Shopify upsells & cross-sells after WooCommerce migration: apps and setup (2026)

WooCommerce stores often use a mix of plugins for upsells and cross-sells: WooCommerce's built-in related products and upsells fields, Frequently Bought Together plugins, WooCommerce Smart Coupons, and sometimes AutomateWoo for post-purchase email sequences. After migrating to Shopify, you'll rebuild this revenue layer using Shopify apps. Here's the full setup guide.

WooCommerce upsell/cross-sell features to replace

WooCommerce had built-in upsell and cross-sell functionality:

• Upsell products: Set in product edit → "Linked Products" → Upsells. Displays on the product page ("You may also like").
• Cross-sell products: Set in product edit → "Linked Products" → Cross-sells. Displays in the cart sidebar.
• Related products: Auto-generated from same category and tags. No manual curation needed.
• Product recommendations section: Native WooCommerce theme sections.
• Plugins: Frequently Bought Together: WooCommerce Frequently Bought Together, YITH WooCommerce Frequently Bought Together.
• Plugins: CartFlows, WooFunnels: Full funnel builder with checkout upsells and order bumps.
• Plugins: AutomateWoo: Post-purchase cross-sell email sequences.

Shopify upsell/cross-sell touchpoints

In Shopify, there are multiple places to implement upsells and cross-sells:

1. Product page — "Frequently bought together"

Show complementary products alongside the main product before adding to cart.

2. Cart — cross-sell recommendation

Show products that complement what's in the cart.

3. Cart upsell / order bump

Offer a higher-value version of the product in the cart, or add a related product at a discounted rate.

4. Post-purchase upsell

After checkout confirmation — offer an additional product that can be added to the existing order with one click (no re-entering payment details).

5. Thank-you page cross-sell

On the order confirmation page, suggest products for the next purchase.

6. Email post-purchase sequence

Automated email 3–7 days after purchase suggesting complementary products.

Native Shopify product recommendations

Shopify themes include a "Related products" or "You may also like" section on product pages:

• Default: Shopify's AI product recommendations (based on purchase history and similar products)
• Manual: Use Shopify's Complementary Products feature (Shopify Search & Discovery app)
• In Shopify Admin → Apps → Search & Discovery → Recommendations: set manual product recommendations per product
• Or: set recommendations via metafield (list.product_reference) for full manual control

Migrating WooCommerce upsell/cross-sell relationships

WooCommerce stores have manually-curated upsell and cross-sell product relationships. Export and migrate these:

1. Export WooCommerce products with upsell IDs and cross-sell IDs using WooCommerce CSV export (includes upsell_ids and crosssell_ids columns)
2. Map WooCommerce product IDs to Shopify product IDs (or handles)
3. Set Shopify complementary product recommendations via the Search & Discovery app (manual) or API
4. For large catalogs: use Shopify Admin API productRecommendationUpdate or a custom script to bulk-set complementary products from the WooCommerce export data

Post-purchase email cross-sell (Klaviyo/Omnisend)

If using AutomateWoo for post-purchase cross-sell emails on WooCommerce:

• Map to Klaviyo "Post-Purchase" flow: Trigger: "Ordered product" event. Wait 7 days. Send: "Customers who bought X also bought Y" email with cross-sell recommendations.
• Klaviyo product recommendations block: In email designer, use the Product Recommendations block — AI-powered personalized product suggestions based on purchase history
• Segmented post-purchase flows: Branch by product category purchased — customers who bought footwear get accessories email; customers who bought skincare get complementary products

Cart abandonment upsell opportunity

Cart abandonment emails often include a product recommendation alongside the abandoned items:

• In Klaviyo abandoned cart flow: add a "recommended products" block after the abandoned cart items
• Recommend: "Customers who bought [abandoned product] often pair it with [complementary product]"
• This turns a re-engagement email into an upsell opportunity

Upsell strategy: what to offer where

Touchpoint	Best offer type	Average uplift
Product page ("FBT")	Complementary add-on (e.g., accessories to product)	1–3% of product page visitors add FBT item
Cart cross-sell	Low-cost item related to cart contents ($10–$30)	3–8% of checkout starts
Post-purchase upsell	Upgraded version or complementary product (one-click)	5–15% conversion on offer
Thank-you page	Related product for next purchase or loyalty offer	1–5% immediate add
Post-purchase email (day 7)	Refill or complementary product	2–8% email open-to-purchase

Upsell migration checklist

• Export WooCommerce cross-sell and upsell product relationships (upsell_ids, crosssell_ids columns)
• Install Shopify Search & Discovery app (free) and configure complementary products
• Install ReConvert or AfterSell for post-purchase upsell
• Configure post-purchase upsell trigger: what product triggers what upsell offer
• Install Frequently Bought Together for product page bundle offers
• Set up cart cross-sell (Zoorix or in-cart upsell app, or native theme)
• Rebuild AutomateWoo cross-sell flows as Klaviyo/Omnisend post-purchase email flows
• Test full upsell funnel: add product → cart cross-sell → checkout → post-purchase upsell → thank-you
• Set AOV (average order value) baseline before enabling upsells → compare 30 days after

Post-purchase upsell is the highest-priority upsell implementation after migration — it works even before you've optimized product page recommendations and doesn't interfere with the checkout flow. Start with ReConvert configured to offer a single relevant product after purchase. Measure uplift over 30 days, then add more sophisticated upsell points once the baseline is established.
