Estimate & Invoice App for Contractors
Fast, Accurate Estimates for Field Service Professionals
ProsPrice Generator is a mobile tool built to help field service professionals calculate and present service prices quickly and accurately. For contractors in the field, speed and professionalism are critical. The app was created to solve this by letting users generate estimates, presentations, and client-ready invoices with just a few inputs.
Lead Product Designer
2023-2024
The Story
Design rarely follows a neat, linear path. I joined ProsPrice Generator in July 2023 when the app was already underway, with a Figma prototype, set UI direction, and a tight deadline for MVP 1.0. There was little room for exploration, so my role focused on refining what was already in motion.
My Journey
As the Lead Product Designer, my role was to shepherd the app from a raw MVP to a polished V2.
The initial version was functional, but it needed to evolve into a more robust and intuitive experience to meet user needs truly.
I focused on immediate usability wins: improving accessibility, enhancing readability, and designing a new barcode scanner flow despite technical limitations.
The Roadmap
How do you transform a rushed, partially defined prototype into a polished, user-centered tool? This was our core challenge. I entered a project where the colors, wireframes, and UI were already set, and there was no time for broad exploration. The work became about solving usability gaps and advocating for the user within those constraints.
Real-world testing, including running the scanner flow at Home Depot, revealed pain points that guided the redesign. One of the biggest technical challenges was the sluggish API. The first version depended on scraping data in real time, which made responses slow and unreliable. For V2, we shifted to a cached API that delivered results almost instantly, dramatically improving speed and dependability in the field.
Working closely with the client and development team, my process was iterative and practical. We mapped real user journeys and built interactive prototypes in Figma to test solutions. Every design decision, from refining microcopy to reworking product management, was about bringing clarity and efficiency to the contractor’s workflow.
The differences are clear. V2 brought better spacing, cleaner type, aligned icons, more descriptive microcopy, and consistent use of color to guide actions and states.
What We Built
The redesigned ProsPrice app successfully launched and is now live on both the App Store and Google Play. The updated design, enhanced features, and improved user experience delivered a more professional and efficient tool for contractors. The V2 launch transformed the app from a basic calculator into a comprehensive workflow tool, supporting faster quoting, clearer client communication, and more streamlined sales processes.
Key Takeaways
This project was a powerful lesson in how thoughtful design intervention can elevate a product, even with significant constraints. Balancing a client's immediate needs for an MVP with the long-term vision for a user-centered product taught me how to prioritize effectively and advocate for design improvements that deliver real value. It reinforced that the best digital tools don't just provide a function; they solve real-world problems with clarity and ease.
