Looks like it came from your business, because it did.

Fill in your letterhead once in Settings: legal name, address, tax number, email, phone, website, how to pay, your terms, a footer and an accent colour. Every PDF invoice uses it. You can also choose your own number format, such as a different prefix or number of digits.

The difference

The usual way

A generic invoice looks like a generic business

Word templates break, numbering slips, and the payment details are wrong on half of them.
