I’m getting close to releasing Version 2 of the Wholesale Ordering plugin, which, among other things, has several hooks in place for extensions. That should be out by next week.
My next project will be to take the multi-role and user pricing system I developed for the big auto-parts store, and either package that as its own plugin, or use that as the basis for some sort of user/role based discount add-on for the wholesale ordering plugin.
I’m open to suggestions and feature requests. If I create it as an add-on for the wholesale ordering plugin, I might be able to get it out a bit faster, since a lot of the framework already exists in the wholesale ordering plugin, and I have already created the code for user/role based pricing for the auto-parts store.
If I create it as an add-on, then you could specify, per role, the base price for each role (either regular or wholesale), and a multiplier that is applied to the base price. If the user’s pricing is set at default settings, then they get whatever is set up for their role. If you specify a base price and multiplier for a specific user, then those override the role settings. For the auto-parts store, we set up 5 roles to fit their needs. If I turn it into an extension, I would probably set it up so you can specify the settings for any existing role, and maybe add something to create custom roles.
