The least intuitive limit in the app, and the one with the clearest reasons behind it: high-value orders carry the most chargeback risk, and often need a human before they ship.
Before you start
- The value above which you want to handle an order yourself.
- Where those customers should go instead — an email address, a quote form, a phone number.
Steps
1. Install Nex Validator
Search Nex Validator in the Shopify App Store, or use the button below. Approve the permissions and the app appears in your admin under Apps. There is a free trial, and it works on every Shopify plan.
2. Go to Simple Order Limit → Create Rule.
3. Give the rule a title, and switch Enable/Disable Limit on. A rule that is saved but not enabled looks identical to one that is not working.
4. Open the Cart tab, choose Cart Max Amount, and enter your maximum cart value.
5. Write the message, then save — and put the next step in it.
Verify it worked
- Cart above the cap → checkout blocked, message shows the alternative route.
- Cart at the cap → checkout completes.
Common setups
| Goal | Maximum |
|---|---|
| Limit chargeback exposure | Your insured or comfortable ceiling |
| Route B2B enquiries to sales | Just above a normal retail basket |
| Stock-check large orders first | Whatever you can ship from shelf |
| Deposit-required orders | Your deposit threshold |
If wholesale buyers use the same storefront, this cap will hit them too. Advanced rules can exempt a tagged customer group.
