E-commerce
April 14, 2026
Optimizing e-commerce checkout to reduce cart abandonment, is not just about adding a follow-up email. It is first and foremost about removing the friction that prevents an already interested buyer from completing their order.
This is a huge issue. Shopify notes that in 2024, according to Baymard Institute, 70,19 % of online carts were abandoned instead of being purchased. Baymard also estimates that by simply improving the flow and design of checkout, 260 billion dollars in lost orders can be recovered in the United States and Europe.
In other words, a significant part of growth is not necessarily found in more traffic. It is found in a checkout that is simpler, clearer, more reassuring, and faster.
What you will clarify : why shoppers really abandon at the payment stage.
What you will be able to do : improve displayed costs, payment methods, mobile, reassurance, the data-entry journey, and recovery sequences.
To connect with : the e-commerce funnel, analytics and the mobile-first strategy.
So the real question is not “how do we bring back cart abandoners?”. The real question is first : “why do we push them to leave just before purchasing?”
Summary
Checkout is where conversion is confirmed or falls apart
A visitor who reaches checkout has already crossed several barriers: discovery, interest, comparison, adding to cart. They have shown real intent. That is precisely why abandonment at this stage is so costly.
Shopify reminds us that an apparently modest increase in the conversion rate can have a very significant financial impact. The example given in their guide is telling: with 125,000 monthly visitors, an average basket of 100 dollars and an improvement of only 0.5 percentage point in the conversion rate, monthly revenue can grow by 62,500 dollars.
The checkout must therefore be treated as a full-fledged business asset. Not as a simple transactional page that is left in place as long as it “sort of works.”
Key idea: the stronger the purchase intent, the more every visible or invisible friction becomes costly.
Why customers abandon their shopping cart
Shopify synthesises very well the main reasons for abandonment based on Baymard Institute. The most frequent reasons are well known, but they remain under-addressed in many stores.
Too high additional costs : 48 % of shoppers abandon because of unexpected fees, taxes, or shipping costs.
Account creation required : 26 % abandon when they are forced to create an account.
Concerns about payment security : 25 % leave checkout due to a lack of trust.
Shipping too slow : 23 % consider the delivery time insufficient.
Checkout too complex : 22 % abandon because the process is too long or too complicated.
Total cost not clear enough : 21 % want to see the total earlier.
Unsatisfactory return policy : 18 %.
Technical errors : 17 %.
Insufficient payment methods : 13 %.
Stripe confirms the same logic: unexpected costs, a complicated process, poor performance, lack of trust, limited payment options, forced account creation, an unclear return policy, and product unavailability are among the major causes of abandonment.
The first conclusion is simple: a large part of abandonment is not “normal.” It is caused by decisions about design, messaging, structure, or infrastructure.
Cost transparency is the first optimization
The number one cause of abandonment remains price surprise. The shopper thinks they have understood the price, then discovers at checkout shipping fees, taxes, or other costs that completely change the perception of the offer.
Stripe recommends a simple approach: show potential costs as early as possible, or at a minimum offer a clear estimator very early in the journey. Shopify takes the same view, recommending that you display a running total including fees as early as possible.
What this means in practice
Show shipping fees before the final checkout, not only on the last screen.
Use clear free-shipping thresholds that are consistent with the average cart value.
Avoid opaque extra fees that seem to appear at the last moment.
Show the estimated order total as soon as the cart or mini-cart.
A transparent checkout can sometimes convert better than an “aggressive” checkout that delays information. When the buyer feels trapped, trust collapses very quickly.
Simplify the journey: fewer steps, fewer fields, less effort
Checkout is often weighed down by good intentions: collecting more data, pushing account creation, asking for information “just in case.” The result is the opposite of the goal: more friction, more abandonment.
Stripe recommends a one-page checkout when possible, with only the strictly necessary information. Shopify also notes that consumers expect a fast experience: according to the data cited in their guide, two consumers out of three expect to complete their checkout in four minutes or less.
The most profitable optimizations
Systematic guest checkout.
Short forms: remove unnecessary fields.
Autocomplete for addresses and already known data.
Clear error messages: no confusing or punitive validation.
Visible progress if the journey has multiple steps.
The general principle is simple: each piece of information requested must have a real justification. If it does not directly help finalize the order or secure delivery, it deserves to be questioned.
Payment methods play a bigger role than people think
Payment is not a mere formality. It is also a signal of comfort and trust. Stripe notes that a lack of options can exclude entire segments of shoppers depending on their preferences and regional habits.
Shopify adds that limited payment options are among the direct causes of abandonment, and recommends offering multiple methods, including wallets and buy now, pay later when it makes sense.
What a good checkout should offer
Classic cards: credit and debit.
Wallets: Apple Pay, Google Pay, PayPal, Shop Pay depending on the market.
BNPL when the cart, category, or price sensitivity justify it.
Clear payment error handling to avoid a hard exit after a decline.
Shopify also says that Shop Pay can convert up to 50 % better than a standard guest checkout. Even without using exactly this stack, the logic remains strong: the less the customer has to re-enter information, the higher the likelihood of completion.
Mobile accounts for most checkout friction
Mobile checkout is not a “small desktop.” It is a much more fragile context: smaller screen, distractions, awkward input, variable network conditions, greater cognitive fatigue.
Stripe emphasizes the importance of a mobile-first experience: simple interface, minimal input, speed, smooth payment. Shopify, for its part, more broadly notes that mobile now dominates a large share of e-commerce journeys, which increases the cost of a poorly designed checkout on smartphones.
The points to fix as a priority on mobile
Appropriate keyboards and fields: phone, postal code, email, card.
Buttons that are sufficiently visible and touch-friendly.
Readable order summary without tedious back-and-forth.
Express payments to reduce input.
Short loading times and technical stability.
This logic directly aligns with the strategy described in the mobile-first article: poor mobile performance doesn’t just reduce comfort. It hurts conversion at the most sensitive point in the funnel.
Trust is built on very concrete details
Many brands think they can “reassure” customers by stacking security logos. It’s useful, but it’s not enough. Shopify makes a very good point in its article: sometimes trust is also built through greater clarity at the exact point where a decision has to be made.
Typical example: if the customer chooses a shipping method and doesn’t know when the package will arrive, the experience remains vague. That ambiguity is enough to create doubt. Shopify therefore recommends enriching the information right at the moment of choice, for example with a more concrete delivery estimate.
The trust elements that really matter
Precise delivery times, not just “standard.”
Clear return policy and easy to find.
Visible security signals in the right place.
Contact details or support accessible in case of a problem.
Clear order summary before confirmation.
Two often overlooked topics also need to be addressed: returns and technical reliability. Shopify points out that an unsatisfactory return policy directly contributes to abandonment, and that technical errors are also among the main causes. A checkout that looks fine but occasionally glitches, fails to refresh the cart properly, breaks on some browsers, or displays ambiguous error messages destroys trust faster than a high price. That’s why a good checkout should be tested regularly on multiple devices, multiple browsers, and multiple payment scenarios.
A reassuring checkout isn’t one that speaks louder. It’s one that leaves fewer gray areas.
Cart reminders are powerful, but they should not mask a faulty checkout
Once the checkout has been cleaned up, abandonment flows become a powerful lever. Klaviyo shows that cart abandonment is among the most profitable automations.
In its 2024 benchmark, Klaviyo indicates that cart abandonment flows average:
50.5% open rate
6.25% click rate
3.33% conversion
$3.65 revenue per recipient
For the top 10% of brands, Klaviyo even observes 7.69% conversion and $28.89 revenue per recipient. This shows that a basic sequence can already be profitable, and that optimization can take things much further.
But the email sequence should not become an excuse. If your checkout is leaking because of hidden fees, poor mobile UX, or a lack of payment methods, you will only partially offset a structural problem.
How to build a good recovery sequence
Klaviyo often recommends a simple three-step sequence: a reminder, then possibly an incentive, then a final broader or more contextual message. It all needs to be tested, not copied mechanically.
An effective foundation
First quick reminder: between 2 and 4 hours after abandonment. Goal: simply remind them about the cart.
Second message: around 24 hours later. Goal: address an objection, reassure, and possibly test an incentive.
Third message: around 48 hours later. Goal: create a final useful follow-up, suggest alternatives, or ask for feedback.
Klaviyo also emphasizes the importance of A/B testing: timing, frequency, visuals, subject line, discount or not, personalization, everything must be tested.
The most important point remains this one: not all carts need a discount. Klaviyo warns against the automatic discount mindset, which can train customers to wait for a promotion before buying. This point ties directly to pricing strategy: recovering an order is not always worth it if the margin is destroyed in the process.
How to audit a checkout without getting lost
A good audit does not start with a complete redesign. It starts with precise questions.
1. Where does the progression drop off?
Between cart and checkout? Between checkout and payment? After entering the address? After choosing shipping?
2. What is the mobile vs desktop gap?
A gap that is too large often signals a readability, input, or mobile performance issue.
3. Are the costs understood before the final screen?
If not, you already have a strong hypothesis.
4. What recurring support issues are there?
Questions about returns, delivery, payment, promotions, and delivery times.
5. Which payment methods are missing?
This gap varies by country, device, and average order value.
To conduct this audit properly, you need to connect the checkout to a broader view of the funnel and e-commerce analytics. A checkout is never isolated. It inherits what was promised and understood upstream.
Qstomy: useful when abandonment stems from unanswered questions
Not all abandonments come from a bug or a hidden fee. Some also stem from a doubt that wasn’t addressed in time: “Is this the right variant?”, “Can I return it easily?”, “When will I receive the package?”, “Is it compatible?”.
Qstomy can help reduce this friction by answering in real time the questions that make shoppers hesitate right before purchase, but also by easing part of the post-purchase burden around delivery times, tracking, or service policies.
If you sell on Shopify : see the Shopify integration.
If you want to test the impact : request a demo.
Qstomy does not replace a well-designed checkout. However, it can reduce some abandonments when the real cause is a lack of clarity or reassurance at the last moment.
In short, sources and FAQ
In brief
Reducing cart abandonment starts with a more transparent, simpler, more reassuring checkout that is better adapted to mobile. Abandonment emails and retargeting are useful, but they work much better when the checkout foundation is already solid.
Hidden costs remain the main cause of abandonment.
Guest checkout, express payments, and fewer fields directly improve the flow.
Mobile deserves specific attention: input, speed, readability, wallets.
Trust is built in the details: returns, delivery times, security, visible total.
Abandonment flows are profitable, but should not eternally make up for poor checkout UX.

FAQ
What is the main lever for reducing cart abandonment?
Cost transparency is often the number one lever. If the real fees appear too late, trust and conversion drop immediately.
Is guest checkout mandatory?
Yes, in most cases. Forcing account creation adds unnecessary friction, especially for a first purchase.
Are cart abandonment emails enough?
No. They are very profitable, but they do not fix a checkout that is structurally too complex, too vague, or poorly adapted to mobile.
Should you always offer a discount in follow-ups?
Not necessarily. A systematic discount can erode margin and create promotional expectations. It is better to test and segment.
Which metrics should you track to audit a checkout?
The cart-to-checkout step, the checkout conversion rate, device performance, payment errors, support tickets related to delivery and returns, as well as recovery rates after abandonment.
