Proof of completion
How do you prove work was completed?
Updated 15 June 2026
You prove work was completed by recording evidence at the point of work: a GPS-verified check-in, timestamped photos of the finished result, and a completed checklist signed off by the crew. Stored together as a visit record, this gives you an audit trail you can produce instantly when a client, auditor, or court asks.
Proving completion matters most exactly when it is hardest: weeks later, when memories have faded and the client is unhappy. Whether you clean, landscape, patrol, or maintain, the principle is identical. Capture verifiable evidence at the moment the work happens, and store it where you can retrieve it on demand.
The completion evidence stack
Tie the work to a time and place
A GPS check-in and check-out bracket the visit with location and timestamps, so there is no argument about whether someone was on site or how long they stayed.
Show the result, not just the attendance
Photos of the completed work prove the outcome. Attendance without a result is only half the proof; pair them.
Itemise what was done
A checklist breaks the job into contracted tasks and records each as complete, so completion is specific rather than a vague 'we finished'.
Keep a retrievable audit trail
Every visit is stored as a record you can search and export later. When a dispute or audit lands months on, you produce the evidence in seconds.
Frequently asked
What counts as proof that a job was done?
The strongest proof combines a GPS-verified check-in, timestamped photos of the completed work, and a signed-off checklist. Any one alone can be questioned; together they form a record that is hard to dispute.
How long should I keep proof-of-completion records?
Keep them for at least the life of the contract plus any dispute or audit window relevant to your industry. Software that stores visit history for the life of your account means you never have to decide what to throw away.
Is a signature enough to prove completion?
A signature confirms someone accepted the work but does not show what was done. Pairing a sign-off with photos and a GPS check-in is far more defensible.
Can I prove completion for past jobs I didn't document?
Only weakly, from memory and any photos you happened to take. The value of a proof-of-service system is that it documents every job going forward automatically, so you are never caught without evidence again.
