🎯 Overview
Rebuy’s Checkout + Post-Purchase suite helps you get more from the highest-intent stages of the customer journey. From relevant checkout recommendations to one-click post-purchase upsells and downsells, these features give you opportunities to increase order value, improve conversion, generate incremental revenue, and encourage future purchases—all while keeping the core buying experience focused and easy to navigate.
A strong default strategy is to first launch a simple post-purchase experience, then use A/B testing to identify your highest-performing offers, and finally optimize checkout with relevant recommendations and conversion-focused content. Rebuy’s post-purchase offers can add accepted products to the original order without requiring customers to re-enter payment information.
By implementing the plays below, you’ll establish a strong Checkout + Post-Purchase foundation that can support AOV, Conversion Rate, Revenue Per Visitor, LTV, and ROAS.
🛍️ 1. Launch Post-Purchase Upsells + Downsells
Post-purchase is one of the easiest places to start because it creates an additional revenue opportunity after the customer has completed the initial checkout. Rebuy lets you build post-purchase widgets and flows that can include both upsells and downsells.
Common KPI Impact:
AOV • RPV • ROAS • LTV
Start With a Relevant Upsell: Recommend an accessory, complementary product, replenishable item, or other logical addition based on the customer’s original order.
Add a Downsell: If the shopper declines the initial upsell, give them another relevant option at a different product or price point.
Build a Post-Purchase Flow: Determine what customers see based on whether they accept or decline each offer.
Enable Rebuy in Shopify: Once the widget and flow are ready, Rebuy must be selected as your post-purchase provider in Shopify Checkout settings.
Pro Tip: Start simple. Launch one highly relevant upsell and one downsell before building more complicated sequences. Once you have baseline performance data, use testing to determine where additional offers actually improve revenue.

📊 2. A/B Test Your Post-Purchase Offers
Once your baseline post-purchase experience is live, use Rebuy’s A/B Testing tools to understand what your customers actually respond to. Rebuy supports A/B testing of post-purchase widgets and describes the capability as a way to identify the combination of offers that produces the strongest ROI.
Common KPI Impact:
AOV • RPV • ROAS • Conversion of Post-Purchase Offers
Test Different Products: Compare accessories, best sellers, complementary items, or other logical recommendations.
Test Discounts: Experiment with different incentive levels to understand whether the additional conversion justifies the discount.
Test Language: Compare headlines, calls to action, urgency, product benefits, or value-oriented messaging.
Test Upsell + Downsell Sequences: Try different combinations and ordering to find the flow that generates the strongest incremental revenue.
Use the Results to Scale Winners: Once you identify a better-performing experience, use those learnings across additional post-purchase flows.
Resources:
Pro Tip: Don’t optimize only for offer acceptance rate. Look at revenue generated by the overall experience. A higher-priced offer may convert less frequently but still generate more incremental revenue.
🛒 3. Optimize Checkout to Improve Conversion + Order Value
For Shopify Plus merchants, Rebuy Checkout Extensions can place product recommendations directly inside checkout. Non-Plus merchants can still use supported Rebuy content on the Thank You and Order Status Pages, but in-checkout recommendations and add-ons are exclusive to Shopify Plus.
Common KPI Impact:
Conversion Rate • AOV • RPV • ROAS
Add Relevant Product Recommendations: Surface products that naturally complement what the shopper is already purchasing.
Reduce Purchase Hesitation: Use supported Checkout Content Blocks for trust-building messaging, promotional content, or other information that helps customers confidently finish checkout.
Use Checkout Best Practices: Rebuy recommends tactics such as clear pricing, mystery gifts, free-shipping bumps, subscription cross-sells, trust badges, and checkout experimentation.
Test Checkout Recommendations: Eligible merchants can compare checkout offers and recommendations using Rebuy’s checkout A/B testing capabilities.
Pro Tip: Keep checkout focused. The best checkout upsells feel like a natural extension of the existing order rather than another shopping experience.
⚠️ Important: URL Rules Are Not Supported in Checkout or Post-Purchase
URL Parameters are currently listed as an unsupported Data Source rule for Rebuy Checkout Extensions, and URL-Based Rules are not supported in Post-Purchase.
If you want to personalize experiences using UTM parameters or traffic source, use those rules earlier in the journey through Cart + Merchandising or Smart Flows rather than building that strategy directly in checkout or post-purchase.
📈 Additional Strategies & Use Cases
Create a Mystery Gift Offer
Mystery Gifts can add an element of surprise to checkout while creating another revenue opportunity. Rebuy’s Checkout Mystery Gift strategy supports creating a mystery product, configuring its presentation, and even tagging customers who purchase it for future marketing.
Helps With:
AOV • RPV • LTV
Key Actions:
Choose the Mystery Product: Use a product that provides compelling perceived value while maintaining healthy economics.
Create the Offer in Checkout: Present the mystery item as an optional addition to the customer’s order.
Use Scarcity Carefully: If inventory is genuinely limited, that can become part of the offer positioning.
Tag Purchasers for Future Campaigns: Build a segment of mystery gift purchasers and use that information for future merchandising or retention strategies.
Resources:
Offer a Discounted Gift Card Post-Purchase
A discounted gift card can generate revenue on the current transaction while also giving the customer a reason to return for another purchase. Rebuy specifically recommends discounted future gift cards as a post-purchase LTV strategy.
Helps With:
LTV • AOV • RPV
Key Actions:
Create a Gift Card Product: Choose the gift card value you want to promote.
Add a Post-Purchase Incentive: Offer the gift card at a discount after the initial purchase.
Test the Economics: Experiment with different gift card amounts and discounts.
Position It Around the Next Purchase: Clearly communicate how the customer can use the value when they return.
Resources:
Use Samples to Encourage Product Discovery
Samples can introduce shoppers to new products or categories while giving you a natural opportunity for future retargeting. Rebuy’s ecommerce use cases recommend samples at checkout as a way to drive cross-category discovery and follow-up purchases.
Helps With:
LTV • AOV • Product Discovery
Key Actions:
Choose Strategic Samples: Prioritize products that have a clear full-size purchase opportunity later.
Offer Samples in Checkout: Use a checkout recommendation where available and appropriate.
Track Sample Purchasers: Segment customers who receive or purchase samples.
Follow Up With the Full-Size Product: Use your marketing tools to introduce the full-size version after the customer has had time to try the sample.
Resources:
Bump Customers Above the Free Shipping Threshold
If a customer is close to qualifying for free shipping, use checkout recommendations to make it easy to add one more relevant product. Rebuy’s dedicated Bump Above Free Shipping strategy is designed to increase revenue while helping remove shipping-related friction.
Helps With:
AOV • Conversion Rate • RPV
Key Actions:
Identify Your Free Shipping Threshold: Start with your existing store policy.
Understand the Typical Gap: Determine how far below the threshold customers commonly are at checkout.
Recommend a Product Near That Value: Give customers a simple way to cross the threshold with one click.
Keep the Product Relevant: Recommend an item that makes sense alongside their existing purchase.
Measure Both Revenue + Conversion: Evaluate whether the offer increases cart value while helping customers complete their order.

Once your Checkout + Post-Purchase foundation is live, expand your strategy across the rest of the customer journey:

Smart Flows + A/B Testing: Use Rebuy’s no-code Smart Flows editor to create personalized, conditional storefront experiences and combine those journeys with experimentation. Smart Flows and A/B Testing are currently part of Rebuy’s Flows & A/B Testing package or Enterprise.
