Work Completion Letters

Whenever a company outsources some task or project to another organization, they sign a contract. This contract specifies the term and conditions as well as a deadline when the project will be completed.

During the project, both companies communicate frequently about the project and its progress. Upon completion of the project, the contractor informs the principal company about the work completed. The principal company may inspect the project outcomes and release the final payment to the contractor. The contractor may write a work completion letter which is official proof that a project has ended.

This letter is important for both parties as it notifies the principal company that the work has ended. The principal company may then issue a work completion certificate to the contractor. These are important steps in a contract, absolving both parties of the terms of the contract and neither is liable to each other anymore.

Work completion letters are maintained in the files of the project along with other documentation regarding the project.

Work completion letters are mostly only issued when there are large contracts involved. You won’t find yourself signing a work completion letter upon getting the kitchen sink in your home fixed by a plumber.
