I've been using this app for a while to do invoices for my web design clients. The interface is sometimes a little unclear and the product could really do with some proper documentation, but once you get the hang of it it's useful.A tip for new users… If you want to mark an invoice is paid, you have to long press on it.

I downloaded this app to be able to issue invoices/receipts when I sell items online. However, I have found the app to be somewhat quirky, not very user-friendly, has no documentation of how to use it, and requires odd data for certain things. For instance, I can create items for sale easily enough, and I can attach those to an invoice easy enough, as well as create a client just fine, but then it requires an email address and phone number for all clients; most strangers from the internet are not going to divulge this info, nor am I comfortable asking for it, and finally, it has a place for payment methods, which is just a text box, with no description of what is supposed to go here. Additionally, once I create an invoice, I can email it, print, or save it easy enough, but I have found literally no way to mark an invoice as PAID, so everything just winds up showing as overdue. I’m rather disappointed in the app, because it does look nice and clean, but if I can’t mark things as paid, then what’s the point?

Invoice is amazing to use and I will continue to use it

I have the full premium service, however the app continually prompts me to “upgrade.” There is no way to edit what information for business or client appears on the invoice, even though it is input into the system. Also I cannot mark any invoices as paid, the system never changes the label from unpaid to paid. Really frustrating
