Shopify Markets vs multiple stores: how to choose
Decide whether to localise one store with Shopify Markets or run independent stores for different operations.
Read articleMinimum and maximum Shopify orders with Checkout Blocks
How to enforce an order-value rule and distinguish the validated subtotal from the money a customer ultimately pays.
Checkout Blocks can prevent an order completing when its subtotal falls outside a configured minimum or maximum. Validation is available on Basic, Grow, Advanced and Plus. Do not confuse it with access to every visual checkout customisation, which has separate requirements.
The rule uses the subtotal before gift cards or store credit are applied as payment. A customer can therefore meet a minimum order and subsequently pay a smaller amount by bank card. Decide which problem to solve before setting the amount.
Order value, free shipping and minimum quantity
| Objective | Rule type |
|---|---|
| Reject small orders | Minimum subtotal validation. |
| Reject excessively high-value orders | Maximum subtotal validation. |
| Offer free shipping above an amount | Shipping rate or shipping discount condition. |
| Sell by boxes or batches | Quantity and increment rules. |
A cart notice is not equivalent to validation preventing payment. Nor should a general value limit replace a quantity rule when the real issue is product preparation.
Create and activate validation
The official order limits guide places configuration under Apps > Checkout Blocks > Functions. Create a function, select limits validation, decide which customers it applies to and set the minimum or maximum subtotal.
- Define scope: all buyers or B2B companies only.
- Enter limits in store currency.
- Save and review the created function.
- Check status: it is initially inactive when saved.
- Activate after completing required tests and informing the team.
Limits are converted to buyers' local currency. If selling across markets, test the currencies you use and confirm the message is understandable. Do not assume another displayed currency removes validation.
A small but complete test set
| Case | Result to review |
|---|---|
| Just below the minimum | Completion is blocked and the reason is clear. |
| Exactly at the limit | Allowed if other conditions are met. |
| Above the maximum | Checkout cannot complete. |
| Discount applied | The effective subtotal evaluated and message displayed. |
| Gift card or credit | The difference between accepted subtotal and outstanding payment. |
| Accelerated payment | Validation in Shop Pay or another supported journey too. |
For example, an order with a €100 subtotal may meet a €100 minimum and leave €50 outstanding if another €50 is paid with a gift card. This illustrates behaviour; it is not a threshold recommendation for your business.
Choose a minimum without harming purchasing
Review margin, preparation, packaging and shipping for the orders you want to limit. If one category loses money but others do not, a general block may affect profitable buyers. Compare validation with pricing, batches or shipping conditions.
Communicate the minimum before the final step. If it appears only when attempting payment, buyers must rebuild the order without previously understanding the rule. Keep information consistent across product pages, cart and purchase conditions.
What to review after activation
Observe support incidents, blocked orders and abandonment in affected journeys. A maximum is not a complete fraud prevention system: a buyer may repeat transactions, and a high-value order may be legitimate. Define when to review or authorise an exception using the appropriate procedure.
If several apps validate the cart, check their conditions and messages do not conflict. Document the rule's owner and review its amount when costs or rates change. Configuration should represent a current business decision rather than become a forgotten setting.
