🧮 Make Your Products Purchasable in Quantity Increments

The Quantity Increment feature allows you to set fixed quantity steps for your products, meaning customers can only purchase items in multiples of a specific number — for example, 5, 10, 15, and so on.

This is especially useful for B2B or wholesale stores, where products are often packed or sold in predefined units. By enabling this feature, you can ensure that all orders follow your packaging rules, simplify inventory control, and maintain a professional wholesale experience.

⚙️ How to Enable and Configure Quantity Increments

Follow the steps below to set up Quantity Increments in your store:

🔹 Step 1: Open the “Quantity Increments” Setting

  1. From your Shopify admin, go to Apps → B2B/Wholesale Solution.

  2. In the left sidebar, select Order Management → Quantity Increments.

This section allows you to define quantity rules for specific products or collections.


🔹 Step 2: Enable Quantity Increment for a Product

  1. Click Add Rule.

  2. Under Apply to, choose whether this rule will apply to:

    • All products

    • Specific collections

    • Specific products

  3. Toggle Enable Quantity Increment to activate the rule.


🔹 Step 3: Set the Increment Value

  1. Enter the Quantity Increment Value (e.g., “5”).

    • This means customers can only order in multiples of 5 (5, 10, 15, etc.).

  2. Click Save to apply the settings.

💡 Tip: If you leave this field blank, customers can order any quantity as usual.


🔹 Step 4: Test the Rule on Your Storefront

  1. Go to your storefront and open a product that has the rule applied.

  2. Try entering a quantity that doesn’t match your set increment (e.g., “3” instead of “5”).

  3. You’ll see a message prompting the customer to adjust to the nearest valid number (e.g., “Please order in multiples of 5”).

On the product page:

  • Every time I click on the - or + button on the quantity selector, the quantity automatically jumps by 5.

  • If I try to input 22, for example, a warning message will be displayed under the Quantity box:

🧾 Example

If you sell bottled drinks in packs of 6, set your increment value to 6. Customers will then only be able to buy 6, 12, 18, and so on — keeping your orders consistent with how your products are packaged.
