Most Contractors Outgrow Their Accounting System Long Before They Realize It.

We have watched it happen dozens of times. A contractor starts with QuickBooks, then suddenly they are doing $20 million a year and their books cannot keep up. Change orders fall through the cracks. Job costs are guesses. The surety company wants a WIP schedule and no one knows what that means.

That is why we built the BMS Growth Pathway — a three-stage system that scales your accounting infrastructure alongside your business, so your financial systems are never the thing holding you back.

Stage 1
The Foundation
(Startup to $5M)

We set up your bookkeeping, job costing, AIA billing, and QuickBooks from day one. Monthly bookkeeping handled so you can focus on building. We tell you when it is time to move to Stage 2.

Stage 2
The Growth Platform
($5M to $25M)

We implement Sage 100 Contractor — purpose-built for construction with job costing, AIA billing, certified payroll coordination, and subcontractor management. We migrate your data, train your team, and support you as you grow.

Stage 3
The Enterprise Platform ($25M and Above)

We implement Sage 300 Construction and Real Estate — the industry standard for serious general contractors. Multi-entity, WIP reporting, full enterprise accounting. We have been implementing Sage 300 CRE since the Timberline days in the early 1990s.
