5-11.1 Billing Methods

Most contracts require suppliers to submit a proper invoice when goods and services are provided and received before payments are made. For contracts that do not require invoices, other methods may be used to ensure performance and payment. These methods include, but are not limited to, electronic authorization for payment, reviews of scan reports, and monitoring performance. In all cases, contracting officers must ensure (1) that controls are in place to ensure USPS receives the goods and services called for and (2) that USPS pays at the rate specified in the contract.

When using a method that does not require invoices and when the standard contract clauses are not included, contracting officers must ensure that these methods are efficient and effective and must coordinate with the Controller, Accounting, SOX Program Office, and SCM Strategies as applicable.
