What type of invoices are prepared to request fixed payments related to fixed priced contracts?

When dealing with fixed-price contracts, the type of invoice that is commonly prepared to request fixed payments is an invoice. Invoices serve as formal requests for payment for goods or services rendered as outlined in the contract. In the context of fixed-price contracts, these invoices typically detail the agreed-upon amounts due based on the terms set in the contract, without needing to itemize costs in relation to actual expenses.

Invoices are essential for maintaining clear financial records and ensuring that payments are made according to the predetermined schedule specified in the contract. The use of invoices helps both the contractor and the client manage cash flow and set expectations for payment timelines.

Other options, such as receivables, pertain to amounts due from customers in a broader sense, rather than specifically indicating a request for payment. Payment vouchers often serve as internal documents to authorize payment rather than as a direct request for payment from a contract. Claims can refer to requests for additional payment or adjustments beyond what was originally agreed upon, often arising from disputes or unforeseen circumstances, not the routine fixed payments.
