Attachments to the payment request are documents by which the beneficiary proves that an expense arose, was paid and is eligible. Their scope is set by the contract and the methodology, but the core is always similar: an invoice or other accounting document, proof of payment in the form of a bank statement, a purchase order or contract with the supplier, proof of delivery of the performance such as a handover protocol, delivery note or a list of work carried out confirmed by supervision, and procurement documentation. For wage expenses, timesheets and payroll records are added, and for training, attendance sheets. The most common reason for a payment being delayed is a request to supplement a missing document, so it is worth having a checklist before submission and completing the file on an ongoing basis, not retroactively before the deadline.
