The Free Shipping Upsell helps customers add enough to their cart to qualify for free delivery before they pay. It works best when the goal feels close, the product suggestions are easy to understand, and the message explains the value clearly.
Use this guide when you're deciding how to set up a Free Shipping Upsell, what products to recommend, and how to test whether it's improving order value.
🔒 Shopify Plus: The Free Shipping Upsell appears on the Checkout Page and requires Shopify Plus because it uses Shopify checkout extensibility.
A free shipping threshold works best when most customers can reach it by adding one small product. If the gap feels too large, customers are more likely to continue checkout without adding anything.
As a starting point, set your threshold around 15 to 30% above your average order value. For example, if your average order value is $80, test a free shipping threshold between $92 and $104.
Threshold range | Best for | How to use it |
15 to 20% above AOV | Stores new to free shipping upsells | Use this as a safer first test when you want the goal to feel easy. |
25 to 30% above AOV | Stores with strong low-priced add-ons | Use this when you have products that naturally close the gap. |
More than 35% above AOV | Stores with deep catalogues and strong demand | Use carefully. A goal that feels too far away can reduce trust. |
💡 Tip: Start with Use global free shipping tiers so your strategy follows your saved account thresholds. Use custom thresholds only when this strategy needs different values.
The best gap-closing products are low-cost, broadly relevant, and easy to decide on. Customers shouldn't need to compare sizes, research ingredients, or think hard at checkout.
For most stores, the strongest products sit in the $5 to $30 range. Gift cards can also work well when the gap is small because they don't create a product-fit question.
Product type | Why it works | Product source to try |
Samples, minis, and travel sizes | Low commitment and easy to add. | Smart Recommendation, Group of Products, Collection |
Accessories and care items | They improve the main purchase without changing the buying decision. | Complementary Products, Related Products, Metafields |
Consumables | Customers can always use more, especially in beauty, food, pet, and supplements. | Collection, Group of Products, Smart Recommendation |
Gift cards | They can match small gaps without creating size or style friction. | Gift Card |
The Smart Gap Calculator template is the best starting point for this placement. Pair it with the Smart Recommendation product source when you want Order Editing to suggest products based on the remaining free shipping gap.
Free shipping copy should change as the customer gets closer to the threshold. A large gap needs value framing. A small gap needs simple, direct urgency.
Gap size | Copy approach | Example |
$30 or more | Focus on the reward. | Add $35 to unlock free shipping and save on delivery. |
$15 to $30 | Show progress. | You're halfway to free shipping. Add $22 more. |
$5 to $15 | Highlight proximity. | So close. Just $8 away from free shipping. |
Under $5 | Make the next step feel easy. | Only $3.50 to go. Add a small extra to unlock free shipping. |
Threshold reached | Confirm the win. | Free shipping unlocked. Your order now ships free. |
In the checkout editor, keep your copy short. Customers are already trying to complete payment, so the message should be clear at a glance.
The Placement Style controls how the Free Shipping Upsell appears in checkout. Choose the style based on how much product choice you want to give customers.
Placement Style | Best for | Recommendation |
Product Carousel | Stores with several strong low-priced add-ons. | Use when visual browsing helps customers choose quickly. |
Product List | Stores that want a compact, scannable list. | Use when checkout space is tight but product choice matters. |
Shipping Threshold Bar Only | Stores that only want to show progress. | Use when you already have strong cart add-ons elsewhere. |
Product Search | Stores with large catalogues where customers know what they want. | Use when search is more useful than curated recommendations. |
Preview the Free Shipping Upsell before making the strategy Active. Use a test cart that sits just below your threshold, then add products to confirm the progress and messaging update correctly.
After launch, review Conversion Rate, average order value, and Top Upsell Products. If customers view the placement but don't add products, test a lower-priced product group, a clearer message, or a smaller threshold gap.
⚠️ Warning: Don't add settings to your process that don't exist in Order Editing. Product selection is controlled through product sources, not a separate product-selection toggle.
