Keep it, switch to another template, or change any field, column and label yourself with a live preview. No code. Setup is your company and VAT details and a few clicks.
Konto IS connects your Shopify store to the Konto invoicing system.

Business buyers who enter a kennitala at checkout receive an XML e-invoice delivered through the official message hub.
