A managed billing and receivables service for commercial subcontractors.
Retainage Works was built around a straightforward premise: commercial subcontractors shouldn't have to choose between running their business and staying on top of their billing.
What Retainage Works is.
Retainage Works is a managed service. We take on the billing and accounts receivable function for commercial subcontractors — pay app preparation and submission, retainage tracking, change-order billing, lien waiver and compliance document tracking, receivables follow-up, cash application, reconciliation, and reporting.
We're not a bookkeeping service, a staffing agency, or a software platform. We manage the workflow, oversight, and accountability around the billing and AR process, while keeping contractors informed through regular reporting.
We work exclusively with commercial subcontractors. That focus is intentional. Commercial construction billing has its own requirements — GC-specific pay app formats, retainage structures, lien waiver workflows, long payment cycles — and we're built around those requirements specifically.
What we're not.
We don't provide legal advice or legal services. Lien waiver and compliance tracking is administrative support — contractors should consult legal counsel on lien rights, filing deadlines, and statutory requirements.
We don't guarantee payment timing or collection outcomes. Payment depends on the GC, the owner, the contract, and the project. We manage the billing and follow-up process consistently and thoroughly — we don't control when a GC cuts a check.
Our focus is commercial subcontractors billing general contractors on commercial projects.
How we work.
We start by understanding your contracts, your projects, your GC relationships, and your current billing process. Onboarding is structured and straightforward — we're not asking you to change how you run your business, we're taking a specific function off your plate.
Once we're up and running, we manage pay apps against billing schedules, track retainage balances, incorporate approved change orders into billing, follow up on outstanding receivables, and provide regular reporting so you know where things stand.
If something is off — such as a disputed billing, an unusual GC requirement, or a compliance issue requiring additional attention — we flag it and work through it with you. We don't disappear when things get complicated.
