Set the system up once
Start with a separate business bank account where appropriate, a chart of accounts that matches how the business operates, and one place for invoices and receipts. Connect feeds carefully and set opening balances before relying on reports.
Decide who raises sales invoices, approves purchases, uploads evidence, reconciles accounts, submits returns, and reviews the result. Clear ownership prevents duplicated or missed work.
- Keep business and personal transactions separate.
- Use consistent customer, supplier, VAT, and expense naming.
- Restrict access appropriately and turn on multi-factor authentication.
- Document the accounting method, VAT scheme, year end, and filing deadlines.
The recurring checklist
Adjust the frequency for transaction volume and risk. A busy retailer may need daily controls where a consultant can work weekly.
| Frequency | Core tasks | What good looks like |
|---|---|---|
| Daily or weekly | Issue invoices, capture receipts, import transactions, chase overdue debts, record cash sales | Evidence is attached and unusual items are flagged while memories are fresh |
| Monthly | Reconcile every bank/card account, review debtors and creditors, post payroll, check VAT coding, review profit and cash | Statement balances agree and unexplained differences are resolved |
| Quarterly | Review VAT or MTD totals, tax reserve, fixed assets, loans, director balances and forecast | Submitted totals reconcile back to the ledger and working papers |
| Year end | Complete all reconciliations, stock count, accruals/prepayments, asset review and accountant handover | A clean trial balance is supported by schedules and evidence |
Reconcile control accounts, not just the bank
A bank reconciliation checks that the bookkeeping balance agrees to the external statement. Also review payment processors, credit cards, petty cash, loans, payroll liabilities, VAT, customer balances, supplier balances, and director or owner accounts.
Old balances often reveal duplicate entries, missing refunds, payments posted to the wrong customer, or costs recorded without an invoice. Set a threshold and investigate aged or unusual items every month.
Review the numbers for business decisions
Bookkeeping is not complete when every bank line is categorised. Review sales, gross margin, overheads, cash balance, overdue invoices, upcoming tax, and comparison with the prior period or forecast.
Ask what changed and why. A rising profit with falling cash could reflect slow customer payments, stock purchases, loan repayments, tax, or owner withdrawals. The bookkeeping should make that explanation visible.
Keep digital evidence and a clear audit trail
Attach invoices or receipts to transactions where possible and preserve approvals, contracts, mileage logs, stock counts, and business/private calculations. Avoid changing historic entries without a note explaining why.
Making Tax Digital for Income Tax requires qualifying users to create and keep digital records of relevant self-employment and property income and expenses. Spreadsheet use may require digital links and compatible bridging or submission software.
Prepare an efficient accountant handover
Before handing over, complete reconciliations and provide a short exceptions list. Include bank statements covering the year end, loan statements, payroll reports, VAT returns, stock values, fixed-asset purchases, finance agreements, and explanations for unusual transactions.
Do not guess at unclear items to make the report look tidy. Put them in a query list with the amount, date, supplier or customer, and what evidence is available.
Frequently asked questions
How often should a small business do bookkeeping?+
Weekly is a sensible baseline for many small businesses, with monthly reconciliations and reporting. Businesses with high transaction volume, cash sales, or tight cash flow may need daily attention.
Is a bank feed enough evidence?+
No. It shows money moving but may not establish what was purchased, the VAT treatment, or the business purpose. Keep invoices, receipts, and relevant supporting records.
What should be reconciled at month end?+
At minimum, reconcile bank and card accounts. Also review payment processors, cash, customer and supplier balances, payroll, VAT, loans, and director or owner accounts where relevant.
