Pay for what's installed, not what's invoiced
The oldest leak in construction finance is approving a pay application for work that isn't done. BuilderStack ties billing to the same record the field writes: subcontractor pay apps draw their schedule of values from the contract, and approvers see reported progress — daily logs, quantities, photos — next to every line being billed.
Subcontractors submit pay apps through their portal on a standard form. No PDFs in inboxes, no version confusion, no billing ahead of the work without anyone noticing.
- SOV-based pay applications from the contract record
- Field progress visible on every billed line
- Standard submission portal for subcontractors
- Approval chain with audit trail and comments
Compliance and closeout, handled automatically
Retention math, stored materials, previous payments, and lien waivers are the details that turn a clean pay cycle into an accounting project. BuilderStack calculates retention per contract terms, tracks stored material separately, and collects conditional and unconditional lien waivers at the right stage of every payment.
Come closeout, the billing record is complete by construction — every pay app, waiver, and adjustment filed under the contract it belongs to.
- Automatic retention calculation per contract terms
- Conditional and unconditional lien waiver collection
- Stored materials and previous-payment tracking
- Complete billing record for closeout and audit
Frequently Asked Questions
What is construction invoice management software?
Invoice management software handles the billing side of construction — subcontractor pay applications, progress billing against a schedule of values, retention, lien waivers, and approval workflows. BuilderStack connects invoicing to field progress and the contract record, so payment matches verified work.
How do subcontractors submit pay applications?
Through a partner portal on a standard pay-app form drawn from their contract's schedule of values. Submissions route through your approval chain with the contract terms — retention, stored materials, prior payments — already applied.
Does it handle lien waivers?
Yes. Conditional waivers are collected with each pay application and unconditional waivers are required before funds release — tracked per payment, so no payment leaves without its paper.
Can approvers see field progress before approving?
That's the core difference — every billed line sits next to the daily logs, quantities, and photos that verify it. Approvers sign off on what the field documented, not what the invoice claims.
