When you refund money in Shopify, the revenue of an order that was already invoiced changes. You should not simply edit or delete the original invoice. A clean way to document the refund is its own document that references the original invoice.
General overview, not tax or legal advice. Check individual cases with your accountant.
Why not just edit the invoice?
An issued invoice is an accounting record. If it changes afterwards, it no longer matches what was booked and sent to the customer. A proven approach: the original invoice stays, the refund is documented as a new document with its own number and a reference to the original. Whether a formal invoice correction is legally required or a reduction of the taxable amount is enough depends on the reason for the refund; either way, the VAT split must be traceable.
Partial refunds
With partial refunds, it must be traceable how the refund splits across VAT rates. If the order has lines at different VAT rates and you refund only an amount in Shopify without linking it to lines or shipping, that split is not clear. The simplest way is to refund via the order lines – which is also the path Invoice Autopilot supports automatically.
Several refunds
If an order has several refunds, one document per refund is clearest: each document then matches exactly one repayment you also see on your bank account.
How Invoice Autopilot handles it
- For every attributable refund against a finished invoice from the app, a separate credit note is created automatically, with its own number range and a reference to the original invoice – as a PDF/A-3 with embedded e-invoice. Amounts already covered by a cancellation or correction credit note are not credited twice.
- Partial refunds without line or shipping details, refunds without money and orders invoiced elsewhere are shown for review instead of guessing.
- Optionally, credit notes are also created for cancellations and later reduced orders.
