When modifying an order—whether by removing items or processing returned goods—you have three options for adjusting the document:
Modification Options
Updating the Original Invoice
Items are added or removed directly from the original invoice.
This option is primarily used by non-VAT payers who do not issue tax documents, thereby avoiding customer confusion.
Creating Corrective Tax Documents (ODD)
Used by VAT payers.
A new document is issued for the original invoice that reflects all the changes made.
Creating a Corrective Document and Preventing Further Changes
Only one change is processed, and subsequent modifications to the order will not update the corrective document.
All settings can be found on the Billing Rules page in the Additional Billing Settings section.
Informing Customers
If you use the Fakturoid Document Sending feature, customers will be automatically notified of every modification.
We advise consulting with your accountant to ensure the proper accounting treatment of all changes and to address any potential tax obligations.
Additional Procedures for Specific Situations
How to Proceed When Some Replacements on the Corrective Document Are VAT-Free?
If you encounter a situation where some replacements on the corrective document do not include VAT, please refer to our detailed article, Why are some replacements VAT-free on the corrective document?
The Corrective Document is Not Issued Immediately
If you process a refund via the Shopify Payment gateway, the corrective document may be delayed. Due to limitations imposed by Shopify, this process may take up to 36 hours.
