Sell B2B from the same store you sell retail. Tag a customer as wholesale and they see their own prices: a percentage off everything, off the products you pick, or off a whole collection, with quantity breaks that reward bigger orders. The product page shows each break and what it costs, worked out the way the checkout works it out, so the number a buyer reads is the number they pay. No duplicate products, no second storefront, no code in your theme.

• Customer groups are the tags you already set on customers
• Rules for everything, for chosen products, or for a collection
• Quantity breaks that reward bigger orders
• Buyers see their price and their saving before they buy
• Applied automatically at checkout, under your own label
