Brand authorized-dealer portals (Winsor & Newton, DMC, Sennelier, Lion Brand), MAP enforcement?

Authorized-dealer contracts are how most premium art-supply brands gate their distribution. Winsor & Newton, Daniel Smith, Sennelier, Holbein, DMC, Lion Brand, Faber-Castell, Strathmore, Fabriano, Schmincke, each comes with MAP/MSRP enforcement, an authorized-dealer-only product feed, and (usually) quarterly compliance audits.

How Magento handles it:

• Customer-group-based pricing, same SKU exposes different prices to retail (your store) vs. wholesale (your wholesale buyers) customers.
• MAP enforcement, product attribute map_price per SKU. A cron compares your displayed price against MAP weekly; if you accidentally drop below MAP on a sale, the system either auto-corrects to MAP or flags admin for manual review. Avoids the brand calling you to terminate the contract.
• Hidden brand-portal categories, if your dealer contract says “only authorized resellers can see the discontinued-color list,” that’s a hidden category visible to a customer group only.
• Brand feed integration, many brands ship a daily/weekly product feed (colorways added/discontinued, MAP changes, MSRP updates). Winsor & Newton uses EDI; DMC uses a CSV feed; Lion Brand exposes an authorized-dealer portal API. Akeneo or Pimcore PIM as middleware keeps the catalog in sync without manual upload.
• Quarterly audit prep, admin export of “all SKUs from brand X, with current price + MAP + last-sold price” for the brand’s compliance team.

Cost: ~$3k, $8k per brand portal to wire (depending on whether they ship an API or just a CSV). Worth it if the brand is >5% of revenue, getting kicked out of authorized dealing kills that revenue overnight.
