## DATABASE vs REVOLUT RECONCILIATION

### Orders Matched Successfully
- **353 orders** with valid Revolut IDs
- DB Amount: £593,450
- Revolut Amount: £588,950
- Variance: £4,500 (DB higher - fees?)

### Unmatched DB Orders (130 orders, £401,468)

| Payment Method | Orders | Amount | Status |
|----------------|--------|--------|--------|
| credit_card (POS) | 75 | £187,700 | Likely in orphaned Revolut |
| bank_transfer | 20 | £109,968 | Client verification needed |
| cash | 12 | £25,000 | Trust accounting |
| complimentary | 3 | £7,550 | Non-revenue |
| split | 5 | £16,400 | Partial match expected |
| stripe | 2 | £27,100 | Mislabeled (see corrections) |
| debit_card | 1 | £1,850 | Likely in orphaned Revolut |
| revolut | 1 | £25,900 | Order 530 - wrong ID format |

### Orphaned Revolut Payments (147 payments, £223,513)

These are Revolut payments without matching DB orders. Analysis:

| Type | Payments | Amount |
|------|----------|--------|
| POS Reader (Custom product) | 61 | £84,412 |
| Manual Entry (Custom amount) | 86 | £139,101 |
| **Total** | **147** | **£223,513** |

**Expected Match:** DB POS orders (76 orders, £189,550)  
**Gap:** £33,963 more in Revolut than DB

**Possible explanations:**
1. Some POS payments not recorded in DB
2. Non-event purchases (bar, merchandise)
3. Multiple tap payments per single DB order

---

## CORRECTIONS REQUIRED

### 1. Duplicate Orders (Cancel)
Orders 522, 523 are empty duplicates of Order 530:
- All created same second for same customer
- 522 & 523 have 0 line items
- **Impact:** £51,800 overcounted in original reports

## RECOMMENDATIONS

### Immediate Actions (SQL provided in SQL_FIXES_DEFERRED.sql)
1. ✅ **Cancel duplicates** - Orders 522, 523 (£51,800)
2. ✅ **Fix Order 568** - Change stripe→revolut, add Revolut ID
3. ✅ **Fix Order 530** - Add correct Revolut ID
4. ✅ **Link 42 POS matches** - Add Revolut IDs to matched orders

### Client Verification Needed
1. **Bank transfers** (£109,968) - 20 orders need receipt confirmation
2. **Pre-event cardholders** (£21,500) - Find matching DB orders for Nov 13-14 customers

### Investigation Needed
1. **34 unmatched DB POS** (£102,950) - Were these processed through different terminal?
2. **54 event-day orphaned** (£51,911) - Likely bar/merchandise, confirm with venue

### System Improvements
1. Ensure POS always captures Revolut payment ID
2. Add real-time reconciliation alerts
3. Daily automated matching reports
