Myself and customer agreed on a support period after delivery, for the application testing is done and for reports also is done, but this test performed with demo data not actual live data (Application is Time Attendance system which need to be configured as customer's clients) so how to tell the customer nicely that any issue in UAT is within the report delivery and after fixing issues captured in UAT is support.
I'm asking this becasue I've a payment after deliver the reports itself, so how to declare the issues captured in UAT and issues captured after UAT.
