A subscription and billing engine that converts
Designing a usage-based billing and onboarding flow that removes friction between sign-up and first value.
In short
SaaS build, in short
- A metering pipeline where every invoice traces back to its events
- A single pricing engine covering proration, upgrades and refunds
- A self-serve plan and seat management flow
- An onboarding flow tuned to reach first value quickly
What made this hard.
Billing is where SaaS products quietly leak revenue. Plans change, usage meters drift, proration gets miscalculated, and a confusing upgrade path costs conversions the product earned elsewhere.
The goal was a billing core that finance could trust and a checkout flow a user could finish without thinking.

The build, step by step.
Metering you can reconcile
Usage events are recorded once, deduplicated and aggregated on a schedule, so an invoice can always be traced back to the events behind it.
Proration done right
Plan changes, upgrades and refunds run through a single pricing engine with tests for the awkward edge cases that usually slip through.
Onboarding to first value
We mapped the path from sign-up to the moment a user gets something useful and removed every step that did not earn its place.
Self-serve plan management
Customers change plans, seats and payment methods without a support ticket, with clear previews of what they will be charged.
What you walk away with.

Usage is metered once and reconciled, and all plan changes run through a single pricing engine with tests for proration and refunds. That removes the quiet miscalculations that usually cause leakage.
Yes. We build on established providers such as Stripe rather than reinventing payments, and keep the billing logic in your domain so you are never locked to one provider.
Self-serve plan, seat and payment changes are part of the build, each with a clear preview of the resulting charge, which cuts support load and improves conversion.
