When I first started out it was just me. Didn’t know too much about anything although I always strived for professionalism. I use to do bids through text messages until somebody asked me for a “formal bid”....I freaked since I hadn’t a clue. To the day the least, I lost that job. Shortly after a buddy introduced me to Joist.....since I’m not tech savvy, I was skeptical but thought “why not?” Now looking back, I am truly grateful for my friend. This app single handedly taught me the entire process on how to do estimates, invoices, paid invoices, showed me the difference between those three, it also taught me in so many ways basic formats on how to bid projects for my business all the while looking extremely professional. Now days I get 90-95% of all bids that I submit all thanks to the joist app that literally takes me 5 min to complete from inside of my truck and from my phone.



This App of awesome, I've been looking for something like this for a while. As a new business owner just starting out and with not a lot of capital, I was searching for a free software that does what joist does.

Well most of the other software out there and there is a lot of options are very expensive and I couldn't afford to get them just yet but joist is absolutely free, very user friendly and extremely professional looking. You only pay if the customer uses the pay with CC or electronic check feature and even then it's a nominal fee.

Obviously it's missing some of the awesome bells and whistles of the other guys but I'm confident they are working to implement those features for future release. Either way joist is an great find and they now have a customer for life.

Great App!!

We have been using this app for a couple of years now for both of our businesses. We have a wide array of services and a growing clientele and must work from multiple locations. With the Joist app we can do billing, estimates, etc. in real time which allows us to all work on our own job responsibilities yet keep updated as to what others are doing without having to contact one another continuously throughout the day... I can see the estimates being done out in the field as well as they can see what billing I have done... and I really find the email opened notification useful - so when I send an invoice to someone via email, i am alerted that the client has opened it and received my invoices!
