Why Checkout Optimisation Matters for Conversion Rates
The checkout experience is the final hurdle between browsing and buying. According to the Baymard Institute, the average large-sized e-commerce site can gain a 35.26% increase in conversion rate through better checkout design. That’s a significant revenue boost from optimising a single part of your customer journey.
Let’s look at some eye-opening statistics that demonstrate why checkout optimisation should be a priority:
Checkout Issue | Abandonment Rate |
Unexpected costs (shipping, taxes, fees) | 48% |
Forced account creation | 26% |
Complicated checkout process | 22% |
Couldn’t calculate total order cost | 21% |
Website security concerns | 19% |
These numbers reveal a clear opportunity: by addressing these common checkout pain points, you can significantly reduce abandonment rates and capture more sales from the traffic you already have.

5 Key Elements of a Seamless Checkout Experience
Creating a frictionless checkout process requires attention to several critical elements. Let’s explore the five most important components that contribute to a seamless checkout experience.

1. Guest Checkout Option
Forced account creation is responsible for 26% of cart abandonments. Offering a guest checkout option removes this significant barrier to purchase. While customer accounts provide valuable data and streamline future purchases, making them optional rather than mandatory is the best approach.
2. Mobile Responsiveness
With over half of all e-commerce traffic coming from mobile devices, your checkout must be fully optimised for smartphones and tablets. This means large, tappable buttons, simplified forms, and responsive design that adapts to any screen size without compromising functionality.
3. Progress Indicators
Customers want to know where they are in the checkout process and how many steps remain. Progress indicators leverage the Zeigarnik effect—our psychological tendency to complete unfinished tasks—making customers more likely to continue through all checkout stages.
4. Multiple Payment Options
Different customers prefer different payment methods. Offering variety—including credit/debit cards, digital wallets (Apple Pay, Google Pay), and buy now, pay later options—ensures you’re not losing sales due to limited payment choices. Studies show 13% of shoppers abandon carts when their preferred payment method isn’t available.
5. Trust Indicators
Security concerns cause 19% of checkout abandonments. Displaying trust badges, SSL certificates, and secure payment icons reassures customers their data is safe. Clear return policies and customer testimonials further build confidence during this critical decision-making moment.
Bonus: Order Summary
Transparency about costs is crucial, as unexpected fees cause 48% of abandonments. A clear order summary showing product costs, shipping, taxes, and any additional fees eliminates surprises and builds trust throughout the checkout process.
Creating a Seamless Checkout Experience on Shopify
Shopify offers robust checkout customisation options that can help you implement the key elements we’ve discussed. Let’s explore how to optimise your Shopify checkout process step by step.

Editing Checkout Templates with Shopify Liquid
Shopify Plus merchants can customise their checkout using Liquid, Shopify’s templating language. Here’s how to implement some key optimisations:
Note: Checkout customisation with Liquid is only available on Shopify Plus plans. Standard Shopify plans have limited checkout customisation options through the theme editor.
To add a progress indicator to your checkout, add this Liquid code to your checkout.liquid file:
{% if checkout.step_one? %}
<div class=”checkout-progress”>
<span class=”step active”>Information</span>
<span class=”step”>Shipping</span>
<span class=”step”>Payment</span>
</div>
{% elsif checkout.step_two? %}
<div class=”checkout-progress”>
<span class=”step completed”>Information</span>
<span class=”step active”>Shipping</span>
<span class=”step”>Payment</span>
</div>
{% else %}
<div class=”checkout-progress”>
<span class=”step completed”>Information</span>
<span class=”step completed”>Shipping</span>
<span class=”step active”>Payment</span>
</div>
{% endif %}
Recommended Shopify Checkout Apps
Even without Shopify Plus, you can enhance your checkout experience with these powerful apps:
1. CartHook
CartHook allows you to add post-purchase upsells and one-click upsells to your checkout flow, increasing average order value while maintaining a streamlined experience.
- Post-purchase upsell funnels
- A/B testing capabilities
- Analytics dashboard
2. ReConvert
ReConvert transforms your thank you page into a powerful conversion tool with personalised offers, surveys, and reorder buttons to boost customer lifetime value.
- Thank you page customisation
- Product recommendations
- Customer feedback collection
Reducing Abandoned Carts with Email Recovery
Shopify’s built-in abandoned cart recovery emails can help recapture lost sales. Here’s how to optimise them:
- Go to Settings > Checkout in your Shopify admin
- Scroll to “Abandoned checkouts” and enable automatic emails
- Customise the email timing (6-10 hours after abandonment is optimal)
- Personalise the email content with the customer’s name and cart items
- Include a clear, direct link back to their checkout
- Consider adding a limited-time discount to create urgency

Creating a Seamless Checkout Experience on WordPress/WooCommerce
WordPress with WooCommerce offers extensive customisation options for your checkout process. Here’s how to optimise it for maximum conversions.

Recommended WooCommerce Plugins
These plugins can significantly enhance your WordPress checkout experience:
WooCommerce Checkout Field Editor
This official WooCommerce extension allows you to add, edit, or remove checkout fields without writing code. Streamline your forms by removing unnecessary fields or adding custom ones specific to your business needs.
CheckoutWC
This premium plugin completely redesigns the WooCommerce checkout page with a multi-step or one-page design, order bumps, custom thank you pages, and mobile optimisation built-in.
WooCommerce One Page Checkout
Transform any page into a streamlined checkout page where customers can select products, enter their details, and complete their purchase all on a single page.
Customising Checkout Pages with CSS/HTML
For more advanced customisations, you can use CSS and HTML snippets. Here’s a useful example to create a cleaner two-column checkout layout:
/* Add this to your theme’s style.css or Customiser CSS section */
@media (min-width: 768px) {
.woocommerce-checkout form.checkout {
display: flex;
flex-wrap: wrap;
}
.woocommerce-checkout form.checkout .col2-set {
width: 58%;
margin-right: 2%;
}
.woocommerce-checkout form.checkout #order_review_heading,
.woocommerce-checkout form.checkout #order_review {
width: 40%;
float: right;
}
}
Payment Gateway Optimisation
WooCommerce supports numerous payment gateways. Here’s how to optimise them:

- Install multiple payment gateways to offer variety (Stripe, PayPal, Amazon Pay)
- Enable express checkout options like Apple Pay and Google Pay
- Consider adding buy now, pay later options like Klarna or Afterpay
- Optimise payment gateway loading speed by minimising unnecessary scripts
- Display payment security badges near payment options
For optimal performance, use this code to load payment gateway scripts only on checkout pages:
add_action(‘wp_enqueue_scripts’, ‘optimize_checkout_scripts’, 99);
function optimize_checkout_scripts() {
if (!is_checkout()) {
// Remove payment scripts on non-checkout pages
wp_dequeue_script(‘stripe’);
wp_dequeue_script(‘woocommerce-gateway-paypal-express-checkout’);
}
}
3 Common Checkout Pitfalls to Avoid
Even with the best intentions, these common mistakes can undermine your checkout optimization efforts. Here’s what to avoid:

1. Hidden Fees and Surprise Costs
Unexpected shipping costs, taxes, or processing fees revealed only at the final checkout step are the #1 cause of cart abandonment (48%). Always display all costs upfront or provide a shipping calculator early in the shopping process.
2. Excessive Form Fields
Every additional field in your checkout form increases friction. Do you really need the customer’s phone number, date of birth, or company name? Eliminate all non-essential fields and use autofill where possible to streamline the process.
3. Lack of Mobile Optimisation
A checkout that works perfectly on desktop but breaks on mobile will cost you sales. Common mobile issues include tiny form fields, difficult-to-tap buttons, and keyboard types that don’t match input requirements (e.g., numeric keyboard for phone numbers).
Shopify vs WordPress Checkout Customisation Capabilities
Both platforms offer powerful checkout customisation options, but they differ in several key aspects. Understanding these differences will help you choose the right platform for your needs or make the most of your current platform.

Feature | Shopify | WordPress/WooCommerce |
Ease of Setup | Easier out-of-the-box setup with fewer options | More complex initial setup but highly customisable |
Checkout Customisation | Limited on standard plans; extensive on Shopify Plus | Fully customisable at all levels with plugins or code |
Payment Gateways | Shopify Payments + 100+ integrations (with transaction fees for non-Shopify Payments) | Unlimited options with no additional transaction fees |
Mobile Optimisation | Excellent built-in mobile optimisation | Depends on theme and plugins; may require additional work |
Development Skills Required | Minimal for basic stores; Liquid knowledge for advanced customisation | More technical knowledge required for optimal results |
Maintenance | Managed platform with automatic updates | Self-managed; requires regular updates and maintenance |
“The best platform depends on your specific needs. Shopify offers simplicity and reliability with less maintenance, while WordPress provides unlimited customisation potential for those willing to invest more time or resources in development.”
