Nordica Invoices

EU-correct invoices, credit notes and packing slips, by Variegata Nordica.

An invoice for every order, by itself, with numbers that never skip.
Refunds and cancellations get a credit note that refers to the invoice.
Every invoice is stored once with a fingerprint, so you can prove it was never changed.
Prices, discounts, shipping and VAT exactly as the customer bought them.
EU VAT number check, reverse charge and export wording, VAT per rate.
A business invoice with payment terms for resellers, a simple receipt for everyone else, in Danish or English.
An Invoice button on your customers’ order page (new customer accounts).
A tool, not legal advice.

Install it from the Shopify App Store, then open it from Apps in your Shopify admin.
