Keep four linked records
- A job or client record showing the scope and agreed price.
- An invoice register with issue date, due date and status.
- A receipt ledger showing when and how payment arrived.
- An expense ledger with purpose and supporting document.
Separate gross receipts from profit
Gross receipts show activity. Profit considers allowable business costs. Personal withdrawals are not a business cost, and a personal purchase does not become deductible simply because it was paid from a business account.
Make late payment visible
Track days from invoice to payment and the value overdue. A client that pays $5,000 after 120 days can create more cash-flow strain than a smaller client that pays on time.
Reconcile invoices, bank receipts, direct costs, unpaid work and the tax reserve. Save exported copies so the records are not dependent on one platform.
Use stable identifiers
Give each client and invoice a consistent code. Use that code in the invoice register, bank reconciliation, expense record and project folder. A payment reference that omits the invoice number can still be matched without guessing.
Reconcile the invoice lifecycle
| Status | Required field | Control |
|---|---|---|
| Draft | Scope and agreed price | Do not count as earned until work status supports it |
| Issued | Invoice date and due date | Lock invoice number and amount |
| Part-paid | Receipt amount and date | Keep remaining balance visible |
| Paid | Bank reference | Match total receipts to invoice |
| Written off | Reason and approval | Do not silently delete the invoice |
Document business purpose
For each expense, record what it was, why it was needed for the work, the amount, date and source document. If an item has mixed personal and business use, record the allocation method. A folder of receipts without business context is difficult to review later.
Track platform and foreign-currency differences
Record the client amount, platform fee, payment-processing fee, exchange rate or converted amount, and net cash received. This explains why the invoice and bank credit differ and provides a real measure of source profitability.
Close every month
- Match bank receipts to invoices.
- List overdue and partially paid invoices.
- Enter expenses and attach evidence.
- Calculate gross receipts, direct costs and net operating cash.
- Move the planned tax reserve.
- Export a backup outside the invoicing platform.
Prepare a reviewer-friendly year file
Create folders for sales, expenses, bank records, contracts and tax support. Add a summary that explains the business activity, accounting basis used, major income sources and unusual items. Accurate organisation does not decide tax treatment, but it makes professional advice and filing more efficient.
Control changes and credit notes
Never edit an issued invoice silently. Record the change through the appropriate corrected document or credit note and retain the original. The invoice register should explain why the amount due changed and how the client payment was allocated.
Keep client money distinct
A deposit for future work can create a cash balance before the related work is complete. Mark deposits and refunds separately from completed-project receipts. If the business collects money on behalf of someone else, do not treat the full collection as personal income without analysing the arrangement.
Back up for continuity
Export invoices, client contacts, expense records and attachments at least quarterly. Test that the export can be opened. A platform login failure near a filing deadline should not remove the only copy of the year's records.
Reconcile tax forms and third-party reports
If a platform, client or payment provider issues an annual statement, compare it with your invoice and receipt ledger. Differences can arise from fees, refunds, timing or gross-versus-net presentation. Keep the reconciliation and do not add the same income twice simply because it appears in two systems.
Run a monthly close that another person could reproduce
Begin with the invoice register, not the bank balance. Confirm each invoice number, client, issue date, due date, gross amount, tax treatment where relevant, status and receipt reference. Match bank receipts to invoices and leave part payments open with the remaining balance. A deposit without a reliable reference should be investigated rather than assigned to the nearest amount.
Next, review expenses. Record supplier, date, amount, business purpose, payment method and document location. Split personal and business portions with a note that explains the method. If a client reimburses a cost, link the expense and reimbursement so the same amount is not presented as both an unrecovered cost and additional profit.
| Monthly control | Evidence of completion |
|---|---|
| Invoice sequence | No unexplained duplicate or missing number |
| Receipts | Every deposit linked to an invoice, owner transfer or other explained source |
| Expenses | Document and business-purpose note attached |
| Credit notes and refunds | Original transaction remains visible and linked |
| Foreign currency | Original amount, conversion basis, fees and local cash received recorded |
| Backup | Export stored outside the invoicing platform |
Finish with a short close memo showing gross receipts, direct costs, operating expenses, unpaid invoices, tax reserve transferred and questions still open. Lock or version the period rather than silently editing it later. If a platform issues an annual statement, reconcile its gross-versus-net presentation, fees, refunds and timing to your ledger before using either total in a tax computation.
