Simple Invoice is a great add-on for Shopify. In our case we are going to start with a store from Spain and it fully meets the expectations that the invoice appears professional and meets legal requirements.
First I started for free to see how it worked. I liked it and go to the Pro subscription which is $ 6.99 but it is totally worth it. I work from Spain and I have adapted the way of entering the CIF or NIF both in the Shopify registry and in the pdf of the invoice. They responded promptly and professionally.
Fully recommended
