What Is a Fixed-Price Contract?

A Fixed-Price Contract is a contract in which the buyer and seller agree on the total price of a piece of work or product that will be under production for an agreed-upon time. 

The buyer pays the seller at fixed intervals until the predetermined project is complete and all work has been completed to their satisfaction.

A Fixed-Price Contract consists of a Fixed-Price Agreement from the seller to the buyer, Fixed-Price Invoices from the seller to the buyer, and Fixed-Price Payment Terms from the buyer to the seller. 

Buyers can use Fixed-Price Contracts on simple or complex projects, while sellers usually use this type of agreement for tasks that have been done repeatedly before. Owners often use Fixed-Price Contracts on new buildings or renovation projects.

Advantages of Fixed-Price Contracts

A Fixed-Price Contract is useful when the buyer does not have an accurate idea of the scope of work involved in completing a project. 

  1. Fixed-Price Contracts protect both parties from unknown quantities and help reduce risk, by offering investors and buyers a predetermined price for the work.
  2. With Fixed-Price Contracts, both parties can plan effectively; sellers can predict revenue, while buyers can predict their final costs. 
  3. With Fixed-Price Contracts, both parties do not have to worry about losing money or canceling the contract if unforeseen events occur during the project. 
  4. Fixed-Price Contracts are easy to draw up, as the agreement is made between two parties who have agreed on a specific price for an item or service.

Disadvantages of Fixed-Price Contracts

Contractors often use Fixed-Price Contracts when they need quick and fast cash flow and do not want to wait for payments over time. 

  1. Contractors can use Fixed-Price Contracts on simple or complex projects, but Fixed-Price Contracts are only beneficial to the contractor if they know how much time and money a project will cost. 
  2. Fixed-Price Contracts can be more expensive for contractors than Hourly Agreements because Fixed-Price Contracts require a higher hourly rate from contractors. 
  3. Contractors can also lose money if the Fixed-Price Contract fails to account for hidden costs. When most Fixed-Price Contracts fail, it is because of unforeseeable problems that occur during the project. 
  4. The owner does not have control over how much time or resources are put into completing a Fixed-Price Contract with their contractor.Fixed-Price Contract Advantages and Disadvantages
