On a construction job, the paperwork runs on a monthly cycle: every subcontractor submits a pay application, every payment needs a lien waiver, and the general contractor collects the same document from a dozen different companies with only the names and amounts changing. It is one of the most repetitive document workflows in any industry, and it is almost always done by editing last month's file and hoping nothing was missed.
Lien waivers, subcontractor agreements, and W-9s repeat the same job, owner, and company details every payment cycle. Saving each subcontractor as a reusable profile fills those fields automatically, so only the amount and period change month to month. Filly AI fills and sends these forms for signature through a link that needs no account.
Why do lien waivers take so much time when the form is so short?
Because there are four of them, and they are not interchangeable. Most states distinguish between conditional and unconditional waivers, and between progress payments and final payment — four combinations, each with different legal effect. California, for example, prescribes the exact wording of all four statutory forms in Civil Code § 8132 and the sections following it, and a waiver that departs from the prescribed language may not do what the signer expects. So each month, the right variant has to be picked, then re-typed with the correct job, owner, property, through-date, and amount.
The identifying details — legal company name, license number, address, property description — never change. Only the period and amount do. That ratio is exactly what makes the task worth automating rather than delegating.
Which details repeat across every construction form?
Across a typical subcontractor's file you will find the same handful of values on a lien waiver, a contractor agreement, a statement of work, an insurance certificate request, and a Form W-9: legal entity name, DBA, address, contact, EIN, license number, and the job or project identifier. Entered once as a saved profile, they populate all of those documents. What's left to type each cycle is the part that genuinely varies.
How do I collect signed waivers from a dozen subs without chasing them?
The bottleneck is rarely filling the form — it is the round trip. Emailing a blank PDF means the sub prints it, signs it, photographs it, and sends back something crooked and unreadable, often with a field left empty. Sending a prefilled document as a share link inverts that: everything you already know is on the page, the sub completes only what's theirs, signs on a phone, and the finished PDF returns to you complete. No account, no app, no printer on a job site.
For the general contractor collecting from many subs at once, a batch fill applies the same waiver across multiple saved profiles in one run — five per batch on the $19/month Solo plan, twenty on Pro.
What should be double-checked before a waiver is signed?
Three fields cause most of the disputes: the through date (a waiver covering work beyond what has actually been paid for gives away more than intended), the amount, and conditional versus unconditional — an unconditional waiver takes effect whether or not the payment clears. Also confirm the legal entity name matches the one on the contract and the license, not the trading name people use on site. This is general information about document workflow, not legal advice; construction lien law is state-specific and worth reviewing with a construction attorney.
Does this work for the rest of the job file too?
Yes, and that is where the compounding is. Change orders, safety acknowledgements, certificates of insurance requests, and closeout documents all draw on the same profile data. The pattern is identical to the one described in filling contracts online free — the document changes, the underlying party details don't.
Frequently asked questions
Can I use my own company's waiver template rather than a generic one?
Yes. Upload your existing PDF or Word document and it becomes a reusable form — including flat PDFs with no fillable fields, where answers are placed onto the page.
Do subcontractors need an account to sign?
No. A share link opens in any browser, and the signer completes and signs their part without registering.
Can I fill the same waiver for every sub on a job at once?
Batch fill applies one form across multiple saved profiles in a single run. It is available on paid plans — up to 5 profiles per batch on Solo, up to 20 on Pro.
Are lien waiver requirements the same in every state?
No. Several states prescribe statutory wording and others leave the form open, and deadlines differ widely. Use your state's required form and confirm the specifics with a construction attorney.
What does this cost to try?
The free plan covers 10 forms, 5 clients, and 10 fills a month with no credit card, plus a first e-sign share at no cost. Paid plans start at $19/month.
