Checkout Plus, by Plus Apps, is a Built for Shopify app for customizing the checkout, thank-you, and order-status pages. It helps stores raise AOV and build trust with upsells, social proof, and information capture, plus rule-based control over payment and shipping methods.
Key features
- Upsells: checkout and post-purchase upsells to increase average order value.
- Social proof: reviews, UGC, and trust badges at checkout.
- Information capture: gift messages, delivery instructions, surveys, and forms.
- Post-purchase pages: thank-you, order-status, and customer-account customizations.
- Rules: payment, shipping, and order-limit customizations based on conditions.
Pricing and rating
Checkout Plus offers a free plan for development and staging stores and a 7-day free trial. Paid plans start at $29/month (Basic: thank-you and order-status customizations, payment and shipping rules, order limits, post-purchase upsells), with $49/month (Plus) and $89/month (Advanced) adding full checkout customization, checkout upsells, branding, and surveys for Shopify Plus stores.
It holds a 5.0 rating from nearly 100 reviews, with 98% at five stars. Merchants highlight the depth of features, fair flat pricing, and prompt, hands-on support from the founder.
Pitfalls
Checkout-page customizations and checkout upsells require Shopify Plus (the $49 and $89 tiers), so non-Plus stores rely on thank-you, order-status, and post-purchase features. The free plan is limited to development and staging stores, and support is offered in English.
Conclusion
Checkout Plus is a feature-rich, well-supported checkout-customization app with refreshingly flat pricing that starts at $29/month. It is an excellent fit for stores that want upsells, trust building, and post-purchase customization — and especially strong for Shopify Plus brands that can unlock full checkout editing.
