Common problems
The client needs a purchase order
Do not invent one. Ask the authorised contact for the correct PO and billing address.
The invoice is disputed
Separate scope, price and completion evidence; respond in writing and issue a credit note rather than silently editing an issued invoice.
What to do next
Save a locked PDF, send it to the agreed billing contact and schedule a reminder before and after the due date.
