What document should customers receive upon the completion of a contract?

Upon the completion of a contract, customers should receive a signed completion document or certificate of completion. This document serves as formal recognition that the contracted work has been finished according to the agreed-upon terms. It is important for both the contractor and the customer, as it provides proof of completion, which can be necessary for future references, warranty claims, or potential disputes over the job.

This document typically includes details such as the work completed, the date of completion, and any necessary signatures from both parties to confirm satisfaction with the work performed. Providing a certificate of completion also helps to establish a professional transaction, enhancing trust and accountability in the contractor-client relationship.

In contrast, while a detailed invoice is important for billing purposes, it does not signify the completion of work; it primarily serves as a charge for the services rendered. An estimate for future work is not relevant at the point of completion as it pertains to potential future services rather than current job fulfillment. A request for feedback, while valuable for the contractor's continuous improvement, is not an official document of the contract's completion. Thus, the signed completion document or certificate of completion stands out as the correct choice in ensuring that all parties acknowledge that the work has been satisfactorily completed.
