How to create a printable invoice

Hi guys, I have been using zoho creator for the past week and I find it amazing!
I have build a simple time tracking app and a project management app for my own use.

I would like to use zoho creator for invoicing as well - at the moment I just use a word file, edit it and save/print each time a do an invoice.

All I really need is a set layout that automatically fills in invoice number and allows me to add a few details and then print.
What is the best way to do this in zoho creator?
