Some Types Of Commercial Contracts Are:
DEFINITE QUANTITY CONTRACT
A contract which provides for delivery of a definite quantity of specific supplies or services for a fixed period, with deliveries to be scheduled at designated locations upon order.
FIRM-FIXED-PRICE (FFP) CONTRACT
A fixed-price contract which provides for a price that is not subject to any adjustment on the basis of the contractor's cost experience in performing the contract. This contract type places upon the contractor maximum risk and full responsibility for all costs and resulting profit or loss. It provides maximum incentive for the contractor to control costs and perform efficiently and imposes a minimum administrative burden upon the contracting parties.
A contract type which provides for a firm price or, in appropriate cases, an adjustable price. Fixed-price contracts providing for an adjustable price may include a ceiling price, a target price (including target cost), or both. Unless otherwise specified in the contract, the ceiling price or target price is subject to adjustment only by operation of contract clauses providing for equitable adjustment or other revision of the contract price under stated circumstances.
TIME-AND-MATERIALS (T&M) CONTRACT
A contract which provides for acquiring supplies or services on the basis of (1) direct labor hours at specified fixed hourly rates that include wages, overhead, general and administrative expenses, and profit and (2) materials at cost, including, if appropriate, material handling costs as part of materials costs.
