Proof of work
Proof of Work for Contractors: Free Report Template and Completed Example
A customer reviewing a completed job needs answers to four questions: What was requested? What was actually done? What evidence supports it? What remains open?
A proof-of-work report connects those answers to one job or visit. It brings together the agreed scope, field observations, photos, work details and a clear handoff.
Below is a free template organized around those questions, a completed fictional example, and six checks to run before delivery. No signup required.

What is proof of work for contractors?
Proof of work is a documented record of the activities and outcome reported for a specific job. It gives the customer or manager evidence they can review alongside the work summary.
Depending on the task, it can include:
- The work order and agreed scope.
- Before, during and after photos.
- Tasks actually performed.
- Materials and quantities used.
- Checks performed and recorded results.
- Exclusions, inaccessible areas and remaining work.
- The people who prepared, reviewed or acknowledged the report.
Someone who was not on site should be able to follow the record. Each photo, note and check needs enough context to explain what it relates to.
1. Start with the agreed scope
Record the work order, customer, site and exact area or asset.
“Interior entrance glazing at Building A” gives a reviewer a clearer reference than “windows.” For recurring visits, include a visit reference and date so records from different visits stay distinct.
Separate the requested work from the activities actually performed. If the technician finds an additional issue, document the observation and any authorization reference before describing additional work as approved.
Make exclusions visible. For example:
Scope: clean the lobby floor and accessible interior entrance glazing. Exclusions: storage room, exterior glazing and floor restoration.
That statement gives the reviewer a boundary for interpreting the work summary and photos.
2. Connect each photo to the job
Give every evidence item an ID tied to the job reference.
Use a sequence that adds useful information:
- Before: the visible starting condition.
- During: a relevant work stage or detail, especially something that will later be covered.
- After: the visible final condition from a comparable viewpoint.
A during photo is useful when it records something the reviewer needs to understand. It does not need to be included simply to fill a stage.
Caption each image with its stage, location and visible observation.
Weak caption:
Done.
Useful caption:
After: Building A entrance glazing, interior view. Smears shown on the lower panes in B02 are no longer visible in this view.
The second caption identifies a specific comparison.
If a before image is missing, record the gap and reason. Label the available photos with their actual stage.
For a matching-view method and reusable photo log, see the before and after photo report guide.
3. Record what photos cannot show
Photos do not explain every action, quantity or check. Add a written summary of:
- What was done and where.
- Which materials or parts were used.
- What was checked and how.
- What the check showed.
- What could not be checked.
Keep observations separate from conclusions.
A photo can show that a cover is in place. Whether the equipment operates needs its own recorded check.
An after photo of a floor shows its visible appearance. Any inspection or measurement should be documented separately, with its method and result.
Replace “all good” with the actual observation and its limits.
4. Document work you could not complete
An incomplete task needs a clear record too.
Where safe and permitted, photograph the obstacle: a locked door, blocked access or another visible condition that prevented the work. Give it an evidence ID and caption.
List the affected area under “Unverified or inaccessible items.” Identify the remaining action, owner and target date or scheduling condition.
Keep the relevant exception in the customer’s report. If it appears only in internal notes, the customer cannot see the boundary of the completion statement.
If the obstacle could not be photographed, record the observation and explain why no image is available.

5. State what acknowledgment means
Explain what the customer or site representative is acknowledging.
Possible meanings include:
- The visit took place.
- The report was received.
- The documented areas were reviewed.
- The completed work was accepted under the agreed process.
Use the wording that matches what actually happened.
If the customer was unavailable, record that acknowledgment was not obtained and identify the intended handoff route. Leave the customer acknowledgment fields unfilled until it is obtained.
Keep the technician’s own confirmation clearly identified as the technician’s record.
Completed proof-of-work report example
This example is fictional. The customer, people, references, evidence descriptions and quantities are invented to demonstrate the reporting structure. The quantities are not product-use instructions, and no real job photos are supplied.
What was requested
| Field | Entry |
|---|---|
| Job / visit reference | PW-0320 |
| Customer / site / work area | Example Property Services, Building A, lobby and main entrance |
| Visit date / technician | March 20, 2026 / Example Technician |
| Agreed scope | Scheduled cleaning of the lobby tile floor and accessible interior entrance glazing |
| Exclusions | Storage room, exterior glazing and floor restoration |
| Scope changes / authorization reference | None |
What was done
| Field | Entry |
|---|---|
| Tasks actually performed | Cleaned the accessible lobby floor and interior entrance glazing. The entrance corner behind a stored cabinet remained inaccessible |
| Materials / quantities / units | Floor-cleaning solution, 400 mL. Glass-cleaning solution, 250 mL |
| Checks performed / method / results | Visual review of accessible areas after cleaning. Scuff marks described in B01 were no longer visible in A01. Smears described in B02 were no longer visible in A02. The inaccessible corner was not checked |
What supports it
| ID | Stage | Caption |
|---|---|---|
| B01 | Before | Lobby floor, wide view from the reception doorway. Scuff marks visible near the entrance mat |
| B02 | Before | Entrance glazing, interior view from the lobby. Smears visible on the lower panes |
| B03 | Before | Entrance corner, view from the lobby. Stored cabinet blocking access to the floor behind it |
| None | During | No during photo recorded. No concealed work or intermediate detail needed documentation for this visit |
| A01 | After | Lobby floor, same viewpoint as B01. Previously recorded scuff marks no longer visible in this view |
| A02 | After | Entrance glazing, same viewpoint as B02. Previously recorded smears no longer visible on the lower panes |
Original evidence location: Job folder PW-0320, maintained under the company’s records process.
What remains open
| Field | Entry |
|---|---|
| Unverified or inaccessible items | Floor area behind the stored cabinet; obstacle recorded as B03 |
| Completion status | Scheduled work completed in accessible areas. One area remains open |
| Remaining work / owner / target date | Site manager to arrange access to the blocked corner before the next scheduled visit on April 3, 2026 |
Sign-off and delivery
| Field | Entry |
|---|---|
| Prepared by | Example Technician |
| Reviewed by / date | Example Service Coordinator / March 20, 2026 |
| Acknowledgment meaning | Receipt of the report and review of the listed areas. The blocked corner remains recorded as open |
| Acknowledged by / date | Example Site Representative / March 20, 2026 |
| Missing acknowledgment / reason | Not applicable; acknowledgment obtained |
| Report version / delivery date | Version 1 / March 20, 2026 |
| Intended recipient | Building A site manager |
The example connects each recorded visual result to a before/after pair. B03 supports the access limitation, and the remaining action has an owner and date. The completion statement stays limited to accessible areas.
Review before delivery: six checks
- Match the reference. Confirm every photo and attachment belongs to the correct job and visit.
- Compare scope and actions. Make sure the work summary describes what was actually performed.
- Check the evidence. Look for missing views, unclear captions and mismatched before/after pairs.
- Review quantities and results. Confirm units, asset references and recorded checks.
- Keep exceptions visible. Identify inaccessible areas and assign remaining actions to an owner.
- Check the shared copy. Review image readability, recipient details and information that should not be disclosed.
When correcting a delivered report, identify the revised version and explain the correction to the recipient. Keep earlier records according to your organization’s process.

Frequently asked questions
What should a proof-of-work report include?
The agreed scope and exclusions, actual work performed, materials and checks, captioned evidence, inaccessible or unverified items, remaining actions, and acknowledgment with a stated meaning.
Is a photo folder enough?
It can support the record, but the reviewer also needs context: job reference, scope, actions, captions, checks and exceptions.
What if there is no before photo?
Record that the starting condition was not photographed and explain why. Describe observations accurately and label available photos with their actual stage.
How do I show work I could not complete?
Document the obstacle where safe and permitted. Identify the affected area, remaining action, owner and target date or scheduling condition. Include the exception in the customer’s report.
What if the customer is unavailable to sign?
Record that acknowledgment was not obtained, identify the intended recipient and handoff route, and leave the acknowledgment fields unfilled.
Can the report include unfinished work?
Yes. State what was completed, what remains open and who owns the next action. Keep the completion statement consistent with those limits.
Is this report the same as an invoice?
The report records the job and its outcome. The invoice requests payment. Connect their references when useful.
Which report should you use?
| Your reporting need | Starting point |
|---|---|
| A customer handoff connecting scope, evidence and open items | The proof-of-work template in this guide |
| A fuller record of the technician’s visit | Field service report template |
| A photo log with matched before/after views | Before and after photo report guide |
Start with the agreed scope, connect evidence to the job, record the actual work and checks, and finish with a clear outcome that includes what remains open.
