Sole trader bookkeeping checklist: what to organise each month

A short monthly bookkeeping routine can prevent a stressful year-end catch-up and give you a clearer view of the business.

1. Record every sale

Check invoices, online platforms, cash and bank receipts. Keep a list of invoices still unpaid.

2. Save expense evidence

Keep receipts and supplier invoices and add a brief business description where needed.

3. Separate personal transactions

A separate account makes records easier to follow. Identify personal spending and drawings clearly.

4. Reconcile the bank

Check for missing income, duplicated imports, bank fees and incorrect dates or amounts.

5. Review money owed and bills due

Follow up overdue customers and include upcoming supplier bills in cash planning.

6. Keep records consistently

See HMRC’s self-employed record-keeping guidance.

7. Check Making Tax Digital

Check HMRC’s latest timetable.
