Checklist · Workforce and proof of work
What should field service proof of work include?
Proof should answer who attended, where and when, what they were asked to do, what happened and what remains open.

The short answer
Field service proof of work should include the job and site identity, assigned worker, service time, completed scope, outcome notes and the evidence appropriate to the service—such as photos, readings, forms or acknowledgement. It should also name exceptions and follow-up rather than presenting partial work as complete.
More evidence is not always better
Collect only what helps verify scope, quality, safety or customer acceptance. Unlabelled photo piles create storage and review work without making the service easier to prove.
Evidence needs context
A photo or signature should identify the job, date and purpose. Context turns an attachment into usable evidence during invoice review, complaint handling or renewal.
A practical process
- Define required evidence by service, site or contract.
- Capture identity, time, outcome and supporting attachments.
- Review missing or contradictory evidence before approval.
- Keep accepted proof linked to the job and invoice history.

Questions about what should field service proof of work include?
Are before-and-after photos always enough?
No. They may show visible change but not readings, hidden work, customer instructions or unresolved risk. Use the evidence that fits the service.
Should every job require a signature?
Only when the contract or operating process needs acknowledgement. Avoid collecting signatures that do not prove a meaningful decision or outcome.
Who reviews proof of work?
Routine work may close automatically after required fields are present; higher-risk, disputed or contract-sensitive work may need supervisor or customer review.
