## Calculation

```
Rolling SUM(total_paid_tax_incl) for paid-state orders today vs the same-weekday baseline - catches a broken checkout / disconnected gateway before the merchant notices.
```

PrestaShop order classification uses the order-state machine: paid = `current_state` in (2 Payment accepted, 3 Processing, 4 Shipped, 5 Delivered, 9 Backorder paid, 11 Remote payment accepted); shipped/fulfilled = (4, 5); refunded = (7, 15); cancelled = (6); payment error = (8). Read live from the PrestaShop Webservice API and snapshotted nightly into the Nerve Centre KPI store.
