Designing a modular B2B billing system
Role
Lead Designer, 2024-2026
Sector
FinTech
A critical need of growing SaaS businesses, that is often overlooked in billing software, is the ability to accommodate regular changes to the prices, features and service allocations. As a SaaS offering grows and better understands it’s market, it needs a billing platform that will adjust accordingly, while maintaining a detailed historic record.
Modularity was our answer to this challenge--detaching features and parameters (price, quantity etc.) so that they can be modified and developed independently to fit customer needs, without having to create new billing models each time.

Inspired by industrial design, and modular manufacturing, I built a comprehensive design system to scale as the app matures.
