How it works
You pick a collection, set a minimum spend amount, and choose a discount percentage. When a customer's subtotal for items in that collection reaches the threshold, the discount applies to all items from that collection automatically.
The customer sees the savings appear at checkout as soon as they cross the threshold. No discount code needed — it just happens. And only items from the target collection count toward the threshold and receive the discount.
💰 Example: "Spend $150+ on Designer Collection, Get 15% Off"
You have a premium designer collection where items average $60-$120. You want to encourage customers to buy 2-3 pieces instead of just one. Setting a $150 threshold with a 15% discount makes that third item almost irresistible.
✓ Customer spent $180 (above $150 threshold) and saved $27.00. Without the threshold incentive, they might have only bought one piece.

Why this is better than Shopify's native options
Shopify does let you create a "minimum purchase amount" discount, but it applies to the entire cart — not a specific collection. So if you want "spend $150 on the designer collection," Shopify can't do that. A customer could buy $150 of random items and qualify, which defeats the purpose.
With Custom Promos, the spend threshold is tied to a specific collection. Only items from that collection count toward the threshold, and only those items receive the discount. This gives you laser-precise control over which products drive the promotion.
Frequently asked questions
Set a spend threshold on a collection (for example $150) and a reward percentage (for example 15% off). When the customer's spend on that collection reaches the threshold, the discount applies automatically at checkout.
It's based on spend within the collection you choose, giving you precise control. Spend on unrelated products doesn't count toward unlocking the discount.
Yes — spend thresholds are one of the most effective ways to nudge customers toward a larger order, since the reward is tied directly to how much they spend in the collection.
No. Custom Promos applies the discount automatically at checkout based on what's in the cart. There's no code for customers to remember, type, or get wrong — they simply see the savings as they shop.
Your discount codes work normally when no Custom Promos promotion is active. When a Custom Promos promotion is running, discount codes can't be stacked on top of it — this is intentional, to stop customers from combining a promotion with a separate coupon and discounting more than you planned.
Custom Promos runs on Shopify Functions, which are available on all standard Shopify plans. You don't need Shopify Plus.
Most promotions take under two minutes. You pick the promotion type, choose your collection with a visual picker, set your numbers, and activate. No code, no collection IDs, no developer.
