Create a Collection Limit

Open Limits management and create a new limit

From the left-hand menu of the app, click Limits management to open the list of your rules. Click Create new order limit (or Create new limit, in the top-right, if you already have rules) to open the limit type chooser.

Choose the limit type

On the limit type chooser, find the Collection limit card and click Select.

Each Collection limit is independent — you can run several at once across different collections, each with its own conditions and date window.

Name your limit

On the General tab, enter a name in the Limit Name card. This name is for internal use only — customers will never see it. Use something descriptive like "Black Friday — max 3 from Sneakers collection" so you can audit your rules later.

Select the collection to limit

Under Select collections to limit, click the Select collection button to open the collection picker.

• Search for a collection by name.
• Tick the collection(s) you want to limit.
• Click Select to confirm.

You can pick more than one collection — the same min/max rule applies across all of them. After you confirm, the card shows how many collections are selected (for example 1 collection selected) with an Edit button to change the selection.

Set the limit conditions

Open the Limit conditions card and choose the Condition type that matches what you want to cap:

Then fill in the min/max fields. For Collection limits they appear as:

• Minimum quantity from collection / Maximum quantity from collection
• Minimum value from collection / Maximum value from collection
• matching minimum / maximum weight fields when you choose Total product weight

Important: Leave the maximum field blank to set no upper limit. Set maximum = 0 to block customers from purchasing any product in the collection.

Sell product in multiples (Total product quantity only)

Tick Sell product in multiples to force purchases in fixed bundle sizes (e.g., pairs, six-packs). When enabled, you also pick where the multiple applies via the Apply multiple to dropdown:

• Collection — total quantity from the collection must be a multiple.
• Each product — each product in the collection must be added in multiples.
• Each variant — each variant must be added in multiples.

Skip quantity values

Use Skip quantity values to block specific quantities. Enter comma-separated quantity values (e.g., 9, 18) — customers see an error if their quantity matches one of these values.

Limit different products or variants

This option lives in the Select collections to limit card (from Step 4), right under the selected collections. Tick Limit products/variants per collection when you want to cap how many different items a customer can buy from the collection, no matter the quantity of each item.

• Select Products to count each product once — several variants of the same product still count as one product.
• Select Variants to count each variant separately.
• Enter the maximum number of different products or variants allowed.

For example, with Products and a value of 4, a customer can buy any quantity of four different products from the collection. Adding a fifth different product is blocked with your limit message. Products outside the selected collection are not included in this count.

Configure Re-purchase and Advanced Setting

Below Limit conditions you'll find two more cards: Re-purchase limit and Advanced Setting. Together they control whether re-purchase rules apply, when the limit is active, and how the notification behaves.

Re-purchase limit card

Paid plan: Limit customer re-purchase is available on Basic and higher plans. On Free, this dropdown is locked to No re-purchase limit.

In the Re-purchase limit card, use the Limit customer re-purchase dropdown to cap how often a single customer can re-purchase from the collection over time:

• Once per lifetime
• Once per year
• Once per month
• No re-purchase limit
• Custom time — set your own interval in hours, days, months, or years.
• Re-purchase waiting period — after each purchase, the customer must wait a set period before buying again.

For the full breakdown of each option, see the Re-purchase limit guide.

Advanced Setting card

Active dates

• Start date — the date (GMT +00:00) the limit becomes active. Required.
• Set end date — tick this checkbox to add an end date. The limit stops applying after the end date. Leave it unchecked for an indefinite rule.

Notify about limit when

Paid plan: Notify about limit when is available on Basic and higher plans. On Free, this dropdown is locked to the default option.

Pick when the on-storefront notification should appear:

• The limit has been reached — only show the message once the limit is hit.
• "add-to-cart" button is clicked and in cart page — show whenever the customer adds to cart or changes the cart in a way that would break the limit.
• No notification — silent mode. The Checkout button is disabled when the limit is hit, but no message is shown.

"Contact us" in notification

Tick "Contact us" in notification to add a Contact us button to the limit message. When enabled, paste the destination link (live chat URL, contact form, or social channel) in the "Contact us" URL field. The button text itself is edited in the Message tab.

Customize the message and save

Switch to the Message tab to tailor the limit notification text and add translations.

• Display language — under Detect language, choose how the app picks the storefront language: Browser's language, Customer's IP, or Store language. Then choose a Backup language.
• Message and language — edit each message (minimum/maximum quantity, value, weight, and more) in the language panel. Click Add supported language to add translations; customers browsing in an unsupported language see the default language.

Use the available variables shown under Note: Here are a few variables you can use to inject the live limit values into your copy. For a Collection Limit, the available variables are:

• {{minimum_product_quantity}} / {{maximum_product_quantity}} — minimum / maximum product quantity
• {{minimum_total_product_value}} / {{maximum_total_product_value}} — minimum / maximum total value
• {{minimum_product_weight}} / {{maximum_product_weight}} — minimum / maximum product weight
• {{remaining_product_quantity}} / {{remaining_total_product_value}} / {{remaining_product_weight}} — how much more the customer can still add
• {{multiple}} — current multiple value
• {{skip_value}} — the quantity values set in Skip quantity values
• {{weight_unit}} — the shop's weight unit (lb, kg, g, oz)
• {Button text} — for the Contact us button copy

The app shows only the variables that match your chosen condition type. Click the copy icon next to any variable to put it on your clipboard.

When everything looks right, click Save at the top of the page. The limit goes live on the start date you set.

Tip: Open the collection page in an incognito tab and try to add more than the allowed quantity. Confirm the limit triggers and the message appears as expected.
