Best WooCommerce Upsell Plugins Compared (2026)

Why Upselling Is the Highest-ROI Activity in WooCommerce

Acquiring a new customer costs 5-7x more than selling to an existing one. Yet most WooCommerce stores spend 90% of their budget on acquisition and almost nothing on increasing the value of each transaction. Upselling — offering a higher-value product or add-on at the moment of purchase — is the single most efficient way to grow revenue without growing traffic.

WooCommerce doesn't include upsell funnels or order bumps natively. You get a basic "Related Products" section and a manual "Upsells" field in the product editor — but no post-purchase offers, no one-click upsells, and no A/B testing. For that, you need a plugin.

We've tested the five leading WooCommerce upsell plugins across real stores to compare features, ease of use, and actual revenue impact.

Plugin Comparison Table

1. FunnelKit (Formerly WooFunnels) — The Power User's Choice

Price: $99/year (Basic) / $179/year (Plus) / $249/year (Professional)

FunnelKit is the most complete sales funnel solution for WooCommerce. It started as WooFunnels and has evolved into a full conversion optimization platform with upsells, order bumps, checkout optimization, and automation built in.

Strengths

The one-click post-purchase upsell is FunnelKit's flagship feature. After a customer completes their order, they see a targeted offer page. One click adds it to their order — no re-entering payment details. This is the same mechanic that powers millions in revenue for Shopify stores via apps like ReConvert, and FunnelKit brings it to WooCommerce.

The funnel builder is visual and intuitive. You map out your entire sales flow: opt-in → sales page → checkout → upsell → downsell → thank you. Each step is customizable with your page builder of choice (Elementor, Divi, or the built-in editor). A/B testing is built in at every stage — test different upsell offers, pricing, or copy and let the data decide.

Analytics are detailed: conversion rates per step, revenue per funnel, A/B test results with statistical significance. You can see exactly where customers drop off and optimize accordingly.

Weaknesses

The learning curve is real. FunnelKit does a lot, and setting up your first funnel takes time. If you just want a simple order bump on checkout, this is overkill. The $99/yr base plan limits you to one site; multi-site users need the $249/yr tier. Performance can be impacted on budget hosting due to the plugin's complexity.

2. CartFlows — The Established Alternative

Price: $99/year (Starter) / $189/year (Plus) / $299/year (Pro)

CartFlows was the original WooCommerce funnel builder and remains a strong choice. It was acquired by SureCart in 2023 but continues to operate as a standalone product with active development.

Strengths

CartFlows offers a library of pre-built funnel templates that make getting started fast. Pick a template, customize it in Elementor or your preferred builder, and you have a working funnel in under an hour. One-click upsells work smoothly — the payment is charged to the same method used at checkout with no friction for the buyer.

The checkout replacement feature deserves special mention. CartFlows replaces the default WooCommerce checkout with a conversion-optimized page that includes order bumps, express checkout options, and trust badges. This alone can improve checkout conversion by 10-15%.

Dynamic offers let you set rules: if the cart contains Product A, show Upsell B. If the cart total is over $100, show a different upsell. This targeting makes upsells feel relevant rather than random.

Weaknesses

Since the SureCart acquisition, development pace has shifted. Some users report slower support response times. The Pro plan at $299/yr is expensive compared to FunnelKit's equivalent tier. The analytics dashboard, while functional, lacks the depth of FunnelKit's reporting.

3. One Click Upsell by WPFunnels — The Visual Builder

Price: $97/year (Small) / $147/year (Medium) / $237/year (Large)

WPFunnels takes a visual-first approach to funnel building. The canvas-based editor lets you map out your funnel like a flowchart, making complex multi-step sequences intuitive to design.

Strengths

The visual funnel canvas is genuinely innovative. You drag and drop funnel steps, draw connections between them, and set conditional logic visually. It's the most intuitive way to understand what happens at each stage of the customer journey. This makes it particularly good for stores with complex upsell sequences — e.g., "if they buy X and reject upsell Y, show downsell Z."

Integration with both Elementor and Gutenberg means you're not locked into a specific page builder. The one-click upsell implementation is solid and reliable, matching the core functionality of FunnelKit and CartFlows.

Weaknesses

A/B testing is more limited than FunnelKit — you can test different pages but the statistical analysis is basic. The template library is smaller. WPFunnels is a newer entrant, so the plugin has fewer reviews and less community documentation to draw from. Some advanced features require the $237/yr plan.

4. YITH WooCommerce Upsell — The Simple Approach

Price: $79/year

YITH takes a deliberately simpler approach. This isn't a funnel builder — it's an upsell and cross-sell enhancement for WooCommerce's existing checkout and product pages.

Strengths

If you don't want to build funnels and just want better upsell displays on your existing pages, YITH delivers. It adds "frequently bought together" bundles, checkout order bumps, and enhanced related product displays. Setup takes minutes, not hours. The UI is clean and matches YITH's consistent design language across their plugin family.

The "frequently bought together" feature is the standout — it mimics Amazon's bundling UX and genuinely increases basket size when configured with relevant product combinations.

Weaknesses

No one-click post-purchase upsells. No funnel building. No A/B testing. If you're looking for post-checkout offers or complex upsell sequences, YITH isn't the tool. The $79/yr price is reasonable, but you're paying a premium for what amounts to enhanced product recommendations.

5. IconicWP Sales Booster — The Lightweight Option

Price: $79/year

IconicWP Sales Booster focuses on checkout upsells and cross-sells with a lightweight, performance-conscious approach. It's designed to complement your existing checkout rather than replace it.

Strengths

Sales Booster adds cross-sell displays at checkout, "complete the look" product suggestions, and post-purchase recommendations on the thank you page. The plugin is lightweight — it won't slow down your checkout. The admin interface is minimal and fast to configure. Cross-sell rules are flexible: by product, category, tag, or global defaults.

Weaknesses

Like YITH, there are no one-click upsells, no funnel building, and no A/B testing. The thank you page recommendations are a step toward post-purchase upselling, but they require the customer to start a new checkout rather than adding to their existing order. Feature depth is limited compared to full funnel solutions.

How to Choose: Decision Framework

You need full funnel building + one-click upsells: Choose between FunnelKit and CartFlows. FunnelKit has better analytics and A/B testing. CartFlows has better templates and faster setup. Both deliver the core one-click post-purchase upsell that drives the biggest revenue gains.

You want visual funnel design: WPFunnels' canvas editor is unique and powerful. If you're a visual thinker managing complex upsell sequences, it's worth the investment.

You just want better product recommendations: YITH or IconicWP will serve you well without the complexity overhead. Both are lightweight, fast, and effective for enhancing existing product pages and checkout.

You're on a budget: Start with YITH or IconicWP at $79/yr. Upgrade to FunnelKit or CartFlows when you have enough traffic to justify A/B testing and one-click upsells — these features need volume to generate meaningful data.
