What is the master catalog and how does it feed every store?

Your copy. Every supplier's offer on one listing. The Master catalog is owned, not a shared pool. One listing per garment with every supplier's offer folded in, priced live on your own account. Add products, rename them, restrict them; another network's decisions never handle yours. The buyer sees one polo. The system knows who can supply it, at what cost, on which account, and routes the blanks when the order lands. Prices are never cached; they come live from the supplier at the moment of pricing, so the number on the store is the number you pay.

What it used to cost you: A catalog you couldn't edit and a price list that was cached last quarter.

The feature is called Master catalog. It runs on the same rails as everything else here: one catalog, one price list, one cockpit, your name on the front.
