; resolve differences they point out.
Review payables ageing; check dues to micro and small suppliers against the payment limit (see the MSME 45-day rule).
Match statements from main suppliers with your ledger.

4. Stock

Check for negative stock items; these usually mean a missing purchase or wrong item on a bill.
Count a sample of high-value items and compare with books.
Enter stock transfers between godowns or branches.
Note slow-moving items for purchase decisions.

For businesses with several godowns or branches, confirm that goods in transit at month end are recorded at the sending or receiving end, not missing from both.

5. GST and TDS

Check GSTINs and place of supply on B2B invoices.
Prepare GSTR-1 from your sales data and review it before filing.
Reconcile purchase register with GSTR-2B for input tax credit.
Work out GST payable for GSTR-3B.
Deduct and deposit TDS on applicable payments (rent, contractors, professional fees and others).

For monthly filers, GSTR-1 is generally due by the 11th and GSTR-3B by the 20th of the following month, and TDS deposited by the 7th; quarterly schemes and some states have different dates, and dates can change by notification. Check gst.gov.in and incometax.gov.in, and see the GST compliance calendar. This is general information, not tax advice.

6. Review the numbers

Report	What to look for
Profit & Loss (month and year to date)	Sales and gross margin vs last month and last year; unusual expenses
Balance Sheet	Debtors, stock and creditors trend; bank borrowing
Trial Balance	Suspense balances, wrong-side balances
Receivables ageing	Share over 60 days
Cash forecast	Next 4–13 weeks of receipts and payments

Then lock the month: agree that no one edits entries in a closed month without the owner's or accountant's approval.

A suggested month-end calendar

Working day	Task
Day 1–2	Finish entries; bank and cash reconciliation
Day 3–4	Party statements, receivables and payables review; stock checks
By the 7th	TDS deposit for the previous month
Day 5–8	GSTR-1 review and filing; GSTR-2B reconciliation
Day 9–10	Owner reviews reports; month locked

Adjust the days to your own due dates and team size.

Closing the month with Tally and Cashflow OS

TallyPrime remains where entries are made and corrected. Cashflow OS makes the review part faster: the Profit & Loss, Balance Sheet, Trial Balance, Day Book, cash and bank books, outstanding with ageing and a cashflow forecast are on your phone and web, with Excel and PDF export to share with your CA. GSTR-1 and GSTR-3B views are prepared from the Tally data, with JSON download for the portal; filing is still done on the GST portal. See financial reports.

Avoid these

Common mistakes

MistakeLeaving entries for the last days of the month
Do this instead
Enter sales, purchases and expenses during the month so closing is review and reconciliation, not data entry.
MistakeKeeping receipts 'on account' instead of against bills
Do this instead
Adjust each receipt against the specific bills it pays, or the ageing report and party follow-ups will be wrong.
MistakeFiling GST returns from books that are still changing
Do this instead
Close and review the month first, then prepare GSTR-1 and GSTR-3B from the closed figures to avoid mismatches.
MistakeAllowing edits in a closed month without approval
Do this instead
Agree that closed months are changed only with the owner's or accountant's approval, and restrict user rights in your software.

Questions people ask

How long should month-end closing take?

For a small business with entries kept up to date during the month, a few days is realistic. If it takes longer, entries are probably being left for month end.

Who should do the month-end close?

Your accountant or accounts staff do the entries and reconciliations; the owner should review the reports and approve adjustments.

Is a monthly stock count necessary?

A full count monthly is rarely practical. Count high-value items monthly and do a full count once or twice a year.

What does locking a month mean?

It means agreeing that entries dated in a closed month are not changed without approval. User rights in your accounting software can usually restrict who may alter past entries; ask your Tally partner or accountant to set them up.

Should I close the month before GST returns are filed?

Close the books first, then prepare returns from the closed figures. Filing from data that is still changing is a common cause of differences between books and returns.

What should I do if the bank reconciliation does not match?

List cheques issued but not cleared and deposits not yet credited, then enter any bank charges, interest or direct debits from the statement. Whatever is left is usually a missing or wrong entry.

Why does negative stock matter at month end?

Negative stock usually means a purchase was not entered or the wrong item was billed. It distorts stock value and gross margin, so fix it before reviewing profit.

Can I use month-end closing to plan cash?

Yes. Once receivables and payables are up to date, a simple forecast of the next few weeks' receipts and payments shows whether you will be short of cash.
