Self-employed income records

Self-employed income records should explain what customers paid, what remains outstanding where relevant and why bank receipts differ from sales. Keep invoices, cash takings, platform statements and refunds connected to the accounting method used for the business.

Identify transfers, loans and money introduced by the owner separately. A payment processor may deduct fees before settlement, so the deposit alone can conceal both turnover and costs.

Follow a sale through the whole process

Choose a recent customer order and identify the agreement, invoice, payment and any refund. Record what the business supplied and when the relevant events occurred. If the customer paid in instalments, connect each receipt to the same underlying sale. A useful income record explains the commercial transaction rather than merely reproducing the sequence of bank credits.

HMRC requires appropriate business records and distinguishes the information needed under different accounting methods. ^[1] Confirm which method applies before deciding how unpaid invoices or advance receipts enter the calculation. Keep the underlying dates even where only one date drives the current tax treatment. They can still matter for customer queries, a change of method or a later reconciliation.

Capture cash and alternative payment channels

List every route customers use: bank transfer, cash, card reader, marketplace, payment link and any payment into an older personal account. Assign a simple record to each channel and reconcile it regularly. Cash spent directly on supplies must still be explained; it should not disappear from sales merely because it never reached the bank.

For a market stall, compare the opening cash float, takings, cash refunds, cash purchases and closing count. Investigate differences while the trading day is still fresh in memory. For a service business, connect payment links and deposits to the relevant client. These routines help distinguish an omitted sale from a timing difference without asking the owner to reconstruct several months of activity at the filing deadline.

Explain platform deductions and settlement delays

Obtain the detailed platform report behind each payout. Identify gross customer charges, fees, refunds, reserves and other adjustments, then reconcile the net amount to the bank. Keep a settlement identifier in the bookkeeping record so someone else can repeat the check. A single sales entry equal to the payout may conceal both income and legitimate cost information.

Check the report's date range and currency. Some platforms provide calendar-year statements that do not match the UK tax year or the business's accounting records. Use Tax records for online platform income for platform-specific reporting questions. Preserve the original export and document any conversion or period allocation rather than editing the report until its total happens to match the bank.

Keep non-sales credits identifiable

Money introduced by the proprietor, a loan, a transfer between accounts or proceeds from disposing of equipment may appear beside customer receipts. Label each movement from supporting evidence and flag uncertain treatment for the accountant. Do not assume every credit is turnover, or exclude an amount solely because the owner did not regard it as a normal sale.

Maintain a small suspense list for unexplained receipts with dates, amounts and next actions. Ask the relevant customer or payment provider for clarification where appropriate. Review the list before completing the accounts. Carrying an unidentified amount forward indefinitely can distort both the business result and the apparent customer balance, particularly when several people pay from accounts bearing different names.

Preserve a usable record when systems change

Export sales and customer balances before leaving a platform or replacing invoicing software. Test that attachments and transaction identifiers remain available, not just summary totals. Keep an index showing which system covers each period. If an old account must close, resolve how historic refunds or customer disputes will be investigated afterwards.

For Sole trader accounts preparation, supply the channel list, reconciliations and outstanding receipt queries. Agree how often records will be reviewed and who resolves differences. The related guide to Keeping records for a second business helps when more than one trading activity uses the same collection account. A clear separation at entry prevents unnecessary allocation work later and makes it easier to explain the performance of each activity without duplicating receipts or losing the evidence behind them.

After an error is corrected, retain the original reference and explain the adjustment. Avoid deleting a genuine transaction merely because it was allocated to the wrong customer. A traceable correction preserves the relationship between the commercial event, bank movement and final income figure, which is especially valuable when another bookkeeper takes over. Review recurring differences with the person operating the payment channel and correct the collection process when the same missing information appears repeatedly.

Illustrative scenario

A craft seller receives a weekly platform payout after fees and refunds. The seller reconciles the settlement statement to individual sales and records the fee separately instead of treating the payout as the complete sales history.
