Build a B2B wholesale system where each buyer company is tagged with a tier and product-specific pricing stored as metafields. Route wholesale customers to a private portal that displays contract prices via a discount or cart function, then swap the standard checkout for a PO submission form. Route submitted orders through an approval workflow where operations staff review, adjust, and convert draft orders to confirmed sales.
Create wholesale companies in Shopify, assign them to tiers (tier 1, tier 2, etc.), and attach contract-specific prices per product without changing the public catalog.
Store per-company product pricing on each company as metafields, so one buyer sees $50 while another sees $45 for the same variant.

metafield(namespace: "wholesale", key: "company_id") { value }
}
}
}
}
# In your function logic:
# 1. Read cart.buyerIdentity.customer.metafield("wholesale", "company_id")
# 2. Fetch that company's contract prices from Shopify Admin
# 3. For each line, if a contract price exists, apply it via Cart Transform or DiscountPrivate storefront where only authenticated wholesale customers land, browse products at contract prices, and submit orders as POs instead of completing checkout.

Place this at the top of your product/collection/cart pages.
It redirects non-wholesale customers to public storefront.
