Quality assurance for the IT services you buy.

You pay your outsourcing and staff-augmentation vendors for people and hours. WorkProof checks every billed hour against the work in your own Git, Jira and timesheets, and shows you where the two don’t match.

Nothing to install. No access to anyone’s laptop.

What WorkProof checks today

Every check compares what a vendor billed with evidence in systems you already own. Each finding names the person, the hours and the records behind it.

Billed, but not working

Someone is on every invoice but leaves no trace in your systems: no commits, no tickets, no reviews. Some left the team months ago. Some never joined it.

Billed while away

Output stops for two weeks, but the bill doesn’t. The gap is PTO, another project or a second job, billed as work. Each billed day is matched against activity in every system you connect.

Someone who just graduated, billed as a senior. WorkProof checks each billed person’s public professional profile against the level and rate in your contract.

Remote work and AI made this easier to hide

Fake candidates, proxy interviews and people holding several jobs at once are now common. Most companies check identity at hiring and stop there.

How it works

WorkProof reads the systems you already use. Your vendor doesn’t need to install, approve or change anything.

  1. Connect

    Give read-only access to your Git host, Jira or Azure DevOps, and your time tracker: SAP Fieldglass or an in-house tool. Add the roles and rates from your vendor contracts.

  2. Reconcile

    WorkProof lines up every billed hour with the commits, tickets and reviews behind it, per person and per day, and checks each person’s public profile against the level billed.

  3. Review

    Each finding comes with its evidence, ready to take to the vendor.

Check what you’ve already paid for

A look-back audit runs over months of history from a vendor you already use. Useful before a renewal, a rate negotiation or a vendor switch.

Watch projects as they run

Findings arrive while the sprint is still open, so you can fix the team or the invoice before you pay it.

No spyware. Nothing installed.

WorkProof never touches a laptop, a screen or a camera. It reads work records your company already owns, so there’s nothing for your vendor’s staff to install or switch off.

What we read

  • Commits, pull requests and code reviews
  • Tickets and their history
  • Billed hours and approved timesheets
  • Roles and rates from your vendor contracts
  • Public professional profiles, to check experience against the level billed

What we never use

  • Screenshots or screen recordings
  • Keystrokes or mouse activity
  • Webcams or microphones
  • Software installed on anyone’s device

Commits and tickets still name people. We’ll walk your data protection officer or works council through exactly what is read and why.

Found overbilling? Get the money back.

Pro-services turns findings into a claim your vendor has to answer, so a finding becomes a credit, a refund or a better contract.

  • An evidence pack for each finding

    The billed hours, the records behind them and what the contract says, in one document.

  • A review of your contract terms

    What you can claim, from whom, and over which period.

  • Legal support when a dispute needs it

    Through our partner law firm, when a vendor won’t settle.

Built by people who’ve been on both sides of the contract

We’ve worked inside the vendors that supply engineers and inside the companies that buy them: more than 1,000 outsourcing companies and 100 engineering teams, including on the receiving end at a Big 4 audit firm.

We’ve built and sold businesses of our own, and spent more than $1M on IT services ourselves. We’ve seen every way a bill drifts away from the work, and we’ve dealt with the billing disputes that follow.

No company is too small or too big to be overbilled

At a large enterprise it’s even easier to hide. Contractors arrive through many vendors under separate contracts, and each invoice checks out on its own. Someone billed for months of no work disappears in the crowd unless every billed person is checked against the work.

Questions buyers ask

Can’t a vendor just fake activity?

Padding one system is easy. Keeping commits, tickets, reviews and timesheets consistent with each other, every day and for every person, is not. WorkProof also looks at what the work is, not only how much of it there is.

What about people who don’t write code?

Project managers, analysts, testers and architects leave different traces, such as tickets, comments and reviews. The roles you define set what normal work looks like for each of them.

Will this hurt our relationship with the vendor?

Findings are evidence, not accusations. You decide what to raise and when. An honest vendor has nothing to lose from a clean record.

What access do you need?

Read-only access to your Git host, Jira or Azure DevOps, and your time tracker, plus the roles and rates from your contracts. Nothing connects to your vendor’s systems or devices.

Can you check work done before we sign up?

Yes. A look-back audit runs over the history that’s already in your systems.

Does our code go to AI models?

WorkProof uses leading AI models to read commits and tickets in context. Ask us how data is handled for your setup. On-premises analysis, for code that can’t leave your network, is coming soon.

Which time trackers do you support?

SAP Fieldglass and in-house time trackers. Tell us what you use when you request access.
