Contractor project profitability: each project as its own profit centre
A contractor operating system that keeps cost control ahead of cash: budgets, commitments, subcontracts, change orders, billing and cash flow, per project.
Context
A multi-project contractor in Indonesia. Each project carries its own budget and has to show whether it is profitable and whether there is cash for payroll next week.
