Cost plus contact

Explanation:

A cost-plus contract is a form of contract whereby the contractor is paid for all of its allowed expenses including additional payments in order to allow for a profit.

A cost plus contract is usually used when the quality, delivery time and performance is of more importance than the cost. In cost plus contract, the final cost may be smaller than the fixed cost because the contractors don't usually inflate price and also as a result of lesser price competition.

A cost price contract also gives more room for control and oversight over a contractors work and is also flexible which gives room for specification changes.
