Start with the acceptance decision.
For each task, ask what the buyer must be able to confirm. An installed device may need a location photo, a readable equipment identifier and a relevant test result. The right evidence depends on the scope.
Name each required item.
Use direct instructions such as “one overview of the installed equipment” and “one readable image of the asset label.” Specify file types or measurements when they matter. Avoid collecting unrelated documents.
Check evidence while still on site.
Review framing, lighting and readability before leaving. Confirm that the required labels are legible and files open. A photo of an illuminated device does not, by itself, prove that the service works.
Keep customer information out of the frame.
Avoid capturing passwords, personal information, private screens or unrelated customer records. Arrange the shot to show the work with the least unnecessary information.
Preserve the correction trail.
If evidence needs to be replaced, keep the earlier submission associated with the review history. Explain what changed and why, so the technician and buyer can follow the same sequence.
Separate evidence from approval.
A submitted checklist is ready for review; it is not automatically an acceptance decision or confirmation of a bank payout. Keep those steps clear in your operating process.
