Managed billing & receivables for commercial subcontractors.
Commercial construction billing is its own discipline — pay applications, retainage, lien waivers, change orders, GC-specific requirements, and long payment cycles. Retainage Works manages that process.
The billing problem is consistent across every trade.
Commercial subcontractors operate in a billing environment that's more complex than most industries. Pay apps are due on GC schedules. Retainage can remain outstanding long after work is completed. Change orders need to be tracked and billed before they age out. Lien waiver and compliance requirements vary by project and GC. And outstanding receivables don't collect themselves.
Most subcontractors don't have the internal capacity to stay on top of all of it consistently. Work gets billed late, retainage goes untracked, change orders sit unbilled, and follow-up on outstanding payments doesn't happen with the frequency it should.
Retainage Works manages that function — the billing, the tracking, the follow-up, and the reporting — so contractors can stay focused on running and growing their businesses.

What we manage
Pay applications
Preparation, documentation, submission, and tracking on GC schedules across all active projects.
Retainage tracking
Retainage balances tracked from the first pay app through project close, with follow-up on outstanding releases.
Change-order billing
Approved change orders captured and incorporated into billing promptly.
Receivables follow-up
Consistent follow-up on outstanding pay apps and invoices, with documentation of every contact and status.
Lien waiver & compliance tracking
We track lien waiver and compliance document requirements across your projects — what's been requested, what's been prepared, and what's outstanding — and flag deadlines and exceptions. This is administrative tracking and support, not legal advice. Contractors should consult legal counsel on lien rights and filing requirements.
Why outsource billing and AR?
Building and managing an internal billing and AR function takes time, oversight, and consistent execution. For many commercial subcontractors, it's not the core business — but it directly affects cash flow.
Retainage Works manages the billing and AR function as a dedicated service. We handle the workflow, the follow-up, and the reporting — and keep you informed through regular updates.
If something requires your attention — a disputed billing, an unusual GC requirement, or a compliance issue — we flag it and work through it with you.
