The Legacy Trap.
A flagship estimating tool trapped in a single-OS desktop era, with no path to the cloud.
For decades, Craftsman Book Co. accumulated invaluable reference data for the construction industry. However, their flagship estimating software was trapped in an outdated, single-OS desktop environment.
They needed a partner to safely orchestrate a complex migration to the Cloud without disrupting their large, dedicated user base — architects and contractors who depended on the platform daily.
- Single-OS Windows desktop application, no cross-platform access
- Decades of proprietary cost data locked in legacy formats
- Large established user base that could not tolerate disruption
- No internal technical leadership to drive the transformation

The Boutique Difference.
Three principles that separated this engagement from a typical outsourcing contract.
Acting CTOs, Not Just Coders
We didn't just wait for tasks. We stepped into the role of technical leadership, defining the entire cloud strategy, selecting the right stack, and guiding Craftsman through their complex digital transformation.
No Trial-and-Error
Given the stakes and the established user base, we couldn't afford mistakes. We meticulously mapped out the enterprise cloud architecture before a single line of code was written.
Preserving the Core, Modernizing the Shell
We ensured their decades of proprietary data-gathering processes remained intact while completely overhauling the user interface for a seamless Web/SaaS experience.
The same founders who designed this engagement still lead every Roxosoft project today.

Cloud Architecture Planning
End-to-end Azure architecture designed for multi-region availability, auto-scaling, and zero single points of failure across the full SaaS stack.
Modern Web-based UI/UX
A ground-up redesign of the estimating interface — responsive, accessible, and optimized for the daily workflows of architects and contractors.
Production-ready, Zero-Downtime Deployment
Comprehensive QA coverage across unit, integration, and end-to-end tests ensured a smooth cutover with zero downtime for the existing user base.
Craftsman Today.
A seamless transformation from legacy desktop to cloud-first platform.
The legacy estimator was smoothly discontinued, replaced by a robust, multi-platform SaaS product. Craftsman successfully navigated the digital transformation, strengthening its position as a trusted resource for US architects and contractors in the cloud era.
"Roxosoft didn't just build software — they led our entire cloud transformation with the confidence and ownership of a founding CTO."
