The project finishes, the client says thanks and the agency moves on. A month later, the next engagement repeats the same confusing approval process. End-of-engagement feedback should help you understand the client's experience and choose a service improvement. It is a different job from confirming deliverable acceptance or closing commercial obligations.

Ask for feedback without treating praise as proof that every part of delivery worked. A satisfied client can still identify something worth fixing.
Choose what you need to learn
Select a few parts of the experience: clarity of the brief, visibility of progress, usefulness of reviews and ease of reaching the right person. Ask about specific events rather than requesting a single score with no explanation.
Keep the conversation separate from requesting a testimonial. Permission to discuss feedback internally does not automatically authorise publishing the client's name or words. Obtain appropriate approval before any external use.
Use a short experience review
Try these questions:
At what point were you clear about what would happen next?
Which input or approval was harder than expected?
When did you have to repeat information?
Which update or review helped you make a decision?
What should we keep, and what should we change?
Invite examples and listen before explaining the agency's position. Confirm your understanding of the event and distinguish an observed experience from an assumed cause.
Compare feedback with delivery evidence
In an illustrative engagement, the client says progress felt uncertain even though every scheduled update was sent. Reviewing the messages shows that they listed completed activity without identifying the next approval or its owner.
The agency proposes adding one clear next-decision section. That is a testable service change. Sending more of the same updates would not necessarily address the client's difficulty.
Consider the people whose feedback is missing. One final sponsor conversation may not reflect the experience of the day-to-day client contact. Ask the appropriate participants without creating an excessive survey burden.
Close the learning loop
Record the observation, supporting example, proposed change, owner and the next suitable engagement where it will be checked. Keep identifiable feedback in an appropriate controlled location. Acknowledge what you learned to the client without promising an unapproved service change.
