The operating system for small builders.
Modules made for the way you actually work.
Project & phase management
Phases, tasks, daily logs, change orders, draws, photos, punch lists — every job, every site, in one place.
Subcontractors & ratings
Crew database, performance history, star ratings — visible at award time.
Bid management
Send invitations, collect proposals, compare side-by-side, award in two clicks.
Buyer portal
Branded selections, milestones, photos, and punch lists for your buyers.
Compliance built-in
Insurance & license expiry alerts. Block uncompliant sub assignments automatically.
Live profitability
Per-project P&L, budget vs. actual, pipeline margins — no month-end surprises.
Residential. Commercial. Remodel.
From a single custom home to a 30-unit subdivision.
New residential
Land → lots → plans → draws → buyer hand-off.
Commercial & multi-family
Subs, bids, compliance across multiple sites.
Remodels & renovations
Change-heavy jobs without the chaos.
On the jobsite or at the desk — same workflow.
Daily logs, photos, punch lists, time entry from a phone in muddy boots. Bids, draws, profitability from the desk. Fast on both.

- Offline-friendly forms
- Sub portal — no app to install
- Buyer hand-off in one tap

Procore and Buildertrend are great for 50+ person GCs. If you're a 2–25 person builder, they'll drown you in features you'll never use. SummitOS focuses on the few things that matter most.

Builders are switching — from spreadsheets and from the big guys.
"Replaced three tools and a wall of sticky notes. Onboarding took an afternoon."
"The compliance alerts alone paid for the year. We haven't had a stop-work since."
"Buyers love the portal. Selections used to take weeks of email — now it's a couple of clicks."
