Mobile checkout page design & Checkout Usability 101 (with best examples)

Welcome to Chapter 5 of the Ultimate Guide to Mobile App Design with Simicart! In this chapter, we’re focusing on the critical aspects of Mobile Checkout Page Design & Checkout Usability 101. If you’re looking to optimize the checkout process and make it seamless for your users, you’re in the right place.

We’ll guide you through the best practices for designing an intuitive, mobile-friendly checkout page that not only enhances user experience but also boosts conversions. Let’s dive into the key elements that will help you create a checkout experience that’s fast, secure, and user-centric.

What makes an amazing mobile checkout page design?

An amazing mobile checkout page design is crucial for enhancing user experience and increasing conversion rates. Here are the key elements that contribute to an effective mobile checkout design:

• Responsive Layout: Ensure the checkout page is fully responsive, adapting seamlessly to various screen sizes and orientations. This allows for a consistent user experience across devices, especially as mobile shopping continues to rise.
• Simplified Form Fields: Limit form fields to essential information only, such as name, address, and payment details. Use autofill features to expedite the process and reduce user input effort.
• Touch-Friendly Buttons: Larger checkout button design with ample spacing to accommodate touch inputs, ensuring that users can easily tap without accidentally selecting the wrong option. A common guideline is to make buttons at least 44 pixels in size.
• Clear Call-to-Action (CTA): Use prominent, action-oriented text for buttons like “Complete Purchase” or “Checkout” to create a sense of urgency. Position these buttons in easily accessible areas, preferably at the bottom of the screen
•  Fast Loading Times: Optimize images and scripts to ensure quick loading times for the checkout page. Slow loading can lead to cart abandonment, so speed is essential for retaining customers.

46% of respondents in a Google and Heart+Mind Strategies study prefer using smartphones for the entire purchase process. Ensure a seamless mobile checkout to let them complete orders effortlessly on their phones.

24. Add Paypal checkout shortcut

Users expect a seamless payment process when shopping online. Providing third-party payment options like Paypal can simplify the payment process and increase the sense of security. Checkout with Paypal only requires two steps to complete, bypassing entering credit card information and shipping details. By minimizing the number of manual steps users have to take, such as filling out additional forms, the app saves time and energy for users to complete a purchase.

25. Collapse the coupon code field

Providing coupon code at the point of checkout is a popular tactic to increase sales in online shopping. However, when the option to use coupons during checkout is made too prominent, it easily distracts users from completing their purchases. Many users don’t have the coupon codes to redeem and leave checkout in hunt for one, which ends up not returning to complete transactions. If your app have coupon and discount codes available, make the coupon less prominent by collapsing the field to minimize distraction from the checkout flow. 

26. Show floating checkout button

The more you nudge users towards the checkout funnel, the better your chances are of a completed purchase. Make the next step call to action prominent by showing the floating checkout button. This ensures that there’s always one button available for shoppers to proceed to checkout regardless of where they scroll to on the cart page.

27. Provide an option to review order details after purchase

After completing a purchase, users want the ability to check order details to make sure that no mistake has been made. Provide an option to review all necessary purchase information for users to verify the order right away.

Guide to App Usability

In the prior chapters of this guide we have covered highly specific design principles across key aspects of an ecommerce app, including search, form entry, product catalog, customer account, cart and checkout. Beside the presented principles, these general usability recommendations cater to mobile user needs that brands should definitely consider when designing for an ecommerce app.

28. Allow users to continue shopping after adding an item to cart

Adding an item to cart should not force users to the cart page. It causes friction for users who look to add multiple items to cart. Every time an item is added, it takes extra steps for users to go back to shopping. Instead, provide feedback to confirm that the item has been added to cart and allow users to continue shopping.

29. Allow users to go back easily in one step

As users browsing the app, they want the ability to go back and forth in a single step of the app flow. Don’t get users frustrated by forcing them to start all over from the home screen, which can result in losing any unsaved user data. Leverage back functionality in your app so that users can easily go back in one step.

30. Show clear visual feedback (toast)

Lack of feedback after an action leaves users confused whether the app has processed. After users take an action in your app, respond with a brief message that inform them if the action is completed, which does not interrupt their experience while eliminating the guesswork for users.
