PSP & billing migrations
End-to-end migrations from Cleverbridge, Adyen, Recurly, Chargebee, BACS-only setups, or Stripe-to-Stripe rebuilds - including new Billing & subscription configuration.
PSP & billing migrations
Migrations are the highest-stakes work we do. A single missed renewal, a duplicate charge, a tax line item that suddenly looks different on a customer's invoice - any of these can erode trust faster than the migration itself can rebuild it.
We've migrated hundreds of thousands of customers onto Stripe - from Cleverbridge, Adyen, Recurly, Chargebee, BACS-only setups, and other Stripe accounts. Every migration is sequenced, dry-run, and validated before a single live customer is touched.
Where we come in
Cleverbridge, Adyen, Recurly, Chargebee - each has its own data shape, mandate model and tax treatment. We build the migration plan to match.
Splitting accounts into per-region or per-property Organisations, restructuring marketplaces, moving off Connect platforms.
Migrations are often the moment to redesign the billing model. We design Subscriptions, Invoices and Tax alongside the migration so customers land in their final state.
Direct Debit mandates have specific portability rules. We handle the legal, technical and operational steps to move them without losing collection rights.
Methodology
Source audit and data mapping. We document exactly what exists today and where it has to land.
Strategy and sequencing. Region by region, brand by brand, cohort by cohort - small enough to validate.
Dry-runs against production-shaped data. We compare expected vs actual before any live customer moves.
Zero-downtime switchover. Subscriptions and mandates carry over with no missed renewals.
Post-migration support, structured reconciliation and a runbook your team can keep using.
How we de-risk it
Migrations rarely succeed as single cutovers. We design them as sequenced phases - small enough to validate, small enough to roll back.
Before any customer moves, the full migration runs against representative data in a non-production environment.
Every migrated record carries metadata that lets your finance team reconcile the new world against the old, without manual matching.
