Your checkout page is where browsers become buyers. It's the most critical page on your entire store—and on most platforms, it's the one you're least allowed to touch. CartOS believes that's backwards. That's why our Checkout Page Customizer gives every merchant full control over their checkout experience, regardless of subscription level.
The $2,500/Month Checkout Tax
On Shopify, if you want to customize your checkout beyond basic logo and color changes, you need Shopify Plus. That's a minimum of $2,500 per month, $30,000 per year, just for the privilege of optimizing your most important page.
For growing brands, this creates an impossible choice: accept a generic checkout that looks like every other store, or pay enterprise prices before you've reached enterprise scale. Many merchants are forced to watch their conversion rates suffer, knowing exactly what changes would help but being locked out of making them.
CartOS takes a different approach. We believe checkout customization is a fundamental feature, not a premium upsell. Every CartOS merchant, from day one, on every plan has access to our full Checkout Page Customizer.
What You Can Customize
The CartOS Checkout Page Customizer gives you granular control over every aspect of your checkout experience.
Layout and Structure
Choose between single-page and multi-step checkout flows. Rearrange sections to match your customers' expectations. Hide fields you don't need, or add custom fields for gift messages, delivery instructions, or purchase order numbers. Control the visual hierarchy to guide customers smoothly through the process.
Branding and Design
Your checkout should feel like a seamless extension of your store, not a jarring transition to a generic payment form. Customize colors, typography, spacing, and borders. Add your logo, adjust button styles, and ensure every pixel reflects your brand identity.
Trust Elements
Add trust badges, security indicators, and guarantee messaging exactly where they'll have the most impact. Display accepted payment methods, money-back guarantees, or shipping promises. Position social proof and testimonials to reassure customers at the moment of purchase.
Upsells and Cross-sells
The checkout page is prime real estate for increasing average order value. Add one-click upsells, order bumps, and product recommendations without cobbling together third-party apps. Configure which products to suggest based on cart contents, customer history, or your own rules.
Custom Content Blocks
Insert banners, messages, countdown timers, or promotional content anywhere in your checkout flow. Announce free shipping thresholds, highlight limited-time offers, or display estimated delivery dates. Update content instantly without touching code.
A/B Test Everything
Customization is powerful, but optimization requires testing. The Checkout Page Customizer integrates directly with CartOS's Split Bolt, letting you A/B test any element of your checkout.
Test single-page versus multi-step flows. Compare different upsell placements. Try various trust badge configurations. Measure the revenue impact of every change with statistical significance, then roll out winners automatically.
On platforms that restrict checkout access, you're flying blind. On CartOS, you have the data to make informed decisions about your most important page.
Mobile-First Checkout
With over 70% of e-commerce traffic coming from mobile devices, your checkout must perform flawlessly on small screens. The Checkout Page Customizer includes dedicated mobile controls, letting you optimize layouts, adjust touch targets, and streamline the mobile payment experience.
Preview your checkout on multiple device sizes, make mobile-specific adjustments, and ensure a frictionless experience regardless of how customers shop.
Express Payment Options
Modern shoppers expect modern payment options. The Checkout Page Customizer lets you configure the placement and prominence of express payment methods like Apple Pay, Google Pay, and Link. Position them above the fold for returning customers, or integrate them naturally into your checkout flow.
No Code Required
The Checkout Page Customizer uses a visual editor that requires zero coding knowledge. Drag and drop elements, adjust settings through intuitive controls, and preview changes in real-time. For merchants who want deeper customization, the underlying Liquid templates are fully accessible.
This means your marketing team can make checkout optimizations without waiting for developer resources. Test a new upsell offer in minutes, not weeks.
Available to Everyone
Here's the part that surprises merchants coming from other platforms: there's no "Checkout Customizer add-on" or premium tier requirement. Every CartOS subscription—from our starter plan to our highest tier—includes full access to the Checkout Page Customizer.
We believe the tools to optimize your business shouldn't be locked behind arbitrary paywalls. Your checkout is too important to leave generic, and you shouldn't need a $30,000 annual platform fee to make it your own.
