Stripe Certified Professional Billing Architect

Migrate to Stripe with zero downtime. No drama, no surprises.

I led the migration of Babbel's recurring billing — hundreds of millions in revenue — from Adyen to Stripe with zero downtime. Your migration gets the same playbook.

The problem

Why billing migrations go wrong

Most teams only ever do one provider migration. The failure modes are predictable — if you've seen them before.

Live subscriptions can't be paused

Your customers renew every hour of every day. A migration that needs a maintenance window is a migration that loses revenue.

Card vaults don't transfer themselves

Re-tokenizing payment methods across providers — cards, PayPal, SEPA mandates — is where most migrations quietly bleed customers.

Nobody can audit what happened

Finance needs to reconcile every cent across two providers. Without verification pipelines, you're migrating on faith.

The playbook

How a zero-downtime migration actually runs

  1. 01

    Audit & inventory

    Every subscription, payment method, billing cycle, and edge case in your current provider — mapped before anything moves.

  2. 02

    Architecture & dry runs

    Stripe Billing flows designed for your model, idempotent migration jobs, and full rehearsals against production data copies.

  3. 03

    Staged cutover

    Cohort-by-cohort migration with verification at every step, rollback paths ready, and customers keeping their billing day and auth.

  4. 04

    Reconciliation & handoff

    Full audit trail proving every cent landed where it should, plus documentation and monitoring your team owns going forward.
