Customers, contacts, templates and numbering are ready for the next job.
From the first agreement to the final invoice, see what was accepted and what comes next.
Choose a customer, add items and terms, then review the PDF before issuing.

Payments do not change agreed scope. An invoice discount does not reopen the same work for billing. You always review the invoice before issuing.
