Catch Waiver Problems Before The Check Goes Out

At Qvery, we help contractors spend less on paperwork, with custom AI agents that check lien waivers and product submittals. We build them around your own forms and checklists. This agent compares each waiver with the payment application it covers, one entry at a time. Your project accountant gets a clean pass or a note to the subcontractor, ready to send. Scans and phone photos of waivers work as they are. It checks that the signature and the notary stamp are on the page where your form needs them. A missing one is listed with its page. It checks presence, not whether they are genuine.

No. The agent compares the amount, the covered-through date and the type on every form. It also compares the names and the project against the payment application. Wherever the two differ, it shows both values together. Your project accountant reads the differences, not every form. A conditional waiver where you needed an unconditional one, or last month's amount, shows up the same way.

It reads both from the waiver and from the payment application it covers. It flags a waiver for a different amount, such as last month's figure. It flags a covered-through date that stops short of the period being paid, even by a week. It compares only the waiver and the pay application you sent, and nothing else. Your accountant sees each difference with both values beside it. It reads type, amount, dates, names and project from both documents, even on the subcontractor's own form.

Yes, when you give it the state form. It compares the waiver's wording with that form and shows where the language differs. Without a state form, it does not judge the wording. It never says a waiver is valid, enforceable or compliant. The legal reading stays with your team, and your lawyer joins where the case needs one. Your accountant sees both wordings where they differ.

No. It never says that a payment should be released or held. Releasing or holding the payment stays with your project accountant and, where needed, your lawyer. The agent gives your accountant the facts: a clean pass, or the differences with a note ready. Either way, your accountant decides from there. A missing signature or stamp goes on the note, and your accountant asks for a signed copy before paying.

Yes, in your build. It checks each lower-tier waiver against the payments it covers. It lists the ones still missing for a pay period, so your accountant knows who to chase before the check goes out. The same checks apply: type, amount, covered-through date, names, project, signature and notary stamp. The list of who is missing sits in one place. Your accountant sees at a glance which subcontractors have not yet sent theirs.

Building an agent for this job costs about $20,000. Running it costs about $450 a month. The calculator on this page lets you put in your own team's numbers. It shows what that means against your accounting team's time. The result updates as you type, so you see figures for your own team and not an average. Then you can weigh the build cost against the hours spent on waivers today. Both figures cover reading the waiver, comparing the entries and drafting the note.

The agent reads only the documents you send it. You decide where it runs and how long anything is kept. It contacts no subcontractor on its own, because the note is a draft. Subcontractors keep sending waivers on their own form or yours, and they see nothing from the agent. Your accountant reads every note before it goes out. Its findings describe the paperwork, and your accountant decides what to do with them.

We deliver a working agent in about two weeks, set up with your forms. It runs on a past pay period beside your accounting team first. They compare its findings with what they caught by hand. That shows you how it reads your subcontractors' waivers before anyone relies on it. After that, your accountant starts from the differences, even when a stack of waivers arrives in the same week. Your forms are loaded in those two weeks, so the first run already checks against your own.

You send one lien waiver and the pay application it covers. The sample page uses a contractor's progress waiver from a subcontractor with its payment application. You get the waiver checked against the payment, with both values shown wherever they differ. If something is off, you also get a note to the subcontractor, ready to edit. It comes from vlad@qvery.ai within 15 minutes. We delete your files as soon as the result is sent.
