FAQ
How did a customer receive a percentage discount on their order? There's no discount or voucher code applied.
This may not be a discount, but rather a result of your tax settings. Check that Collect taxes when shipping out of the European Economic Area is enabled.
If it's turned off, orders shipped outside the EU won't include VAT, which can make it appear as if the customer received a percentage discount.
I issued a refund to a customer, but the order total hasn't changed. Will I be charged VAT on this?
The original order total is immutable once payment has been made and the order is locked.
This ensures the original invoice remains a legally valid record of the sale and no historical tampering or can occur in your accounting trail.
When you issue a refund, that refund is recorded as a separate financial entry - not as an edit to the original sale amount.
So while the order total remains unchanged (because that’s what the customer originally paid), the refund offsets that total in your books.
A credit note serves this function as well.
