How to Set a Minimum Order Value in Shopify

A minimum order value protects margins when fulfillment, freight, or account-service costs make small carts uneconomical.

Define the commercial rule

Choose whether the threshold applies to all buyers, wholesale customers, a distributor tier, or first orders only. Document which subtotal is evaluated and how discounts affect the minimum.

Set a threshold based on contribution margin, handling cost, freight economics, or account policy rather than choosing an arbitrary round number.

Explain the rule before checkout

Show the required minimum and the amount remaining on the cart page or cart drawer. Clear progress feedback lets buyers fix the cart without encountering a surprise at payment.

Use direct language such as 'Add $42.50 more to reach the $250 wholesale minimum.'

Enforce at checkout

Cart messaging alone is not enforcement because buyers may reach checkout through alternate paths. A Shopify Checkout Validation Function can evaluate the active rule and block completion while the cart remains below the minimum.

Keep the cart message and checkout error consistent so the buyer understands the same requirement in both places.

Test customer contexts

• Guest and logged-in retail buyers.
• Wholesale buyers with one matching tag.
• Buyers with overlapping tags.
• Carts immediately below and above the threshold.
• Discounted carts and first-order-only rules.
