They're already buying.
Get them to buy more.

The Problem

Getting the sale is the hard part. You already did that.

Most stores obsess over conversion rate and ignore the easier win — the customer who has already decided to buy, and is deciding how much.

🛒

One item, then gone

Shoppers add a single product and check out immediately. Nothing on the page suggests there's a reason to add more.

💸

Discounts eat your margin

A flat 20% off everything trains people to wait for sales and cuts profit on orders that would have happened anyway.

🔇

Shopify keeps it quiet

A native discount doesn't show up until the shopper already qualifies for it. While they're choosing how much to buy, the offer is invisible — so they pick one item and leave.

📈

Give them a reason — and make sure they see it

Set the rule in SU-Upsell and the offer appears on the product page and in the cart, while the shopper is still deciding how much to buy — not after they've already qualified.

Promotion Rules

Four ways to grow the order

Pick the rules that fit what you sell. Run several at the same time — when more than one applies, the app shows the offer that fits best.

📦

Buy More, Save More

Per-item discounts that get better as quantity goes up. Best for consumables, refills and anything people stock up on.

Example Buy 3 or more, save 20% on every unit
💰

Spend More, Save More

Reward based on cart value instead of quantity. Works when your catalogue has a wide price range.

Example Spend $150 or more, get $20 off the order
🎟️

Coupon Code

Attach a code to a specific campaign, influencer or channel — and see exactly which one brings in orders.

Example Code SUMMER20 — 20% off orders over $80
🎁

Free Gift

Add a product to the cart automatically when a condition is met. Great for clearing slow stock or pushing new items.

Example Buy 2 items, get a travel size free

Every rule can be scheduled. Set a start and end time in your store's time zone, and the promotion runs and stops on its own — no need to remember to switch it off.

FAQ

Before you install

The questions merchants ask us most often about SU-Upsell.

No. Everything runs from inside the app. Your theme files are never modified, which means nothing breaks when you update your theme and nothing is left behind if you uninstall.
Your plan includes a set number of credits each month. Publishing a promotion costs 5 credits, and editing one that's already live costs 5 credits as well. Pausing, deleting, and keeping an existing promotion running are always free. Plan credits reset on the 1st of each month, and extra credits bought as an add-on never expire.
Every new store starts with a one-time 10 credits — enough to publish or edit two promotions before you pick a plan.
Yes. You can have several promotions running at the same time. When more than one applies to the same cart, the app shows the offer that fits best, so the customer never sees competing offers stacked on top of each other.
Yes. Set a start and end time in your store's time zone and the promotion goes live and stops on its own — useful for seasonal sales you want to set up weeks ahead.
Yes. SU-Upsell promotions run alongside Shopify discount codes. If a customer has a code that gives a better price, the better offer applies — they're never charged more than either option alone.
The app only loads on pages where a promotion is active. Pages with no active promotion are untouched, so there's nothing extra for your customers' browsers to download.
All active promotions stop running immediately. Your products, prices, orders and customer data are never modified — your store returns to exactly how it was before.
