B2B wholesale order management on Shopify: setting purchase minimums and case packs

Wholesale is different from retail. Your B2B customers order in dozens, cases, or pallets. Letting them buy single units defeats the purpose of a wholesale channel.

Shopify has native B2B features for Plus merchants, including quantity rules. But if you’re on a standard plan, or you need more flexibility than the native tools provide, you’ll need another approach.

This guide covers how to set purchase minimums and case pack requirements for wholesale orders on Shopify.

What wholesale customers expect

Wholesale buyers are used to minimums. They expect:

• Minimum order quantities (buy at least 12 units)
• Case pack ordering (buy in multiples of 6)
• Minimum order values ($500 to open an account or place an order)
• Tiered pricing (better rates at higher volumes)

If your store doesn’t enforce these, you’ll get small orders that aren’t worth fulfilling at wholesale prices. A buyer orders 3 units at your wholesale rate, and you’ve just lost money on the transaction.

Shopify’s native B2B quantity rules

Shopify Plus includes B2B features with quantity rules. You can set:

• Minimum order quantity per product
• Maximum order quantity per product
• Quantity increments (multiples of X)

These rules only apply to customers set up as B2B company contacts in your wholesale channel. They don’t affect regular retail customers.

If you’re on Shopify Plus and primarily selling to registered B2B accounts, the native tools handle basic minimums and increments.

The limitations: native rules are product-specific. You can’t easily set a store-wide minimum order value, and you can’t apply different rules to different customer segments within your B2B channel.

Setting minimums for non-Plus stores

If you’re not on Shopify Plus, or you need features beyond native capabilities, DC Order Limits fills the gap.

Minimum order quantity. Require customers to add at least X units before checkout. Set this globally or per product.

In DC Order Limits:

1. Create a new Quantity and Price Limit rule
2. Set the minimum quantity (say, 12)
3. Apply it to your wholesale products using tags
4. Tag your wholesale products with “wholesale” and target that tag

Customers see an error if they try to check out with fewer than 12 units.

Quantity increments. Require orders in multiples (cases of 6, packs of 12).

In DC Order Limits:

1. Create a rule and set allowed quantities
2. Enter the specific quantities customers can order: 6, 12, 18, 24, etc.
3. Apply to products that ship in case packs

A customer trying to order 7 units sees a message that they need to order in multiples of 6.

Minimum order value. Require a cart total of $500 before checkout.

In DC Order Limits:

1. Create a Quantity and Price Limit rule
2. Go to the Price Limits tab
3. Set minimum price to $500
4. Apply to wholesale products or all products

This ensures every wholesale order meets your minimum threshold for fulfillment costs and pricing.

Case pack ordering in practice

You sell beverages. Retail customers can buy individual bottles. Wholesale customers must buy by the case (24 bottles).

Set up two experiences:

1. Retail products have no minimum. Customers buy 1, 2, or however many they want.

2. Wholesale products (tagged “wholesale”) have:

   • Minimum quantity: 24
   • Quantity increments: 24, 48, 72, 96, etc.
   • Minimum order value: $200

Tag your wholesale-specific variants or products. Apply the rules to that tag. Wholesale buyers see the requirements. Retail customers don’t.

Some stores use separate product listings for wholesale. Others use the same products but different customer segments. DC Order Limits works with either approach through customer tag targeting.

Customer-specific rules

Not all wholesale customers are the same. A small retailer ordering for one store has different needs than a distributor stocking a warehouse.

You can set different rules for different customer segments:

By customer tag. Tag customers as “wholesale-small” or “wholesale-distributor” and apply different minimums to each group.

By location or market. Apply rules to specific Shopify markets if you have different requirements for different regions.

Exclusions. Exempt certain customers from minimums. Your largest accounts might have negotiated terms that don’t fit standard rules.

In DC Order Limits, customer targeting lets you specify which segments see which rules. Create multiple rules with different customer tag requirements.

Combining with Shopify B2B

If you’re on Shopify Plus with B2B enabled, you can layer DC Order Limits on top of native features.

Use native B2B for:

• Company profiles and payment terms
• Catalog visibility and product access
• Basic quantity rules per product

Use DC Order Limits for:

• Store-wide minimum order values
• Customer-segment-specific rules
• Lifetime purchase tracking
• More complex increment patterns

The two systems work independently. Native rules apply in the B2B channel. DC Order Limits rules apply at checkout for any customer segment you configure.

Common wholesale scenarios

Scenario 1: Apparel wholesaler

You sell t-shirts to boutiques. Minimum order is 2 cases (48 shirts). Each case contains 24 shirts in mixed sizes.

Rules:

• Minimum quantity: 48
• Quantity increments: 24
• Minimum order value: $400

Scenario 2: Food distributor

You sell specialty foods to restaurants. Minimum order is $750. Products ship by the case (6 or 12 units depending on product).

Rules:

• Minimum order value: $750
• Per-product quantity increments: set individually based on case size

Scenario 3: Mixed retail and wholesale

You sell to consumers and retailers from the same store. Consumers buy retail. Retailers with a “wholesale” tag get wholesale pricing and must meet minimums.

Rules (applied to “wholesale” customer tag only):

• Minimum quantity: 12 per product
• Minimum order value: $300

Retail customers see no minimums. Wholesale customers see all of them.

Getting set up

Decide your requirements:

• What’s the minimum order quantity?
• Do products ship in case packs?
• Is there a minimum order value?
• Do different customer segments have different rules?

In DC Order Limits, create rules for each requirement. Tag your wholesale products. Tag your wholesale customers. Test with a sample account before going live.

Wholesale customers expect structure. Give them clear minimums, and they’ll order accordingly.
