Customer Reviews

Great App

I use Joist daily for my contracting business. It represents me in a very professional manner to my customers. Only the following few things to add or improve for a 5 star rating:

1). Add the ability to list line items under multiple group or subject headings.

2). It would be very helpful and less confusing to my customers if items did not automatically total at the bottom of estimates. Often on a single estimate I'll give my customer multiple pricing options, If these optional items are totaled at the bottom the customer can become confused. Need to be able to toggle that off or select only items I would like to total.

3). Another feature I'd love to see is the ability to input a job title at the top and have the estimate and invoice sorted by this name. I have clients with multiple properties so this would be a very valuable feature!

Don't get me wrong, this app works as designed and I've never had an issue with the functionality the developers have included. That being said, it seems as though Joist was designed more for estimating and invoicing goods or products rather than services. Again, with the previously mentioned tweaks it could be perfect!

Developers of Joist - Thank you for creating this app and continuing to improve it!

Great app

It's really nice that it's free, I would of paid $20 for this app without hesitation. I was using old estimating software on my windows computer for years and it was out of date. Now I bought a Mac, iPhone and iPad and this free apps works seamlessly with all 3. I literally just made a estimate on my phone at the job site, went to my truck opened my iPad and it was already on the app. I printed out the estimate in my truck, (wireless printer using my phones hotspot as wifi) gave it to the homeowner, he agreed, wrote me a check, I had him sign the estimate on my iPad and I emailed it right over it him. He appreciated how professional it was and getting it done right in the spot instead of waiting a few days. This is the best free app for contractors. If you want to pay $20, use construction cost estimator.

By far the best thing for my business

I own a small house cleaning business and downloading Joist was by far one of the best decisions I've made. I tried multiple invoice apps and none of them came close to Joist in terms of functionality, usability, and professionalism. It takes literally seconds to create a professional and complete looking invoice for my clients.

Both the iPhone app and website are excellent. I've had customers asking me what program I use because they were so impressed by my ability to create and email them a great looking invoice before I even leave their home.

I'd be extremely disappointed if Joist discontinued support of this app. Do yourself a favor and download it, you won't regret it!
