How to verify that the data provided by the module is correct?
To verify revenue, reconcile a short period containing only a few orders. Quantity × current catalogue price excluding tax is insufficient: the module uses amounts recorded on orders and applies its settings.
- Note the report’s period, store and filters. For an initial check, remove product, category, brand, attribute and feature filters.
- Under Global Settings, note valid order statuses, whether shipping and free orders are excluded, and whether invoice or creation date is used.
- In PrestaShop orders, select the same scope. A creation-date filter does not reproduce a period based on invoice date.
- For each included order, start with its recorded paid amount excluding tax, which already includes discounts. Deduct only refunds recorded in the order-line refund fields read by the module and apply the shipping exclusion setting. If a cart rule grants free shipping, account for it to avoid deducting shipping twice.
- If orders use several currencies, take each order’s recorded conversion rate into account.
- Compare the sum with the module’s revenue. If a difference remains, identify the order concerned and provide support with the period, filters and settings used.
Product, category, brand, attribute and feature filters trigger a calculation per order line, with allocated discounts. Checks using these filters must reproduce that scope and allocation too.

If a refund or return does not populate those fields, do not assume it has already been deducted. Have the order data checked before expecting agreement with another report.
