Can we use a different invoice style for Wholesale User Group?

Dear friends:

We have been users of Hikashop for years. One of our clients desires to expand its use of Hikashop to a "Wholesale" user group.

Until now they have been handling wholesale orders by a separate system. They see advantages (such as good invoice tracking) by user their store for both retail and wholesale sales.

As the client envisions, wholesalers can either log in and place their orders, or the client can enter the orders and ship them.

The client would (understandably we think) use a different invoice style for wholesale purchasers. We have always just used the standard order/invoice view, with some customizations.

My first question is whether having an alternative invoice style for a different user group is possible. I have looked high and low, but I cannot find an answer.

Assuming that can be done, we would likely need the help of someone with better skills than me to customize the wholesaler invoice, but the first question is the threshold question: Can a unique invoice style be used for a particular user group?

THANK YOU in advance!

Nadine at Solia.

Thank you, Nicholas. We always appreciate your support.
With kindest regards,
