So far great app. easy to use, interfaces well with other apps to create .pdf and .doc .... In the type of service provided for frequency or amount, only hours and days appear as options, but those can be adjusted to meet individual needs (i.e., number of pieces, etc can be added). So. very functional and user friendly plus t's free.

Inaccurate/Deceptive description regarding the "Free" version. I only create 2-3 invoices/month. Based on the desc of this app saying that you can create a limited number of invoices for free or upgrade to create unlimited invoices. Well, yes, you can create them, but you have to subscribe to be able to send or print them. So, if you are looking for a functional free invoice maker, keep looking. Also, I have a client who asks that the invoices go to 2 email addresses, which this does not allow.

Hi Sherry Anderson, thanks for the feedback. It is understandable that a completely free product is more attractive; however, to continue to support customers and develop updates/features, we need to hire staff and pay other services as well. If you have any questions, please don't hesitate to connect with us at

This is just to get you to pay a subscription. If you read the fine print, it tells you that you only have a limited number of invoices to make before you have to begin paying a subscription. They don't tell you what that number is, but after getting setup with the app and trying to send out your second invoice you find out it's only ONE invoice. I understand having a simple free version with ads, and having to pay for more features, but this really just a trial version to send one free sample.
