Tiered Discounts Based on Variant Quantity

Shopify Discussion
,

Topic summary

A merchant with 130+ products (each having S, M, L, XL size variants) across multiple Shopify Markets catalogs seeks to implement tiered discounts based on variant quantity across products. For example: 3 items of size M from any products = 10% off, 4 items = 15% off, 5 items = 20% off, with the same logic applying independently to each size.

Key obstacles identified:

  • Shopify’s native automatic discounts cap at 100 products when targeting specific items
  • Collections cannot include individual variants, only entire products
  • Most discount apps lack variant-level quantity tracking across products or have Markets/Catalogs compatibility issues

Proposed solutions:

App recommendations: Discounty and similar apps (Hulk Discounts, Bulk Discounts Now) that support variant-level tiered discounts across entire catalogs, though Markets compatibility needs verification during trials.

Custom development: Shopify Functions or Scripts (Shopify Plus) can implement custom logic to count variant quantities by size property and apply tiered discounts, though this requires developer expertise.

Alternative approach: Use variant metafields/tags to mark sizes, then leverage discount apps supporting conditional rules based on these properties.

The discussion remains open with no confirmed resolution yet.

Hi everyone,

I’m running into a challenging limitation and hoping someone has found a workaround or solution.

My Setup

I have over 130 products, each with a “Size” variant (S, M, L, XL). I’m using Shopify Markets with multiple catalogs for different regions.

What I’m Trying to Achieve

I want to create tiered discounts based on the quantity of the same size variant added to the cart, regardless of which products they come from. For example:

  • 3 items of size M (any products) = 10% discount
  • 4 items of size M = 15% discount
  • 5 items of size M = 20% discount

The same logic should apply independently to sizes S, L, and XL.

What I’ve Tried

Native Shopify Discounts: The automatic discount feature has a 100-product limit when targeting specific products, which doesn’t cover my entire catalog.

Collections: I can’t create a collection of just “M-sized variants” because Shopify only allows adding entire products to collections, not individual variants.

Discount Apps: Most apps I’ve tested either don’t support variant-level quantity tracking across multiple products or have compatibility issues with Markets and Catalogs.

My Question

Has anyone successfully implemented variant-based tiered discounts that work across 100+ products with Markets enabled? Are there specific apps or custom solutions (Shopify Functions, Scripts, etc.) that can handle this scenario?

Any guidance would be greatly appreciated!

Hi there!:waving_hand:

I can see how managing variant-based tiered discounts across multiple catalogs can be tricky, especially with Shopify’s limitations on automatic discounts and collections.

A great solution for your scenario could be Discounty.

It allows you to set up tiered quantity-based discounts at the variant level, which means you can apply different discounts based on how many items of a specific size (S, M, L, XL) are added to the cart no matter which products they come from. Here’s how it can work for you:

  • Create Quantity Discounts by Variant: Set specific tiered discounts for each size (e.g., 10% off for 3 size M variants, 15% for 4, 20% for 5, etc.).
  • Works Across Products: You don’t need to worry about limiting the discount to specific products, as it will apply to the size variant across your entire catalog.

This app allows you to create promotions for individual variants rather than entire products, solving the issue of Shopify’s limitations with collections. Plus, it’s easy to set up and fully customizable to fit your needs.

Hope that helps!

Hi @Pablojox

Creating tiered discounts based on the quantity of the same size variant across multiple products and Shopify Markets is a challenging scenario due to variant-level tracking and Shopify’s product/collection limitations. Here is guidance based on available information and potential solutions:

Key Challenges

  • Shopify’s native automatic discounts have a 100-product limit and cannot track variant quantities across products.

  • Collections cannot target variants directly, only whole products.

  • Most discount apps either lack variant-level quantity tracking or full Markets/catalogs compatibility.

  • Shopify Scripts (Shopify Plus) and Shopify Functions offer more flexibility but require developer skills and have some variant ID limitations.

Potential Solutions

  1. Shopify Functions and Scripts (For Shopify Plus or Custom Development)

    • Shopify Scripts can implement logic that checks variant properties (like size) to apply tiered discounts per variant group.

    • Shopify Functions (newer, server-side customizable discount logic) might be adapted to count quantities per variant property, though currently they primarily operate on variant IDs.

    • Custom development is needed to aggregate quantities of variants by “Size” across products in the cart and then apply tiered discounts accordingly.

    • See examples on Shopify community and developers documentation for tiered discounts by variants.

  2. Third-party Apps Offering Variant-level Discounts

  3. Variant Tagging & Metafields + Discount Apps

    • Tag variants via metafields or tags with size info.

    • Use discount apps that support conditional discounts based on variant metafields or tags to simulate size-based discounts.

    • This approach often requires setting up custom rules and bulk tagging but can work within app capabilities.

Summary

  • The ideal approach involves using Shopify Plus with Scripts or Functions plus custom variant property logic, if accessible.

  • For non-Plus or no-code users, advanced discount apps like Hulk Discounts or Bulk Discounts Now are recommended to try for variant-focused tiered discounts.

  • Confirm app support for Shopify Markets and multiple catalogs before committing.

If desired, I can help identify specific app options or draft Script/Function logic samples tailored to your “Size” variant tiered discount requirement.
