I've decided to stop using a great app because of it's limitations and quite heart broken at that. EDIT: I understand that the company needs to earn from their apps, but I'm not against the starter pricing and the standard pricing and I was willing to pay. I'm more disheartened about the LIMITATIONS of the paid app. 3 invoices a month is just too much.

Hello and thank you so much for taking time to review our app. Our pricing, which is one of the lowest around here, is necessary to keep our product alive. Development of a comprehensible invoicing tool requires a lot of time, people and energy - that's only possible with the kind support of our users. Thank you for your understanding.

Can't do decimals for quantities, for example .5 hours. Can't send via email. I have to download the pdf and email it via my email client. Clicking on "unpaid" invoices doesn't show any late invoices. Last I checked late invoices are considered unpaid. I really regret paying for a whole year upfront. Save your money people, there are much better options with a much easier to navigate UI.
