Ever get the feeling you’re checkout is losing you customers right at the critical moment of payment? You wouldn’t be alone.
Many checkouts still feel clunky, inconsistent, or confusing, but trying to change or customize them requires effort or resources you don’t have. So, you valiantly continue with your imperfect solution.
Whether you sell digital products, subscriptions, event tickets, or a combination of all three, it may be time to upgrade your checkout experience.
A well-designed checkout page UI can boost conversions, reduce friction, and give you more control, all without requiring a developer.
We have created this Checkout Page mini guide to help you choose a solution that works for both your business and your customers, enabling you to increase conversions and reduce checkout abandonment.
What is checkout page UI?
The checkout page user interface (UI) is the interface your customers interact with during the final step of their purchase journey; the checkout. It includes the layout, flow, visual elements, and behavior of the page(s) where they input their information, select payment options, and complete the order.
This is your last chance to make the sale, and a confusing or poorly designed UI can seriously derail it. Studies show that up to 70% of online shopping carts are abandoned, often due to issues related to the checkout process. That’s why UI matters.
Why checkout UI is important
Your product might be excellent, your price point spot-on, and your marketing working overtime for you. However, if your checkout isn’t straightforward, fast, and easy to use, people will leave before completing it, as the data above shows.
Some common problems highlighted with checkout UIs include:
- Long or unnecessary forms
- Confusing layout or flow
- Lack of familiar or convenient payment options
- Poor mobile or tablet experience
- No visual trust signals
- Inconsistent branding
- Costs and fees are not transparent or clearly shown
- Forced account creation ahead of payment
A great checkout UI should feel intuitive, fast, and trustworthy, and blend seamlessly with your website. It should also align with your brand and guide customers smoothly through the purchase process, all the way to the finish line.
Checkout page UI checklist
If you've decided it's time to upgrade your checkout, we're here to help you with a list of what to look for in a high-performing checkout UI.
1. Is it easy to set up and maintain?
We firmly believe you shouldn’t need a developer to launch or iterate your checkout page. Dependency on tech resources can massively slow down your ability to test, iterate, and improve over time. When looking for a platform, check for:
✅ No-code/low-code setup for non-technical people
✅ Pre-built components (payment links, modals)
✅ Clear documentation and a responsive customer support team
✅ Easy localization and multi-currency setup
✅ Easy setup without the need for a significant data migration
✅ Point and click customization for branding and forms
In short, businesses or teams without design or tech resources should be able to deploy and test updates quickly and be free to respond creatively to a rapidly changing market.
2. Is it mobile-first and fully responsive?
Over half of all e-commerce purchases now occur on mobile devices, so your checkout page UI needs to:
✅ Load quickly on 3G/4G connections
✅ Display forms and buttons correctly on all screen sizes
✅ Prioritize vertical stacking of input fields
✅ Include mobile-friendly keyboard triggers (e.g. number pad for credit card input)
✅ Use sticky call-to-actions (CTAs) for longer forms
It's been a long time since mobile was just a "nice to have"; it’s now the default for many users who shop on the move and at home on their phones and tablets. Failing to provide an optimized experience will cost you customers.
3. Is the layout intuitive and friction-free?
The ideal checkout flow should be intuitive and require minimal mental effort. Key UI principles to bear in mind include:
✅ Single-column layout options for total simplicity
✅ Logical step-by-step flow (Shipping > Billing > Review > Pay)
✅ Grouped, labeled input fields
✅ Use of spacing and contrast to guide the eye
✅ Avoiding surprise steps or unclear next actions
A good UI feels invisible and frictionless because it just works. It’s bad UI that will get you noticed (for all the wrong reasons).
4. Does it support the payment methods your users expect?
Payment preferences vary by region, device, and customer segment, so your checkout needs to cater to this spectrum. Your checkout UI should offer payment by:
✅ Cards (Visa, MasterCard)
✅ Wallets (Apple Pay, Google Pay, PayPal)
✅ Local methods (iDEAL, UPI, etc.)
✅ BNPL (Buy Now Pay Later) options (Klarna, ClearPay)
✅ Bank transfers or ACH
✅ Gift cards or coupon fields
✅ Invoicing and cash on delivery
When possible, displaying relevant options dynamically based on country and device will result in a seamless, tailored experience that maximizes conversion rates and wins you extra UI points!
5. Can it handle recurring payments or subscriptions?
If you sell memberships, recurring digital services, or retainers, then your checkout UI needs to be able to:
✅ Offer subscription frequency toggles (monthly/yearly)
✅ Offer free or discounted trial periods on subscriptions
✅ Show upcoming billing dates clearly
✅ Let customers manage billing in the post-checkout UI, such as a customer portal
✅ Explain cancellation and renewal terms up front
Having a platform that supports friction-free subscription and recurring payment functionality reduces churn and helps you build ongoing customer relationships.
6. Is the branding and styling consistent with your site?
When users arrive at checkout, they shouldn’t feel like they’ve been handed over to a different company. The user interface should:
✅ Match your brand’s colors, fonts, and tone
✅ Include your logo prominently
✅ Use your domain or a white-labeled one
✅ Include custom confirmation and success screens
Consistency in branding, from start to finish, builds trust and confidence, making you look professional. Disjointed or clunky experiences erode it and cost you sales.
7. Is it secure, and does it feel safe?
Users don’t just want a technically secure checkout; they want visual reassurance that it’s secure. Your UI should:
✅ Include trust signals (SSL badge, lock icon, “Secure checkout” language)
✅ Show recognized payment logos
✅ Reassure users that their payment details are never stored
✅ Avoid pop-ups that feel sketchy
Trust is a vital part of the checkout UI, with 19% of abandonments occurring because buyers sense that the checkout is not trustworthy.
8. Is the form behavior smart and helpful?
Forms are where users often get stuck or frustrated. A thoughtful checkout UI can solve this, providing clarity and sparing them unnecessary steps. Consider a platform that offers:
✅ Autofill support for name, email, and address
✅ Field validation in real time
✅ Clear, friendly error messages
✅ Auto-formatting for phone numbers, card data, etc.
✅ Conditional formatting options, so you only show fields when relevant
✅ Progress indicators for multi-step flows
Every second or effort saved reduces drop-offs by annoyed buyers who liked your product, but not your payment page.
9. Can it support flexible checkout experiences?
Checkout shouldn't be limited to those visiting your website. It's vital to be able to reach people from the many different places they connect with you. You'll want to be able to:
✅ Send payment links via email, DM, or SMS
✅ Display links to hosted payment pages from social media bios
✅ Embed checkout in a product page or modal.
✅ Use a pop-up for instant purchases.
✅ Generate QR codes for use on posters or other forms of publicity
The more flexible the delivery, the more use cases you unlock.
10. Can it scale with your business?
Make sure your checkout UI and payment infrastructure can handle:
✅ Peak traffic (launches, campaigns, tickets going on sale)
✅ Multiple currencies and different tax rules by location
✅ Multi-language support
✅ Role-based access for your team members
✅ Analytics integrations for insight, testing, and optimization
You shouldn't need to keep moving platforms whenever your business takes a big step forward. Ensure your solution supports your growth.
11. Does it support analytics, testing, and optimization?
Great UIs continually evolve to meet your customers' shifting behavior over time. To faciliate continous improvement, your solution should support:
✅ A/B testing (button copy, layout, steps)
✅ Conversion funnel tracking
✅ Form abandonment reporting
✅ Integration with tools like Google Analytics, Hotjar, or Segment
It's important to iterate based on real behavior, not guesswork. Your theories may not align with reality, so statistical insight is crucial.
12. Is the pricing transparent and sustainable?
Looking beyond just the UI features the platform or solution offers is very important. When sourcing a solution, ask:
✅ What, if any, are the per-transaction fees?
✅ Are there add-ons for features like subscriptions or custom domains?
✅ Do support or API access incur hidden charges?
✅ Is pricing flat or tiered with growth?
The best checkout UI won’t just convert, it’ll scale profitably and not penalize you with high fees for making more sales as you grow.
13. Is it fast and accessible?
Load speed, performance, and accessibility are sometimes overlooked, yet they are critical. A fast, inclusive checkout UI should:
✅ Load in under 2 seconds
✅ Use semantic HTML for screen readers
✅ Support keyboard navigation
✅ Maintain color contrast ratios
✅ Avoid flashing animations or motion triggers
These changes not only benefit your buyers but also enhance your SEO and ensure compliance with relevant laws.
