The Bookkeeping Process and Month-End Closing Checklist

Good bookkeeping isn't one big job at year-end. It's a repeating process, a bookkeeping cycle, that runs every month. Get the cycle right and VAT returns, Corporate Tax returns and audits become routine.

The bookkeeping process, step by step

1. Collect source documents. Sales invoices, supplier bills, receipts, bank statements, payroll records and contracts. No document, no entry.
2. Record transactions. Enter each transaction with the correct date, amount, category and VAT treatment, ideally daily or weekly.
3. Post to the ledger. Accounting software does this automatically using double-entry: every transaction affects at least two accounts.
4. Reconcile accounts. Match your records to bank, card and supplier statements.
5. Make month-end adjustments. Accruals, prepayments, depreciation and corrections.
6. Review the trial balance. Check that balances make sense: no negative bank balances, no forgotten suspense items.
7. Produce reports. Profit and loss, balance sheet and cash summary.
8. Close the period. Lock the month so no one changes it by accident.

Day-to-day bookkeeping

Daily (or weekly) bookkeeping keeps the month-end short. The goal is to have nothing left to "find" at month-end:

• Issue sales invoices as soon as work is done or goods are delivered.
• Capture receipts the same day with a phone app.
• Match bank feed transactions to invoices and bills.
• Record advance payments from customers as a liability until the work is delivered, and advance payments to suppliers as a prepayment.

This is sometimes called real-time bookkeeping. It doesn't need to be literally real-time: weekly is enough for most small businesses.

Month-end closing checklist

Use this checklist each month. When every item is ticked, the month is closed.

• ☐ All sales invoices for the month issued and recorded
• ☐ All supplier bills and receipts recorded, with tax invoices on file
• ☐ Every bank, card and payment-gateway account reconciled to the statement
• ☐ Cash on hand counted and recorded
• ☐ Customer balances reviewed; overdue invoices chased
• ☐ Supplier statements reconciled
• ☐ Payroll and WPS entries posted and matched to the salary transfer
• ☐ Accruals and prepayments recorded (e.g. utilities not yet billed, annual rent paid in advance)
• ☐ Depreciation posted for fixed assets
• ☐ VAT control account checked against transactions
• ☐ Inventory updated (if you hold stock)
• ☐ Trial balance reviewed for unusual balances
• ☐ Profit and loss, balance sheet and cash report produced
• ☐ Period locked in the accounting software

Quarter-end: add the VAT steps

• Run the VAT report and compare it to the VAT control account.
• Check reverse-charge entries for imported services and goods.
• Confirm you hold tax invoices for all input VAT claimed.
• File and pay by the 28th day after the quarter ends. See the VAT due date calendar.

Year-end: add the Corporate Tax steps

• Prepare year-end schedules: fixed assets, accruals, prepayments, loans and related-party balances.
• Agree balances with your auditor, if you need an audit.
• Prepare financial statements and tax adjustments.
• File the Corporate Tax return within nine months. See the Corporate Tax return guide.

Common bookkeeping process mistakes

• Recording from bank statements only, without invoices: VAT can't be supported.
• Leaving a "suspense" account full of unexplained items.
• Not reconciling credit cards and payment gateways.
• Recording customer advances as sales.
• Never locking periods, so old months change after returns are filed.
