How should government IT vendors operationalize monthly transactional data reporting to avoid payment delays?

For contracts that include the Transactional Data Reporting clause, the contractor must electronically report transactional data through GSA’s designated automated system or by uploading data under GSA instructions. The clause requires reporting within 30 calendar days after the last calendar day of each month, and it also requires a confirmation of no reportable transactional data when there is no contract activity. The contractor must keep reporting through physical completion of the last outstanding task or delivery order issued against the contract. GSA’s clause also requires the contractor to choose a consistent reporting point—either invoice issuance or receipt of payment—and to keep that method aligned with the contractor’s established commercial accounting practice. If the contract includes the Contract Access Fee, GSA’s written instructions control the remittance deadline, and failure to remit the full CAF can become a debt subject to withholding or offset of payments under FAR Subpart 32.6.
