What Is the Best Shopify Upsell App? How to Choose
Short answer
The best Shopify upsell app depends on where you want offers to appear. Post-purchase one-click upsell apps are low-risk and often the best starting point; cart and product page apps suit bundles and add-ons; checkout upsells require checkout extensions. Choose an app with relevant targeting, good speed, clear analytics and pricing that fits your volume.
Upsell apps promise higher average order value with little effort. Many deliver; some clutter your store and slow it down. Rather than crowning one winner, here is how to pick the right type and app for your store.
Types of upsell apps
Product page upsells and bundles
Show upgrades, bundles or "frequently bought together" offers on product pages.
Good for: stores with complementary products and clear bundle opportunities.
Cart upsells
Suggest add-ons in the cart or cart drawer, often combined with free shipping progress bars.
Good for: low-cost add-ons and threshold-based offers.
Checkout upsells
Offers inside the checkout itself, built with Shopify checkout extensions. Availability and capabilities depend on your plan.
Good for: last-minute add-ons like protection plans, gifts or small accessories.
Post-purchase upsells
One-click offers shown after payment, before the thank-you page. Customers can accept without re-entering payment details.
Good for: almost any store. Because the main purchase is complete, these offers do not risk the original sale, which makes them a common starting point.
Email upsells
Recommendations in post-purchase and replenishment emails through your email platform.
Well-known apps
Shopify's App Store has many upsell apps. Popular names over recent years include ReConvert (post-purchase and thank-you page), AfterSell (post-purchase and checkout), Zipify OneClickUpsell, Frequently Bought Together by Code Black Belt, and various cart drawer apps with upsell features. Features, pricing and quality change frequently, so treat any list as a starting point and compare current reviews.
Features to compare
| Feature | Why it matters |
|---|---|
| Targeting rules | Show relevant offers based on cart contents, customer or value |
| AI or automatic recommendations | Saves setup time, but check relevance |
| A/B testing | Compare offers and placements |
| Analytics | See take rate and revenue added |
| Design control | Match your brand |
| Speed impact | Avoid slowing pages |
| Built for Shopify status | Signal of quality and integration |
| Pricing model | Flat, tiered or revenue share |
Watch out for pricing based on a percentage of upsell revenue; it can get expensive at scale.
How to choose
- Pick one placement to start. Post-purchase is low-risk.
- Shortlist two or three apps for that placement.
- Check reviews sorted by most recent.
- Install on a duplicate theme and test speed.
- Run a test order to experience the flow.
- Launch with a few well-chosen offers, not dozens.

What makes a good upsell offer
- Relevant to the product purchased
- Lower priced than the main item, often well below it
- Clear value, like a discount or bundle saving
- Simple to accept or decline
- Honest, with no fake timers
Measuring results
Track:
- Average order value
- Upsell take rate
- Revenue added per order
- Overall conversion rate (make sure it does not drop)
- Refunds on upsold items
If take rate is low, try different products or a better incentive. If conversion falls after adding product page or cart upsells, they may be distracting.
Example upsell offers that tend to work
- A refill or second unit at a small discount after buying a consumable
- A matching accessory after buying apparel
- A protective case or care kit after buying a device or leather goods
- Gift wrap after buying an item marked as a gift
- Faster shipping close to holidays
Start with the most natural pairing for your bestseller and expand from there.
Free alternatives first
Before paying, try:
- Theme product recommendations
- Shopify's Bundles app
- Automatic discounts like "buy 2, get 10% off"
- Free shipping thresholds

Frequently asked questions
Do upsell apps slow down Shopify stores?
Some do, especially those loading scripts on every page. Test page speed before and after installing, and prefer apps using theme app extensions.
Can I upsell at Shopify checkout?
Checkout upsells are possible through checkout extensions and apps, with availability depending on your Shopify plan. Post-purchase pages are available more broadly.
Are free upsell options available in Shopify?
Shopify's product recommendations in themes, its Bundles app and native discounts can cover basic cross-sells and bundles without a paid upsell app.
