Ratings and reviews

I like ProBooks. It is the best estimate and invoice app. Emailing and texting estimates and invoices work well. The templates are presentable and not overbearing with lots of graphics. The subscription price is reasonable. Help from the developer is not instant, but he does reply. I asked for pinch zoom in preview and the developer released an app update within days. It lacks an option where users can add their own terms and conditions text into the Company Setup in Invoice Estimate Options.

When I'm sending my invoices out, I send them many different ways. I accidentally saved a setting for future reference and now when I want to send a picture I can only send it on Facebook messenger. I've looked all over to for where I can undo this and I can't find a setting for this. Is there a place to change this that you could tell me about? And if not, you should add it to your app. It would be helpful. Update: I was able to fix the setting. It has since been a super helpful app to use!

I've been working with the software since its inception as Invoice Maker Pro. This software fits my changing needs as my business grows thanks in part to the accommodating nature of its creator. Over the years I've contacted him regarding the pet peeves of working with software and every time the next upgrade happened, my specific issue was either resolved or updated in a way I could work with comfortably. I don't use nearly all the great features. Looking forward to checking out the new template
