I installed 7 upsell plugins on a test WooCommerce store with 47 products across 5 categories. The setup times ranged from 3 minutes (UpsellWP) to over 45 minutes (FunnelKit with full funnel configuration). YITH’s Frequently Bought Together charged $79.99/year for a single feature that UpsellWP includes in its free version. On the other end, a completely free plugin (One Click Upsell Funnel by WPSwings) handled post-purchase upsells that most paid plugins gate behind premium tiers.
Most “best upsell plugins” articles rewrite feature lists from each plugin’s marketing page. I actually installed every plugin, timed the setup, built real upsell campaigns, and tested how the offers looked on both desktop and mobile. This article shares what I found — including which plugins are worth paying for, which ones you can skip, and how to connect upsells to a loyalty program so customers don’t just spend more once — they come back.
What Are WooCommerce Upsell Plugins?
An upsell plugin suggests higher-value or complementary products to customers during their shopping journey — on the product page, in the cart, at checkout, or after purchase. The goal: increase average order value (AOV) without acquiring new traffic.
Think of it like a coffee shop barista asking “Would you like to make that a large?” That one question adds $0.80 to every third order. Over a month, that’s thousands in extra revenue from the same number of customers.
WooCommerce has built-in upsell and cross-sell fields on product pages, but they’re basic — you manually assign related products, and they only show on the product page. No cart upsells, no checkout order bumps, no post-purchase offers. For those, you need a dedicated plugin.
35% of Amazon’s revenue comes from upselling and cross-selling (McKinsey/FunnelKit, 2025). And 72% of sellers report a 30% revenue increase after implementing upsell strategies. The math is clear: upselling existing customers is cheaper and more effective than chasing new ones.
Why Your WooCommerce Store Needs an Upsell Plugin
- It costs 5-7x more to acquire a new customer than to sell more to an existing one (Harvard Business Review). An upsell plugin lets you grow revenue from traffic you already have.
- Upsells at checkout convert at 15-20% when the product is relevant to what’s already in the cart (UpsellWP, 2026). That’s higher than most paid ad campaigns.
- Post-purchase one-click upsells convert at 10-15% because the customer has already entered their payment info — adding an item is frictionless.
- Stores using “Frequently Bought Together” bundles see AOV increases of 10-30% depending on product type and discount depth.
Real example: A FunnelKit customer reported that 30-40% of gross revenue comes from bump offers and upsells after implementing checkout upsells and post-purchase funnels (FunnelKit, 2026). For a store doing $20,000/month, that’s $6,000-$8,000 in revenue that didn’t exist before the plugin.
The smartest stores pair upsells with a customer loyalty program. The upsell gets a bigger order today. The loyalty points earned on that order give the customer a reason to come back tomorrow — without needing another discount to do it.

How I Tested These Plugins
I evaluated each upsell plugin across 6 criteria on a live WooCommerce test store (WordPress 6.7, WooCommerce 9.5, Storefront theme):
- Setup time — How long from install to first live upsell offer? I timed every plugin with a stopwatch. Anything over 15 minutes for a basic campaign is a red flag for non-technical users.
- Upsell placement coverage — Does it cover product pages, cart, checkout, AND post-purchase? Plugins that only work on one page leave money on the table at every other touchpoint.
- Free vs paid value — What can you actually do without paying? Some plugins gate essential features (like checkout bumps) behind PRO. I tested the free version first, then upgraded.
- Performance impact — I measured page load time before and after activation using GTmetrix. Any plugin adding 500ms+ is a conversion killer. Speed matters for WooCommerce checkout optimization.
- Mobile experience — Over 60% of eCommerce traffic is mobile. I tested every upsell offer on an iPhone 14 and Samsung Galaxy S23. If the popup covers the screen or buttons are untappable, it fails.
- Loyalty program compatibility — Can the plugin work alongside WPLoyalty to award points on upsold items? This matters for stores building long-term customer retention strategies.

Turn one-time upsell buyers into repeat customers with WPLoyalty.
1. UpsellWP
The best all-in-one WooCommerce upsell plugin — and the one I’d install first on any store.
I set up my first checkout order bump in 3 minutes. That’s not a marketing copy — I timed it. Install, activate, go to UpsellWP → Campaigns → Checkout Upsells, select a product, set a discount, and activate. The upsell appeared on my checkout page immediately.
UpsellWP covers every upsell touchpoint: product page (Frequently Bought Together), cart page (cross-sells), checkout (order bumps), post-purchase (one-click upsells), and thank-you page offers. Most plugins specialize in one or two of these. UpsellWP handles all of them from one dashboard.
Important detail: UpsellWP is built by Flycart — the same team behind WPLoyalty and Discount Rules for WooCommerce. This means it’s designed to work with the same ecosystem. Points earned through WPLoyalty apply to upsold items. Discounts from Discount Rules stack correctly with upsell offers. If you’re already using any Flycart product, UpsellWP slots in without conflicts.
What you get:
- Checkout order bumps — one-click add at checkout
- Frequently Bought Together — Amazon-style bundles on product pages
- Cart page cross-sells with targeted recommendations
- Post-purchase one-click upsells (PRO)
- Thank-you page offers with next-order coupons
- Added-to-cart upsell popups (PRO)
- A/B testing to compare offer variations (PRO)
- Built-in analytics tracking conversions per campaign
- WPLoyalty integration — points earned on upsold items
- 10 pre-built campaign templates
What real users say:
“It is exactly what I was looking for and at a reasonable price. They solved my problem very quickly, thank you.” — WordPress.org reviewer, 2026
“Five star support. Staff got on a call with me and helped resolve the issue. After a week of using it, I’m already seeing an increased average order value.” — WordPress.org reviewer, 2025
“Great plugin and helpful skilled devs behind it. I’m also using the Pro version of their discounts plugin, and can’t say enough good things about the Flycart team.” — WordPress.org reviewer, 2025
My honest take:
UpsellWP is my top pick for most WooCommerce stores. The free version alone covers checkout bumps and Frequently Bought Together — which are the two highest-converting upsell types. The PRO version at $75/year is the cheapest full-featured option. Skip this only if you need advanced funnel building (use FunnelKit) or you specifically want AI-powered recommendations (use WooCommerce Product Recommendations).
Pricing: Free version on WordPress.org. PRO starts at $75/year (single site). 14-day money-back guarantee.
2. FunnelKit Funnel Builder
Best for stores that want sophisticated sales funnels with A/B testing and visual workflow builders.
FunnelKit is overkill for simple upsells — and I mean that as a compliment. It’s a complete sales funnel platform that includes custom checkout pages, order bumps, post-purchase one-click upsells, downsells, and A/B split testing. Setup took me 45 minutes for a full funnel (checkout page → order bump → post-purchase upsell → downsell), but the result was more polished than anything else I tested.
The post-purchase upsell flow is where FunnelKit shines. After checkout, customers see a dedicated offer page with the product, a discount, and a one-click “Yes, add this” button. They accept without re-entering payment info. If they decline, FunnelKit can show a downsell (lower-priced alternative). This layered approach recovers revenue at every decision point.
One thing I noticed during testing: the A/B testing feature is the real differentiator. You can create two versions of the same offer page — different products, different discounts, different copy — and split traffic 50/50. After 100+ conversions, the data tells you which version wins. No other plugin on this list offers this level of testing sophistication.
The learning curve is real, though. The visual funnel builder is powerful but takes time to understand. If you want “install and go,” this isn’t it. If you want maximum AOV optimization with data-driven testing, this is the tool.
What you get:
- Visual funnel builder with drag-and-drop flow
- Custom checkout page templates (works with Elementor, Divi, Gutenberg)
- Checkout order bumps with one-click add
- Post-purchase one-click upsells and downsells
- A/B split testing on every funnel step
- Deep analytics: views, conversions, revenue per step
- Works with WooCommerce payment gateways like Stripe, PayPal
What real users say:
“30-40% of our gross revenue comes from bump offers and upsells.” — Griffin Stewart, FunnelKit customer, 2025
“The automation and funnel building features alone have paid for the subscription many times over.” — WordPress.org reviewer, 2025
My honest take:
FunnelKit is the professional’s choice. If you sell courses, high-ticket items, or digital products where a structured funnel matters, it’s the best option. But at $99.50/year and a 45-minute setup time, it’s too much for stores that just want a simple “Frequently Bought Together” section.
Pricing: Free version with limited features. Funnel Builder starts at $99.50/year (single site). 14-day money-back guarantee.

3. Merchant by aThemes
Best for stores that want upsells, trust badges, countdown timers, and 40+ conversion tools in one plugin.
Merchant isn’t a dedicated upsell plugin — it’s a conversion toolkit that happens to include strong upsell features alongside scarcity timers, free shipping bars, trust badges, and more. I liked that I didn’t need 4 separate plugins to get upsells, countdown timers, trust badges, and size charts all working.
The “Frequently Bought Together” module worked well on my test store. Setup was straightforward — 6 minutes from install to first live bundle. Select a product, assign complementary items, set a bundle discount. The offers appeared cleanly on the product page without breaking my theme layout.
What you get:
- Frequently Bought Together product bundles
- Cart upsells with complementary product suggestions
- Checkout upsells and order bumps
- Countdown timers, free shipping bars, trust badges
- Volume discounts and bulk pricing
- Size charts, sticky add-to-cart, and 35+ other modules
- Compatible with WooCommerce gamification strategies
What real users say:
“I didn’t have to install three or four separate WooCommerce plugins to get upsells, cross-sells, and cart boosts working together because everything just connected smoothly.” — WPBeginner testing review, 2026
My honest take:
If you’re installing upsell functionality for the first time AND you need trust badges, countdown timers, and other conversion tools, Merchant saves you from plugin bloat. But if you only need upsells and nothing else, UpsellWP or FunnelKit give you more depth per feature. Works well alongside WPLoyalty rewards — the trust badges and loyalty widget reinforce each other on the product page.
Pricing: Free version available. Premium starts at $79/year (single site).
4. Iconic Sales Booster
Best for clean, native-feeling upsells that don’t look like they were bolted onto your store.
Iconic Sales Booster produces the most visually polished upsell displays I tested. The “Frequently Bought Together” section, “Customers Also Bought” recommendations, and checkout order bumps all match WooCommerce’s native design language. Setup took 7 minutes — install, activate, and the first “Frequently Bought Together” section appeared on my product page with auto-generated suggestions.
One thing caught me off guard: the plugin auto-generates cross-sell suggestions based on order history, so it needs existing order data to work well. On my fresh test store with zero orders, the “Customers Also Bought” section was empty until I manually assigned products. For stores with existing sales history, this feature works automatically — which is a nice touch.
No free version, though. At $79/year, you’re paying for design quality and a focused feature set rather than a sprawling toolkit.
What you get:
- Frequently Bought Together with auto-generated suggestions
- Customers Also Bought recommendations based on order history
- Checkout order bumps with clean, minimal design
- Post-purchase upsell offers on the thank-you page
- Thank-you page product suggestions
- Customizable button text, colors, and sales messages
- Works alongside loyalty widgets without design conflicts
What real users say:
“The cross-sell and upsell features blend in perfectly with our minimal theme. Customers interact with them naturally because they don’t look like ads.” — WooCommerce Marketplace reviewer, 2025
“We switched from YITH to Iconic because the design was cleaner and the order history suggestions were more relevant.” — WooCommerce Marketplace reviewer, 2025
My honest take:
Choose Iconic if design quality matters more than price. Skip it if you need a free version to test first — UpsellWP gives you more for $0. Iconic works well alongside a loyalty levels program because its clean UI doesn’t clash with loyalty widgets.
Pricing: From $79/year (single site). 30-day money-back guarantee.

5. YITH Frequently Bought Together
Best for stores that only need product page bundles and nothing else.
YITH does one thing — Amazon-style “Frequently Bought Together” sections on product pages — and does it well. You select which products to bundle, set an optional discount, and the grouped offer appears below the product description. Customers add the entire bundle to their cart with one click.
The free version lets you display bundles but limits customization. The premium ($79.99/year) unlocks automatic product suggestions based on purchase history, layout customization, and discount options per bundle. Setup took 5 minutes.
What you get:
- Frequently Bought Together product groups on product pages
- Optional bundle discounts (percentage or fixed)
- Auto-generated product suggestions based on order history (PRO)
- Layout and positioning customization (PRO)
- Compatible with WPLoyalty points — customers earn points on bundled purchases
What real users say:
“It does this quite well by letting you show complementary products in various spots within a product page.” — Iconic WP comparison, 2026
My honest take:
YITH is solid if you ONLY want product page bundles. But at $79.99/year for that single feature, it’s hard to justify when UpsellWP includes Frequently Bought Together in its free version alongside checkout bumps, cart cross-sells, and more. Use YITH if you’re already deep in the YITH ecosystem and want consistency.
Pricing: Free version on WordPress.org. Premium at $79.99/year.
6. One Click Upsell Funnel By WpSwings
The best free option for post-purchase upsells. Period.
If you want post-purchase one-click upsells and your budget is zero, this is your plugin. It creates unlimited upsell and downsell funnels that show after checkout — customers add items without re-entering payment details. The free version includes everything: unlimited funnels, WooCommerce block checkout support, and full customization.
I was skeptical about a completely free plugin handling post-purchase funnels. But it works. I created a funnel in 8 minutes: select the trigger product, choose the upsell product, set a discount, and publish. After a test purchase, the upsell page appeared instantly with a clear “Yes, add to my order” button.
The interface is basic compared to FunnelKit. No visual funnel builder, no A/B testing, and the design options are limited. But for a free plugin doing post-purchase upsells that actually function on modern WooCommerce block checkout, it’s remarkable. The sandbox mode is useful too — you can test your entire funnel flow without affecting real customers.
What you get:
- Unlimited post-purchase upsell and downsell funnels
- One-click checkout (no payment re-entry)
- Works with WooCommerce block checkout
- Sandbox mode for testing before going live
- Compatible with WooCommerce referral programs — pair post-purchase offers with referral invitations
What real users say:
“The free version is generous. You get unlimited funnels, and the one-click checkout actually works.” — WordPress.org reviewer, 2025
My honest take:
Start here if you’re on a zero budget and want post-purchase upsells. The design limitations won’t matter if your offers are relevant. Upgrade to FunnelKit when you need A/B testing and sophisticated funnel logic. Pair with WPLoyalty’s launcher widget on the thank-you page for maximum post-purchase impact.
Pricing: Free. Premium version available for advanced features.

7. WooCommerce Product Recommendations
Best for large catalogs where manual product pairing isn’t realistic.
If you have 500+ products across dozens of categories, manually assigning “Frequently Bought Together” items for each product is impractical. WooCommerce Product Recommendations uses order history and machine learning to auto-generate suggestions — no manual setup per product. Setup took 4 minutes: install from the WooCommerce Marketplace, activate, and recommendations start appearing based on your existing order data.
The AI-generated recommendations improved as my test store accumulated more orders. Early on, suggestions were generic — recommending popular products regardless of context. After simulating 50+ orders with varied product combinations, the recommendations became genuinely relevant, surfacing items that complemented the specific product being viewed. The tradeoff: no one-click post-purchase upsells and no checkout order bumps. This plugin strictly handles product recommendation displays across your store pages.
What you get:
- AI-powered product recommendations based on order history
- Automatic “Frequently Bought Together” and “You May Also Like” sections
- Rule-based recommendations using filters and conditions
- Analytics dashboard showing recommendation performance
- No manual product pairing needed for large catalogs
What real users say:
“For a 600+ product store, manually assigning related products was impossible. This plugin handles it automatically and the suggestions get better over time.” — WooCommerce Marketplace reviewer, 2025
“The rule-based system gives you control when you need it, but the automatic mode covers 90% of use cases without touching anything.” — WooCommerce Marketplace reviewer, 2026
My honest take:
Use this for large catalogs where manual curation is impossible. Skip it for small stores (under 100 products) — you’ll get better results manually selecting upsells in UpsellWP or YITH. At $49.50/year with no checkout bumps or post-purchase funnels, it’s a supplementary tool, not a standalone upsell solution. Pair it with WPLoyalty’s purchase campaigns to award points on recommended product purchases.
Pricing: $49.50/year (WooCommerce Marketplace). No free version.

You care most about design quality → Use Iconic Sales Booster ($79/year). The most visually polished upsell displays.
You want upsells + loyalty program from the same company → Pair UpsellWP with WPLoyalty.
You want cart page optimization specifically → Use Best Upsell for WooCommerce (free). The cart builder, progress bar, and side cart drawer address cart-page drop-off better than any other plugin here.
Upsells grow today’s order — WPLoyalty brings them back tomorrow.
What Most Stores Overlook: Upselling Without Retention Is a One-Time Win
Here’s what I see repeatedly: a store installs an upsell plugin, AOV jumps 15-20%, and the owner moves on. The upsell runs on autopilot. Revenue goes up. But the customer who spent $95 instead of $60 never comes back.
Increasing retention by just 5% increases profits by 25-95% (Bain & Company/Harvard Business Review). And repeat customers spend 67% more than new ones (BIA/Kelsey, via WPLoyalty). An upsell without a retention strategy captures the high-value order once. An upsell paired with a loyalty program captures it repeatedly.
Consider this scenario: a customer buys a $60 phone case and your checkout bump adds a $15 screen protector. That’s a $75 order — great. But without follow-up, that customer has no reason to return. Now imagine they earned 75 loyalty points on that order. Those 75 points are worth $7.50 toward their next purchase. They get an email: “You have $7.50 in rewards waiting.” That email has a 40%+ open rate and brings them back to spend $60+ again — at full price.
Alt text: Infographic showing $60 order add-on 75 reward points repeat purchase via email
With WPLoyalty, every upsold item earns points. The customer who added a $30 accessory to their $60 electronics order earned 90 points — that’s $9 toward their next purchase. One upsell turned a single transaction into an ongoing relationship.
This is the connection every competitor article misses. They tell you HOW to upsell. They don’t tell you how to keep the customer you just upsold to. That’s where WPLoyalty’s points system,point expiry for urgency, and birthday rewards for personal touch all compound.
🔷 Install WPLoyalty free and start awarding loyalty points on every purchase — including upsold items. Setup takes under 10 minutes. Then pair it with UpsellWP for a system that increases order value AND customer lifetime value.

Frequently Asked Questions
UpsellWP for checkout bumps, Frequently Bought Together, and cart cross-sells — all free. One Click Upsell Funnel for free post-purchase upsells specifically. Both work on WooCommerce 8.0+ and don’t require any premium upgrade for basic functionality.
Depends on the plugin. I tested all 8 with GTmetrix. UpsellWP and Iconic added under 100ms. FunnelKit added 200-300ms on funnel pages (acceptable). One plugin I initially tested (not included here) added 800ms+ — I removed it immediately. Speed matters for conversions, so test load times after installing any plugin. See our guide on speeding up WooCommerce.
Yes, but don’t install two plugins that target the same placement. For example: UpsellWP for checkout bumps + One Click Upsell Funnel for post-purchase offers works fine. Two plugins both showing checkout bumps will conflict. Think complementary, not overlapping.
UpsellWP — built by the same company (Flycart). Points earned through WPLoyalty apply to upsold items automatically. The Discount Rule Integration add-on lets you offer tier-specific upsell pricing for Gold/Platinum loyalty members.
Data varies. UpsellWP reports 30-50% AOV increases for active users. FunnelKit customer Griffin Stewart attributes 30-40% of gross revenue to bump offers and upsells. Conservative expectation: 10-20% AOV increase with well-targeted offers on checkout and product pages.
Yes. With WPLoyalty, all purchased items (including items added via upsell offers) earn points. You can even award bonus points on upsold items to encourage customers to accept upsell offers — “Add this accessory and earn double points.”
