Services sales invoices

Not every sale happens at the counter. A service billed after the job, an order taken by phone, a corporate customer invoiced at month end — these are entered by someone in the office, often after the fact, and sometimes need correcting. A services invoice takes stock out and posts to the ledger exactly as a register sale does, but lives on its own list with its own SRV numbering per branch, can carry an earlier date, and can be edited or cancelled under permission, with every change kept in the Activity Log.

1. Open Sales → Services Sales Invoices and press New invoice. Choose the customer — or leave it as a walk-in — the date, the branch and the warehouse the goods leave from.

2. Add the items. Each price fills in from the customer's price list and the stock in that warehouse shows beside it. Changing a price, or selling below cost, each needs its own permission.

3. Enter the payment against one method or several, using the same methods as the register, plus credit for a customer with a credit limit. Rest puts whatever is left on a method; the amounts must add up to the total.

4. Save. The invoice opens with its number, ready to print. It counts in every report and on the dashboard, but is listed only here, not under POS Invoices.

5. To correct one, open it from the list, change it and Save changes: stock is adjusted and the entry reversed and re-posted under the same number. Cancel invoice puts the stock back and reverses the entry; the invoice stays on the list marked Cancelled. Neither is possible once it has a return, a cash handover covers its date, or its period is closed.
