The Best Shopify Checkout Apps for Plus Merchants (2026)

The Best Shopify Checkout Apps That Actually Move Revenue

Your checkout is the last 60 seconds of every customer interaction. On standard Shopify, you can't touch it. On Shopify Plus, you can install checkout apps that change what happens in those 60 seconds, and the revenue difference compounds fast.

A 0.5% checkout conversion improvement at $10M annual revenue is $50,000. At $30M, it's $150,000. That's why Shopify checkout apps matter, and why this guide focuses on the ones that produce measurable results for beauty, skincare, wellness, and supplement brands on Shopify Plus.

This isn't a list of 30 apps. It's the Shopify checkout apps that Plus merchants actually install, actually keep, and can actually point to revenue impact.

Why Shopify Plus Checkout Is Different

Standard Shopify checkout is locked. You get a logo, brand colors, and that's it. No custom elements. No post-purchase offers. No trust signals next to the payment button. No trial programs.

Shopify Plus uses checkout extensibility through Checkout UI Extensions and the Checkout Editor. These are API-based tools that let apps add custom elements to every step of checkout without breaking the underlying infrastructure. Your checkout stays stable and trusted. But now apps can build on top of it.

Every app in this guide requires Shopify Plus or performs significantly better with Plus-level checkout access. If you're on a standard plan, here's how to know when it's time to upgrade.

Checkout App Categories That Matter

The Shopify checkout apps worth installing fall into five categories. Not every store needs all five. But understanding what each category does helps you prioritize based on your biggest conversion bottleneck.

1. Try-Before-You-Buy: TryNow

This is not a checkout widget. It's a fundamentally different checkout experience that turns your store into a customer acquisition channel.

TryNow integrates directly into Shopify Plus checkout so that eligible products show a $0 authorization instead of a charge. The customer sees "Due Today: $0.00" right where she'd normally see her total. Her card is authorized but not charged. She receives products, tries them for 7-21 days, and only pays for what she keeps.

TryNow is Shopify's design and launch partner for try-before-you-buy APIs. It's the only TBYB solution built natively on Shopify Plus checkout extensibility.
