Checkout Wiz (Wiz: Checkout Upsell & Rules), by Skai Lama, is a Built for Shopify app that turns the checkout and post-purchase flow into a revenue driver. It combines AOV boosters, checkout customization, and A/B testing to grow sales without disrupting the customer experience.
Key features
- AOV boosters: checkout upsells, volume discounts, subscription upgrades, and free gifts with purchase.
- Built-in A/B testing: test every block to see what actually converts.
- Post-purchase flows: 1-click post-purchase upsells, thank-you-page offers, and order summaries.
- Checkout customization: trust badges, reviews, shipping info, free-shipping bar, and available discounts.
- Insights: post-purchase surveys and real-time performance tracking.
Pricing and rating
Checkout Wiz starts at $49/month (Essential: post-purchase upsell funnels, thank-you and order-status customizations, shipping and payment rules), with a 14-day free trial. The $99/month Plus Growth plan adds checkout upsells, subscription upgrades, trust badges, input fields, and free gifts, and the $199/month Checkout Concierge plan adds A/B testing, custom onboarding, and monthly review calls.
It holds a 4.9 rating from 53 reviews, with 94% at five stars. Merchants highlight easy setup, steady improvements, AOV gains, and a quick, responsive support team.
Pitfalls
Checkout-page upsells and customizations sit on the $99 Plus Growth plan, and A/B testing requires the $199 Concierge plan, so the headline features are not on the entry tier. The review base is still modest, and support is offered in English.
Conclusion
Checkout Wiz is a capable all-in-one checkout and post-purchase upsell tool, and its built-in A/B testing is a real differentiator for stores serious about optimization. For brands ready to invest beyond the entry plan, it offers a strong, well-supported path to a higher-converting checkout.
