Entitlement to progress payments in projects depends on proving the execution of works in accordance with the contract and fulfilling all documentation and terms associated with invoicing and handovers. Consequently, an invoice or progress certificate is never viewed in isolation from remaining project documents; it is treated as part of an integrated chain that begins with a directive and concludes with proof of entitlement.
Evidentiary documentation includes the master contract, purchase orders, work orders, site handover protocols, blueprints, progress reports, minutes of meetings, inspection certificates, change orders, handover records, progress certificates, and exchanged correspondence.
Complications manifest when an invoice is detached from a document proving physical work execution, when the counterparty refuses handover or sign-off, or when records are scattered across departments without a centralized log. This delays collections or triggers disputes regarding the exact volume of executed works.
Legal consultations support reviewing project files, identifying documentary deficiencies, organizing procedures for performance and handover verification, and linking financial claims to their solid evidentiary foundations, thereby strengthening the file’s quality and backing the enterprise’s stance during negotiations or judicial claims.
