The Problem

Sound familiar?

Implementing usage billing from scratch on top of Stripe takes 4-6 weeks

Pricing model changes require re-engineering the billing engine

Proration, overages, and commitment discounts are notoriously hard to get right

Proration Engine

Automatic proration when customers upgrade, downgrade, or add seats mid-cycle.

Overage Handling

Cap usage, block access, or bill overages automatically when limits are hit.

How It Works

Set up in under 2 minutes. No complex configuration.

Frequently Asked Questions

How is this different from Stripe Billing?

Stripe Billing handles payment collection. We handle the complex pricing logic — tiers, overages, commitments — and feed the result to Stripe.
