How to Set Up One‑Click Post‑Purchase Upsells with AfterSell (Step‑by‑Step Guide)

Install and Connect AfterSell

Start by going to the AfterSell listing in the Shopify App Store and clicking Add App. Shopify will prompt you to review the permissions AfterSell requires — these include read access to orders and products, and write access to checkout extensions and the thank-you page.

All of these are required for AfterSell to place and track upsell offers.

After granting permissions, Shopify redirects you to the AfterSell dashboard. The app is now installed and connected to your store. Your 30-day free trial starts immediately, no credit card required during the trial period.

Set Up Your First Funnel

In the AfterSell dashboard, click Funnels in the left sidebar, then click Create Funnel. AfterSell will ask what type of funnel you want to create:

• Post-Purchase Upsell — appears between checkout confirmation and thank-you page. This is what most stores should start with. Available to all Shopify plans.
• Thank-You Page Upsell — appears on the thank-you page itself. Slightly lower conversion rates but more flexible in design. Good for standard Shopify plans.
• Native Checkout Post-Purchase — available to Shopify Plus only. The most seamless experience — appears directly in Shopify's native checkout flow.

Select Post-Purchase Upsell and give your funnel a descriptive name; something that identifies the trigger product and the upsell product so you can manage multiple funnels later without confusion. For example: "Running Shoes → Workout Socks Upsell".

Build the Upsell Offer Using the Drag-and-Drop Editor

AfterSell's offer editor is visual and does not require any code. Here is what you are configuring and why each element matters:

• Product selection: Choose the product you want to offer as an upsell. This should be directly related to what the customer just bought — the closer the relevance, the higher the conversion rate. Avoid choosing your most popular product in general; choose the product most complementary to the trigger item.
• Discount: Apply a percentage or flat dollar discount exclusive to the post-purchase upsell. The discount is the key conversion driver — customers accept the offer because they are getting something they already wanted at a price they would not get otherwise. A 10–25% discount typically produces the best conversion-to-margin balance.
• Headline and body copy: Write copy that builds on the buying momentum. Avoid generic language like "You Might Also Like." Instead, write something specific: "Your order is confirmed — add [Product] to your package in one click and save 20%."
• Product images: Use lifestyle images if available — show the upsell product in use alongside the item they just bought. Lifestyle context increases perceived value and conversion rate.
• Video: AfterSell supports embedding a short video demonstrating the upsell product. For products that benefit from demonstration (gadgets, fitness tools, beauty devices), a 20–30 second video can meaningfully increase conversion rate.
• Countdown timer: Adding a timer creates urgency. Keep the countdown realistic — 10 to 15 minutes is enough to create genuine urgency without feeling manipulative.
• Accept/Decline button text: Customise both buttons. The accept button should reinforce value: "Yes, Add to My Order." The decline button should not create shame: "No thanks, I'm happy with my order" is better than "Skip this offer."

Transform the Thank-You Page Into a Revenue Asset

AfterSell's thank-you page editor lets you completely redesign Shopify's default order confirmation page. Most Shopify stores treat the thank-you page as a dead end — AfterSell turns it into a continuation of the customer relationship.

• Order summary block: Show customers exactly what they ordered with clean visual confirmation
• Review request block: AfterSell integrates with Stamped.io, Okendo, Loox, and Yotpo — automatically trigger a review request on the thank-you page while the purchase is fresh
• Social sharing block: Prompt customers to share their purchase on Instagram or TikTok with a custom hashtag
• Cross-sell block: Display a curated selection of related products (distinct from the one-click upsell — these are clickable product links that take customers back to your store)
• Loyalty programme block: If you run a points programme, show customers the points they just earned and how close they are to their next reward
• Referral block: Offer customers a unique discount code to share with friends — turning every buyer into a potential acquisition channel

The thank-you page is the last branded moment before the customer leaves your store.

A well-designed AfterSell thank-you page creates goodwill, generates reviews, and often produces additional purchases from customers who did not accept the post-purchase upsell but are still browsing the product recommendations.

Define Who Sees Which Offer

A generic upsell shown to every customer converts poorly. AfterSell's targeting rules let you match the right offer to the right buyer based on what they actually purchased and who they are.

• Trigger product: Show this upsell only when the customer purchased a specific product or product variant. The most important targeting rule — always define the trigger.
• Trigger collection: Show the upsell when any product from a specific collection was purchased. Useful for stores with many products in a single category.
• Minimum cart value: Only show premium upsells to customers whose cart value meets a threshold (e.g., only show a $60 upsell if the cart total was over $100).
• Customer tags: Show different offers to returning customers versus new customers. First-time buyers might see a starter bundle; repeat customers might see a premium upgrade.
• UTM parameters: Match the upsell to the original traffic source. Customers arriving via a Facebook ad campaign might respond to a different offer than those arriving from email or organic search.
• Country / location: Show different upsells based on the customer's shipping country — relevant for stores with inventory in specific warehouses or products specific to certain markets.

Capture Customers Who Decline the Main Upsell

A downsell is a second offer shown to customers who declined your primary upsell. It is the difference between a lost opportunity and a recovered partial sale. AfterSell makes downsells a single additional step in the funnel builder.

Effective downsell structure: if your primary upsell is a $45 product at 20% off, your downsell might be a $15 to $20 complementary item at full price, or a smaller quantity of the same product. The downsell should feel like a natural step down — not a second attempt at the same pitch.

• In the funnel editor, click Add Step → Downsell after your primary upsell step
• Select a lower-price complementary product
• Adjust the copy to acknowledge the decline: "No problem — we thought you might prefer this instead"
• Keep the downsell offer simple and fast — the customer has already said no once

Test Your Way to Higher Conversion Rates

AfterSell's built-in A/B testing lets you run two variants of the same offer simultaneously, with AfterSell splitting traffic equally between them and tracking which version converts better. This is the most underused feature in most AfterSell setups — and the one with the highest potential ROI.

Start by testing one variable at a time. The highest-impact elements to test first:

In AfterSell's funnel editor, click Create A/B Test, duplicate your current offer as the control, and modify the single variable you want to test. Let each variant accumulate at least 100 to 200 upsell offer views before making a judgement call — smaller sample sizes produce unreliable results.

Go Live and Verify Everything Works

Before sending real customer traffic through your funnel, test the full experience yourself:

• In AfterSell's dashboard, click Preview on your funnel to see a static preview of how the offer will appear
• Place a real test order on your store for the trigger product using Shopify's test payment mode or a real small-value purchase
• Verify the upsell offer appears immediately after the checkout confirmation screen — before the thank-you page
• Click Accept Offer and confirm the upsell product is added to the order correctly in your Shopify admin
• Decline the offer and confirm the downsell appears (if configured)
• Verify the thank-you page displays correctly with all configured blocks
• Check that the completed order shows correctly in AfterSell's analytics dashboard

Once everything checks out, toggle your funnel to Active. The funnel is now live and will trigger for every customer who purchases the specified trigger product.

Use Your Data to Optimise Continuously

AfterSell's analytics dashboard shows you the metrics that matter for evaluating and improving your funnels:

• Upsell views: How many customers saw your post-purchase offer — this is your exposure count
• Acceptance rate: The percentage of customers who accepted the upsell. Industry benchmarks range from 5% to 20% depending on offer relevance and price
• Revenue generated: Total incremental revenue produced by each funnel
• Average order value lift: The difference in AOV between customers who went through the funnel and those who did not
• A/B test results: Side-by-side conversion rate comparison for each variant
• Top converting products: Which upsell products are accepting the highest rate

The primary metric to optimise is acceptance rate. A rate below 5% indicates a mismatch between the trigger product and the upsell offer, a price point that feels too high, or copy that is not connecting. A rate above 15% is strong — focus on scaling volume rather than further optimising conversion.
