I just came across a really useful site for generating invoices online: www.invoicemachine.com. The site has a nice clean design and despite a few minor usability issues it's easy to use. It allows you to provide a link to an invoice online, track the history of an invoice and add payments. It also has an API so you could integrate it directly with say your issue tracking system for example.
You should try freshbooks, it's very good. There is a link to it from my
blog :)
Mmmm, storing your financial information online. If you are a regular
invoice-maker and you are running Mac OS X then Billings -
http://www.billingsapp.com/ - is the software you need. It's has all the
flexibility you need for managing your financial project related things.
It's not free, but is not that expensive.
