Review/Feedback please: Entry level non-cloud/non-SaaS accounting app for solo operators

Hi,

I'm building an app and I'd like some review/feedback/constructive-criticism please.

It's an accounting app targeted at solo operators (for example, freelancers, consultants, contractors, side gigs etc). Due to the niche target market, it only has a subset of the functionality found in other accounting apps, but this also means that's no unnecessary clutter. In other words, it's stripped down and simple, but (hopefully) fully functional for the target user.

Also, it's non-cloud/non-SaaS in the sense that ... the data file is stored on the user's computer instead of being stored in the vendor's cloud and it's in an accessible open data format. In other words, the user has full control over their own data.

If you're interested, here are some links:

Web edition of the app: https://www.gigobooks.com/webapp
The website (but it needs a re-design): https://www.gigobooks.com
The open source / desktop edition of the app: https://github.com/gigobooks/gigobooks

Some questions to spur discussion ...

Do you think it has enough functionality for the target market/user? What other additional features might be needed?
If you are a target user, would you use such an app? If not, why not?

Any comments, criticisms, questions, are welcome and appreciated.

Thanks for reading, and thanks in advance for your comments and thoughts!
