Pay on Invoice only for business Customers

[sined123]

Hi together 

Is there any way that only customers who enter a company name in the billing address will see the payment on invoice option? I use the module Payment on invoice from Silbersaiten. There is the possibility to deactivate the payment on invoice for different customer groups, but I can't distinguish between companies and private customers for all guest orders. For this reason, I would like payment on account to be displayed whenever a guest has entered a company name in the billing address in the order process.

Thanks for your feedback and help.
