When a potential customer makes it all the way to checkout, you know they’re interested in your product and have high purchase intent. By optimizing your checkout process, you can get more confirmed orders and fewer drop-offs.
According to Baymard’s 2026 cart abandonment data, $260 billion of lost orders could be recovered just with better checkout flows.
“Checkout is a game, and friction is the enemy,” says David Cost, VP of ecommerce at Rainbow Shops. “Anything we can do to eliminate that friction helps us win.”
This guide explains which checkout changes matter most in 2026 and how Shopify can help you implement them without introducing new friction or compliance risk.
What is ecommerce checkout optimization?
The goal of checkout optimization is to remove any hurdles that might stop a potential customer from completing an order. These sources of customer friction could be complicated checkout processes, not enough payment options, or unexpectedly high shipping rates. Checkout optimization covers the design, functionality, speed, clarity, and trust of the checkout flow.
When you optimize your checkout, you evaluate:
- Form design. Are forms short, intuitive, and easy to complete with autofill, clear labels, and error messages?
- Payment options. Do customers see trusted, relevant payment methods?
- Shipping cost transparency. Are shipping costs, taxes, fees, and delivery timelines shown before the final step?
- Mobile usability. Is the checkout easy to use on mobile, with readable text, and large buttons?
- Guest checkout. Can customers complete their purchase without creating an account?
- Mobile wallet support. Can shoppers check out quickly with Shop Pay, Apple Pay, Google Pay, or PayPal?
- Speed. Do checkout pages load quickly?
- Localization. Does checkout adapt to the customer’s country, language, currency, taxes, shipping methods, and local payment options?
- Post-checkout recovery. Do you have abandoned cart emails, SMS reminders, or saved-cart links to bring shoppers back?
Why ecommerce checkout optimization matters
According to Baymard’s data, the average cart abandonment rate is 70.22%. High extra costs (shipping, tax, fees), complicated checkout processes, not enough payment options, and a lack of trust in the website’s security are among the top reasons online shoppers reported not completing a checkout.
By optimizing the checkout process with better design, large ecommerce sites can see a 35.26% increase in conversion rate. “By tidying up the pages and flows closer to the transaction, you can get more sales with the same traffic, and way more sales when you open the traffic floodgates,” says Josh Garofalo, founder of Sway Copy.
The biggest causes of checkout friction
Baymard’s 2026 study found the biggest causes of checkout abandonment are:
- I was browsing/not ready to buy (43%)
- Extra costs too high (shipping, etc.) (39%)
- Delivery was too slow (21%)
- I didn’t trust the site with my credit card (19%)
- Had to create an account (19%)
- Too long/complex checkout process (18%)
- Returns policy wasn’t satisfactory (15%)
- Website had errors/crashed (15%)
- I couldn’t see total order cost upfront (14%)
- Not enough payment methods (10%)
- My credit card was declined (8%)

Optimize your ecommerce checkout flow by addressing the main reasons for checkout abandonment:
1. Simplify the flow and remove unnecessary fields
On average, the checkouts in Baymard’s research have five steps and 11 form fields, but its user experience (UX) research suggests that many sites need only eight fields.
Fewer steps don’t automatically mean better UX; lower cognitive effort does. In general, you should only request information needed to fulfill the order. It might be nice to have a customer’s birthday for future targeting, but not at the risk of causing someone to exit the purchase.
To simplify the checkout flow:
- Hide optional fields like separate shipping and billing addresses
- Combine inputs, like “First name” and “Last name” merged into one “Name” field
- Use address auto-complete
When Stellar Eats switched to Shopify’s one-page checkout, which pre-fills billing and shipping information, they saw conversions increase by 3.5% with no other major site changes.
“One-page checkout is a game changer for reducing friction—especially with shipping automatically calculated right in front of you,” says Emma Kula, co-founder and chief product officer of Stellar Eats.
2. Offer guest checkout and accelerated checkout
“The site forced me to create an account” is responsible for 19% of all abandoned checkouts. To reduce account creation friction, consider offering:
- Guest checkout option. Reduce resistance for first-time buyers by letting them check out without creating a password
- Accelerated checkout. Eliminate manual entry by using stored identity or payment details in digital wallets like Shop Pay, Apple Pay, Google Pay. These wallets also have extra customer authentication methods—like passwords or biometric logins—to block a common entry point for ecommerce fraud.
Shop Pay can lift conversion by up to 50% versus guest checkout and outperform other accelerated checkouts by at least 10%.
Apparel brand Princess Polly turned to Shop Pay when they began working on optimizing their checkout. Shop Pay helped Princess Polly reduce checkout completion times by 7.6% storewide. They also increased conversion rates by 4.1% for buyers with an existing Shop Pay session.
“The results were beyond our expectations,” says Melanie Huang, the brand’s ecommerce manager. “The increase in conversions and overall orders showed us the power of a seamless checkout process, affirming our decision to prioritize customer experience.”
3. Make pricing transparent before the final step
Surprise shipping, duties, taxes, and fees aren’t a minor annoyance, they’re a direct cause of abandonment. Extra costs are the second-biggest driver of exited checkouts.
To reduce checkout abandonment because of unexpected shipping costs:
- Surface shipping estimates early
- Explain free shipping thresholds before checkout
- Use duty and tax inclusive pricing for international shoppers
By streamlining online checkout, Stellar Eats was able to overcome the checkout challenges that come with convincing customers to buy consumer packaged goods online.
“We leverage a free shipping threshold to help push [customers] to convert and really appreciate that they become aware of it at a critical moment in the buyer’s journey with one-page checkout,” says Stellar Eats’ Emma Kula.
4. Offer payment methods customers actually want
Limited payment options drive 10% of all abandoned checkouts. Give customers more options with a payment gateway that supports multiple payment methods like:
- Credit or debit card
- Digital wallets like Apple Pay or Google Pay
- Shopping apps like Shop Pay
- Buy now, pay later
- Loyalty points
If you sell internationally, you should consider which payment methods are popular locally. “We found through a lot of third-party research that payment methods really matter based on region,” says Dylan Feiner, senior product manager at Ruggable.
For example, account-to-account (A2A) payments account for just 4% of ecommerce transactions in the US, but 23% of all online orders in Latin America. Enable A2A options like Pix, DiMo, or Plin for customers in that market, and monitor the impact on checkout conversion rates.
5. Optimize relentlessly for mobile checkout
Checkout friction on small screens is especially expensive: Statista’s 2026 research shows mobile shoppers account for 71% of all online orders.
Take a mobile-first approach with checkout optimization strategies like:
- Fewer fields
- Larger tap targets
- Fast load times
- Visible order summary
- Digital wallet buttons
Shopify Checkout—the world’s highest-converting checkout—offers all of these mobile-friendly features. The platform is optimized for speed and displays a visual order summary with finger-friendly buttons. Shop Pay also pre-fills saved email, shipping, and payment details at checkout.
Apparel brand Serge Blanco used Shopify Checkout features to improve their mobile ecommerce checkout experience.
“What changed very quickly was how simple checkout became,” says director of ecommerce Julien Fournier. “That drove conversion rates up directly, especially on mobile.”
6. Build trust and reduce security-related hesitation
Lack of trust is the reason behind 19% of all abandoned checkouts.
Trust building doesn’t just help reduce abandonment: it can build customer loyalty and support price increases. Salsify’s 2026 consumer research shows that 68% of shoppers have paid more for a product in the past year because they trust the brand.
Trust signals that actually matter at checkout:
- Recognizable payment options. Payment processor logos are already recognizable to the customers who use them.
- Transparent data collection. Attentive’s 2026 report found that 71% of customers are taking action to protect their privacy. Let customers opt into SMS or email marketing at checkout, and enable double opt-in to add an extra verification layer.
- Clear return policies. Some 81% of shoppers read a return policy before they buy. Summarize your return window, eligible products, and refund options at checkout.
- Shipping windows. Almost three-quarters of shoppers say that estimated delivery dates influence their purchase decisions. Shop Promise displays delivery dates at checkout and gives Shop Cash to customers if an eligible order arrives late.
EasyStandard was dealing with slow shipping speeds, order errors, and billing discrepancies with their previous third-party logistics (3PL) provider, so the company turned to the Shopify Fulfillment Network (SFN).
This gave them access to Shop Promise, which meant that customers browsing product pages and checkout could see real-time delivery guarantees. The result: a 19% increase in conversion with 93% on-time delivery with SFN.
7. Localize checkout for international buyers
Cross-border ecommerce sales are expected to reach $4.81 trillion by 2032, as 59% of shoppers already buy from retailers outside of their home country, per DHL’s 2025 report.
Go beyond basic translation with localized checkout that includes tailored:
- Currencies. DHL’s report found prices in their local currency would encourage 55% of global shoppers to buy from an international retailer.
- Duties. Some 41% want to see clear guidance on customs charges.
- Shipping expectations. Name any trusted delivery partners in that area: 40% of shoppers find this influential when buying internationally.
SWATI uses Shopify Markets to optimize international checkout. One storefront dynamically adjusts to display local currencies and translated copy for shoppers in 119 countries. Since signing up, they’ve recorded a 45% revenue increase in key markets.
8. Customize checkout without breaking performance
Run a conversion rate optimization (CRO) audit to see why potential customers exit checkout. If the answer is something a default checkout doesn’t address, explore customization options.
Remember that checkout customization shouldn’t create fragility, lag, or compliance headaches. For every 100 milliseconds slower a store loads, conversion tends to be about 3.5% lower.
Almost 80% of Shopify stores pass Core Web Vitals. Combine that foundation with Shopify Checkout and use Checkout Extensibility to:
- Customize branding
- Display loyalty program reminders
- Apply upsell logic
- Reinforce return policies or guarantees
- Offer pre-orders
- Stack discount combinations
Canadian travel brand Monos turned to Checkout Extensibility in an effort to prioritize speedy checkouts during their peak season.
“Faster checkouts make buyers more confident in their purchases, which helps us improve conversion and reduce checkout abandonment,” says senior ecommerce developer Jake Fox.
Alongside improving checkout speed, Checkout Extensibility also saves the Monos team more than 10 hours in development time each month.
9. Use post-checkout and abandonment recovery to capture missed revenue
“I wasn’t ready to buy” is the biggest driver of abandonment. Checkout recovery campaigns can nurture those shoppers after they leave through email, SMS, or a combination of the two.
Klaviyo’s 2026 benchmarks show that cart recovery emails have a 6% click rate compared to 1.6% for generic campaigns. They also average $6.77 revenue per user, which is much higher than the 20¢ average.
SMS campaigns show the same trend: Klaviyo reports an average revenue per recipient of $4.48 for recovery SMS campaigns versus 32¢ for campaigns.
Shopify Messaging handles the abandoned checkout flow natively, displaying the exact items a customer left behind. Pair it with Shopify Flow to add conditions and timing logic to email or SMS recovery campaigns.
For example, you could:
- Trigger a discount offer only for carts above a set value
- Adjust the send window from the 10-hour default to test whether timing influences recovery rates
- Exclude people who already received a cart recovery email in the past 14 days
For high consideration or high-value purchases, you could also use Shopify Flow to send an internal message to your sales team. Have them reach out with a personalized message to customers who still don’t buy through the automated campaign.
10. Measure checkout performance and run experiments
Optimization isn’t a one-time redesign. Use website analytics to monitor how optimizations impact checkout completion rate.
Segment that checkout data to find discrepancies between:
- Desktop versus mobile devices
- New versus returning customers
- Logged in versus logged out customers
Post-purchase surveys can reveal what converted users liked, while abandonment surveys and recordings reveal what blocked others.
If error rates are high because shoppers incorrectly type their shipping address, for example, enable autocompletion. Track sessions post-fix to see whether that helps address conversion gap.
Fold checkout recovery performance into your analysis. How many customers did your campaigns bring back? What commonalities do high-converting campaigns share?
For example, if a checkout abandonment message sent after 12 hours recovers 10% of abandoned carts, you might test a shorter recovery window. Test whether this is true in other parts of the ecommerce checkout process, like quickly prompting people to retry payment details if their original method fails.
