PriceMaster adds B2B selling tools to any Shopify store. Merchants set discount rules by percentage, fixed amount, or a fixed final amount, targeted by product, collection, or customer. Quantity break tables show volume discounts on product pages. A checkout discount function applies discounts line by line, showing the rule name on each line. Merchants can collect quote requests through a customer portal with messaging, turn accepted quotes into orders, and create manual B2B orders.

• Checkout-level discounts applied line by line via a native Shopify Function
• Quote requests with a customer portal, messaging, and one-click order creation
• Manual B2B orders with invoicing, plus a REST API for ERP and PIM integration
• Quantity break tiers and per-customer product lists for negotiated rates
