Why is the PrestaShop revenue higher than the Op'art Stat module revenue?
A revenue difference can come from the calculation rules and scope selected in each tool. Identify the PrestaShop report being compared: refund handling depends on the report and its version.
The module calculates revenue excluding tax from recorded orders. Only refunds present in the order-line refund fields used by the module are deducted; shipping is included or excluded according to your setting.
Under Global Settings, check in particular:
- Status of valid orders: only selected current statuses are included; the module’s help says to include partial refunds among valid orders;
- the settings to exclude shipping and free orders;
- the date used: invoice date by default, or order creation date when that option is enabled.
Then compare the same period, store, currency and filters, taking recorded order discounts and refunds into account.
For a reconciliation procedure, see How to verify that the data provided by the module is correct?
A return, credit slip or refund handled by another tool may not be recorded in those fields. The module therefore does not guarantee deduction of every refund or revenue that is always lower than PrestaShop’s.
