Time-and-materials contracts are designed so the buyer pays for labor based on predefined hourly rates for each type of direct labor and reimburses actual materials at cost. This setup provides flexibility when the exact scope isn’t known, since both labor effort and material usage can vary and must be covered as incurred. The labor rates control how labor costs are calculated, while materials are charged at their true cost, rather than a fixed price. In contrast, a fixed-price contract sets a single price for the entire work, regardless of actual labor or material costs, shifting cost risk to the contractor. A cost-reimbursement contract covers allowable costs up to a limit plus a fee, which is not simply paying labor at hourly rates and materials at cost. An indefinite delivery contract governs how orders are placed over time but does not define a specific payment structure for labor and materials.
