Hi @aha-co-creatie,
If the order is already paid you will have to add a filter to make sure the order is editable. If this is the case please add the following filter to the functions.php of your child-theme:
add_filter( 'wc_order_is_editable', '__return_true' );
If you never worked with filters or functions.php before please read this first: How to use filters
Once the order is editable go into the order and simply remove the VAT from each line (click the pencil icon next to every item) and hit ‘Save’ when you are done removing the VAT of every line. Make sure the order total is correct. This should be the case but double checking is always a good thing.
And maybe for the future consider a plugin like EU Vat assistant.
I hope this helps!
With kind regards,
Michael
