To assist us in processing your payment(s) as quickly as possible, the following information constitutes a proper invoice for payment as required by the Prompt Payment Act (PPA) found at 5 CFR, Part 1315.9(b):
We process payments in accordance with the terms of the vendor's authorizing document. If the authorizing document does not state the terms, the PPA states that SSA has 30 days to pay, from the date the designated SSA office receives a proper invoice or the date SSA receives and accepts all the goods and services, whichever is later.
The preferred method of invoice submission is by email. Please refer to your authorizing document for additional invoice submission options.
