Pricebook turns the customer tags you already use into wholesale price lists. Map a tag like wholesale to a pricing group, add percent-off or fixed prices with quantity breaks, preview the exact price any customer will pay, then publish. Pricing runs inside Shopify checkout as a native discount function — no scripts in your theme — and logged-in wholesale customers see their tier pricing right on the product page. Unlimited groups and rules, with no caps to outgrow.

• Map customer tags to unlimited pricing groups — no sync step, no caps
• Quantity breaks: up to 10 tiers per rule, percent off or fixed unit price
• Logged-in customers see their tier pricing right on the product page
• Runs inside Shopify checkout as a native discount — no theme scripts
