Financial operations for custom home builders
We turn financial chaos into a system you can trust.
This is not bookkeeping. We rebuild the entire back office of your building company. Admin, financials, and project coordination connected into one system, on an AI architecture built to know your business, installed hands-on with your team.
What you're looking at
Your entire back office, rebuilt as one system.
Most building companies run three disconnected worlds. The admin side, the books, and the project side each doing their own thing, with information re-typed, dropped, and chased between them. Fixing one of them never fixes the chaos, because the chaos lives in the handoffs.
BuiltOS by Catalyst CAC connects all three. One operating system for the whole back office, custom-built around how your company actually runs, with an AI architecture underneath that learns your business as the system goes up. We install it hands-on, deep in the details of your workflows, and we train your people until they run it with confidence.
Administrative operations
The documents, the inbox, the schedule, the paper trail. The infrastructure everything else reads from.
Financial operations
Job costing, draws, committed costs, change orders, the monthly close. The spearhead of the whole system.
Project coordination
Where the field meets the office. Budgets, selections, and schedules that stay connected to the money.
And the seams between them get built on purpose, which is exactly where every other fix falls apart.
The way out
A build, not a subscription.
BuiltOS is a done-with-you build. We are in your business, elbow to elbow with your team, deep in the nooks and crannies of how your office actually runs, until the system is up, the workflows hold, and your people run it like they built it. Because they did.
Inspect
We start with your own numbers and show you exactly what is broken. Evidence, not a pitch.
Build together
Hands-on, workflow by workflow, with your team in the room the whole way. Your business's own AI brain gets built right alongside the system.
Equip your team
Training, SOPs, and real reps until your people own it with confidence. We build them up, not around them.
In your corner
The system becomes yours, and support never goes out of reach. Advisory, community, and a team that already knows your business, there when you want us.
The build has a finish line, and we put a name on it: The Final CO. Getting your team there strong is the whole point.
See how BuiltOS worksWhy you can trust it
Three reasons the system holds.
Built for your business, run by your team.
One connected system across admin, finance, and project coordination, shaped to how you actually work and run by your own people, because we build it with them, not around them.
We've been in your chaos.
Cost codes, draws, committed costs, the 2 a.m. version of the problem. We did not read about builder chaos. We came out of it, and we built this firm because nobody was fixing it right.
CFO-grade output, and it's yours to keep.
The reporting a builder used to rent a CFO to get, produced inside your own business by an AI built to know it. Not a login you rent. A capability you own.
The part nobody else is building
Just having AI won't set your business apart. An AI built to know your business will.
Everyone is talking about what AI can do. Almost nobody is talking about how to get it to do that well inside a construction company. Used one chat at a time, AI is a smarter Google. It forgets your business the moment you close the tab.
We build it the other way. Trained on your jobs, your cost codes, your workflows, your history, it becomes a financial brain your company owns. That is what gets installed alongside the system, and it keeps evolving as the technology does, so your company moves first, not last.

Two ways in. Pick yours.
Get the whole system built.
The books are behind, the margins are a guess, and the office is held together with workarounds. Start with the Inspection. Your own numbers, not our opinion, and the first step is a small one.
Start with skills and training.
You are the one holding it together. Put an AI-powered piece of the system to work today, or learn the standard alongside people doing the same job at other builders.
