Installing UpsellEngine and turning on the placements you want.
How do I install UpsellEngine?
Open the UpsellEngine listing on the Shopify App Store, click Add app, and approve the permissions. You land in the UpsellEngine dashboard inside your Shopify admin, and on paid plans your first AI-generated offer is typically live within about five minutes.
Install & onboardingHow do I turn on a placement?
Cart Drawer and Popup are app embeds you enable once in the Shopify theme editor. Frequently Bought Together, Product Add-ons, and the Cart Page are theme blocks you add to the relevant template. Checkout and thank-you offers are added in the checkout editor, and the one-click post-purchase offer is enabled by selecting UpsellEngine as your post-purchase app in Settings → Checkout.
Enabling placementsDo I need Shopify Plus?
Only checkout upsells require Shopify Plus, because Shopify reserves checkout customization for Plus stores. Every other placement — product page, cart, popups, post-purchase, and thank-you — works on any Shopify plan.
Checkout & post-purchase surfacesAn offer isn’t showing on my store — what should I check?
First confirm the placement’s surface is enabled (app embed or theme block), then check that the offer is published and its trigger matches the product you’re testing. On paid plans, AI recommendations may still be generating right after install or a catalog change.
Offer isn’t showingBilling
Plans, trials, invoices, and cancelling.
Do you take a percentage of my sales?
No — never, on any plan. UpsellEngine is a flat monthly fee with 0% revenue share. The upsell revenue you earn is entirely yours.
See pricingIs there a free trial?
Yes. The Starter, Growth, and Scale plans include a 14-day free trial. The Free plan is free forever, with no trial needed and no card required.
How does billing work?
Billing runs through Shopify and appears on your regular Shopify invoice alongside your other app charges — there’s no separate card, no third-party billing, and no Stripe.
Plans & billingWhat happens when I reach my monthly order limit?
Each plan includes a monthly order allowance (50, 500, 2,000, or unlimited). As you approach your limit, UpsellEngine lets you know so you can decide whether to move up a tier. You’re only ever billed your chosen plan price.
Can I cancel anytime?
Yes. There are no contracts — you can cancel or change plans at any time from Shopify, and billing stops at the end of your current period.
Offers
Creating, targeting, discounting, and testing offers.
How do I create an offer?
An offer is defined by five choices: placement, type, trigger, products, and design. In the UpsellEngine dashboard, open Offers → Create and work through each step, then publish.
Creating an offerCan I hand-pick the products in an offer?
Yes. You can let the AI recommend products or hand-pick them yourself, and you can keep specific products out of recommendations with exclusion lists.
Manual pairings & exclusionsCan I add a discount to an offer?
Yes. Discounts are optional and are applied securely at checkout — not shown as an editable price a shopper could change.
DiscountsCan I A/B test offers?
Yes. You can test product, discount, or headline variants, and UpsellEngine declares a winner automatically once a variant reaches 95% statistical confidence. A/B testing is available on the Growth plan and above.
A/B testingPost-purchase
The one-click offer after checkout, and when Shopify allows it.
Why didn’t a post-purchase offer appear on my test order?
Shopify — not the app — decides when the post-purchase page can appear. It’s skipped for wallet and pay-later methods (Apple Pay, Google Pay, Shop Pay Installments, Klarna, Afterpay, Affirm, PayPal), gift cards and non-credit-card payments, orders with no shipping address, multi-currency orders with duties, totals under $0.50, and orders created outside the Online Store channel.
When it won’t appearIs the post-purchase upsell really one click?
Yes. When Shopify allows the offer, accepting is a single click — charged to the card the shopper just used, with no re-entered payment details, and it ships with the original order.
Post-purchase upsellsCan a post-purchase offer hurt my conversion rate?
No. It appears after payment, so the original order is already complete before the offer shows. If the shopper declines, you’ve still banked the sale.
Data & privacy
What data UpsellEngine uses and how it’s handled.
What data does UpsellEngine access?
UpsellEngine reads your product catalog and order history to generate recommendations, and it creates offers and discounts on your behalf. It uses this data to power the app’s features for your store.
Do you sell my data or my customers’ data?
No. UpsellEngine does not sell your data or your customers’ data.
Is UpsellEngine GDPR-compliant?
UpsellEngine honours Shopify’s GDPR data webhooks — including customer data requests and data-redaction (erasure) requests — so you can meet your obligations for customer data.
Where can I get a data-processing summary?
A data-processing summary is available as part of our legal documentation. If you need specific details for a compliance review, contact support and we’ll help.
