One-Page Checkout in Magento 2: What to Optimise for Higher Conversions

Checkout is where the sale is won or lost. You might have a stunning Magento 2 store, plenty of visitors, and products that people actually want, but all that becomes irrelevant if your checkout process slows them down. Shoppers abandon their carts quickly when the process becomes cumbersome—especially in B2C e-commerce. That’s not just speculation; the data confirms it.  Magento 2’s one-page checkout gives you a strong foundation, but to be honest, the default option rarely delivers the best results. If you want to increase conversions, you need to go beyond the basics—make it more user-friendly, faster, and more reliable. Don’t just set it up and forget about it. Analyse real data, adjust, and keep optimising.  This guide focuses on exactly what you should improve in Magento 2’s one-page checkout. It’s designed to help you convert more shoppers, reduce cart abandonment, and create a smoother buying experience—drawing on real-world insights and proven methods from a Magento agency like the team at Ingold Solutions.

Why One-Page Checkout is Important in Magento 2 

Magento 2 simplifies the purchase process by using the one-page checkout. Instead of hopping from one page to another, Magento 2 make customers complete their order purchase in a single streamlined interface.  However, “one page” does not automatically mean “optimised.” If the checkout loads slowly, asks for unnecessary information, or lacks trust signals, customers will still abandon their carts. Studies from Baymard Institute show that: 

• Over 22% of users abandon checkout due to long or complicated processes

• 18% leave because they don’t trust the site with their payment details

• 17% abandon due to forced account creation

Magento 2 gives merchants flexibility—but optimisation is where conversions are truly won. 

1. Reduce Friction: Ask Only for Essential Information

One of the most common Magento checkout mistakes is collecting too much data.  What to optimise: 

• Remove non-essential fields (company name, second address line, fax, etc.) 

• Avoid redundant billing and shipping fields 

• Use smart defaults (auto-select country, region, shipping method) 

Every extra field adds hesitation. A Magento agency experienced in UX optimisation will typically audit checkout fields and remove anything that does not directly support fulfilment, compliance, or payment.  Pro tip: For B2C stores, fewer fields almost always outperform detailed forms. 

2. Enable Guest Checkout by Default

Forced account creation is one of the biggest conversion killers.  Magento 2 supports guest checkout, but many stores still push registration too early.  Best practice: 

• Enable guest checkout as the default option 

• Offer account creation after purchase 

• Use “Create account with one click” post-checkout 

This approach respects user intent. Many customers want speed—not commitment.  A professional Mageto agency will always recommend optimising guest checkout before adding advanced CRO features.

3. Optimise Checkout Speed (Performance Is Conversion)

Speed is not a technical vanity metric—it directly impacts revenue.  According to Google: 

• A 1-second delay can reduce conversions by up to 20% 

Key Magento 2 checkout performance optimisations: 

• Enable full-page cache and Varnish correctly 

• Optimise JavaScript bundling for checkout 

• Remove unused checkout extensions 

• Optimise API calls (especially shipping & payment providers) 

• Use lazy loading only where appropriate 

Checkout is JavaScript-heavy by nature. Poorly optimised extensions or third-party scripts can slow it down dramatically.  This is where working with an experienced Magento agency like Ingold Solutions makes a measurable difference—because checkout performance requires both technical Magento expertise and CRO understanding.

4. Simplify Shipping Method Selection

Confusing shipping options increase hesitation and drop-offs.  What works best: 

• Preselect the most common shipping method 

• Clearly display delivery times and costs 

• Avoid forcing users to “calculate shipping” manually 

• Hide irrelevant shipping methods based on location 

For international Magento stores, smart shipping logic is essential. Customers should instantly understand: 

• When their order arrives 

• How much it costs 

• Whether tracking is included 

Clear shipping information builds confidence—and confidence converts. 

5. Payment Method Optimisation: Fewer Choices, Better UX

More payment options do not always mean higher conversions.  Magento 2 payment best practices: 

• Show only relevant payment methods per country 

• Prioritise fast payment options (PayPal, Apple Pay, Klarna, credit cards) 

• Avoid redirect-heavy payment flows 

• Clearly display security and payment logos 

Magento 2 allows deep customisation of payment logic. A Magento agency can configure: 

• Country-based payment visibility 

• Order value–based payment rules 

• B2C vs B2B payment differentiation 

The goal is clarity, not overload. 

6. Build Trust at Checkout (Visual & Psychological)

Trust is often the silent conversion factor.  Customers may love your products—but checkout is where scepticism peaks.  Trust elements to optimise: 

• SSL indicators and secure checkout messaging 

• Visible payment provider logos 

• Clear return and refund policy links 

• Customer support contact info 

• Delivery guarantees 

Magento checkout should visually communicate “this store is safe.”  Ingold Solutions often integrates trust elements subtly into checkout UI—without clutter—so customers feel reassured without distraction. 

7. Mobile Checkout Optimisation Is Non-Negotiable

More than half of Magento B2C transactions now happen on mobile devices.  Yet many Magento checkouts still feel “desktop-first.”  Mobile optimisation checklist: 

• Large, tappable buttons 

• Auto-open numeric keyboards for phone and SIP fields 

• Sticky “Place Order” button 

• Minimal scrolling 

• Autofill and address suggestions 

Magento 2 is mobile-capable—but mobile optimisation requires deliberate UX work.  Any serious Mageto agency should test checkout on real devices, not just emulators. 

8. Smart Error Handling & Inline Validation

Checkout errors are inevitable—but how they’re handled determines success.  What to improve: 

• Inline field validation (not error messages after submission) 

• Clear, human-readable error messages 

• Preserve entered data after errors 

• Highlight errors visually, not aggressively 

Poor error handling makes customers feel punished. Good error handling feels helpful. 

9. Checkout Extensions: Use Less, Not More

Magento’s ecosystem offers countless checkout extensions—but more is rarely better.  Each extension: 

• Adds JavaScript 

• Increases conflict risk 

• Can slow down checkout 

A strategic Magento agency approach focuses on: 

• Native Magento functionality first 

• Custom lightweight development when needed 

• Removing outdated or redundant modules 

At Ingold Solutions, checkout optimisation often starts with extension cleanup, not new installs.

10. Measure, Test, Improve: Data-Driven Checkout Optimisation

Optimisation without data is guesswork.  Magento 2 allows deep analytics integration when set up correctly.  What to track: 

• Checkout step drop-off rates 

• Payment method usage 

• Shipping method abandonment 

• Mobile vs desktop conversion gaps 

• Page load time during checkout 

A/B testing checkout changes—when done carefully—can produce significant gains over time.  This is where a long-term partnership with a Magento agency pays off: optimisation is not a one-time task, but an ongoing process.
