Every WooCommerce store owner eventually faces the same challenge: traffic costs money, but conversions alone don’t tell the whole story. The real growth lever is average order value (AOV) — and that’s exactly where a well-chosen WooCommerce upsell plugin earns its keep. Whether you want to present a compelling post-purchase offer, trigger one-click add-ons inside a slide cart, or nudge customers toward a bigger spend with smart discount tiers, the right plugin can meaningfully shift your revenue per transaction without spending another cent on ads.

This guide breaks down the ten best options available today — covering their core functionality, standout strengths, and who they are best suited for. We’ve looked at what the plugins actually do under the hood, not just their marketing copy.

What Is Upselling in WooCommerce?

Upselling is the practice of encouraging a customer to purchase a more valuable item, an upgrade, a bundle, or an add-on related to what they are already buying. In an eCommerce context, it differs slightly from cross-selling (recommending entirely different products) — though many tools and strategies overlap.

WooCommerce has basic built-in upsell and cross-sell fields on product edit screens, but they are limited to simple product suggestions displayed on the single product page. They provide no control over placement timing, incentive structure, or visual presentation. That’s where dedicated WooCommerce upsell plugins come in.

Modern upsell strategies for WooCommerce typically fall into several categories:

• Pre-checkout upsells: Offers shown in the cart, slide cart drawer, or at a custom order bump step before payment.
• One-click upsells: Post-purchase offers that customers can accept or decline in a single click, after the initial payment is already processed — no re-entering payment details.
• Post-purchase upsells: Widgets displayed on the thank-you page or order confirmation screen, after the transaction is complete.
• Discount-triggered upsells: Tiered discounts, volume pricing, free shipping thresholds, and free gift incentives that encourage customers to add more to their cart.
• Bundle upsells: Frequently bought together pairings or mix-and-match bundles offered at a combined discount.

Each category serves a different moment in the buying journey, and the best upselling strategies for WooCommerce stores combine several of them.

How to Choose the Right WooCommerce Upsell Plugin

Before committing to any plugin, it helps to map your store’s needs against a few practical criteria:

• Placement flexibility: Can you show offers in the cart, on the thank-you page, in a side drawer, and via shortcodes? Or is the plugin limited to one location?
• Server-side vs. client-side discounts: Discounts applied server-side (via PHP hooks) are more reliable and harder to manipulate than those handled entirely in JavaScript.
• HPOS compatibility: If your store uses WooCommerce High-Performance Order Storage (custom order tables), the plugin must declare compatibility or you risk conflicts.
• Ease of use: A visual builder with live preview is far more practical than manually writing shortcodes or digging through settings screens.
• Pricing model: One-time purchase vs. annual subscription, and whether the price scales with traffic or sites.
• Theme compatibility: The plugin should work alongside your active theme without breaking the layout.

With those filters in mind, here are the ten best options on the market right now.

1. UpsellPress – Best All-in-One Upsell Toolkit for WooCommerce

UpsellPress (by Dominopress) is a comprehensive post-purchase upsell and modern cart plugin for WooCommerce that takes a notably different approach to most competitors. Rather than offering a single upsell mechanism, it ships with 14 distinct, fully configurable upsell widget templates — all managed through a React-powered visual builder with a live preview panel. This means you can design, customize, and deploy different upsell strategies from a single admin interface without switching between multiple plugins.

The plugin installs cleanly, requires WooCommerce to be active at all times, and immediately declares compatibility with WooCommerce HPOS (High-Performance Order Storage) and the new Cart & Checkout Blocks via the official FeaturesUtil::declare_compatibility() API — something a surprising number of upsell plugins still don’t do.

Widget Templates Available

UpsellPress includes the following upsell and cross-sell widget types, each with its own PHP handler class running on the server:

• Frequently Bought Together: Show curated product bundles that customers can add to the cart in a single action. Works well on the slide cart and at the before-checkout step.
• Advanced Free Gift: Trigger a free gift product when a customer hits a defined cart subtotal, item count, or contains a specific product. The widget displays a live progress bar. Rewards are managed server-side — no coupon codes required.
• Free Shipping Bar: A real-time progress tracker toward a free shipping threshold. Displays motivational text that updates dynamically as the cart value changes.
• Volume Discounts / Quantity Breaks: Define quantity tiers for a specific product (e.g., Buy 2 = 10% off, Buy 5 = 20% off). Discounts are applied as a negative fee via woocommerce_cart_calculate_fees, meaning they show as an itemized line in the cart — transparent and verifiable by customers.
• Smart Cross-Sell Grid: Display up to four hand-picked or automatically recommended related products in grid or list layout, each with a one-click add-to-cart button.
• Mystery Product: A gamified upsell that shows a mystery box with a crossed-out original price. The actual product is added to the cart at the discounted price, which is enforced server-side via price overrides on woocommerce_before_calculate_totals.
• Buy More, Unlock Reward: A progress-bar widget that tracks total cart item count. When the customer reaches the target, either free shipping is applied (by zeroing all shipping rates via woocommerce_package_rates) or a free product is automatically added to the cart at $0. If the customer removes items and drops below the threshold, the reward is automatically revoked — no customer-side trickery possible.
• Build Your Own Bundle: A selectable product grid where customers pick items to hit a target count and unlock a percentage discount applied server-side.
• Tiered Discount (Spend More, Save More): Escalating order-value discounts (e.g., Spend $50 = 10% off, Spend $100 = 20% off). The best qualifying tier is applied as a single negative fee. The implementation correctly uses usort to evaluate tiers in order and selects the highest applicable discount.
• One-Click Upsell: A featured product widget with pricing, discount badge, and optional social guarantee text — presented at strategic moments such as before checkout or on the thank-you page.
• Smart Recommendation: Dynamic “Customers also bought” style product suggestions based on manual selection or automated logic.
• Social Proof Upsell: Pairs a product add-to-cart offer with a configurable star rating and social proof text (e.g., “500+ customers bought this”).
• Limited Stock Alert: A scarcity-trigger widget that displays a stock warning message alongside a product to drive urgency.
• Complete the Setup: Suggests essential accessories or complementary products for items already in the cart — particularly useful for electronics or kit-based products.

Placement & Delivery

One of UpsellPress’s strongest practical advantages is its multi-placement support. Each widget can be assigned to one or more locations:

• Slide Cart (top or bottom): Widgets load inside the built-in UpsellPress side-drawer cart — so your upsell is visible exactly when the customer is reviewing their cart before purchase.
• Before Checkout: Displays on the checkout page before the customer submits payment.
• Thank You Page (before order details or inline): Post-purchase placements triggered via woocommerce_before_thankyou and woocommerce_thankyou hooks.
• After Order Table: Uses woocommerce_order_details_after_order_table to display widgets below the order summary.
• Shortcode: [upsellpress_widget placement="slug"] lets you embed any placement anywhere — useful in block editors, page builders, or custom templates.

Modern Slide Cart

UpsellPress ships with its own modern Slide Cart — a side-drawer cart drawer that replaces or augments your theme’s default cart. It’s built on the WooCommerce Store API (not legacy AJAX), which means it handles nonces correctly and stays in sync with WooCommerce’s cart state. The floating cart icon intelligently detects common chat widgets (WhatsApp, Tidio, Facebook Messenger, etc.) and shifts its position to avoid overlap — a small but thoughtful detail that shows real-world use in mind.

Technical Highlights

• All discount logic runs server-side in dedicated PHP handler classes — no client-side price manipulation.
• Full WooCommerce HPOS and Cart/Checkout Block compatibility declared via official APIs.
• React-based visual widget builder with live preview, color picker with reset, and conditional field logic.
• Duplicate widget functionality to quickly clone and adapt existing campaigns.
• Separate REST API routes for widget CRUD, activation, duplication, and bulk deletion — well-structured for a custom admin UI.
• Requires WordPress 6.0+ and WooCommerce 7.0+; tested up to WooCommerce 10.8.

2. FunnelKit (Formerly WooFunnels) – Best for Funnel-Based One-Click Upsells

FunnelKit is one of the most established names in the WordPress upsell space. Originally launched as WooFunnels, it rebranded and expanded into a full sales funnel platform. Its core strength is the one-click upsell experience — specifically, post-checkout offers that appear after the customer’s payment is captured. Because the payment is already processed, the customer can accept or reject the upsell without re-entering their billing details.

FunnelKit lets you build upsell and downsell sequences (sometimes called “offer stacks”) — present an upsell, and if the customer declines, automatically offer a cheaper alternative (a downsell). This kind of conditional branching logic makes it particularly valuable for stores with a clear product ladder.

Key Features

• True one-click upsell post-purchase flows with accept/decline branching
• Custom checkout page builder (replaces the default WooCommerce checkout)
• Order bump functionality on the checkout page
• Conversion-optimized templates included
• Integrates with Elementor, Divi, and Gutenberg
• Built-in A/B testing on funnel steps
• Works with Stripe, PayPal, and most major payment gateways

Pricing: Premium, starting around $99/year. A limited free tier is available on WordPress.org.

3. CartFlows – Best for Full Sales Funnel Design

CartFlows is another mature WooCommerce funnel builder that competes directly with FunnelKit. Where CartFlows differentiates itself is in its page-builder-first approach — it was designed from the ground up to work with Elementor, Beaver Builder, and Gutenberg, and relies heavily on those editors for designing checkout and thank-you pages.

CartFlows supports one-click upsell WooCommerce flows, order bumps at the checkout step, and A/B testing on individual funnel steps. It has a large user base and an extensive library of pre-built templates that speed up initial setup considerably.

Key Features

• Visual funnel builder with step-by-step flow management
• Pre-purchase order bumps (checkbox upsell on the checkout form)
• Post-purchase one-click upsell and downsell pages
• Custom thank-you page designer
• Dynamic offer replacement based on cart contents
• Deep integration with popular page builders
• Built-in analytics dashboard for tracking conversions per step

Pricing: Free core plugin on WordPress.org; CartFlows Pro starts at around $79/year.

4. UpStroke – Dedicated One-Click Upsell for WooCommerce

UpStroke is a standalone one-click upsell plugin produced by the same team behind WooFunnels (now FunnelKit). It focuses exclusively on one-click upsell WooCommerce offers presented immediately after a successful purchase — without the broader funnel-building infrastructure of FunnelKit itself.

The concept is straightforward: the customer completes checkout, their payment is captured, and a dedicated upsell page appears. If the customer clicks “Yes, Add to My Order,” the product is charged to the same payment method in a separate transaction. No cart re-entry. No re-authentication with PayPal or Stripe. This is the classic one-click upsell model popularized by ClickFunnels, adapted natively for WooCommerce.

Key Features

• Post-purchase, single-click acceptance without payment re-entry
• Offer sequences: upsell → downsell → second upsell, etc.
• Offer filters based on products purchased, cart total, or customer tags
• Support for variable products in upsell offers
• Requires a compatible payment gateway (Stripe, Authorize.Net, PayPal, etc.)

5. WooCommerce Boost Sales – Best Lightweight Popup Upsell

WooCommerce Boost Sales by VillaTheme is a popular, accessible option for stores that want product-page and cart popup upsells without the complexity of a full funnel plugin. It covers two core scenarios: an upsell popup triggered when a customer adds a product to their cart, and a frequently bought together section displayed below the add-to-cart button.

The plugin is considerably simpler than the funnel builders on this list, which is actually its selling point for smaller stores. Setup takes minutes. You link an upsell product to any WooCommerce product, define a popup title, and the plugin handles the rest. There’s no complex visual builder, and the styling options are limited — but for a store that just wants a basic upsell prompt, it does the job cleanly.

Key Features

• Add-to-cart trigger popup with upsell and cross-sell recommendations
• Frequently bought together display on the product page
• Quantity discount table (buy X, save Y%)
• Countdown timer for urgency
• Works out of the box with most themes

Pricing: Free version available; Pro version approximately $49 (one-time).

6. Smart Offers for WooCommerce – Best for Rule-Based Targeting

Smart Offers by StoreApps is a rule-based upsell and cross-sell plugin that takes a distinctly different approach from the visual builders in this list. Instead of a drag-and-drop UI, it uses a conditions-and-actions system: define the conditions under which an offer appears (e.g., “cart contains Product X” AND “cart total > $50”), and then define what happens (show a popup, add a product at a discount, apply a coupon, etc.).

This rule-based model makes Smart Offers highly flexible for complex targeting scenarios. You can create upsells that only fire for returning customers, that are specific to a product category, or that chain into downsells when the initial offer is rejected — all without writing code.

Key Features

• Conditional offer rules based on cart, product, customer, and order properties
• One-click accept/skip actions for quick cart additions
• Inline, popup, and notification-style offer presentations
• Support for subscription upsells via WooCommerce Subscriptions
• Offer chaining: accepted offer leads to next upsell, rejected offer leads to downsell
• Works on product pages, cart, checkout, and thank-you pages

Pricing: Starts at approximately $99/year from StoreApps.

7. YITH WooCommerce Frequently Bought Together – Best Dedicated Bundling Plugin

YITH’s Frequently Bought Together plugin is a focused, single-purpose solution that replicates the “Customers who bought this also bought” section that Amazon made famous. You manually assign companion products to each item in your catalog, and the plugin displays them on the product page as a bundled suggestion with a combined add-to-cart action.

There’s no post-purchase or cart-based upsell functionality here — this is strictly a product-page bundling upsell. But for stores where the upsell opportunity is strongest at the point of product discovery (rather than at checkout), it’s a well-executed, reliable option.

Key Features

• Product-page “frequently bought together” bundle display
• Manual product associations per item
• Optional bundle discount applied when all items are selected
• Checkbox-style item selection (customers can deselect individual items)
• Customizable position on the product page
• Compatible with variable products

Pricing: Free core version; YITH Premium Club or standalone license from approximately $69.99/year.

8. Beeketing for WooCommerce – Best for Behavioral Automation

Beeketing originally gained traction in the Shopify ecosystem before expanding to WooCommerce. It functions more like a marketing automation suite than a traditional upsell plugin — combining product recommendations, upsell popups, FOMO notifications, and email follow-up sequences in a single platform.

For upselling in WooCommerce, Beeketing’s relevant modules include Boost Sales (popup upsell at add-to-cart), Frequently Bought Together (product page bundling), and Better Coupon Box (email capture with discount incentive). Its analytics dashboard tracks revenue attributed to each automation individually, which makes it easier to identify which strategies are contributing to AOV improvement.

Key Features

• Automated product recommendation engine
• Upsell and cross-sell popups triggered by behavior
• FOMO social proof notifications (live visitor and purchase activity)
• Cart abandonment follow-up automation
• Built-in analytics per module

9. WooCommerce Product Bundles – Best for Configurable Bundle Products

Developed and sold by WooCommerce.com directly, Product Bundles is not a traditional upsell plugin — it’s a product type extension that lets you create bundled product SKUs with optional components. Think of it as a way to build configurable “build your own kit” style products that customers shop for intentionally, rather than impulse upsell prompts that appear during checkout.

Despite the distinction, Product Bundles is highly relevant to AOV strategy. By creating pre-assembled bundles at a slight discount compared to buying items individually, you incentivize customers to purchase more in a single transaction. The plugin handles inventory management per bundle component, making it suitable for stores with complex stock tracking needs.

Key Features

• Dedicated bundle product type with required and optional components
• Component-level pricing (priced individually or as a fixed bundle price)
• Stock management per component
• Optional quantities per component
• Supports virtual and downloadable products in bundles
• Works with WooCommerce Subscriptions

Pricing: Sold by WooCommerce.com at approximately $49/year. Covered by the WooCommerce.com refund policy.

10. One Click Upsell Funnel for WooCommerce – WP Swings

WP Swings (formerly Make WebBetter) publishes one of the most widely used free one-click upsell plugins on WordPress.org. It covers the core post-purchase upsell flow: after checkout, the customer sees a dedicated upsell offer page. A single click accepts the offer and adds it to their completed order.

The free version is legitimately functional for basic post-purchase upsell setups. The Pro version adds features like sandbox testing mode, multiple funnel management, advanced shortcodes for building custom offer templates, and integration with PayPal’s Reference Transactions API for one-click billing.

Key Features

• Post-purchase one-click upsell page with accept/reject navigation
• Multiple funnel creation (Pro)
• Shortcode-based offer page builder
• Global funnel rules or product-specific triggers
• Gateway compatibility with Stripe, PayPal, Authorize.Net (Pro)
• Sandbox/test mode for staging verification (Pro)

Pricing: Free core version on WordPress.org; Pro from approximately $69/year.

WooCommerce Upsell Plugin Comparison Table

Use this at-a-glance comparison to quickly match each plugin to your specific requirements. Feature support reflects the plugins’ documented capabilities as of the article publication date.

Important Considerations Before Choosing a WooCommerce Upsell Plugin

The comparison table above covers core features, but there are a few practical considerations that don’t fit neatly into a grid:

Server-Side vs. Client-Side Discount Enforcement

This is worth discussing in more depth. Several plugins in this list apply discounts purely in JavaScript — the price shown in the cart changes visually, but if the customer manipulates the request or if a JavaScript error occurs, the actual charge might not reflect the discount. Server-side enforcement (as implemented by UpsellPress via dedicated PHP handler classes like UpsellPress_Volume_Discount and UpsellPress_Tiered_Discount) means the discount is validated and applied by WordPress/WooCommerce on the server during every cart totals recalculation. This is the more reliable and secure approach, and it’s what you’d expect from production-grade eCommerce software.

HPOS and Block Checkout Compatibility

WooCommerce’s High-Performance Order Storage (HPOS) has been the default for new stores since WooCommerce 8.x. Many older plugins were written against the legacy wp_posts order storage and haven’t been updated. Before installing any upsell plugin on a store using HPOS or the new Checkout Block, verify that the plugin explicitly declares compatibility — otherwise you may face silent failures or blocked activation. UpsellPress handles this correctly at the top of its main plugin file using the FeaturesUtil::declare_compatibility() call for both HPOS and cart/checkout blocks.

Gateway Requirements for True One-Click Post-Purchase Upsells

Post-purchase one-click upsells that charge the customer’s stored payment method after checkout require the payment gateway to support off-session charges. Not every gateway does. Stripe supports this natively via Payment Intents. PayPal supports it via Reference Transactions (which must be enabled by PayPal on a per-account basis). Square and many regional gateways do not support this model. If your store runs on a gateway that doesn’t support off-session charges, you’ll need to limit your upsell strategy to cart-based and checkout-page offers rather than true post-purchase one-click billing.

Performance Impact

Every upsell plugin adds frontend JavaScript and, in many cases, additional database queries on every cart/checkout page load. If site speed is a priority (and it should be — both for conversion rates and for Core Web Vitals), look at how each plugin loads its assets. UpsellPress loads its frontend scripts only on pages that need them (checking for the presence of relevant assets before enqueueing) and uses a shared vendors bundle to avoid loading duplicate libraries. Plugins that load their full JavaScript payload site-wide, regardless of page context, are worth scrutinizing more closely.

Upselling Strategies That Actually Work in WooCommerce

Having the right plugin is only half the equation. The strategies you implement with it matter just as much. Here are the upsell approaches that tend to generate measurable results for WooCommerce stores:

1. Free Shipping Threshold

One of the oldest and most reliable tactics in eCommerce. Set your free shipping threshold slightly above your current average order value, and display a real-time progress bar (like UpsellPress’s Free Shipping Bar widget) telling the customer how much more they need to spend. The motivation to avoid paying for shipping is a powerful behavioral driver — many customers will add a low-value item purely to cross the threshold.

2. Volume Discounts for Repeat-Purchase Products

If you sell consumables — supplements, coffee, candles, cleaning products, cosmetics — quantity break pricing is extremely effective. A “Buy 2, save 10% / Buy 3, save 20%” offer at the cart or checkout stage converts well because the customer already knows they’ll use the product again, and a discount makes stocking up rational rather than impulse-driven.

3. Frequently Bought Together at the Moment of Decision

Showing related products at the product page level (YITH FBT, or UpsellPress’s Frequently Bought Together widget in the slide cart) capitalizes on the customer being in a buying mindset. Keep the bundle tight — two or three highly relevant products, not a kitchen-sink list of everything in your catalog.

4. Post-Purchase Upsells with Strong Time Relevance

The thank-you page is an underused prime real estate in most WooCommerce stores. The customer has just completed a transaction — their wallet is already out, trust has been established, and they’re in a positive emotional state. A post-purchase upsell for a complementary product (at a clear discount, with a low friction “add to order” mechanism) tends to convert better than equivalent cold traffic. Plugins like UpsellPress, FunnelKit, and CartFlows all have strong thank-you page placement support.

5. Tiered Order Discounts for High-Margin Stores

“Spend $100 to get 15% off your entire order” works particularly well for stores with high-margin products where the cost of the discount is absorbed comfortably. A real-time tier tracker in the cart (showing how close the customer is to the next saving bracket) gamifies the shopping experience in a way that encourages adding one more item.

6. Gamified and Scarcity-Based Offers

Mystery product offers (discounted but hidden until purchased) and limited stock warnings trigger urgency and curiosity — two of the most powerful purchase motivators. The key is to ensure these are genuine. A mystery product widget that always offers the same item loses its novelty quickly. A limited stock alert that never actually runs out undermines trust. Use these tactics selectively, and only when the offer or urgency is real.

Final Verdict: Which WooCommerce Upsell Plugin Should You Choose?

There’s no universal answer — the right WooCommerce upsell plugin depends on how your store acquires customers, what your product catalog looks like, and where in the buying journey the highest opportunity sits.

That said, here’s how we’d summarize the decision:

• If you want the most complete upsell toolkit in a single plugin — with cart-based incentives, post-purchase widgets, a modern slide cart, server-side discounts, and a visual builder — UpsellPress is the strongest option on this list. Its 14 widget templates cover effectively every upsell scenario, its discount logic runs server-side for reliability, and it’s built with a level of architectural care (HPOS compatibility, WooCommerce Store API integration, conditional field logic) that puts it ahead of most alternatives.
• If you want funnel-based post-purchase one-click upsell sequences with accept/decline branching and A/B testing, FunnelKit or CartFlows are the mature choices — FunnelKit if you want a self-contained platform, CartFlows if you’re already invested in Elementor or another page builder.
• If you only need post-purchase one-click billing on a budget, WP Swings One Click Upsell Funnel offers a functional free tier that most competitors don’t.
• If your upsell strategy is entirely bundle-based and focused on product page conversions, YITH FBT or WooCommerce Product Bundles cover that niche well without adding unnecessary complexity.
• If you need complex conditional rule targeting across cart, order history, and customer attributes, Smart Offers is the most flexible rule engine in this group.

Finally, a practical note: the best upsell strategy is one your customers find genuinely useful, not one that feels like a manipulative trap. Offer real value in every upsell — relevant products, honest discounts, and clear messaging. Customers who feel good about their purchase are more likely to return, and retention is ultimately where the real revenue lies.
