I am selling the book I wrote called “Turn your cottage into money” and needed to have an invoice, but I wasn’t sure what to put on it and I didn’t really want to set it up. So, I naturally searched Google and found Vortex42. They have a TON of forms to help you with your business. One of them I used is the invoice template. It worked great and very easy to use.
Here’s one I just did for a realtor. Click on the link: Realtor-invoice
Try it and send me a link to what you used.
Good luck and have fun growing your business.
