Shopify B2B Order Rules: Minimum Quantities, Maximums, and Tiers

B2B selling on Shopify requires quantity logic that standard retail does not need. Your wholesale accounts expect minimum order quantities, case pack sizes, and potentially different rules per account tier — all of which Shopify does not enforce natively.

B2B Quantity Rules Shopify Merchants Need

  • Minimum order quantity — see how to set MOQ on Shopify
  • Case pack / quantity increments — see selling in case packs
  • Maximum per customer — allocation caps for high-demand items
  • Tiered rules by account type — silver/gold/platinum tier with different minimums

Using Customer Tags for B2B Tiers

Shopify customer tags are the foundation of tag-based B2B rules. Assign tags during wholesale account approval: ‘wholesale-silver’, ‘wholesale-gold’, ‘wholesale-platinum’. Each tag gets its own Fold rule with the appropriate minimum.

Full setup for the tag-based approach: wholesale and retail quantity rules from one store.

Setting Up Tiered Minimums

Fold supports multiple simultaneous rules with tag conditions. Create:

  • Rule 1: Silver accounts — minimum 6 units per product
  • Rule 2: Gold accounts — minimum 12 units per product
  • Rule 3: Platinum accounts — minimum 24 units per product, increments of 12

Fold evaluates which rule applies based on the logged-in customer’s tag at checkout.

Combining MOQ with Minimum Order Value

Many B2B stores use both a minimum unit count and a minimum order value. Minimum order value rules in Fold enforce a basket spend floor (e.g. £500 minimum) on top of per-product quantity rules.

What About Shopify B2B (Plus)?

Shopify Plus includes native B2B features: company profiles, price lists, net payment terms. These are valuable for large-scale wholesale. For merchants on standard plans who need quantity enforcement without the Plus subscription, Fold delivers the same checkout-level control via Shopify Functions.

Frequently Asked Questions

Can I approve wholesale accounts automatically?

Tag assignment is manual by default from Shopify admin, or automated via a wholesale application form app. Fold reads whatever tags are assigned at checkout.

Do rules apply at draft order checkout?

Fold’s Functions-based rules apply at the standard Shopify checkout. Draft orders bypass standard checkout and are not subject to Functions validation.
