### 🔍 Bug Resolution Details
**Issue**: Customer reward points showed 10x higher values (375 displaying as 3750)
**Root Cause**: Using `FLOOR(final_total)` calculation instead of actual `rp_earned` database field
**Solution**: Updated all calculations to use Ultimate POS's authoritative reward point fields:
- `contacts.total_rp` - Current customer balance
- `transactions.rp_earned` - Points earned per transaction  
- `transactions.rp_redeemed` - Points redeemed per transaction
