Project Progress
Everything your build needs. In one place.
Built for the realities of construction — not adapted from generic project management software. Every feature earns its place.
Project Hierarchy
Organize every build into Major Milestones, Milestones, Sub-Milestones, and Task Cards — a structure that reflects how construction actually works.
Interactive Gantt Charts
Drag-and-drop scheduling with predecessor logic built in. Move one task and the entire downstream schedule updates automatically.
Cost Estimation
Build T&M cost entries with labor rates, material costs, and markup. Aggregated totals flow up through the project hierarchy in real time.
Team Collaboration
Invite crew, assign roles, and share real-time updates. Subcontractors get exactly the access they need — nothing more, nothing less.
Invoicing & Billing
Generate professional invoices directly from your project data. Track payments, sync with QuickBooks, and get paid faster.
Mobile Ready
A full-featured PWA that works on any device — online or offline. Clock in from the job site, capture receipts, log progress. Done.
Smarter Billing for Custom Home Builders
BuilderOS transforms how you track and bill for Construction Management time. Instead of burying CM hours in generic overhead, we organize them by project phase — Foundation, Framing, Plumbing, Drywall, and more.
Know Where Your Time Goes
Track how much management time each project phase actually requires. These patterns become your most valuable asset — turning gut feeling into data you can use on every future estimate.
Support Any Contract Style
BuilderOS supports all major residential contracting approaches:
- Cost-Plus: Markup on actual costs for profit (typically 10–15%)
- Hard Bid: Fixed price contracts with built-in change order management
- Construction Management: Transparent billing with separate profit + CM burden (typically 13% CM + 10% profit = 23% contractor fee)
Predictable Profitability
When your true CM burden is visible, setting accurate markups becomes data-driven — not guesswork. Fewer client disputes, more margin retained on every project you complete.
Example: CM Billing Breakdown
$400,000 residential project
Track your actual CM hours by phase to validate your 13% estimate and sharpen your markup on every future project.
