5 Best One-Click Checkout Shopify Apps to Simplify Your Store’s Checkout

Checkout is the last thing standing between a shopper and a sale, and every extra second or click can cost you revenue.

If you’re running a growing Shopify store, you’ve probably felt the pain: abandoned carts, endless forms, and mobile drop-offs that hurt more than they should.

There’s a faster way to get your customers from cart to ‘thank you.’ And it starts with simplifying your checkout.

Why Fast, Easy Checkout Matters for Every Shopify Store

Slow checkout means lost sales. It’s that simple.

Today’s shoppers expect speed, ease, and zero frustration, especially when buying on mobile. If your checkout process is clunky or slow, you’re giving them a reason to leave. In fact, studies show that nearly 70% of online shopping carts are abandoned, and one of the biggest reasons is a complicated or time-consuming checkout.

That’s where one-click checkout Shopify apps come in.

One-click checkout allows customers to skip the form-filling and go straight to purchase with their saved information, no extra steps, no hesitation. In 2025, this isn’t just a nice-to-have. It’s a must for brands that want to stay competitive.

For scaling merchants, this shift isn’t just about convenience; it’s about unlocking more revenue. A frictionless checkout experience can mean higher conversions, faster repeat purchases, and a major lift in customer satisfaction.

Throughout this guide, we’ll explore how Shopify checkout apps are making it easier than ever to reduce drop-offs, speed up sales, and optimize every step of the buying journey. If you’re looking for Shopify apps to increase sales, checkout is the first place to start.

What Is One-Click Checkout and How It Works in Shopify

So, what is one-click checkout exactly?

It’s a way to let your customers complete their purchase instantly, without entering their shipping details, payment info, or clicking through multiple steps. Also known as 1-click checkout or instant checkout, it removes the friction that causes buyers to hesitate or drop off.

In the Shopify ecosystem, this often takes the form of Shopify Express Checkout options like Shop Pay, Apple Pay, and Google Pay. These methods securely store customer details and offer a fast lane at checkout, especially useful for mobile shoppers in a hurry.

That’s a lot of steps.

With instant checkout Shopify tools, repeat customers can skip most (or all) of that. They can literally buy in seconds, sometimes without ever leaving the product page.

If you’re curious, Shopify outlines its full checkout process, but the key takeaway is simple: the fewer clicks, the more sales. Especially for repeat buyers, one-click checkout builds momentum and trust, turning browsers into loyal customers.

How One-Click Checkout Helps You Sell More and Keep Customers Happy

The path to higher conversions often comes down to one thing: speed. With Shopify one-click checkout, you’re giving your customers what they want most: a fast, hassle-free way to complete their purchase.

Checkout is where trust is either won or lost. A long, slow process creates doubt. But a fast checkout Shopify experience builds confidence. It tells your customers: “You’re in good hands, we respect your time.”

User experience matters even more on mobile. Most shoppers now browse and buy from their phones, where typing is harder and attention spans are shorter. A seamless checkout experience eliminates unnecessary steps, taps, and load times, helping buyers convert in seconds instead of minutes.

Here’s why it matters: the average conversion rate for a Shopify store is just 1.4%. Stores in the top 10%? They see rates above 4.7%. That’s not luck, it’s often the result of removing friction from key points like checkout.

By making buying easier, faster, and more intuitive, one-click checkout doesn’t just lift your sales; it leaves customers with a better experience. And in ecommerce, a smooth experience is what brings people back.

Choosing the Right Checkout App: What to Look for Before You Install

Not all checkout solutions are created equal. If you’re searching for the best checkout apps for Shopify, it’s important to know what actually drives results and what just adds noise.

Always test your checkout speed with tools like Google PageSpeed or Shopify’s built-in analytics. Even a one-second delay can impact sales.

With so many Shopify checkout apps on the market, it can be tough to know which ones are actually worth your time and which ones will truly help you convert more customers.

You don’t need dozens of tools. You just need one that does the job right: speed, simplicity, and trust at checkout.

Whether you’re looking to reduce abandoned carts, speed up mobile purchases, or create a seamless buying journey from product page to post-purchase, these tools stand out for all the right reasons.

Let’s dive in.

Shop Pay

Shop Pay is Shopify’s native accelerated checkout and one of the most powerful tools available for stores looking to increase speed and conversion without added complexity. It securely stores your customers’ shipping and payment info, allowing them to complete purchases with a single tap across your store, social channels, and even the Shop app.

Trusted by over 150 million global shoppers, Shopify one-click checkout with Shop Pay isn’t just fast, it’s proven to convert. In fact, stores using Shop Pay see at least 10% higher conversion rates compared to other accelerated checkouts. And its built-in order tracking creates a smooth, branded post-purchase experience that keeps customers coming back.

Kwik COD & Checkout

Kwik COD & Checkout is a smart Shopify checkout app built to solve one of the most overlooked challenges in ecommerce: cash-on-delivery (COD) risks and returns. Designed for stores where COD is common, this tool streamlines the checkout process, reduces RTO (Return to Origin), and encourages prepaid orders, all while delivering a faster, more controlled buying experience.

It supports a customizable, frictionless checkout flow with features like smart login, pre-filled addresses, and dynamic discounts for prepaid payments. By verifying buying intent using OTP, CAPTCHA, and risk profiling, it prevents fraudulent or non-serious COD orders, protecting your margins while increasing conversions.

Instant Checkout – Buy Button

Instant Checkout – Buy Button is a lightweight Shopify app designed to speed up purchases by skipping the cart page entirely. It adds an animated “Buy Now” button to your product, collection, and even homepage listings, guiding shoppers straight to checkout with one click.

This app is all about reducing steps and increasing focus. Especially on mobile, fewer taps mean fewer drop-offs. By streamlining the path to purchase, Instant Checkout helps you deliver a fast checkout Shopify experience that converts better and keeps shoppers engaged. You can fully customize the button’s look and placement to match your store’s brand and style.

PF: Buy Now Skip Cart Checkout

PF: Buy Now Skip Cart Checkout is a conversion-focused Shopify app that removes friction from the buying journey by letting you skip the cart page entirely. Instead of sending customers to a traditional cart, PF routes them directly to checkout, reducing drop-offs and encouraging faster purchases.

What sets PF apart is its extra layer of control. You can hide cart elements, remove Buy Now or Add to Cart buttons for specific products, and even disable Express Checkout methods like PayPal, Shop Pay, or Apple Pay when needed. This makes it a great option for merchants running flash sales or promotions where speed and simplicity are everything.

EZ – Quick Buy & Quick View

EZ – Quick Buy & Quick View helps you speed up the shopping journey by placing a Quick Buy button directly on your homepage, collection pages, and product lists. Instead of making customers click through to a product page, this app gives them the power to buy on the spot, either by adding to cart or jumping straight to checkout.

Perfect for mobile users and impulse buyers, the bold Buy Now button draws attention and minimizes the number of steps to purchase. It’s an easy way to reduce abandoned carts and improve your store’s conversion rate by delivering a faster, more focused checkout experience.
