[Slackbuilds-users] Invoicing application recommendation

[Andrzej Telszewski]

Hi,

Can anyone suggest an invoicing application?

Only something that you use personally and that works well.
Preferably no Java, web based is completely out of scope.

Preferably the application should have single functionality: making 
invoices, keeping clients and history.

Thanks!
