Driver 01
No usage-based pricing
Consumption pricing that can't be offered without manual invoicing.
Migration playbook: Stripe Charges (legacy) → Stripe Billing and usage metering
Stripe Charges to Stripe Billing and usage metering
Rebuild billing on Stripe Billing: subscriptions and usage-based pricing, tax calculation and a self-serve customer portal, with idempotent webhooks underneath.
Migration drivers
Why teams make this move
Driver 02
Sales tax and VAT
Calculating tax by hand, or not at all, as you sell into more regions.
Driver 03
Involuntary churn
Revenue lost to failed renewals without automatic retries and card updates.
Execution sequence
How the migration runs
Each phase ends with a check you can verify — data parity, error rates, latency — and the rollback path is agreed before any traffic moves.
- 01Phase
Product catalog and pricing
Modeling subscription tiers, add-ons and metered usage in Stripe Billing.
- 02Phase
Webhooks and idempotency
Webhook handlers for invoice.paid and customer.subscription.updated that are idempotent and safe to retry.
- 03Phase
Customer portal
A self-serve portal where customers update cards, view invoices and change plans.
- 04Phase
Stripe Tax and Smart Retries
Turning on automatic tax calculation and machine-learning-based retry schedules.
Risk prevention
Pitfalls that derail this migration
Risk 01
Non-idempotent webhooks
Charging twice or granting duplicate credits when Stripe retries a webhook delivery.
Risk 02
Proration surprises
Misunderstanding how Stripe prorates immediate upgrades and downgrades.
Risk 03
Price IDs in client code
Trusting price IDs from the browser instead of validating products on the server.
Before and after
What we measure
We take a baseline before any change and report the same numbers after cutover, from your own tools. They are the evidence of whether the migration worked — not figures promised in advance.
- Recovered revenue
- Failed payments later recovered, from Stripe reports
- Billing tickets
- Support tickets about invoices and cards, per month
- Webhook errors
- Failed or duplicated webhook processing events
