3 ways to automate proof of attendance

#1 - Simple sign-off

Who it's for: Solo cleaners proving they showed up and completed the visit, and small firms that just need a signed record of who was on which site and when.

What it is: A GPS and time-stamped clock-in and clock-out, with a signature at clock-out confirming the scheduled tasks were completed. Four steps on a phone: pick whether this is a clock-in or a clock-out, tap to capture the location, type the site name, and at clock-out, sign to confirm the visit is done. Each completion is one stamped record, and the closing record of each visit carries all four: time, place, site name, and signature.

In practice: Take a solo office cleaning contractor with eight regular contracts across town. At the first site they open the canvas, pick "Clocking in", tap the location step, type "Maple Street office", and submit. Two hours later, on the way out, they fire it again at "Clocking out", tap a fresh location pin, type the site name, and sign to confirm the round is done. Eight sites in a day, sixteen stamped records, no paper timesheet and nothing to fill in back at home that evening.

Why it works: The location pin and the signature are the proof. The clean itself does not have to change. What changes is that there is now a server-side, time-stamped, GPS-tagged record at the start and end of every visit, and the closing record is signed to confirm the work was done. When a client questions whether anyone turned up on Tuesday, the answer is a pin on a map and a signature at a known time, not a memory or a hand-written timesheet that could have been filled in anywhere.

Steps included:

• 1 single-choice step (2 options: Clocking in, Clocking out)
• 1 location step (GPS capture)
• 1 text input (site name)
• 1 signature (end-of-shift sign-off)

#2 - With guidance

Who it's for: Multi-cleaner firms with staff spread across many sites who need everyone clocking in, out, and signing off the same way.

What it is: The signed clock-in plus two guidance panels woven through the canvas. The panels tell the cleaner when to clock in and out, and why the location is captured. A new starter on their first round gets the same instruction as a cleaner who has been on the contract for years, without a manager having to ride along and explain it, right up to the sign-off at the end.

What it adds to the simple sign-off:

1. A "when to clock in and out" panel that tells the cleaner to clock in on arrival and clock out on leaving, every single visit.
2. A "why we capture location" panel that explains the pin is what settles an attendance dispute, and that it saves offline and uploads when signal returns.
3. A consistent record across a whole team, because everyone reads the same instruction at the moment they clock in, before they sign off.

Why it works: Written guidance sits inline at the moment the cleaner is about to act. The cleaner reads the timing guidance the first time they clock in, and it is right there again at the next site. It is not a one-off induction talk they had weeks ago and half-remember. It is on the screen at the moment of the task, every time, right up to the signature that closes the visit.

Steps included:

• 1 guidance panel (when to clock in and out)
• 1 single-choice step (clocking in or out)
• 1 location step (GPS capture)
• 1 text input (site name)
• 1 guidance panel (why we capture location)
• 1 signature (end-of-shift sign-off)

#3 - With photo evidence

Who it's for: Clients who want visual confirmation of attendance, not just a signature and a coordinate on a map.

What it is: The signed clock-in plus an optional selfie taken at the same moment as the location pin. The cleaner takes a quick photo of themselves on site, and that photo lands in the same record as the pin, the time-stamp, and the sign-off. It confirms it was the cleaner who attended, not just their phone, alongside their own signature that the work was done.

In practice: Take a retail cleaning firm that services twenty high-street shops before they open. A cleaner arrives at a clothing store at 6am, picks "Clocking in", taps the location step, and takes a quick selfie inside the shutters they have just come through. Two hours later, clocking out, they take a fresh location pin and sign to confirm the round is finished. When the area manager runs the weekly check, they see a coordinate, a time, a face, and a signature, so there is no question that a real person walked the floor before the doors opened and signed to say the job was done.

What it adds to the simple sign-off:

1. A selfie step after the location step.
2. A second, independent confirmation that it was the cleaner on site, not just a phone in the right place.
3. Visual proof a client can glance at alongside the signature, which a signed record on its own does not give.

Why it works: A signature says the cleaner confirms the work was done. A selfie says a person was physically there. The two together answer the question a client actually asks, which is not "did someone sign this" but "did my cleaner turn up and do the job". Captured at the same moment, on the same device, the photo cannot be added after the fact to cover a missed visit.

Steps included:

• 1 single-choice step (clocking in or out)
• 1 location step (GPS capture)
• 1 text input (site name)
• 1 photo (quick selfie)
• 1 signature (end-of-shift sign-off)

How to pick the right version

You do not need to know how the canvas builder works to pick the right version. Every version signs off the visit; the questions below are about what you add on top.

Is it just you running this, or do other people run it too?

If it is just you, the simple sign-off (#1) is enough. You know when to clock in and out, you name your own sites the same way every time, and you do not need the canvas to coach you, only to record and sign the visit.

If anyone else uses it (a colleague, a new starter, a round of relief cleaners), go to #2. The guidance panels are what stop the clock-ins drifting and the site names going inconsistent across people. You write the guidance once and everyone reads it inline before they sign off.

Do you need a photo as proof, or is the signed record enough?

If your clients trust the coordinate, the time, and the signature, #1 or #2 is enough.

If a client wants to see that it was your cleaner who attended, and not just a phone in the right postcode with a signature against it, the signature alone is rarely enough. Go to #3. The selfie at the moment of the clock-in confirms a real person was on site, alongside the signature confirming the work was done.

Need both guidance and a photo? Open either version in the playground and add the other's steps. Every option here is the same signed clock-in with one thing added.

Conclusion

Proof of attendance is a GPS and time-stamped clock-in and clock-out, signed off at clock-out to confirm the scheduled tasks were done, so a client can see the cleaner was on site for the hours they paid for and that the work was completed. The photo-backed version settles a billing query in a minute instead of a week, because the closing record carries a time, a location, a signature, and a face all on one record.

Pick the version that matches how your contracts run today, not the most thorough one you can imagine running someday. Open each template in the playground above and try it on a real visit this week.
