BOS

BOS is a phone-first construction project management software developed by Builder Operating System Inc. based in Hayden, Idaho. It provides scheduling, estimating, accounting, and change order management for custom and production homebuilders, remodelers, and design-build firms. The platform is designed to run on mobile devices in the field, allowing superintendents to update schedules from their phones even in the rain.

The software costs $199 per month and includes unlimited users and unlimited builds. There are no contracts, no setup fees, and no onboarding charges. Founding builders who sign up first receive a free one-on-one session with the founder, Todd Sullivan, to set up their first live job.

The platform integrates with QuickBooks, allowing vendor invoices to cross over as Bills with one press. It also includes a client portal, a storefront, and the ability to generate client invoices through a personal Stripe account. Additional features include time clock, mileage tracking, equipment hours, and photo and video uploads.

Todd Sullivan, the founder, describes the system as replacing the whiteboard nobody updates, the spreadsheet rebuilt every job, and the folder of PDFs on a desktop. He emphasizes that if a superintendant cannot update the schedule from their phone, the schedule is merely a document rather than a plan.

The pricing model charges a flat rate of $199 per month regardless of the number of users, unlike competitors that charge per seat. For example, while other software might cost $454 for 15 users, BOS remains at $199 for the same number of people, ensuring the field team is fully included.

The software is intended for use on iPhone, iPad, and PC, with a focus on mobile accessibility for superintendents in the field. It allows users to move tasks and automatically updates everything that waits on them, including trades, inspections, and milestones.

The platform manages the entire project lifecycle from lead to closeout, including blueprint redlines, takeoffs, and client document generation. It is specifically aimed at custom and production homebuilders, remodelers, and design-build firms.

The service is scheduled for release in September 2026. It is currently rated 4.5 out of 5 stars on Trustburn based on 4 reviews.

Some reviewers praise the ability to have a single system that connects the office, superintendents, and crews without pinching or zooming on small screens. Others note that the schedule matching the actual job site conditions is a key benefit.

The founder offers a free setup session for founding builders, including a one-on-one call by phone or video to load a real job with schedules, estimates, and cost codes. This ensures the tool is working within the week rather than someday.

The software includes a document builder, templates, and plans with redlines and takeoffs. It also features a client portal and a storefront for managing client interactions and proposals.

The system handles change orders, purchase orders, invoices, and payables, ensuring that the estimate, invoices, and draws all read from the same job record. This prevents discrepancies between what is bid and what is sent to the lender.
