Which type of contract involves a fixed price agreement?

A firm fixed pricing contract is characterized by a predetermined price that does not change throughout the duration of the contract. This type of contract provides both parties with a clear understanding of the costs involved from the outset, which can simplify budgeting and financial planning. The seller agrees to deliver the product or service at this fixed price, regardless of fluctuations in the cost of materials or labor during the project's execution. This arrangement reduces financial risk for the buyer, as the total cost is known and can help avoid potential disputes over pricing later in the process.

In contrast, other options involve varying degrees of uncertainty or flexibility. Time and Material contracts are dependent on the time spent and materials used, which means costs can fluctuate. A lease with an option to purchase typically involves payments over time, with the final price determined later. Open-ended contracts may not specify fixed costs and can leave both parties vulnerable to changing market conditions. Therefore, a firm fixed pricing contract distinctly stands out as the only option providing a guaranteed, stable price.
