# Shopify order limits: setup and scenario guides

> Configure Shopify quantity, amount, weight and customer limits. Follow practical recipes to create rules, enable checks and test storefront checkout.

Use Order Limit to control how much customers can buy and who can purchase selected products. Choose a business scenario, follow its settings, and test both allowed and blocked carts.

## Four limit types at a glance

## How the main features differ

The Chinese names below match the app sidebar. Choose a feature based on whether you need to check units, amount, weight or purchase eligibility.

| App feature | What it checks | Available settings | Example and distinction |
| - | - | - | - |
| [Quantity limits](https://order-limit.xrtotech.com/en/features/quantity.md) (**数量限制**) | Number of units purchased | Product or variant quantities; individual or combined rules; different allowances by customer tag | At least 6 of each product, or up to 3 across products. Controls how many units a customer can buy, rather than purchase eligibility |
| [Price limits](https://order-limit.xrtotech.com/en/features/price.md) (**价格限制**) | Current total amount of applicable merchandise | Minimum, maximum or amount range; different thresholds by customer tag | Require a merchandise amount of at least 100. Checks amounts without changing prices or providing discounts |
| [Weight limits](https://order-limit.xrtotech.com/en/features/weight.md) (**重量限制**) | Total applicable merchandise weight, using variant unit weight multiplied by quantity | Minimum, maximum or weight range; different thresholds by customer tag | Keep merchandise within 20 kg. Does not calculate shipping fees or split packages |
| [Customer limits](https://order-limit.xrtotech.com/en/features/customer.md) (**客户限制**) | Whether a customer can buy applicable products | Allow or block by customer tag, or require sign-in | Only VIPs can buy, or buyers must sign in. Does not set unit allowances or hide product pages |

**Cumulative customer rules** (**客户累计规则**) belong to **Quantity limits**, rather than a fifth limit type. They check repeat purchases against recorded customer quantities. Per-order and cumulative limits differ; first purchases need a separate single-order cap. See [cumulative customer rules](https://order-limit.xrtotech.com/en/features/purchase-history.md).

To let VIPs buy up to 4 units per order, use a customer-tag rule under **Quantity limits**. To let only VIPs buy, use **Customer limits**. You can combine both to control eligibility and quantity.
