Frequently asked questions

How customizable are the invoices?

We have a plethora of different invoice styles to choose from, from graphically pleasing to more professional business-friendly. You're able to customize the page size, font size, logo, color (for graphic intensive invoices), and so much more. Invoices are dynamic and reformat based on your content. If one page isn't enough, a second page will be created.

I didn't find a template I liked. What can I do?

No problem at all. We are constantly adding new templates to the library. If you want something specific, just send us an email with your request and we can create the template in a matter of days.
