I have looked for a good online invoicing software for my freelance work and a small company.
I think I haved tried almost all well known invocicing services availible on the web and everytime sometime was not good. One was to expensive, other one have almost no support, and the other one was limited in customization.
One day I have meet my old friend which as well works as a freelancer now. I asked him what software does he use to process all the invoices and quotes to his clientes.
He have recommended me the Billomat Online Invoicing Tool, as its cheep, have a reliable and quick support and have a lot of thing that You can customize.
I have tryied the basic free plan, and it looks like its really working and have all the stuff that I was missing in other aplications.
I really recomend Billomat Online Invoicing tool for every freelancer and a small company othe there, especially if You dont like all the paper work.
Hope that was helpfull :).
