The challenge
Failed transactions and silent vendor timeouts were driving refunds and support volume the team could not staff against.
What we did
- 01
Introduced idempotent transaction handling with automatic retries and reversals.
- 02
Abstracted vendors behind one routing layer with live health scoring.
- 03
Rebuilt the wallet UX around status transparency instead of spinners.
- 04
Wired GA4 and CRM events so failures became measurable, not anecdotal.
