One platform. AIA-grade pay-apps. 50-state lien rights. ACH straight to your bank.
Why subs choose Billitron
The construction industry is the worst-paying industry in the developed world.
Average DSO for construction subs is 80+ days. The rest of the economy averages 30. That gap is funded by your line of credit. Billitron is the platform that closes it.
Pay-apps that pass on the first review
AIA G702/G703 generated from your SOV with retainage, stored materials, change orders, and lien waivers attached. The PM can't kick it back over a formatting issue, because there isn't one.
Lien rights you don't lose by accident
Preliminary notice deadlines vary by state — 10 days in California, 30 in Texas, 90 in Florida. Billitron tracks every deadline, files the notice, and keeps your lien rights alive. Until the check clears.
ACH straight to your bank
When the GC approves the pay-app, ACH initiates automatically. 0.8% fee, capped at $5. No more waiting for a paper check to be cut, mailed, lost, and reissued.
A cash forecast you can show the bank
Every approved pay-app, expected ACH date, retainage release schedule, and pay-when-paid lag — modeled into a 13-week cash forecast you can take to your line of credit conversation.
Why Billitron exists
Subcontractors carry the construction industry's working capital. Nobody built them a platform for it.
The biggest software in construction is built for general contractors or for owners. Subs get the leftovers — generic invoicing tools that don't know what an AIA G702 is, or vertical PM suites that price you out at 10 users.
Walk into any subcontractor's office and you'll find the same setup: an Excel workbook for the pay-app, a folder of scanned PDFs for lien waivers, a generic accounting tool that doesn't understand retainage, and a controller who spends two full days a month chasing approvals.
The work is good. The collection is broken. Subs that should be growing their book spend their cash on a line of credit instead — paying interest on revenue that's already been earned but not yet paid.
Billitron is the platform that closes that gap. Built for the way subcontractors actually get paid: pay-apps, retainage, change orders, lien rights, ACH.

"I run a 22-person electrical shop. Billitron cut my pay-app turnaround from 14 days to 4. The lien tracker caught two preliminary notice deadlines my old system missed. That's not software — that's payroll."
