I have a small company and I needed a invoice software.
I was looking for a while and checked I think almost all ONLINE invoces systems wich can make my life more easy.
The one that I have found and using it till now is the Bilomat Online Invoice Tool.
Its german made so it works perfectly. The support is quick and very good quality.
invoicing is very impotent think if you are involve in online business.. iwas facing same problem since 2 months ..after surfing so many sites i got the solution. its a good for online invoicing ....
