What is the Upsell Builder app?
The Vitals Upsell Builder app lets you create eight types of upsell and cross-sell offers, from volume discounts to one-click post-purchase offers, to raise your average order value.
Why use Upsell Builder?
Upsell Builder raises your average order value by offering shoppers more at every step, from the product page to after payment.
Get shoppers to add more to each order with offers they can take in one click.
Apply every offer's discount at checkout automatically.
Replace separate bundle, BOGO, gift and post-purchase apps.
What types of offers can I create?
You can create eight offer types, so you can pick the offer that fits each product and each step of the order.
Give a lower price per unit when shoppers buy more.
Sell 2 to 5 products together at a bundle discount.
Give a free or discounted product when shoppers buy another.
Add a free gift once the cart reaches the amount you set.
Show a progress bar to a discount or free shipping.
Show products that go well with the one shoppers are viewing.
Let shoppers tick small extras next to Add to cart.
Offer an extra product after payment, added to the same order in one click.
Where can offers show?
You can show offers at five steps, from the product page to after payment, so shoppers see the right offer at each point.
Show offers next to Add to cart, before shoppers decide.
Offer the next tier, the bundle or the reward when shoppers add to cart.
Suggest one more product while shoppers review their cart.
Offer a missing item when shoppers click Checkout.
Offer a one-click add-on on the post-purchase page and an offer on the Thank you page.
How should I set up offers to sell more?
Turn on the Add to Cart pop-up: it got shoppers to add an offer more often than any other placement in September 2026.
Share of Add to Cart pop-up views that ended in an add-to-cart, about 12 times the product page.
Share of shoppers who accepted a one-click post-purchase offer after paying.
Orders per 1,000 views on buy X get Y offers, the second-best on-page offer type.
Can AI create an offer for me?
Yes. You can describe the offer you want, and AI picks the offer type, products, discount and text.
Type the offer you want in plain words.
Pick from a best match and a few alternatives.
Check the draft in the editor, then publish it.
Ask Claude or ChatGPT for an offer through the Vitals AI connector.
Can I choose who sees an offer and when?
Yes. You can limit each offer by date, country, customer tag and B2B status, so wholesale buyers and other markets don't get your retail deals.
Schedule the offer to start and end on the dates you pick.
Show the offer only in the markets you pick.
Hide the offer from customers with the tags you pick.
Hide the offer from wholesale customers.
Show shoppers how long is left before the offer ends.
What happens at checkout and after?
Discounts apply on their own at Shopify checkout, and every offer product is its own line on the order.
Name the discount shoppers see in the cart and at checkout.
Choose whether offers combine with your product, order and shipping discounts.
Show offer products nested under the main product in the cart.
Send accepted offers to Klaviyo and follow up after the order.
Can I make offers match my store?
Yes. You choose each offer's layout, text, colours and language, so it looks like part of your theme.
Pick a layout for each offer type, from tier bars to a gallery.
Write the offer text yourself, or let AI write it.
Click any part of the preview and style it with CSS.
