What does fix contract mean?

A fixed contract, often referred to as a fixed-price contract, is an agreement between parties where the price for goods or services is established in advance and does not change regardless of the costs incurred during the project. This type of contract provides budget certainty for the buyer and places the risk of cost overruns on the seller. Fixed contracts are commonly used in construction and project management, ensuring that the seller must efficiently manage their resources to meet project requirements within the agreed price.
