The Business System for General Contractors

Stop Running Your GC Business From a Spreadsheet and a Prayer

Most GCs in their first five years are losing money on jobs they don't even know are underwater. Contractor OS gives you the job costing, estimating, scheduling, and automation to build a profitable operation — without the enterprise price tag.

Sound Familiar?

You're Good at Building.
The Business Part Is a Different Job.

You're not failing — you just don't have the right system yet.

The Invisible Money Loss

Jobs finish and you have no idea what the real margin was. You're pricing from gut instinct and finding out too late that you lost money. Again.

68% of GCs
can't tell you their real profit margin on a job in progress

The Single Point of Failure

Everything runs through your phone and your memory. Every schedule, every promise, every follow-up. If you get sick for a week, your business stops.

10pm texts
from clients asking 'where are we at?' because there's no system

The Amateur Appearance

You know your work is as good as the bigger guys. But your estimates look like they were made in Excel, your invoices are late, and your clients compare you to GCs with real systems.

First impression
is the difference between the $500K job and the $50K job
The Solution

Contractor OS Is the System You've Been Trying to Build From Scratch

Everything you need to run a profitable contracting business. One platform. No duct tape.

Job Costing & Profit Visibility

Stop guessing if a job is making money

See real-time profit margins on every active project. Know exactly where your money is going before the job wraps — not after.

Estimate Builder

Stop underpricing and losing money on bids

Build accurate estimates 3x faster with material catalogs, real labor rates, and automatic markup. Send proposals that look as sharp as the big GCs.

Client Portal

Cut 80% of 'where are we at?' phone calls

Give clients their own portal with project updates, photos, documents, and approvals. Professional communication without the constant texting.

Crew & Sub Scheduling

Replace the group text chain with a real system

Dependency-aware scheduling that understands construction workflow. Everyone knows where they need to be, with automatic conflict detection.

Automation Engine

Handle the paperwork without touching it

Follow-up sequences, invoice reminders, lead nurturing, and status updates — running in the background while you focus on the work that matters.

Invoicing & Payment Tracking

Stop invoicing late and chasing money

Draw schedules, progress billing, retainage tracking. Auto-generate invoices from milestones and get paid faster with professional payment requests.

Get Started Fast

From the Field

Here's What GCs Who Were Where You Are Have to Say

Before Contractor OS, I was finishing jobs and praying the numbers worked out. Now I see real margins in real time. Last quarter I caught a $14K cost overrun before it ate my profit.

I went from spending Sunday nights doing estimates in Excel to sending professional proposals in 20 minutes. My close rate went from 30% to 55% in three months.

My clients used to text me at all hours. Now they check their portal. My subs know the schedule without me calling everyone. I actually took a weekend off last month.
