Invoice payment method (PLEASE HELP)

[Zekule]

Guys,

I'm configuring a VM 2.0 on Joomla 1.7.3 E-Shop and I need 3 payment methods.

I managed to configure - Credit Card Payment method
I managed to configure - Cash on Delivery

But I can find any good Invoice Payment Method.

Anyone can help me resolving this issue please?

Thanks in advance.
