Real-world project successes and client testimonials showcasing our adyen development expertise.
Adyen Unified Commerce for Retail Chain
Challenge
Retail chain running separate payment providers for online and 28 physical stores — no unified view of customers, painful reconciliation, and inconsistent refund processes
Solution
Consolidated online and in-store payments on Adyen's single platform: unified checkout online, POS terminals in stores, and one dashboard for all transaction data
Results
- 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
Technologies Used
"For the first time we can see a customer's full journey whether they bought online or in store. The reconciliation alone saves our finance team two days a week."
