7 Best WooCommerce Upsell & Cross-Sell Plugins to Boost Revenue

Tested, compared, and ranked honestly. From lightweight checkout tools to full funnel builders — find the right plugin for your store’s size, budget, and goals.

Smart Funnel takes a focused, checkout-first approach. Rather than trying to replace your entire WooCommerce store flow or build you a landing page system, it solves three specific problems well: adding order bumps at checkout, showing a related products grid during checkout, and presenting a post-purchase upsell modal after the order is confirmed.

What makes it stand out is the admin experience. Offers are managed from a single, clean panel where bumps, upsells, and related products each live in their own tab. Creating a new bump takes under five minutes: pick the product, set the discount, define the targeting condition, done. No page builder. No code. No settings buried four menus deep.

The targeting conditions let you show different offers based on what is in the cart — which is the single most important factor for bump acceptance rates. Smart mode for related products learns from purchase history over time, so the grid improves as your store generates data. The dashboard tracks views, acceptances, and revenue per offer, giving you the data to iterate without guessing.

FunnelKit is the most comprehensive sales funnel builder available for WooCommerce. It goes significantly beyond upsells and cross-sells: you can redesign the checkout page entirely, add order bumps, create one-click post-purchase upsells, build opt-in and thank-you pages, run A/B tests on every step, and connect it all to email automation sequences. Trusted by over 30,000 stores, it is the most-installed dedicated funnel tool for WooCommerce.

The trade-off is complexity and price. The free version covers basic funnel structure but locks out order bumps, analytics, and upsells — you need the paid tier for anything meaningful. The starting Pro plan at $99.50/yr is reasonable, but upsells and A/B testing require higher tiers. For stores that want a visual, page-builder-driven checkout experience with comprehensive analytics, FunnelKit is the strongest choice. For stores that just want clean checkout bumps without rebuilding their purchase flow, it is more than they need.

CartFlows built its reputation on one core idea: the default WooCommerce checkout page is not optimised for conversion, and the right tool should replace it entirely with a cleaner, faster, distraction-free checkout flow. With over 4 million active installs (including the free version), it is one of the most widely used funnel plugins in the WordPress ecosystem.

The paid Plus plan at $189/yr includes order bumps, one-click upsells, A/B testing, and funnel analytics. The checkout replacement approach works well for stores running paid ad campaigns where landing page quality matters. For stores that want to add upsells without disrupting an existing, well-performing checkout, the full replacement model can introduce unnecessary risk.

UpsellWP is built around the idea that upsell opportunities should exist at every point of the customer journey — not just at checkout. It covers product pages, cart pages, checkout, post-purchase, and thank-you pages with a range of campaign types including order bumps, popups, inline cross-sells, and next-order coupons. Ten pre-built campaign templates help beginners get started without configuring everything from scratch.

The smart recommendation engine — which generates suggestions based on cart contents, purchase history, and customer behaviour — is UpsellWP’s most distinctive feature. At $55/yr for Pro, it represents solid value for stores that want coverage across the entire storefront rather than just the checkout page. The free version is functional but limited; the meaningful campaigns require the Pro plan.

YITH’s Frequently Bought Together plugin does one thing: it adds an Amazon-style “frequently bought together” section to your product pages, where customers can add a curated bundle of complementary items in a single click. It is one of the most recognisable patterns in e-commerce, and YITH implements it cleanly.

The important caveat is that this plugin works on product pages only — there is no checkout bump, no post-purchase upsell, and no cross-sell at cart or payment stages. If your AOV strategy only needs the product page bundle pattern and nothing else, YITH is a reasonable choice. For most stores, though, combining it with a checkout-focused tool is necessary to cover the full funnel. It is also worth noting that the free version on WordPress.org has notably poor reviews (3.1/5) due to key features being locked behind the paid tier.

Iconic Sales Booster covers upselling and cross-selling at multiple stages — product page, cart, checkout (order bumps), and post-purchase — without replacing the default WooCommerce checkout. Unlike FunnelKit and CartFlows, it works within your existing store structure rather than replacing it. The result is a plugin that feels more native to WooCommerce, with less setup complexity.

The “Frequently Bought Together” feature and order bump functionality are both clean and well-designed. At $79/yr it is priced above Smart Funnel but significantly below CartFlows, which makes it a reasonable middle-ground option for stores that want multi-page coverage without the overhead of a full funnel builder. The 30-day money-back guarantee is also a genuine plus for first-time buyers.

This is the official product recommendations extension built and maintained by the WooCommerce / Automattic team. It uses machine learning and order history to automatically generate relevant product suggestions across your store — on product pages, in the cart, and at checkout — without manual configuration of individual product pairings.

The main selling point is automation: the system learns from real purchase patterns and adapts over time, which is valuable for stores with large catalogues where manually managing pairings is impractical. The trade-off is that it focuses on recommendation display rather than conversion optimisation — there are no order bump mechanics, no post-purchase modals, and no discount triggers. For stores that want an intelligent recommendation layer alongside a dedicated checkout tool, it works well as a complement. As a standalone AOV driver, it is limited.
