I'm looking for some new invoicing software that's free or inexpensive, has the ability to have invoices styled to my liking, and hopefully able to write to PDF intrinsically. I don't need much, really - the ability to store clients, calculate bills hourly or via retainer, and the ability to generate invoices from the data fed are all I want. Windows XP or web-based, either is fine with me. I'm looking to do something that would not attach itself to my web hosting at all because I have clients who do not use me for web work but instead offline design.
Anyone have any ideas?
