The app Makes nice invoices But when it comes time to send the invoice if you're not subscribed the customer does not receive it. You can't even take a clear screenshot to forward a copy of the invoice in another way. Screenshots end up blurry and not legible. If you're downloading this just to do a couple of quick invoices find something else. You will have to subscribe. Then, I got a new phone and they couldn't even locate my account all of my work was lost. I found another app w/ no issues.

Good app. I wish there was some expese stuff, but its fast and clean. It's not worth $100 a year though. And especially not when the competition is the Wave app which is slower by a smidge, but will integrate with H&R block that I have do my business taxes. And is free. I'd rather pay for this one, but not by subscription, and not that much. I pay 120-130s for my tax software every year and that is COMPLEX.

This app is awesome! Very easy to use and quick for making up invoices. Unfortunately since the latest update, the app won't even open up anymore, it's just stuck on the logo when it first opens, It won't go past it for some reason. Even Uninstalled and reinstalled, no luck. Very very unfortunate as I have all my billing info amd everything on it. Not sure what the deal is. A quick fix would be greatly appreciated!
