Net 30 payment terms

We have customers with an open account and net 30 terms.
Product is shipped on order, billed when shipped and customer pays subsequently.
Do you have a suggestion for how to handle this in Hikashop?
I considered using Check payment, modifying the description to reflect payment terms, but don't want to confuse existing customers with terms, or suggest that Net 30 terms are available to other customers without an open account.

Hi,

With the Business edition, you can restrict payment methods to user groups with the "access level" option of payment methods. So you could have these customers into a specific user group of joomla and restrict that check payment method to only that user group so that only them would see it.
