Does anyone know of another company other than Square who does not reuire CVV? 

I've had a lot of loss in collection because customers won't give me the CVV and I can't charge their card. I've tried to leave many messages and sent multiple invoices.

I am not aware of one.  CVV number is required for any purchase where the card is not present as a layer of protection.  This requirement by Square and many others keeps the chargeback down and the processing fees down. 

If they are using Square invoices you can assure them that you and Square don't see that information once submitted.
