Choosing an upsell app isn't just about features - pricing can make or break the ROI. Some apps charge $15/month for basic features and $100+/month for advanced ones. Others charge based on your order volume regardless of upsell performance.
This guide breaks down how each major app charges you, so you can see the real cost - not just the advertised price.
The Two Pricing Models
Before diving into individual apps, understand the two fundamentally different approaches:
Order-based pricing (AfterSell, Candy Rack, and ReConvert, which bills on orders or upsell revenue, whichever is higher): Your monthly fee is determined by how many orders your store processes. 500 orders/month? AfterSell charges $34.99/mo. Candy Rack charges $59.99/mo. The problem: this penalizes store growth. A store doing 1,000 orders/month pays the same whether upsells generate $100 or $10,000.
Revenue-based pricing (Kairo, Zipify OCU): Your fee is based on how much upsell revenue you actually generate. This aligns the app's pricing with your success - you pay more only when you earn more. Note: CartHook uses a hybrid approach (fixed fee + 1% revenue fee on all plans).
App-by-App Pricing Breakdown
Kairo - $8/month base, usage-based tiers
Starts at $8/month. Pricing scales with upsell revenue through 12 tiers. All features included at every level - no feature gating. 14-day free trial. Development stores free. Kairo's AI builder also generates complete offers from your catalog in 3 minutes, so you start earning faster.
AfterSell - Order-based, from $34.99/month
Since September 2026, new stores pay $34.99/mo for the first 500 orders, then $0.05 per order, capped at $999.99/mo. Stores already on AfterSell keep their older tiers ($54.99/mo at 1,000 orders, $99.99/mo at 2,000). No revenue fee. 30-day free trial. Checkout upsells (Shopify Plus) are included. The cost grows with your order volume, not your upsell success. See the full AfterSell pricing breakdown.
ReConvert (now Upsell.com) - Orders or upsell revenue, free-$499+/month
Bills every 30 days on your store's total orders or the upsell revenue it generates, whichever is higher.

The revenue that sets the tier includes tax on upsell items. Stores installed before then keep their older plan. 30-day free trial. The cost is higher than Kairo at most revenue levels.

Hidden Costs to Watch For
- Feature gating: Some apps advertise a low starting price but lock A/B testing, advanced analytics, or more offer templates behind higher tiers. Make sure the features you need are included in the plan you're comparing.
- View/impression caps: Some apps limit how many times your offers can be shown per month. If you exceed the cap, you're forced to upgrade.
- Overage charges: Going above your order or revenue tier mid-month can trigger automatic upgrades or overage fees.
- Template costs: A few apps charge extra for premium templates or advanced editor features.
