Problem

Metrifox needed a billing and revenue operations product where a pricing bug isn't a UX papercut, it's lost revenue. It had to meter usage, enforce limits, automate invoicing, and turn every interaction into a chance to grow revenue, protect margins, or expand accounts.

What I built
  • The product design and design engineering for the billing product, from the first version through shipped surfaces.
  • The Discount Engine and Smart Billing Rules Engine, turning pricing decisions into configurable logic instead of one off exceptions.
  • Usage metering down to the token, with real time spend limits and expansion signals that surface added MRR before a rep has to ask.
  • CPQ prototyping to take deals from quote to cash without leaving the system.
  • A full interface redesign of the core billing surfaces.
Outcome
  • 35% pricing efficiency gain from the Discount Engine and Smart Billing Rules Engine.
  • 30% improvement in UX speed on core flows after the interface redesign.
