WooCommerce adds products to the cart and checks out. It has no built-in mechanism to suggest a complementary product, trigger a post-purchase offer, or show an order bump at checkout. Every upsell strategy in this article requires a plugin.
I tested and compared seven WooCommerce upsell plugins for 2026, evaluating each for upsell placement coverage, free tier quality, and fit for different store types. Here is what each plugin does, where the free version stops, and which stores each one fits.
What Is WooCommerce Upselling?
A WooCommerce upsell is an offer that appears after a customer has already decided to buy, prompting them to add a higher-value product, a complementary item, or a related add-on to their order.
Upsell vs. cross-sell: An upsell suggests a higher-tier version of the product being purchased. A cross-sell suggests a complementary product. Most WooCommerce upsell plugins handle both, but placement types differ.
Four placement types: Product page (shown before add-to-cart), cart (shown in the cart), checkout (shown as an order bump during checkout), and post-purchase (shown after the order is placed but before the confirmation page). Post-purchase offers convert at 5-10% because the customer has already committed. Product page suggestions convert at 1-2%.
What WooCommerce handles natively: WooCommerce lets you set “Upsells” and “Cross-sells” on individual product pages in the admin. These appear as static product suggestions below the cart. No auto-triggers, no placement control, no A/B testing. A plugin is required for anything more targeted.
These plugins were evaluated against Botiga, aThemes’ WooCommerce theme built for conversion-focused store layouts. The theme you run affects which upsell placement types perform best, and a fast theme baseline makes plugin load overhead easier to isolate.
How I Chose
- Free tier verified: I tested each plugin’s free version to confirm what it actually delivers at $0, not just what the feature page lists.
- Placement coverage: I evaluated whether each plugin covers product page, cart, checkout, and post-purchase upsell placements, or only a subset.
- Standard store compatibility: I checked compatibility with standard WooCommerce product page layouts, not just dedicated sales page builders or custom checkout flows.

Now, let’s see the six best WooCommerce upsell plugins in detail.
1. Merchant Pro: Best for All-in-One WooCommerce Upsell and Store Optimization
Merchant Pro is the top pick for stores that want multiple upsell strategies managed from one plugin without installing separate tools for each placement type.
I use Merchant Pro across aThemes stores because the upsell modules work alongside the discount and conversion modules. Running one plugin instead of four or five has a measurable effect on page load time.
Merchant Pro covers every major upsell placement type: WooCommerce upsell popups (shown after add-to-cart), frequently bought together, free gifts with purchase, BOGO deals, and post-purchase offer pages. The 45+ module library also includes storewide sale pricing, product bundles, and a floating cart with upsell slots.
Within those 45+ modules, you get multiple different tools that you can use for WooCommerce upselling:
- Trigger an upsell popup after a shopper adds an item to their cart – In this popup, you can showcase products that are related to the item the customer just added to their cart. By upselling these additional related products, you can encourage shoppers to increase the sizes of their orders.
- Display “Frequently Bought Together” products to encourage shoppers to add more items – You can also offer discounts to incentivize customers to purchase extra items.
- Create bulk discount deals and upsell them on the single product, Cart, Checkout, and Thank You pages – Shoppers can easily increase the sizes of their orders to get the bulk discount. The Thank You page option even lets you create post-purchase upsells.
- Add “Buy X, Get Y” upsells to the single product page, Cart, Checkout, and Thank You pages – You can create any type of deal and promote it in various places on your site. You can even use it as a post-purchase upsell after a shopper places their order, in addition to the other placement options.
- Add a Shopify-style slide-out side cart that includes upsells – Not only does the side cart create a great shopping experience, but you can also use it to promote related products and other upsell offers.
And again, beyond all the various upselling features, you can also access dozens of other features in a 100% modular manner. While these features span a range of different functions, you might be especially interested in the discounting features, as these can pair well with upsells. You can create various types of discounts such as storewide sales, bulk discount, buy one get one free, free gifts, product bundles, and more.
Best for: Stores that want multiple upsell placement types managed from one plugin, and stores already using Merchant Pro for discounts or other conversion features.
Not ideal if: You need a dedicated post-purchase funnel builder with multi-step flow logic. FunnelKit is more capable for that specific use case.
Price: Merchant does have a free version at WordPress.org. However, many of the upselling modules require Merchant Pro. Merchant Pro starts at $79 for use on a single site and one year of support and updates.
2. Limewoo: Best for Standalone FBT, BOGO, and Product Bundle Modules
Limewoo takes a per-module approach to upsell features. Rather than a bundled toolkit, you license individual modules – Frequently Bought Together, Buy X Get Y, Product Bundles, Free Gifts separately, paying only for the plugins your store needs.
The suite is positioned for established WooCommerce stores doing meaningful monthly revenue where every percentage point of AOV improvement compounds into significant additional income.
The per-plugin pricing model suits stores that need one or two specific upsell features and don’t want to pay for an all-in-one toolkit. A store that only needs FBT pays for that plugin alone.
Each Limewoo plugin is purpose-built for its feature type. The Frequently Bought Together module shows related product bundles on the product page with a combined pricing display. Buy X Get Y handles BOGO and threshold-based free product offers at checkout. Product Bundles lets you group products into discounted sets.
Best for: Stores that need one or two specific upsell features and for established online stores prefer per-plugin pricing over a full toolkit subscription.
Not ideal if: You just started your store with not enough traffic or meaningful revenue. You need multiple upsell placement types.
Pricing: No free version. From $69/year per module (verify current per-plugin pricing on Limewoo site)
3. Sales Booster for WooCommerce: Best for Post-Purchase Cross-Sells via Email
Sales Booster for WooCommerce from IconicWP takes a different approach to post-purchase upselling. Rather than a post-checkout page offer, it delivers product recommendations through follow-up emails after the order is confirmed.
The email-based approach means upsell offers land when the customer is already satisfied with their purchase, not immediately after they have just handed over payment. The plugin integrates with WooCommerce’s email system and lets you configure time delays, product targeting, and discount incentives for the cross-sell offer.
Sales Booster also includes on-site order bump placements at checkout, so it covers both the checkout and post-purchase email stages.
Best for: Stores with a strong email list and repeat-purchase products, where a follow-up offer after delivery converts better than a post-checkout page.
Not ideal if: You need a free tier. Sales Booster is premium-only from $79/year. UpsellWP covers post-purchase offers with a genuine free tier.
Pricing: No free version · Sales Booster from $79/year (verify current pricing)
4. UpsellWP: Best for Post-Purchase Upsells with A/B Testing (Free Option)
UpsellWP is the strongest free option on this list for stores that want post-purchase upsell offers. The free version includes a one-click post-purchase upsell page that appears after the order is placed.
The free tier also includes A/B testing for upsell offers, which is rare at no cost. You can run two versions of an upsell offer simultaneously and let the plugin identify the higher-converting variation.
Paid tiers add cart upsells, checkout order bumps, and a wider range of trigger conditions. The free version is limited to post-purchase placements and basic rule conditions.
Best for: Stores looking for a free starting point for post-purchase upsells, and stores that want A/B testing built in without a premium plan.
Not ideal if: You need cart or checkout upsells on the free tier, or if you want all upsell placements managed from one plugin that also covers discounts and conversion features.
Pricing: Free version available. UpsellWP Pro from $69/year (verify current pricing)
5. YITH WooCommerce Frequently Bought Together: Best for Product Page Bundle Suggestions
YITH WooCommerce Frequently Bought Together adds a “customers also bought” product bundle section to the single product page, showing related items the customer can add to their cart in one click.
The plugin focuses on one placement type: product page bundles before the add-to-cart button. This makes it purpose-built for stores whose upsell strategy centers on complementary product suggestions at the point of product discovery, not at checkout or post-purchase.
YITH lets you configure which products appear as bundle suggestions per product, set a combined discount for buying the bundle, and display the total price for all items. The display is clean and customizable to match your store design.
Best for: Stores that sell products with natural complements and want a dedicated frequently bought together display on the product page.
Not ideal if: You need upsell placements beyond the single product page. YITH covers product page cross-sells only. Merchant Pro includes a frequently bought together module as part of its broader upsell suite.
Pricing: No free version. EUR 79.99/year (verify current pricing)
6. FunnelKit: Best for Checkout Funnel Flows and Sales Pages
FunnelKit (formerly WooFunnels) is the most capable checkout funnel builder on this list. It replaces the default WooCommerce checkout with a multi-step funnel: a dedicated sales page, an optimized checkout page, an order bump at payment, and a post-purchase upsell page.
The post-purchase one-click upsell is FunnelKit’s strongest feature. After the customer completes their order, FunnelKit shows a dedicated upsell page where they can add a product to their existing order with one click, no re-entering payment details. This is the same mechanism that drives most high-converting direct-response stores.
FunnelKit also includes A/B split testing for funnel steps, automation sequences via FunnelKit Automations, and a growing library of pre-built funnel templates.
Best for: Stores that want to replace the default WooCommerce checkout with a dedicated conversion-optimized funnel, with multi-step upsell flows and post-purchase one-click offers.
Not ideal if: You use a standard WooCommerce product page layout and want upsells that integrate with it rather than replacing it. FunnelKit is built for dedicated sales page flows, not for stores that rely on the default WooCommerce checkout experience.
Pricing: Limited free version available. FunnelKit from $129/year (verify current pricing)
Frequently Asked Questions
The best WooCommerce upsell plugin for most stores is Merchant Pro. It covers every major upsell placement type, including upsell popups, frequently bought together, post-purchase offers, and order bumps, in one plugin. For stores focused on checkout funnel optimization with multi-step flows, FunnelKit is the strongest dedicated option. Limewoo is the best paid starting point for post-purchase upsells.
WooCommerce includes a basic Upsells and Cross-sells field on each product that shows related products below the cart. This is static and not configurable for placement timing, trigger rules, or post-purchase offers. A dedicated plugin is required for any upsell strategy more targeted than default product suggestions.
An upsell in WooCommerce suggests a higher-tier or more expensive version of the product being viewed or purchased. A cross-sell suggests a complementary product that goes well with the current purchase. Most WooCommerce upsell plugins handle both, but the placement type varies. Frequently bought together (product page) is typically cross-selling. Post-purchase one-click offers are typically upselling.
WooCommerce does not support targeted upsell placements natively, so a plugin is required. With Merchant Pro, activate the Upsell Popup or Frequently Bought Together module, configure your trigger conditions and product selections, and the offer appears automatically. With Limewoo, create a post-purchase upsell rule, set the trigger product and offer product, and the plugin displays the offer after checkout completes. Both apply the upsell without requiring the customer to re-enter payment information.
Yes. UpsellWP has a free version at WordPress.org that includes post-purchase upsell offers. FunnelKit has a limited free version, along with YITH Frequently Bought Together. Sales Booster and Limewoo are premium-only with no free tier.
