For commercial subcontractors billing multiple GCs
Every GC wants a different billing format. You're rebuilding the same invoice from scratch each time.
BillBridge is for subs who lose hours each pay app cycle reformatting invoices for GCPay, Textura, custom spreadsheets, and proprietary portals.
Today
You've already got your invoice in QuickBooks or your own spreadsheet, but the GC needs it in their portal — a different line-item structure, their cost codes, their column order — so someone on your team spends half a day rebuilding it by hand, every single month, for every active GC.
With BillBridge
Your invoice data lives in one place. BillBridge handles the reformatting — GCPay, Textura, a custom Excel template, whatever the GC sent you — so your office isn't doing manual data entry across five different formats each billing cycle.
Conceptual — the workflow BillBridge is being built to handle.
What we keep seeing
This pain comes up consistently across subcontractor forums and trade finance communities: office staff describe spending significant time each billing cycle manually re-entering invoice line items into GC-owned portals and custom spreadsheets, with no reliable way to push data from their own accounting software directly into the format each GC requires.
Observed across public operator forums — the reason this page exists.
Without it
You've already got your invoice in QuickBooks or your own spreadsheet, but the GC needs it in their portal — a different line-item structure, their cost codes, their column order — so someone on your team spends half a day rebuilding it by hand, every single month, for every active GC.
With BillBridge
Your invoice data lives in one place. BillBridge handles the reformatting — GCPay, Textura, a custom Excel template, whatever the GC sent you — so your office isn't doing manual data entry across five different formats each billing cycle.
We're building format-conversion and portal-mapping logic specifically for the sub-to-GC billing workflow, so the rework stops at the source.
How BillBridge works
Bring your invoice
Connect your existing invoicing tool or paste your line items — BillBridge reads your SOV, cost codes, and amounts as you already have them.
Map each GC's format
Tell BillBridge which GC you're billing and upload their required template or portal spec — once per GC relationship, not once per pay app.
Export, upload, done
BillBridge outputs a correctly formatted file or fills the portal fields, so your submission is ready without a single cell of manual rework.
Straight answers
Can I use BillBridge today? +
We're building BillBridge now. Early users get first access, shape which GC portals and formats we support first, and will pay less than anyone who signs up later. If this is your exact problem, your input directly determines what ships.
What happens after I sign up? +
Within a few days you'll get a short email from the builder — a few questions about which GC portals and formats are burning the most time for your team. No newsletters, no drip sequences.
Who's behind BillBridge? +
An independent builder who's gone deep into the sub billing workflow — talking directly with project managers and office admins at subcontracting firms about exactly this problem. No VC-backed company, no sales team. Just someone building a focused tool.
We already use GCPay because our GC requires it — how does this help us? +
GCPay is the GC's system; you log into it because they make you. BillBridge sits on your side of that equation — it takes your data and formats it correctly for GCPay entry (or any other portal) so your team isn't manually transcribing line items from your books into their system every month.
