What is the best Selleasy alternative for Shopify?

Essential Upsell & Cross Sell is a strong Selleasy alternative on Shopify if you sell in several languages, want a Built for Shopify app, or want free companion apps for checkout, cart drawer and page tests. Selleasy is the better pick for the biggest free plan and built-in thank-you page offers.

How do the plans and prices compare?

On Shopify, Selleasy and Essential Upsell & Cross Sell both start free and both have a first paid plan near $10. Selleasy's free plan is bigger, with unlimited orders and 5 campaigns. Our free plan covers up to $100 of added monthly revenue, and our paid tiers scale with that added revenue.

The limits are different kinds, so you can't convert one into the other. Selleasy caps campaigns and AI recommendations. We cap added revenue, counted when an order is completed (the trigger product in a frequently bought together offer isn't counted). Outgrow a plan and you move up automatically. Ours has a 30-day money-back guarantee. All eight tiers are on our pricing page.

Which app has better offers and placements?

Both apps cover product page, cart and post-purchase offers on Shopify. Selleasy adds thank-you and order status page offers and, on its Pro plan, Shopify Plus checkout upsells. Essential Upsell & Cross Sell adds thank-you page offers through the free Essential Checkout app, a separate install.

Essential Upsell & Cross Sell has product page, cart page, post-purchase and pop-up offers. Product and cart offers come as cross-sell, add-on or frequently bought together, triggered by product, collection or cart value, with exclusions. See our guide to adding frequently bought together on Shopify.

Our post-purchase upsell shows after payment and before the thank-you page. Accepted items are added to the original order and charged automatically. You can add a second offer and a downsell, with a percentage or fixed discount. Cart offers are covered on the cart upsell page; to show them inside a cart drawer you also need Essential Cart Drawer.

One honest limit: Shopify, not the app, decides when the post-purchase page shows. It's skipped for some payment methods (Klarna, Affirm, Afterpay, Sezzle, Apple Pay, Google Pay, Shop Pay express, cash on delivery, bank transfers), orders under $0.50 and orders not in the store's default currency. Our help docs say this affects all post-purchase upsell apps. Neither listing shows offer-level A/B testing.

What does the Essential app suite add?

Essential Upsell & Cross Sell is one of 14 Essential apps for Shopify, and our homepage says every app has a free plan. Three companions fill gaps in the Upsell app: Essential Checkout for thank-you page offers, Essential Cart Drawer for cart offers and free gifts, and Essential CRO Split AB Testing for page templates. They're separate apps.

• Essential Checkout is free and Built for Shopify (5.0, 14 reviews). It adds thank-you page offers and banners for chosen orders, a free shipping bar upsell inside checkout, payment and shipping method rules, validation and checkout discounts. 7 languages. Essential Checkout's listing doesn't state a Shopify Plus requirement; check Shopify's rules for your plan.

• Essential Cart Drawer is Built for Shopify (5.0, 1,207 reviews). It adds cart upsells, spend tiers with free shipping and free gifts, a progress bar and custom HTML and CSS. The free plan covers 30 orders a month; paid plans start at $8.99.

• Essential CRO Split AB Testing is free and Built for Shopify (5.0, 28 reviews). It split-tests page templates and themes with no page flicker. It does not test individual upsell offers, and it's English only.

The trade-off is more than one install. Selleasy's listing shows no companion apps, so what it offers sits inside one app.

How does support compare?

Both apps publish comparable support for Shopify merchants. Selleasy lists chat, email and Zoom support on its free plan, a free setup call on Starter and priority support on Max. Essential Upsell & Cross Sell's site says "Real humans, 24/7", and our homepage says the team usually replies in under 10 minutes. Those are published claims, so test either before you commit.

How do offers look, and which languages are supported?

Essential Upsell & Cross Sell installs as a theme app embed with no code and supports 20 languages on Shopify, against 7 for Selleasy. Our post-purchase offer inherits your checkout styling, and cart and pop-up offers have adjustable text, layout and colors. Selleasy lists custom CSS, and advanced customizations on its Max plan.

Our 20 languages are English, French, German, Italian, Spanish, Portuguese (Brazil), Portuguese (Portugal), Japanese, Czech, Danish, Finnish, Korean, Norwegian (Bokmål), Polish, Swedish, Thai, Turkish, Chinese (Simplified), Chinese (Traditional) and Dutch. Selleasy lists English, German, French, Spanish, Dutch, Portuguese (Brazil) and Chinese simplified. We also carry the Built for Shopify badge, Shopify's own bar for performance, design and integration. Selleasy's listing doesn't show it, which isn't proof of anything on its own. Shopify limits button customization on the post-purchase page for every app.

Where is Selleasy stronger?

Selleasy is stronger on the free plan, built-in thank-you and order status page offers, Shopify Plus checkout upsells, trial length and review count. It has been on Shopify since 2021 and has 2,782 reviews at 4.9 stars. For a small store, it's the stronger free start.

• No order limit on the free plan, with 18 strategies and 5 campaigns.

• Thank-you and order status page offers inside the app.

• A Plus checkout upsell on the $29 Pro plan.

• A 30-day trial against our 14 days, and a free setup call on Starter.

• More reviews (2,782 against 2,486) and a longer track record.

Which app is better for different use cases?

How do you switch from Selleasy to Essential Upsell & Cross Sell?

Rebuild your best offers in Essential Upsell & Cross Sell, because offers don't carry over between apps. Both apps can run side by side on Shopify while you test, as long as they don't share a placement.

1. List your active Selleasy campaigns and keep the ones that convert.

2. Install Essential Upsell & Cross Sell and rebuild those offers for the product page, cart and post-purchase page.

3. Preview them on a test product.

4. Under Settings > Checkout, choose Essential Upsell as the post-purchase app. Only one post-purchase app can be active.

5. Turn off the matching Selleasy campaigns, then uninstall it.

Two apps on one placement means two competing offers, which is one more than you want. Paid plans have a 14-day free trial and a 30-day money-back guarantee.
