Love this app · I have been a general contractor for a few years now and have always used word, quick books, or Adobe to create estimates and invoices. They work ok as long as you don’t need to change a lot of info with them. This app has to be the simplest set up and so easy to use my kids could send me invoices for chore money lol. But in short it’s a great app that is easy to use and set up for mobile use. I would recommend this to anyone and everyone.


Awesome · Excellent as general contractor class B does everything I need for me and I can add pictures to it.

Great app! · I’m a general contractor, this app makes my like so much easier. There are some changes that could put Joist over the top but it truly is a great product.
