| Question | Provvio, in its own words | LockProof |
|---|---|---|
| What the worker uses | “The office works from the web app; crews use the iOS and Android app.” | A text, WhatsApp or email link; tapping it opens the camera in the phone’s web browser. |
| How a visit begins | “Check-in stores the time and location against the site geofence.” | When the job is one you scheduled, its record already exists on the server before the worker taps the link. The server stamps the time the photo comes in. |
| How location is recorded | “When a crew member checks in, provvio records their coordinates and whether they were inside the site radius.” | The phone’s location, recorded on submission when the worker shares it. You can require a reading before a worker can submit. |
| Photos | “Before and after, each with its own timestamp” | A live photo through the camera, with the gallery blocked. |
| Check-out | “Time, location and time on site” | With Visit Mode on, a check-in photo and a check-out photo, each with a server-set time, and the time between them. |
| What the client receives | “A PDF report is emailed after check-out, or after approval.” “Each client gets a portal with their sites, visit history and reports.” | A proof link the client opens in a browser, valid for seven days. With the client portal on, a link to that client’s sites over the last 30 days. |
How does Provvio’s geofence check-in work?
Provvio answers this in its own FAQ: “Each site has a geofence. When a crew member checks in, provvio records their coordinates and whether they were inside the site radius. Check-out is recorded the same way, so the office can see where each visit started and finished.”
How does LockProof record where a photo was taken?
The phone’s location is recorded on submission when the worker shares it, and you can require a reading before a worker can submit. Distance from the site is an advisory flag: with the proximity feature switched on and the site’s location set, a photo that comes in from beyond a distance you set is flagged on your dashboard after it is saved.
What does a LockProof worker need on their phone?
A phone that opens links. The worker gets a text, a WhatsApp message or an email, and the link opens the camera in the phone’s browser. The link is what gets checked, so the worker installs nothing and signs up for nothing. That counts when the people doing the work are subcontractors or a vendor’s staff, on phones you never issued.
What does Provvio cost?
Provvio lists flat tiers by team size. Starter is US$29 a month for up to 3 team members, Crew is US$79 a month for up to 15, and Fleet is US$199 a month for unlimited team members, with a 14-day trial on the Crew plan and no card required, as of November 6, 2026.
Provvio’s US$29, US$79 and US$199 monthly figures are listed on its pricing page as of November 6, 2026.
What does LockProof cost?
LockProof is $9 per worker a month on Essentials, with a $49 monthly minimum, and $17 per worker a month on Professional, with a $99 monthly minimum. A worker is a person who receives checks. Manager and office logins are free. There is no limit on sites on any plan.
The plans are on the pricing page.
Who is Provvio built for?
On its homepage Provvio calls itself “Proof of service software for cleaning, grounds and security crews”, and its footer reads “Proof-of-service platform for recurring service businesses.” If you want your crews working in a phone app, with a geofence check-in, a checklist with photos, and a PDF report emailed to the client after check-out, that is the product its own pages describe, with a trial you can start without a card.
Who is LockProof built for?
LockProof is field work verification software for property managers, home care agencies and field service teams, for operators who want the request to come from the office. The schedule sends each check at a fixed time, or at a random time inside the hours you set, and the worker answers it with a live photo. If a check’s window closes with no photo, the manager on record gets an email. It suits work done by a crew, a subcontractor or a vendor, for a client who may one day ask to see the record of each visit.
What a LockProof record holds
Every LockProof record carries a SHA-256 fingerprint over the image and the server-set time, plus the coordinates when the worker shares location, so a later change to the record is detectable. The Evidence Vault gathers the records for one site, or all of them, over the dates you pick into a dossier you can print, save as a PDF or export as a CSV. Dispute packets go out as an expiring, revocable share link, on Professional and up.
Invoices for work that was not done
In September 2026, the general manager of a 924-unit housing cooperative in Bridgeport and Stratford, Connecticut, and a part-owner of one of its plumbing and heating contractors each pleaded guilty in federal court to conspiracy to commit wire fraud. According to the U.S. Attorney’s announcement, published by IRS Criminal Investigation, vendors billed the co-op for work that was not performed or at inflated prices, then passed about 10 to 30 percent of what they were paid back to the manager and an associate. More than $526,000 of the plumbing contractor’s payments was diverted that way. Both men await sentencing.
The person approving the invoices was taking a cut of them, so nothing on the paying side stood apart from the bill. A record of each visit kept in the owner’s own account, with a live photo and a time the server sets when it is submitted, is something a board can hold an invoice up against before it pays. It makes the question easier to ask early; it settles nothing on its own.
Where a photo record stops
A sealed record shows that the photo came through the live camera with the gallery blocked, and the time the server received it, and a later change to the record is detectable. The quality of the work is a judgment for a person, and so is matching the room in the picture to the room on the contract.

Read the transcript
Opening 0:00
Did the job get done? Today, the answer is a phone call, or a photo somewhere in a group chat. LockProof gives you a record instead.
Schedule 0:11
You set it up once: who, where, and when. LockProof texts the link on the schedule you set.
Camera 0:19
The link opens the camera, not the photo library. It runs in the phone’s browser, with no app and no login.
Seal 0:29
The record is sealed when it arrives. Our server sets the time, and a SHA-256 fingerprint covers the record, so a later edit would no longer match it. The location comes from the worker’s phone when they share it, and you can require it before they can submit.
Dashboard 0:49
One screen answers the morning question. The rate is compliant visits out of every check sent, misses included. Excused checks are left out. A miss comes to you. When a scheduled check passes its window with no photo, LockProof emails the manager on record.
Proof link 1:10
When a client asks, send the proof link. Anyone can open it in a browser, without an account, for seven days. It is a record of what was sent, not a certificate for the work. LockProof. Know the work got done, without calling anyone. See it for your own team at lockproof.com.
