Monthly billing, end to end
The paperwork that has to be right, on time, every month, for every job. We take it off your plate.
Pay applications
AIA G702/G703-style applications built from your schedule of values and your PM's percent complete.
Change order billing
Approved change orders added to the right lines, so the work you've already done gets billed.
Lien waivers
Conditional and unconditional waivers prepared for each payment, matched to the right amounts and dates.
Certified payroll
Illinois prevailing wage certified payroll prepared from your payroll data on public jobs.
Retainage & payment follow-up
Retainage tracked job by job, and steady, professional follow-up when a payment runs late.
GC portal submissions
We submit through the portals your GCs use, including Textura, Procore and GCPay.

What changes for your business
Billing is how the work turns into cash. It deserves the same care as the work itself.
Get paid faster
Complete, on-time pay apps mean fewer reasons for a GC to hold your payment.
Fewer rejected pay apps
Every package is checked against the contract and the GC's requirements before it goes in.
Retainage that doesn't get forgotten
We track what's held on every job and follow up when it's due.
No extra hire
Get billing capacity without recruiting, training or covering for a new person.
You stay in control
You see and approve everything. Nothing is submitted without your sign-off.
We'll do one pay app for one job, free.
The best way to judge us is to see the work. Pick a job and we'll handle that month's pay app at no cost.
- One pay application, prepared and reviewed
- You approve it before anything is submitted
- No commitment after the pilot
Common questions
How do you handle security and access?
We only ask for the access we need to do your billing: contract documents, schedule of values, payroll data and GC portal logins. That access is used only for your billing, and you can change or revoke it at any time. We're happy to walk through exactly how we store and handle your information before you share anything.
Who approves what gets submitted?
You do. A person on our side reviews everything our software drafts, and then you approve the final package. Nothing goes to a GC without your sign-off.
Which GC portals do you work with?
We submit through Textura, Procore and GCPay. If your GC uses a different system or takes pay apps by email, let us know and we'll work with it.
What does it cost?
A custom monthly fee based on your job volume. Talk to us and we'll put together a number that fits. Your first pay app for one job is free.
What do you need from my team each month?
Mainly your PM's percent complete for each job, plus approved change orders and payroll for any prevailing wage jobs. We handle the rest.
Who do you work with?
Independent commercial electrical, mechanical, HVAC, plumbing and fire protection subcontractors in the Chicago area, including family-owned and employee-owned firms.
