Cart Abandonment Is Costing You Revenue — Here's How to Fix It
Someone adds a product to their cart. Then they leave.
That is not a traffic problem. It is a checkout problem.
Shoppers bail not because they changed their mind, but because something in the process stopped them — a surprise shipping fee on the final screen, five pages of form fields, no Apple Pay option, or a layout that does not feel trustworthy enough to hand over card details.
Ecommerce checkout optimisation is about finding those moments and fixing them — not redesigning for the sake of it.
Show delivery costs earlier in the flow
Enable guest checkout without forcing account creation
Tighten up error messaging — be specific about what went wrong
Add payment options shoppers actually use (Apple Pay, Google Pay, BNPL)
None of that requires a full rebuild. It just requires looking at the data properly.
A common mistake: treating cart abandonment as a marketing problem and throwing retargeting spend at it, when the checkout itself is what is broken. Recover the flow first. Then scale the traffic.

The Real Reasons Shoppers Abandon Their Carts
Most ecommerce teams assume cart abandonment is about price. Shoppers found it cheaper elsewhere, changed their mind, were never really going to buy. Sometimes that is true. Usually it is not.
Session recordings and exit survey data tell a more fixable story. The most common abandonment triggers are process-related, not price-related. That means they are within your control.
Unexpected delivery costs
Appearing on the final checkout screen after the shopper has invested time filling in their details. Showing estimated delivery costs on the product page or cart significantly reduces this.
Forced account creation
Requiring registration before purchase is one of the single highest-friction checkout steps. Guest checkout is not optional for most modern stores — it is expected.
Complicated or lengthy forms
Asking for unnecessary fields, not auto-filling known data, not using address lookup APIs. Each extra field reduces completion rate.
Payment option gaps
Not offering the payment methods your specific audience uses. This varies significantly by country, age group, and product type.
Trust and security concerns
A checkout that does not visually signal security — SSL badges, recognisable payment icons, clear return policies — loses customers who are otherwise ready to buy.
Designing a Checkout Flow That Minimises Drop-Off
Checkout flow design is not about aesthetics. It is about removing every unnecessary decision, click, and moment of uncertainty between "add to cart" and "order confirmed".
The Case for Fewer Steps
Every additional step in a checkout flow is an opportunity to lose the sale. That does not mean collapsing everything into one page — one-page checkouts can feel overwhelming for complex orders. But every step should earn its place. If a field is not needed to process the order, remove it.
Checkout Flow Optimisation Priorities
- Enable guest checkout as the primary path — account creation optional, never mandatory
- Use address lookup or auto-fill APIs to reduce manual entry
- Show order summary persistently so shoppers can confirm without navigating back
- Display delivery cost and estimated date as early as possible
- Make error messages specific — "Invalid postcode" not "Form error"
- Ensure mobile layout is tested properly — most abandonment happens on mobile
- Keep the confirmation page clear with next steps and order details
Mobile Checkout: The Highest-Stakes Optimisation
Mobile cart abandonment is consistently higher than desktop, and the gap is usually attributable to checkout experience, not price. Small text, tiny tap targets, forms that require constant zooming, and payment flows that do not integrate with native mobile wallets all drive unnecessary drop-off.
Test on real devices, not just resized browser windows
Browser resizing does not replicate how forms behave with mobile keyboards, how tap targets feel, or how native payment sheets appear. Testing on actual iOS and Android devices reveals issues that desktop-simulated mobile testing misses entirely.
Payment Options, Trust Badges, and Security Signals at Checkout
Two things happen at checkout that do not happen anywhere else on your site: shoppers hand over financial information, and they make a final commitment to buy. Both require trust signals that are specific to that context.
Which Payment Methods Actually Matter
Offering the right payment methods varies by market, audience, and product type. Apple Pay and Google Pay are increasingly expected on mobile. Buy Now Pay Later options (Klarna, Clearpay) perform well for higher-ticket items and younger demographics. PayPal remains significant for older demographics who prefer not to enter card details directly.
High-priority payment options
- +Apple Pay / Google Pay
- +Credit and debit card (Visa, Mastercard, Amex)
- +PayPal
- +Buy Now Pay Later (Klarna, Clearpay)
Trust signals that reduce friction
- +SSL certificate and HTTPS indicator
- +Recognised payment provider logos
- +Clear returns and refund policy link
- +Security badge near payment fields
Running structured tests on payment options and trust signal placement is one of the clearest use cases for ecommerce A/B testing — you get clean, measurable results directly tied to checkout conversion rate.
Recovering Abandoned Checkouts With Email and Retargeting
Even after you optimise your checkout flow, some shoppers will still leave before completing a purchase. Some were genuinely distracted. Some needed to check something. Some will come back on their own. Recovery sequences help you capture the ones who need a nudge.
Abandoned Cart Email Sequences
A well-structured abandoned cart email sequence typically includes three touchpoints: a reminder within one hour of abandonment (high intent, high urgency), a follow-up at 24 hours that addresses common objections, and a final message at 72 hours — sometimes with a time-limited incentive if your margins allow it.
Timing is more important than discounting
Abandoned cart recovery does not require a discount to work. The first email — sent quickly after abandonment — typically recovers a meaningful share of abandoned orders on its own, because the shopper was often just distracted, not price-sensitive. Discounting trains customers to abandon on purpose.
Paid Retargeting for Checkout Abandoners
Checkout abandoners are a high-value remarketing audience — they have already expressed strong intent. Paid retargeting through Meta and Google Display can complement email sequences, particularly for shoppers who are not email subscribers or who unsubscribed.
One important caveat: recovery sequences should be optimised after the checkout flow itself is improved. Spending on retargeting to drive people back to a broken checkout is a waste of budget. Fix the leak first, then recover the lost sessions.
Your Checkout Can Be Your Greatest Conversion Lever
Most ecommerce brands invest heavily in top-of-funnel marketing — acquisition campaigns, SEO, content — and comparatively little in the single page that determines whether all of that spend results in a purchase.
Checkout optimisation compounds. Every improvement benefits the full volume of traffic you send to the store — not just new visitors from a new campaign. A 1% improvement in checkout conversion rate on a site doing £1m a month in revenue is a meaningful number. And it applies to every future pound of acquisition spend you make.

Frequently Asked Questions
What is the average cart abandonment rate for ecommerce?
Average cart abandonment rates typically sit between 65–75% across most ecommerce sectors. Mobile abandonment tends to be higher. The benchmark matters less than your own baseline — track it and focus on moving it down consistently.
What causes cart abandonment at checkout?
The most common causes are unexpected delivery costs appearing late in the flow, forced account creation, too many form fields, limited payment options, trust concerns, and slow page load times on mobile. Session recordings and exit surveys tell you which applies to your specific store.
How do I reduce checkout abandonment?
Start with an audit of your funnel data to identify exactly where people drop off. Then fix the highest-impact issues first: show delivery costs earlier, enable guest checkout, add Apple Pay and Google Pay, tighten error messaging, and ensure the checkout works well on mobile.
Should I use one-page or multi-step checkout?
There is no universal answer. One-page checkout reduces clicks but can feel overwhelming. Multi-step checkout feels more guided but adds friction. The right answer depends on your audience, device mix, and product complexity — test both with your actual traffic.
