Books that are checked every month are far easier to keep right than books that are repaired once a year. This checklist gives small businesses a repeatable month-end routine. Adapt it to your own volume and systems.
Before you start
- Collect all bank, wallet and card statements for the month.
- Gather sales invoices, purchase bills, expense receipts and payment confirmations.
- Set a cut-off date so that everyone knows which transactions belong to the month.
The checklist
- Record all sales and purchase invoices dated in the month.
- Enter expenses and attach or reference the supporting document.
- Record all bank receipts and payments and allocate each to the right account.
- Reconcile every bank and cash account to the ledger and list any unreconciled items.
- Review customer balances, note overdue invoices and decide who to follow up.
- Review supplier balances and confirm what is due and when.
- Check any tax withheld or deducted from your receipts and keep the related certificates or evidence.
- Review payroll entries, loans and other recurring items for completeness.
- Look for unusual or duplicate entries and unexplained round amounts.
- Produce a profit and loss statement and balance sheet and read them for anything unexpected.
- Back up the files and lock the period if your system allows it.
What good looks like at the end of the month
| Output | What it confirms |
|---|---|
| Bank reconciliation | Bank balances agree to the books and differences are explained |
| Receivables list | You know who owes you and how long it has been outstanding |
| Payables list | You know what is due and can plan cash |
| Profit and loss statement | Revenue and costs are recorded in the right period |
| Balance sheet | Assets, liabilities and equity are complete and balance |
Common mistakes to avoid
- Mixing personal and business payments in the same account.
- Leaving receipts for later and then losing them.
- Skipping the reconciliation because the balance looks about right.
- Posting entries into the wrong period, which distorts monthly results.
