Full route visibility

One-click invoice reports

All signatures, all locations, all workers

Proof of work

Not just an e-signature.
Proof they were there.

Most apps let anyone sign from anywhere, at any time. That's a digital form — not proof of work. Contract Keeper is fundamentally different.

Signatures are GPS-locked to the job site. If a subcontractor isn't physically at the location, the app won't let them collect the signature. No signing from the truck. No signing from home. No backdating.

You get the exact GPS coordinates, date, time, and who signed — with a direct map link attached to every record. When a commercial client disputes a charge, you can show precisely when their building was serviced and by whom, in seconds.

Signature GPS-locked to within metres of the job site
Timestamped at the moment of collection — can't be altered
Map link attached to every signed record
Stored securely in the cloud, accessible anywhere

Route management

Manage every stop
on your route.

A commercial window cleaning route can span dozens of buildings serviced by subcontractors you may not see in person for days. Contract Keeper gives you a live view of your entire operation — what's done, what hasn't been touched, and who's responsible for each stop.

Assign jobs to specific subcontractors, set locations, and track completion in real time. If a stop hasn't been checked off by midday, you know before your client does.

Every visit, every signature, every worker, across every account — all in one place. Whether you're reviewing before invoicing or fielding a client call on the road, the full picture is right there.

Billing & reporting

Invoice with confidence,
every time.

When you own the contracts but your subs do the work, invoicing has always carried risk. A client disputes a charge. A sub says they did the job. You're in the middle with no hard evidence.

Contract Keeper closes that gap. Every completed stop is automatically logged against the right client and location. When it's time to invoice, generate a full verified report across all your commercial accounts in a few clicks.

What used to take hours of chasing, cross-referencing, and guessing now takes minutes — with GPS-verified documentation attached to every line item.

One-click reports across all clients and locations
GPS-verified records attached to every job
Dispute resolution backed by hard evidence
Covers all subcontractors across all your accounts

How it works

Up and running in minutes

No training required. If your subcontractors can use a smartphone, they're ready on day one.

Add your locations and subcontractors

Set up your commercial accounts, map each building location, and invite your subcontractors. They get a login — you keep full control of what they can see and do.

Subcontractors collect the on-site signature

At the job site, your sub opens the app, completes the stop, and collects a GPS-locked signature from the client or building contact on the spot. Location is automatically verified by the app.

You get verified proof — instantly

The GPS-stamped record appears in your dashboard the moment it's collected. Track your full route in real time and generate invoice-ready reports whenever you need them.

Why Contract Keeper
