How to Limit the Maximum Order Value in Shopify | Protect High-Value Orders — plays here, or watch on YouTube.

A maximum order amount is useful when you want large orders to be reviewed before they are accepted. It can also help you manage high-value orders that need extra checks before fulfilment.

Before you start

  • Decide the maximum order value customers can place online.
  • Decide what customers should do if their order is above the maximum, such as contact you, request a quote, or call your team.

Steps

1. Install Nex Validator

If Nex Validator is not installed yet, install it from the Shopify App Store and approve the required permissions. If it is already installed, skip to the next step.

2. Go to Simple Order Limit → Create Rule.

3. Give the rule a clear title, then make sure Enable/Disable Limit is turned on. If the rule is not enabled, it will not apply to customer orders.

4. Open the Cart tab and select Cart Max Amount. Enter the maximum cart value customers are allowed to place online.

Example: if the maximum amount is 5000, a cart at 5000 is allowed, while a cart above 5000 is blocked.

5. Add a clear message that tells customers the maximum order amount and what they should do next, then save the rule. For example: “Your cart total cannot exceed 5000. For larger orders, please contact us for a quote.”

Verify it worked

  1. Create a cart above the maximum amount. Checkout should be blocked and your message should appear.
  2. Create a cart at exactly the maximum amount. Checkout should continue normally.

Test the exact maximum too. If the maximum is 5000, a cart total of exactly 5000 should be allowed. A cart above 5000 should be blocked.

Common setups

GoalExample maximum
Review very large ordersThe highest order value you want to accept automatically
Send large B2B orders to your sales teamAn amount above a normal retail order
Check stock before accepting a large orderThe highest value you can fulfil without manual review
Orders that need a deposit or quoteThe amount above which customers should contact you

If wholesale and retail customers use the same store, Advanced rules can be used to apply this limit only to specific customers or situations.

Frequently asked

Why would I refuse a large order?

Usually fraud exposure, or because big orders need a quote, a deposit or a stock check. The cap turns an automatic sale into a conversation.

What should the message say?

Give them the next step. A cap with no route forward loses the order; "For orders over £5,000 email sales@" keeps it.

Does it apply to wholesale customers too?

On the Simple builder, yes — it applies to everyone. Advanced Rules can exempt a customer group.
