Shopify checkout customization is the fastest way to unlock hidden revenue in your store, yet 90% of brands ignore it.
Fine-tuning your checkout process by just 2% can earn you THOUSANDS in revenue. And yet, almost all Shopify stores utilize checkout in its default, uncustomized form, leaving HUGE OPPORTUNITIES FOR GROWTH UNTOUCHED. In a world where e-commerce is hyper-competitive, CHECKOUT IS YOUR MOST IMPORTANT CONVERSION TOOL. Want to give yourself a leg-up versus your competition, grow your revenue, and create loyal, long-lasting customers? Let’s talk about how checkout customization can give you that, starting today.
Shopify is a powerful force in e-commerce, accounting for just over 10% of e-commerce sales worldwide. But a lot of customers are leaving these stores without completing their purchases, and no one knows about it! 69% of all shopping carts are abandoned, and most of the time it is because the checkout process is not as smooth as it can be (Barilliance). Shopify has done a great job at making the checkout process as simple as can be; unfortunately, that has meant that stores have to forego making meaningful connections and sales. There’s a major lack of personalization.
In the world of e-commerce, the only way to go is to personalize 100% of the experience. 10-15% greater revenue, and 10-15% more loyal customers to your business. The checkout escape is the only experience that your company will have to go through before customers make payments. If yourCustomers only go through that experience once, sales are going to be very few.
Branded checkout pages build trust, increase confidence, and reduce abandonment by frictionless checkout. A Baymarch Institute confirmed optimized checkout pages lead to a 10-15% increase in conversion.
Post-Purchase checkout pages are often ignored but are a lifetime customer opportunity. Custom integration of upsell, upside, thank-you, referral, or survey to pp checkout can increase customer loyalty and increase repeat business.
Something as simple as a logo and a brand color on a checkout and post-purchase screen makes a thoughtful brand reinforcement at strategic moments. A consistent experience gives a brand a unique identity and offering, which sets customer expectations.
The customization of checkout pages allows A/B testing in personalized adapted checkout pages. Continuous testing with different layouts, copy, or various elements in different orders enhances conversion at optimized checkout pages.
Note: Customizing the native Shopify checkout adjustments vary with your plan. With Shopify Plus there is full control with checkout.liquid, whereas the standard plans have limitations. Most SMBs use 3rd party apps like Twinr for the drag-and-drop functionality, and are agnostic.
Only Twinr provides the opportunity to customize checkout and thank-you pages due to their no-code drag-and-drop design.

Example 3: OrganicSkin

The last interaction with your customers can yield the greatest impact. According to Shopify, it is 5-25 times cheaper to keep an existing customers than to gain a new one. This makes personalized checkout and post-purchase strategies important for generating trust and customer loyalty, which ultimately leads to an increase revenue.
Additionally, a McKinsey study found that customizing each step of the customer journey leads to a 10-15% increase in revenue . Checkout and post-purchase pages can be one of the easiest and highest revenue generating pages of the customer journey.
The Shopify default checkout system does not focus on the three key areas for maximizing revenue building loyalty and differentiating your brand. Most merchants overlook this critical moment in their customer journey. Customized checkout and post-purchase pages offer merchants the opportunity to unlock rapid and, in many cases, exponential growth. Whether it’s A/B testing, social proof, or personalized offers, merchants need a solution that is simple, fast, and scalable.
