I have this recurring question from customers purchasing for their company but use their own credit card so then SHOP fills out the info… I just edit the PDF invoice and return it back to them - it is fast and it works - Shopify should have this option integrated at no charge to all owners of ecommerce businesses - we should not have to pay for an app that we don’t really need on a daily basis. But this option with editing PDF file makes my customers at ease, they can charge their employer for the purchase on their expense account and the company has an official paid invoice with all the information needed,
