Nothing pays ahead of the waiver
Recording a payment on a bill missing its required waiver warns you on every US project — and blocks it outright when you turn the block on, overridable only with an audited reason.

Lien waivers collected, signed, and tracked before you pay
Collect conditional and unconditional lien waivers from the subs and suppliers you pay, get them signed in a no-login portal, and let Ledger warn — or block — a bill payment until the required waiver is in. California's statutory forms are built in.

One register per project tracks every conditional and unconditional lien waiver from the subs and suppliers you pay, tied to the pay application being paid and e-signed in a no-login portal — and BuildPass warns, or blocks, a bill payment until the required waiver is in. California’s statutory forms are built in.
Trusted by builders across the country
From custom-home builders to commercial head contractors, teams run their projects on BuildPass.
A payment shouldn't go out ahead of its waiver
The form, filled for you
California's four statutory forms are built in verbatim, every other US state gets a clearly-labelled generic form, and the amount and through-date default from the bill you're paying.
Signed without the back-and-forth
Send the payee's signatory a no-login link to review and sign, or upload a copy signed elsewhere. Either way it lands as received and the register updates itself.

Effective, not just signed
A conditional waiver counts only once payment clears; an unconditional one the moment it's received. Ledger shows the difference instead of assuming.
Connected to the whole job
Lien waivers sit right next to your bills
This is the money-out side of Win to Pay, built alongside bills. A progress waiver is created against the payee and the bill you're paying — which is where its amount and through-date come from — and when you go to record that payment, the bill's waiver coverage decides whether you get a clean pay, a warning, or a block. Because a conditional waiver's effectiveness depends on the payment actually clearing, the waiver and the payment stay tied together. Final waivers don't need a linked bill, so a supplier you pay without a subcontract is a first-class case.

Frequently asked questions
It's software for collecting the signed lien waivers a general contractor needs from the subs and suppliers it pays. In BuildPass you track every waiver in one register, generate the right form, get it signed in a no-login portal, and gate a bill payment on the waiver being in.
A conditional waiver takes effect only when payment clears; an unconditional waiver takes effect as soon as it's received. BuildPass tracks conditionality alongside stage (progress or final), so all four combinations are supported, and shows a conditional waiver as effective only once the linked bill's payment has cleared.
California's four statutory lien-waiver forms are built in word-for-word (Civil Code §§ 8132, 8134, 8136 and 8138). Every other US state gets a clearly-labelled generic waiver so you can keep moving, with a note to confirm the state-specific form with your counsel.
No. You send the payee's signatory a unique link to a no-login portal where they review the details and sign. The signed PDF is filed against the waiver and the status updates automatically. You can also upload a waiver signed outside BuildPass.
It always warns on US projects when a bill is missing its required waiver. Turn on the per-project block for a hard stop: BuildPass then won't record the payment until the waiver lands, unless you override it with a reason saved to the audit trail.
