How it works

Lines 4 to 9, from totals to date.

Retainage on a pay app is always worked out on everything billed so far, not on this month alone. That’s why one wrong total changes the payment due.

Questions

Retainage, answered.

Multiply work completed to date (columns D + E on the G703) by the retainage rate for line 5a, and stored materials (column F) by its rate for line 5b. Their total is line 5, the retainage held to date.
