For a cleaning or pest-control business, the job is only half done when the team leaves the customer's home. The other half is paperwork: the invoice that matches what was promised, the card settlement that lands in the bank, and the reconciliation that proves the two agree. Businesses that neglect this half find themselves chasing money, arguing with customers about amounts, and struggling at tax time.

This guide explains the three pieces in plain terms and how they fit together in a service business with field teams, online bookings, and mixed payment methods.

The Invoice: What It Must Show

A GST invoice for a service job should show the business's details, the customer's details, the service delivered, the date of the job, the taxable value, the tax charged, and the total. It should also show the job reference that ties it to the booking, and the payment already received, if any, so the customer can see the balance clearly.

Accuracy matters more than speed. An invoice that charges for a service not delivered, or that omits a deposit already paid, will generate a complaint even if the job itself was excellent. The booking team and the field team must work from the same job sheet, so the invoice reflects what was actually done, including any agreed additions or reductions on site.

How Card Settlement Works

When a customer pays by card, the money does not land in the business's account instantly. The payment is authorised at the terminal or online, then settled through the acquirer, with fees deducted, and the net amount is credited to the business's bank account, usually after a short delay. The business should know its settlement cycle: which day's takings land on which day, and how weekends and holidays affect the timing.

Settlement delays create a cash-flow reality the business must plan for. A team paid weekly and suppliers paid on short credit cannot rely on card takings that have not yet settled. Tracking the settlement lag, rather than assuming takings equal bank balance, prevents awkward shortfalls.

Reconciliation: Matching Jobs, Payments, and Bank Credits

Reconciliation is the daily or weekly discipline of matching three records: jobs completed, card payments taken, and bank credits received. Each completed job should have a corresponding payment record, and each payment record should have a corresponding bank credit, net of fees. Gaps mean something went wrong: a job completed but unpaid, a payment taken but not settled, or a bank credit that does not match any job.

A practical routine is to reconcile daily for card takings and weekly for the bank. Daily, match the terminal totals and payment-link collections against completed jobs. Weekly, match the bank credits against the settlement reports, and query any missing or short credit promptly. Acquirers can resolve settlement queries, but only if the business raises them with specific transaction details, not with a general complaint that money is missing.

Handling Mixed Payments and Deposits

Service businesses rarely take only card payments. A single job may involve a deposit by payment link, a balance by card at the doorstep, and a small cash element. The invoice and the reconciliation must show all of them, so the customer is never charged twice and the business never loses track of a part-payment.

Deposits deserve special care. A deposit taken at booking should appear on the final invoice as a payment already received, reducing the balance due. A business that invoices the full amount and then separately chases the deposit will confuse the customer and create a duplicate-payment dispute.

GST, Records, and Tax Time

Clean invoicing makes tax compliance straightforward and messy invoicing makes it painful. Invoices issued, credit notes for refunds, and settlement reports showing fees deducted are all records the business needs for its returns. Keeping them organised by month, and reconciling them to the bank, means the accountant works from a complete set rather than reconstructing the year from scattered receipts.

Credit notes deserve the same discipline as invoices. When a refund is given, a credit note should be issued and linked to the original invoice, so the tax record matches the money actually retained. A refund without a credit note leaves the business accounting for tax on money it no longer holds.

Closing Thoughts

Invoices, settlement, and reconciliation are not back-office chores to be postponed. They are the system that turns completed jobs into collected revenue and clean tax records. A business that invoices accurately, understands its settlement cycle, and reconciles daily will collect more of what it earns, dispute less with customers, and face tax time with confidence. The paperwork is the proof that the work was done and paid for, and it deserves the same care as the job itself.
