Retail chain running separate payment providers for online and 28 physical stores — no unified view of customers, painful reconciliation, and inconsistent refund processes

  • Single view of customer across online and in-store purchases
  • Reconciliation time cut from 2 days to 30 minutes daily
  • Cross-channel refunds enabled — buy online, return in store
  • Payment acceptance rate up 4.2% with local acquiring
