4 ways to automate contractor sign-ins

#1 - The basic check-in

Who it's for: Single-site businesses with the occasional contractor, where someone different turns up to fix or service something every few weeks.

Available on: Basic.

What it is: A contractor sign-in is a short record taken the moment a visiting worker arrives, before they start on site. Four steps on a phone: type their name, type their company, type one line on what they are here to do, and pick roughly when they expect to finish. Each completion is one stamped record. The person on the desk runs it once per contractor, and the log for the day is the list of everyone who signed in.

In practice: Take a single-site garden centre. A refrigeration engineer arrives to service the chillers. The supervisor opens the canvas, types "Dan Whitfield", types "CoolChain Refrigeration", types "servicing the chillers in the plant room", and picks an expected finish of 2pm. Submitted. Server timestamp captured. When the engineer is still around at 4pm, the supervisor knows to check in, because the canvas said 2pm. One stamped record, on a phone, no clipboard by the back door.

Why it works: The sign-in is the record. The work the contractor does on site does not change. What changes is that there is now a time-stamped log of who was on site, who they work for, what they were doing, and when they should have been gone. If anything is damaged, missing, or left unsafe after they leave, the business has a name, a company, and a job description to start from, not a vague memory of "someone came about the chillers".

Steps included:

• 1 text input (contractor name)
• 1 text input (company)
• 1 text input (work being done today)
• 1 date and time input (expected finish time)

When to upgrade:

1. Add written guidance (#2) once contractors turn up often enough that briefing them properly by memory stops happening, so every contractor gets the same site rules.
2. Add photo evidence (#3) once you run more than one site and need to prove who was actually on each one, not just a typed name.
3. Add a signature (#4) once an auditor or an insurer could ask you to show that each contractor was briefed and confirmed it.

#2 - With written guidance

Who it's for: Sites with frequent or rotating contractors, where whoever is on the desk needs to brief them consistently without remembering every point.

Available on: Standard.

What it is: The basic sign-in plus two guidance panels woven through the canvas. A "site rules in 30 seconds" panel at the start walks the contractor through the fire exits, the assembly point, who to call in an emergency, and any areas to stay out of. A "what to do if something goes wrong" panel at the end makes sure they leave with a number to call. A weekend duty manager who has never met the contractor gives the same briefing as the site owner would.

In practice: Take a 40-unit self-storage facility open seven days a week. Contractors come and go constantly: a locksmith on Monday, a roofer on Wednesday, a pest-control visit on Friday. The team on the desk rotates, and not everyone knows the building cold. When the roofer signs in, the first panel prompts the desk staff to point out the fire exits and the one corridor that is off limits while a unit is being cleared. The roofer types their details, picks a finish time, and the last panel reminds them to call the duty manager if they find anything unexpected on the roof. The briefing stops depending on who happens to be working that day.

What it adds to the previous template:

1. A "site rules in 30 seconds" panel at the start that lists the fire exits, the assembly point, the emergency contact, and any no-go areas.
2. A "what to do if something goes wrong" panel at the end that tells the contractor to call the duty manager and makes sure they have a number before they start.
3. A consistent briefing that no longer depends on which member of the team is on the desk.

Why it works: Written guidance sits inline at the moment the sign-in happens. The desk staff read the site rules off the screen while the contractor is standing there, so nothing gets skipped because it was busy. The contractor reads the emergency panel the moment before they head off to work. It is not a laminated sheet on a wall that everyone walks past. It is on the screen at the moment of the sign-in.

Steps included:

• 1 guidance panel (site rules in 30 seconds)
• 1 text input (contractor name)
• 1 text input (company)
• 1 text input (work being done today)
• 1 date and time input (expected finish time)
• 1 guidance panel (what to do if something goes wrong)

When to upgrade: Move to Contractor Sign-in #3 once a typed name is not enough. Once you run more than one site, or someone could ask "can you prove the person who signed in is the person who did the work?", a name in a box starts to look thin without something to back it up.

#3 - With photo evidence

Who it's for: Multi-site businesses that want proof of who was actually on each site, not just a typed name in a log.

Available on: Standard.

What it is: The guided sign-in plus a photo step at the end. The contractor's ID, business card, or van gets photographed and lands in the same record as their typed details. A typed name can be anyone; a photo of a driver's licence or a sign-written van is something you can hold up later. Each sign-in now carries a visual confirmation alongside the written record.

In practice: Take a three-site letting agency managing blocks of flats across a city. Tradespeople attend all three buildings: a gas engineer at one, a fire-alarm tester at another, a window cleaner at the third. The building manager at each site runs the same canvas, types the contractor's details, and finishes by photographing the contractor's ID card or their sign-written van on the forecourt. Months later, when a tenant queries who entered the communal areas in March, the agency pulls the sign-in and sees the typed name next to a photo of the actual van that was parked outside. The record points at a real person, not just a name someone typed.

What it adds to the previous template:

1. A photo step at the end of the sign-in for the contractor's ID, business card, or vehicle.
2. A visual confirmation of who was on site, which a typed name on its own does not give.
3. A record that works across multiple sites, because every site captures the same photo evidence the same way.

Why it works: A typed name is a claim. A photo is something to check it against. The two together stand up to a query in a way that either alone does not. The name records who they said they were; the photo shows the ID or the van that was actually there. Captured at the moment of the sign-in, on the same device, the photo cannot be added after the fact.

Steps included:

• 1 guidance panel (site rules in 30 seconds)
• 1 text input (contractor name)
• 1 text input (company)
• 1 text input (work being done today)
• 1 date and time input (expected finish time)
• 1 guidance panel (what to do if something goes wrong)
• 1 photo step (contractor ID or vehicle)

When to upgrade: Move to Contractor Sign-in #4 once the sign-in is part of an audited or insured process that needs the contractor to confirm, in writing, that they were briefed.

#4 - With photo and signature

Who it's for: Audited sites that need a signed safety briefing on record for every contractor who sets foot on the premises.

Available on: Standard.

What it is: The photo-evidenced sign-in plus a contractor signature at the end. The contractor signs on the touchscreen to confirm they heard the safety briefing and understood it. That gives the record everything on one stamp: the time, the typed details, the photo, and a signed confirmation that the briefing actually happened. An auditor or an insurer would accept this as proof that the contractor was briefed before they started, captured in under a minute on a phone.

In practice: Take a food production plant that runs a tight audit regime, with engineers and cleaning contractors in and out around production runs. Every contractor who arrives is briefed at the door and signs the canvas before they go through to the floor. The signature is captured on the touchscreen, time-stamped, and attached to the same record as the photo of their ID. When the annual audit lands, the auditor asks for proof that contractors are briefed on the site rules. The plant manager pulls a month of sign-ins and shows a name, a photo, and a signature on every single one. The question is answered in minutes instead of a scramble through paper visitor books.

What it adds to the previous template:

1. A signature step at the end where the contractor signs to confirm they heard and understood the briefing.
2. A signed record on the same stamp as the time, the typed details, and the photo.
3. A defensible trail that shows not just that a contractor was on site, but that they were briefed and confirmed it before starting.

Why it works: The signature is what closes the loop. The typed details, the time, and the photo say a named contractor was here. The signature adds: and this contractor confirms they were briefed. Captured on the same device, at the same moment, in the same record, the four together are what an auditor or an insurer expects to see when they ask whether contractors are briefed before they start.

Steps included:

• 1 guidance panel (site rules in 30 seconds)
• 1 text input (contractor name)
• 1 text input (company)
• 1 text input (work being done today)
• 1 date and time input (expected finish time)
• 1 guidance panel (what to do if something goes wrong)
• 1 photo step (contractor ID or vehicle)
• 1 signature step (contractor sign-off)

When to upgrade: The next variations layer Poppi on top. A Poppi briefing that surfaces which contractors are due on site today. A Poppi gate that checks whether a contractor has signed in before letting a job start. A Poppi action that posts the day's sign-ins straight to the site manager's channel. Coming in the next post update.

How to pick the right version

You do not need to know how the canvas builder works to pick the right version. You only need to answer three questions about how your site runs.

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

If it is just you signing contractors in, the basic check-in (#1) is enough. You know the site rules, you know what to brief them on, and you do not need the canvas to coach you.

If anyone else runs it (a weekend duty manager, a rotating front desk, a new starter), go to #2 onwards. The guidance panels are what stops the briefing depending on who happens to be working that day. You write the site rules once; everyone reads them inline while the contractor is standing there.

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

If a query would be handled internally (you recognise your regulars, you trust the typed name), the typed record is enough. Go to #1 or #2.

If you run more than one site, or a tenant, an auditor, or an investigation could ask "can you prove who was actually here?", a typed name on its own is rarely enough. Go to #3. The photo of the ID or the van gives you something to check the name against.

Do you need someone to sign off at the end?

If the sign-in is operational and no auditor will ever look at it, the photo and the record are enough. Stick at #3.

If the sign-in is part of an audited or insured process, the signature is the lock. Go to #4. The signature closes the loop with a contractor confirming, in writing, that they were briefed before they started.

Conclusion

A contractor sign-in is a short, time-stamped record taken the moment a visiting worker arrives: who they are, who they work for, what they are doing, and when they expect to finish. The version an audited site runs adds a photo and a signature, so proving that every contractor was briefed before they started takes minutes instead of a hunt through a paper visitor book.

Pick the version that matches how your site runs today, not the most thorough one you can imagine running someday. Open each template in the playground above and try it on the next contractor who arrives.
