Setting up allowed quantities in Shopify with DC order limits

Allowed Quantities lets you restrict purchases to specific, fixed quantities (e.g., 2, 4, 6 — but not 1, 3, or 5). This is also called pack size limits, quantity multiples, or fixed quantity rules. Use this feature to:

Sell in pack sizes — require purchases in boxes of 6, 12, etc.
Enforce wholesale minimums — only allow orders of 10, 20, or 50 units
Control preorder batches — limit preorders to specific quantities

Unlike min/max quantity limits (which allow any number within a range), Allowed Quantities enforces an exact list of permitted values.

💡 Allowed Quantities vs. Min/Max Quantity Limits

Min/Max Quantity → Any quantity within a range (e.g., 2–10)

Allowed Quantities → Only specific values (e.g., exactly 2, 4, or 6)

If you want customers to buy "at least 2 and no more than 10," use a standard Order Limit with min/max. If you want customers to buy "exactly 2, 4, or 6," use Allowed Quantities.

When to use allowed quantities

Use this feature if you want to:

Sell products in specific pack sizes (e.g., boxes of 6 candles)
Ensure even-numbered purchases
Enforce wholesale or bulk purchasing rules
Control order volume for limited-time preorders

Setting up allowed quantities

To set up allowed quantities, follow these steps:

1. Access the Form

Go to the Order Limits page.
Click on "Create rule" and select Quantity & Price Limits.

2. Fill Out Rule Details

Rule information

Allowed quantities

Customers can only add these exact quantities to their cart. Any other quantity will show an error message. Like: "You can only purchase this product in quantities of 1, 5, or 10."

3. Configure grouping options

7. Set exclusion rules

Decide which products or customers should be excluded from this rule:

8. Save and activate

Click "Save" to apply the settings. Once saved, the rules are live immediately unless you set a future start date.

Once a rule is created, a summary of the rule's settings is displayed on the left side of the form for existing rules. This summary helps you review and confirm the rule's configurations before making further changes.
