Learn how to properly report your contract performance through comprehensive documentation and interagency agreements.
The OASIS contract requires vendors to properly report new task orders awarded against their contract in the Contract Payment Reporting Module.
Failure to ensure the CAF is appropriately included in all task order solicitation responses and subsequent task order awards, on a separate line item, may lead to contract non-compliance. It is critical to ensure CAF is paid to you by ordering contracting offices, so that you may in turn remit payment to GSA.
Your OASIS contract requires you to report new task orders awarded against your contract within 30 days in CPRM, and to report invoices each quarter after that. Remittance of CAF billed to, and collected from, your customers in a timely manner through CPRM reporting is required by the contract in Section G.3.1., Contract Access Fee.
You may contact oasiscprm@gsa.gov with any questions you have about CPRM or reporting.

Unless otherwise specified, the per diem locality is defined as "all locations within, or entirely surrounded by, the corporate limits of the key city, including independent entities located within those boundaries."
Per diem localities with county definitions shall include"all locations within, or entirely surrounded by, the corporate limits of the key city as well as the boundaries of the listed counties, including independent entities located within the boundaries of the key city and the listed counties (unless otherwise listed separately)."
When a military installation or Government - related facility(whether or not specifically named) is located partially within more than one city or county boundary, the applicable per diem rate for the entire installation or facility is the higher of the rates which apply to the cities and / or counties, even though part(s) of such activities may be located outside the defined per diem locality.
