Procurement organizations frequently depend on contractual information that is distributed across tender records, negotiated documents, approval messages and operational systems. Digitizing those documents can improve access while leaving responsibility for obligations and changes unresolved. This paper develops an integrative framework explaining how digital contract lifecycle management can support procurement efficiency and contract compliance in Saudi Arabian organizations. A targeted review connects digital procurement, information systems, data governance, interorganizational contracting and legal language-processing research. The synthesis identifies five mechanisms: reliable contract data, controlled transitions between lifecycle stages, traceable links with procurement transactions, accountable monitoring of obligations and feedback from performance evidence. Three matrices translate these mechanisms into implementation requirements, indicators and validation activities. Two original conceptual diagrams distinguish system architecture from the proposed relationships requiring empirical testing. Efficiency is defined through comparable processing effort, waiting and rework; compliance is assessed through evidence against specified obligations and authorized procedures. The framework predicts conditional benefits rather than automatic improvements from software adoption. Organizational readiness, supplier participation, information quality and appropriate human review shape the proposed relationships. No survey, company audit or measured performance improvement is reported. The contribution is a practical explanation of how contractual text can become accountable operational information without confusing automated processing with verified fulfillment.
