THE PROBLEM
THE WORK IS DONE.
THE PAPERWORK ISN'T.
Commercial contractors don't need another dashboard. They need someone to own the details between completed work and an approval-ready billing package.

CHANGES GET
LOST IN THE SHUFFLE.
Extra work, field tickets and approvals end up in scattered texts, folders and spreadsheets.

WE OWN THE REPEATABLE ADMINREAL INDUSTRY PROBLEMS
THESE AREN'T
HYPOTHETICAL.
Project managers and subcontractors on Reddit describe the same billing problems we take off your plate.
PMs stuck doing billing and collections
A project manager describes preparing pay apps, handling billing and collections, and chasing sub paperwork on top of running projects.
One retainage error, weeks of waiting
A four-person commercial shop with five to seven active jobs rebuilds G702/G703 forms in Excel on Sundays. A retainage mismatch got a pay app rejected and pushed payment back about three weeks.
Extra work with no paperwork
A midsize electrical sub says foremen document extra work too late, so the office can't back up its change-order requests.
Retainage stuck for months
A subcontractor reports about $50,000 in retainage still held six months on, with no clear path to getting it released.

PROGRESS PAYMENT APPLICATIONS
Prepare monthly G702/G703 or other required pay applications from approved inputs, including SOV updates and prior billing reconciliation.
CHANGE-ORDER DOCUMENTATION
Collect approved scope and cost backup, organize field tickets and maintain a status register so changes don't disappear between field and office.
RETAINAGE & BILLING REGISTERS
Track withheld amounts, prior applications, outstanding items and monthly billing status in a format your team can actually use.

Organize required backup, identify missing records and track waiver status according to your contract and GC checklist.
DEADLINE & FOLLOW-UP COORDINATION
Keep the billing calendar visible, request missing items and flag issues before your cutoff dates.

Foremen text a photo of each signed T&M ticket. We log it within one business day and send your PM a weekly list of anything unsigned or unbilled.

One page each month: billed this period, retainage held by job, pending change orders and payments past due.

QUICK ANSWERS
STRAIGHT
ANSWERS.
Construction people are busy. Here's exactly how the arrangement works.
ASK US DIRECTLYWhere do you work?
New Jersey and New York City only. The work itself happens remotely, and because we're local we can meet in person when it helps.
Do we need to change our software?
No. We first confirm which tools and portals your team already uses, then scope work that can be performed with authorized access.
Who approves the payment application?
Your authorized team remains responsible for confirming work progress, financial amounts, final submissions, signatures and legal waivers. We prepare, review and coordinate documentation.
Can I just order one application?
Yes. A single pay app is $195. We confirm the project requirements before beginning; unusually complex work gets a separate quote.
What's in the free billing check?
Send one recent pay app with its SOV and change-order log. Within 48 hours we send a one-page list of errors, approved changes not yet billed, retainage you could request and missing waivers. No obligation.
How do the guarantees work?
If a GC rejects a package because of our error, we fix it free and refund that job's fee for the month. If you send your numbers by our intake date and we miss the GC cutoff, that job's month is free.
Can we send drawings and billing documents here?
Yes. Use Get started to send project details, and we'll share a secure upload link for files. Please submit only information you are authorized to share, and do not upload bank credentials, tax IDs or payment-card information.
Can you guarantee we'll be paid faster?
No. We can reduce avoidable paperwork issues and help manage timelines, but GC approval, contract terms, disputes and actual payment dates remain outside our control.
Is a long-term commitment required?
No. Monthly service is priced per active job and runs month to month. Add or drop jobs as they start and finish, and cancel any time before your next billing date.
