jeking:
The Request Wholesale field in the admin is used to assign which pricing band the customer is assigned to, .i.e. 1, 2, 3 or 4. There is no indication on the create account page to request wholesale pricing. For my clients, I suggest they mention on their site if customers want wholesale pricing, they must contact the store owner to request it. If they 'pass', an admin will assign them to the appropriate level and email them saying so.
Hi Jim,
Thanks for your reply.
I'm not referring to the "Wholesale pricing box" which is in each separate customer's account details, and is where the level is set. That box is there, and is working correctly. I'm referring to a column in the admin Customers overview, which is headed "Request Wholesale"—see screenshot below:

I have manually created wholesaler accounts of differing levels, all of which work correctly. Nothing shows in this column though.
As you point out, there is no indication on the create account page to request wholesale pricing, but looking back through the various version history notes, there should be:

Unless this has been removed in a later version for some reason...?
