How finished work reaches you, and how to invoice it, chase it and correct it.

Finished jobs with charges on them wait in **Invoices → Ready to bill**. You don't need to ask the office what's done.

## Your routine

1. Open **Ready to bill**. Sort anything flagged, such as unpriced lines or a missing customer PO.
2. [Invoice the jobs](/invoices/invoice-a-job/), one or several for the same customer.
3. [Issue and email](/invoices/approve-and-send/) the invoices.
4. [Record payments](/invoices/record-a-payment/) as they arrive.
5. Check **Invoices → Overdue** and the **Aged debtors** report.

Mistakes on an issued invoice are put right with a [credit note](/invoices/credit-notes/). Issued invoices can't be edited, on purpose.

If your company keeps stock, [match supplier invoices](/stock/match-a-supplier-invoice/) to their purchase orders once the goods are in.

For contracts billed in instalments, Sustainable ERP drafts the invoice for you when each period starts. See [Contract billing](/contracts/contract-billing/).
