A shopper just paid, the warmest they'll be all year, and the order page says "thank you" and nothing else. Your one earlier upsell was a random "you might also like" they ignored. The best moment for a second sale, and you make no offer.
An upsell only works if it fits, and if you actually make it.
The wrong upsell is noise. No upsell at the warmest moment is money left on the table. Sledge offers the matching add-on while the shopper is still shopping and again in the cart, built from what your shoppers actually buy together, with no extra app to run it.

// The upsell that fits
"You might also like" a thing the shopper already has, or never wanted.
An upsell that ignores the cart is worse than none. They added a tent, and you suggest a different tent. They bought a coffee grinder, and you push a $400 espresso machine. Loud, irrelevant, easy to scroll past.
It fires on a generic rule with no read on what the shopper is buying, so it offers the substitute they already chose against or the upgrade ten times their budget. A mismatched offer doesn't just fail to sell. It trains shoppers to stop looking.
Sledge shows cross-sells and add-ons that fit what the shopper is buying, on the Shopify product page and in the cart drawer: the filters for the grinder, the carry bag for the tent, the matching piece for the set. The offer helps the purchase instead of interrupting it.

// The partner products they already need
They're buying the camera. They're going to need the SD card too. Did you offer it?
Some products are half a purchase on their own. The camera needs a card, the printer needs ink, the dress needs the matching shrug. Skip the companion, and the shopper forgets it or buys it elsewhere. Either way you left an easy sale on the floor.
So Sledge offers frequently-bought-together add-ons right where the shopper is buying, built from co-purchase in your own Shopify orders. Not a hunch about what pairs well, the companion product your shoppers really buy alongside it.

// The second sale after "buy"
The warmest moment in the whole journey, and the order page just says "thanks."
The instant after a shopper pays is the most willing they will ever be. The decision stress is gone, the card is already out. Post-purchase tool makers like AfterSell and Zipify report one-click thank-you-page offers lifting average order value by around 15 to 20 percent. Yet your native thank-you page does nothing with it, so you reach for another app just to put one offer there.
Same as everywhere on this page, the offer you never make is the one that costs you. So Sledge shows a post-purchase offer on the Shopify thank-you page after checkout is complete. The shopper adds it in a tap right from the confirmation page, and the offer is tied to the order they just placed, so it can't leak anywhere else. It's built into the same app as your other upsells, with no separate post-purchase app to add.

// The reward that adds itself
Your "free gift" makes the shopper hunt down the gift and add it themselves. Many won't, so they miss the deal.
That's how native discounts handle a free gift. You run "spend $75, get a free gift," and Shopify makes the shopper find the gift's page and add it themselves. Most never do. The offer that was supposed to lift their order quietly fails, and the shopper feels cheated when the "free" thing isn't in their bag.
A reward the shopper has to chase is a reward most shoppers miss. So Sledge auto-adds the free gift or reward to the Shopify cart the moment the shopper qualifies, so they never have to find and add it manually: hit the threshold, and it's already there. Want a ladder? Cart drawer progress goals stack free shipping, a discount, and a gift as separate tiers.

Questions, answered
How do I add an upsell on the Shopify thank-you page?
You create a post-purchase offer in Sledge and it renders on the order-confirmation page. Sledge's other upsells run on the product page and in the cart drawer, so the post-purchase one sits in the same app rather than a separate vendor.
Does Sledge add upsells inside Shopify checkout?
No. Checkout stays untouched. Sledge's upsells sit on the product page and in the cart drawer, before the shopper reaches checkout, and the post-purchase offer appears after the order is placed rather than inside the checkout steps.
How do I make a free gift automatically add to cart on Shopify?
Sledge auto-adds the free gift to the cart the moment a shopper hits the goal you set, a minimum quantity or a minimum purchase, so no one has to find and add it manually.
Where can Sledge show cross-sells?
On the product page, in the cart drawer, and on the thank-you page after checkout, matched to what the shopper is buying, so the offer meets them at each point they're ready to say yes.
Are the upsell suggestions based on real data?
Yes. Sledge's frequently-bought-together upsells are built from co-purchase in your own Shopify orders, so the companion product offered is one your shoppers actually buy alongside it.
Do I need a separate post-purchase upsell app with Sledge?
No. The product-page and cart cross-sells, the auto-added free gift, and the thank-you-page offer are all built in and land in the same app, so there is no separate upsell vendor to add and pay for.
How does the shopper accept the thank-you page offer?
In a tap from the confirmation page. The offer is tied to the order they just placed, and the add-on completes through checkout as its own quick order.
