JEDIK  It's a very nice application: simple but does what's needed. Some suggestions:

- some parts of the program are still in French, making it 100% localized in English would be nice;

- it would be nice if the program saved the windows postions as well as the column widths;

- ability to choose the columns displayed in the main windows by the user, adding 'case/project', for example;

- ability to edit invoices or at least undo some operations like 'cancel'.

I hope the developer keeps this project alive. Thanks for making it free! Kudos!

GTHING  Very simple program - cool concept. I like that it uses pages and it is easy to create new invoices and everything.

It seems to be stuck in Euros, and I can't figure out how to make iSous use US Dollars. Also, once you've created a client, I couldn't figure out how to edit or remove that client.

Definitely a program I will keep an eye on though.
