A customer paid 102.30 Euros. He got 99.85 Euros back. He was angry.
The system used the current rate during the refund. Rates change. This created a loss for the customer.
We fixed this by pinning the rate. We saved the rate at the moment of purchase. We use this same rate for all refunds.
The setup is simple:
- One database model.
- One service class.
- One fixed rate per order.
Refund disputes dropped to zero. The finance team saves hours of work every month.
Lessons for your business:
- Save the rate, not only the final price.
- Never use live rates for old transactions.
- Keep your code simple.
