The Costapp system

Cost planning, contract and subcontract control, and project records.

Traditional cost reports explain what happened. Costapp is designed to show what is likely to happen next, while retaining the official project record.

Use the same clear commercial controls across NEC and other or bespoke forms. Each contract and subcontract keeps its own parties, value, payments, correspondence, evidence and audit trail. NEC projects also include dedicated Early Warning and Compensation Event workflows.
