I've been using NoCreditCard dialer, and its been converting pretty well for me.

I was wondering if any of you use them and could answer my question concerning how they pay.

My friend is supposed to get paid today but they are asking for some number in this invoice. He says he doesn't know what number it is. Do any of you know?

"About the registration number, it is for fiscal & legal reasons, that you
register in your locality
for doing business. It is the number that the
authorities have given you that we require.
This may be important for VAT (MwSt) reasons as
you are invoicing to a foreign company."

Thanks,
