Your back office runs while you run the job.
Contractor Operations Suite (COS) is the operations layer for a contracting business. Leads, schedule, pipeline, and invoicing stay in step on their own, so the office work stops piling up for after dark.
You finish the pour, then the second job starts. The one at the kitchen table. Leads that came in during the day still need a reply, the schedule needs updating, invoices need chasing, and the same numbers get typed into three different places. It is the work that slips first when the day runs long, and it is exactly the work that decides whether jobs get billed and leads turn into work.
How it works
The real job flow, start to finish. Five steps. The crew works the way they already work, and the office keeps up on its own.
01
Accepted
An estimate gets accepted in QuickBooks. COS pulls that job straight into the pipeline, so nothing has to be re-entered by hand.
02
Scheduled
You give the job a start date, and COS puts it on a color-coded calendar the crew already reads. Colors carry the status, so the field and the office are looking at the same thing, and COS keeps it synced from there.
03
In Progress
The crew advances the job right from the field. As they move it forward, the pipeline stays in step. No separate update, no double entry.
04
Done
When a job wraps, COS reads the billing state and surfaces what is ready to bill, so nothing finished sits forgotten.
05
Invoiced
A person reviews the invoice and hits send in QuickBooks. COS never sends it. It handles the busywork around that one human step, and it keeps the follow-up reminders going until the invoice is paid.
What it does
The pieces that keep the operation moving, without you steering each one.
Lead intake, every channel.
Calls, texts, emails, and web-form submissions come into one place instead of scattered across your phone.
One pipeline.
Every job in one view, from accepted to paid, so nothing falls between the cracks.
The crew calendar.
Color-coded so the field reads status at a glance, with a one-tap mobile view for updates from the job site.
Status that stays in sync.
QuickBooks, Google Calendar, and Google Chat all agree on where a job stands, without anyone re-keying it.
Invoice-chasing reminders.
COS keeps the follow-ups going on what is sent but unpaid, so you are not the one remembering to nudge.
Task lists that stay current.
Leads, estimates, scheduling, and invoicing each land on their own list in Google Tasks, so the follow-up work has a home instead of living in someone’s head.
A 24/7 self-audit.
COS watches its own work around the clock and flags what slips before it becomes a problem.
Weather alerts before a pour.
A heads-up lands in chat ahead of the pour, not after the rain.
What it runs on
COS runs on QuickBooks Online and Google Workspace today. That is where your books, calendar, chat, and files already live, so it fits the tools you already use.
It is built Claude-native, which means the core logic speaks in jobs, leads, and invoices rather than any one vendor’s plumbing. The integrations are connectors around that core, so COS is designed to extend to other systems over time.
You do not need a Claude account to use COS. Claude runs the intelligence underneath, on our side. QuickBooks and Google Workspace are the only accounts you need.
Who built it
COS was built by a contractor, not an engineer. With 25 years in contracting, he owned and operated a concrete polishing and epoxy company for 20 years with a good friend, then was brought on as operations lead for a concrete flatwork contractor in Northern Michigan. Soon after he started, he built COS to support that business.
He has no engineering background and no computer science degree. He built COS with Claude to solve that contractor’s back-office pain, using the 25 years of contracting experience he brought with him. It runs that real Michigan shop in production today.
COS opens to contractors in fall 2026.
If the office work is eating your evenings, get on the list. We are onboarding a first group of contractors this fall, and waitlist members hear first.
