Hi Garret!
Perfect. Thanks for your reply, much appreciated.
Hi Bas!
A part of having the order changed its very important that the SUBTOTAL label adds the shipping cost (without VAT) to the product sum.
They are requirements related to Spanish Tax, and invoice table should look like this:
Product × 1 76,09€
Shipping cost 4,96€
Subtotal 81,05€
VAT 10% (product) 7,61€
VAT 21% (shipping) 1,04€
Total 89,70€
Many thanks!
