Three questions before the payments migration

Fictional sample. The company, dates, and figures are invented to show a page of open questions; replace them with your own.

Card payments move from the current provider to the new one on 1 December 2026. Three decisions are still open. Each chapter gives the context and the options; answer all three in the form at the end and send response.json to Lena Ortiz, who runs the migration, by 7 November.

1. How long do we run both providers?

While both providers run, a refund must go back through the provider that took the payment.

Refunds arrive up to 120 days after a payment; 96% of them arrive within 30 days (refunds from January to August 2026). A shorter overlap saves the old provider's monthly fee of €4,200 but sends late refunds through a manual process.

Overlap Refunds handled automatically Old provider fees
30 days 96% €4,200
60 days 99% €8,400
120 days 100% €16,800

2. Who approves a failed-payment spike?

The new provider's decline codes differ, so the first week will look like a spike in failed payments.

Today a failed-payment alert pages the on-call engineer at 3% of payments in 15 minutes. During the first week the payments team expects 4–5% while the code mapping settles. Someone has to decide whether that is a real failure or the mapping.

3. Do saved cards move, or do customers re-enter them?

312,000 customers have a saved card. The providers can transfer tokens, but only in one batch.

A token transfer takes one night and needs a freeze on card changes from 22:00 to 06:00. Without it, every customer re-enters their card on the next purchase; the pilot on 2,000 customers lost 6% of those purchases at that step.
