The single most effective approach to checkout optimisation combines four moves: strip the flow down to essentials, show the total price early, support the payment methods your customers already prefer, and measure every step so you fix the step that’s actually leaking revenue. Average cart abandonment sits at around 70.22%, and most of that is fixable. Below you’ll find the priority tactics, the GA4 events to track, and a quick-win checklist you can start today.

Core checkout optimisation strategies that move the needle
Checkout abandonment isn’t one problem, it’s a stack of small frictions that compound. Baymard Institute’s benchmark found that surprise costs account for 48% of fixable abandonment, forced account creation for 24%, and an overly long or complicated process for 17 to 18%. Tackle these in order of impact, not in order of what’s easiest to build.
- Cut form fields to the essentials. Baymard’s research shows many checkouts ask for almost twice as many form elements as ideally necessary; every extra field is a chance for someone to stop and reconsider.
- Enable guest checkout by default. Forcing an account before purchase is one of the top three abandonment triggers; let people buy first and offer account creation as a one-click option after the order confirms.
- Offer social or federated sign-in. For customers who do want an account, a Google or Apple sign-in removes the password-creation step entirely.
- Show the full price before the payment page. Shipping, taxes and fees should appear on the cart page or early in checkout, not as a surprise at the final click.
- Add a visible progress indicator. A simple three-step bar (details, shipping, payment) tells people how much is left and reduces the sense that the process is open-ended.
- Strip the layout of distractions. Remove navigation menus, upsell banners and unrelated links from the checkout page itself; every exit point is a potential abandonment.
- Offer multiple payment methods matched to market preference. Cards alone no longer cover how people want to pay; wallets and buy-now-pay-later options now account for a meaningful share of completed purchases.
- Allow saved payment details through tokenised, third-party wallets rather than asking shoppers to store raw card numbers directly on your site, since trust concerns around card storage are a real deterrent.
- Make support reachable during checkout, whether that’s live chat or a click-to-call option, so a shopper with a question about sizing or delivery doesn’t have to open a new tab and lose their place.
Each of these addresses a specific, named cause of drop-off rather than a generic “improve the UX” instinct. The field-count reduction and guest checkout changes are typically the fastest to ship and the first ones worth testing, since they map directly to the two largest fixable abandonment causes Baymard identifies.
Payments mix and trust signals that reduce abandonment
Which payment methods you offer, and how visibly you reassure people before they hand over card details, has a direct effect on completion rates. This matters more in markets where digital wallets and buy-now-pay-later services have become the default rather than the alternative.
A large share of Australian shoppers use one-click digital wallets for their online purchases, and buy-now-pay-later adoption sits around a substantial portion, according to A substantial portion. PayPal in particular carries outsized influence: Australian shoppers are reportedly far more likely to complete a purchase on sites that accept it. That’s a strong argument for treating wallet buttons as primary checkout real estate, not a secondary option buried below the card form.
- Prioritise Apple Pay, Google Pay and PayPal above manual card entry, since these options remove typing entirely and carry built-in trust.
- Offer buy-now-pay-later where your margins and return rates support it. It tends to help conversion on higher-ticket items but can hurt profitability on low-margin goods if used without discipline.
- Avoid pressuring shoppers to save raw card details on your own site. Tokenised wallet buttons give the same one-click convenience without asking for that trust upfront.
- Display recognisable payment brand logos, an SSL padlock indicator, and a clear link to your refund and returns policy near the payment step.
Australian consumer research backs the trust angle specifically: around a substantial portion of Australians say doubts about payment security erode their confidence in a retailer, according to a summary of Checkout.com research. That means a padlock icon and a returns link aren’t decorative, they’re doing real conversion work for a shopper who’s hesitating at the final step.
Mobile-first checkout improvements that close the conversion gap
Mobile traffic routinely outpaces mobile conversion, and Baymard’s data shows mobile abandonment rates are higher than desktop, often significantly so, a gap that’s almost always a performance and layout problem rather than a demand problem.
- Compress images and defer non-critical scripts so the checkout page loads fast on a mobile connection, not just on your office Wi-Fi.
- Use single-column forms with large tap targets, since thumbs are far less precise than a mouse cursor.
- Turn on autofill and address lookup so customers tap a suggestion instead of typing a full street address on a small keyboard.
- Put wallet buttons (Apple Pay, Google Pay) above the fold on mobile checkout, since these replace multi-field forms with a single tap.
- Simplify shipping choices on mobile specifically. A dropdown with three clear options beats a dense comparison table that requires pinch-zooming.
Stripe’s guidance on mobile commerce points to the same priorities: wallet buttons, tokenisation, fast load times and prebuilt payment interfaces that reduce the engineering lift needed to support multiple payment methods at once.
Pro Tip: Track mobile checkout completion rate separately from desktop in your analytics, not blended into a single conversion number, or you’ll never see which device is actually losing you orders.
Measuring checkout friction with GA4 and funnel data
Guessing which step is losing customers wastes engineering time on the wrong fix. The fastest way to find the real leak is to instrument the checkout journey properly and read the funnel by segment, not by site-wide average.
- Implement the four GA4 checkout events:
begin_checkout,add_shipping_info,add_payment_infoandpurchase. Google’s documentation on the checkout journey report describes these as the standard events needed to build a closed funnel. - Build a closed funnel report from those four events and look for the single step with the steepest drop, rather than trying to fix everything at once.
- Segment that funnel by device, payment method and traffic source, since a 40% drop-off on mobile card entry tells you something completely different to a 40% drop-off on desktop PayPal.
- Layer in session replay and error logs on the leakiest step to see whether the problem is a confusing form, a broken validation message or a payment gateway timing out.
- Set experiment KPIs before you test anything: checkout completion rate, revenue per session, payment decline rate and time-to-complete, so you know in advance what a “win” looks like.
This sequence matters because it stops teams from redesigning the whole checkout when the real problem is one broken field on one payment method on one device. GA4’s funnel exploration template is built specifically to isolate that kind of single-step leak rather than present a flat conversion percentage that hides where people actually give up.
A/B testing and iterative optimisation for checkout
Checkout changes are high-stakes: a badly tested change can quietly cost real revenue before anyone notices. A disciplined test process protects against that.
- Write a specific hypothesis tied to one metric, such as “removing the phone number field will raise checkout completion rate,” and calculate the sample size needed to detect a meaningful effect before launching.
- Prioritise tests that attack the biggest known causes first: surprise costs, forced accounts and field count, since these are the abandonment drivers with the clearest evidence behind them.
- Test one variable at a time where possible: field count, button copy, the order payment options appear in, the progress indicator design, or how shipping cost is messaged.
- Pair quantitative results with qualitative checks. A five-person usability test or a handful of session replays can explain why a test won or lost before you roll it out to 100% of traffic.
Pro Tip: Run a small usability session alongside every major checkout A/B test. A statistically significant lift with no explanation is harder to trust, and harder to build on, than one you can watch happen.
Quick wins checklist for this week
Some fixes don’t need a full test cycle to justify shipping them, because they directly reverse a documented abandonment cause.
- Show the full price, including shipping and taxes, before the payment page.
- Turn on guest checkout and add at least one digital wallet button.
- Remove any form field that isn’t strictly needed to fulfil the order.
- Turn on address autofill to cut typing on both mobile and desktop.
- Add a visible SSL indicator, payment brand logos and a link to your returns policy.
- Instrument the four GA4 checkout events and check which step has the steepest drop-off this week.
| Fix | Addresses | Effort |
|---|---|---|
| Show total price early | Surprise costs (48% of fixable abandonment) | Low |
| Enable guest checkout | Forced account creation (24%) | Low |
| Reduce form fields | Process too long or complicated (17 to 18%) | Medium |
| Add wallet buttons | Payment preference mismatch | Medium |
| Instrument GA4 events | Unknown leak location | Medium |
Figures in the fixable-abandonment column come from Baymard Institute’s checkout usability benchmark.
How we approach checkout optimisation for clients
We treat checkout work as part of a single growth loop rather than an isolated redesign project. That means conversion optimisation sits alongside creative production and paid media under one team, so a change tested on the checkout page can inform the ad creative driving traffic to it, and vice versa.
A typical engagement starts with an audit of the existing funnel against known abandonment causes, builds a prioritised hypothesis backlog, then moves through structured testing before scaling the winners across the full customer base. That sequence mirrors the testing framework above: find the leak, form a hypothesis, test it properly, then roll it out.
Accessibility considerations in checkout design
A checkout page that fails screen reader users or keyboard-only shoppers isn’t just excluding people, it’s actively abandoning completed sales. Form fields need properly associated labels, not just placeholder text that disappears once someone starts typing, since placeholder-only labels confuse screen readers and vanish from view exactly when a user needs them most.
Every interactive element, from payment method selectors to the final submit button, needs to be reachable and operable using the keyboard alone, in a logical tab order that follows the visual flow of the page. Error messages should be announced to assistive technology the moment they appear, not just displayed as a colour change that a screen reader can’t detect.
Sufficient colour contrast matters for form borders and error states as much as for body text, and focus indicators need to stay visible rather than being stripped out for a cleaner look. None of this requires a separate accessible checkout, it requires building the one checkout correctly from the start.
Testing with an actual screen reader, such as the free NVDA on Windows or VoiceOver built into macOS and iOS, catches problems that automated accessibility scanners routinely miss, particularly around dynamic content like inline validation messages or an updating order summary.
Personalisation and dynamic content in checkout
Smart use of saved data can shorten checkout without making it feel invasive. A returning customer who sees their last delivery address pre-filled, or their preferred payment method already selected, has fewer decisions to make and fewer fields to fill.
Dynamic shipping options are one of the more useful applications: showing express delivery only when it’s genuinely available for that postcode avoids the frustration of selecting an option that later turns out to be unavailable. Similarly, surfacing a relevant add-on, such as a protective case for a phone just added to cart, works better in the cart step than it does once someone has already committed to paying.
The line to watch is relevance versus clutter. A checkout page crowded with upsells and recommendations undoes the simplicity gains from reducing form fields elsewhere, so personalisation here should remove friction, such as pre-filling known details, rather than add decisions. Saved preferences work best when they’re a convenience the customer opted into, not a surprise that raises privacy questions at the exact moment they’re entering payment details.
How shipping and return policies affect checkout completion
Shipping cost is a major named driver of cart abandonment; hidden fees also contribute significantly, according to the Payments Consulting ecommerce payments experience report. That lines up with Baymard’s finding that surprise costs are the leading fixable cause of checkout abandonment generally.
The fix isn’t necessarily free shipping for every order, which isn’t viable for every margin structure. It’s showing the real shipping cost as early as the cart page, before the customer has invested time filling in their details, so the final total at payment matches what they already expected.
Return policy visibility plays a similar but less obvious role: a clear, easy-to-find returns link reduces the perceived risk of a purchase, particularly for clothing, footwear and anything where fit or appearance matters. Burying the returns policy in a footer link three clicks away removes a trust signal that costs nothing to surface prominently on the product and checkout pages.
Multi-currency and internationalisation for global checkout
Selling across borders adds a layer of checkout complexity that domestic-only retailers don’t face. Displaying prices in the shopper’s local currency, rather than forcing a mental conversion from a foreign currency symbol, removes one more point of hesitation at the moment of payment.
Address formats vary significantly by country, and a checkout form built around one country’s postal structure will frustrate or outright block customers elsewhere. Supporting flexible address fields, or detecting the shipping country early and adjusting the form accordingly, avoids forcing an awkward workaround.
Payment method expectations also shift by market. A wallet or BNPL option that drives conversion in one country may be irrelevant or even unfamiliar in another, so a one-size-fits-all payment menu underperforms a checkout that adapts its options to the shopper’s detected region. Tax and duty transparency matters here too: an international order that arrives with an unexpected customs charge creates the same trust damage as a domestic surprise shipping fee, just discovered later and harder to resolve.
A closing thought on priorities
If you only do three things this quarter, cut your form fields, show your real price early, and instrument the GA4 events so you can see which step is actually bleeding customers. Everything else in this guide compounds on top of that foundation, but guessing at fixes without funnel data wastes the engineering time you could spend testing something that matters.
Stores running under 100k monthly traffic need to look for big moves for drastic changes. Don’t settle for 5% improvement and call it a day. You need sweeping changes to move the needle by 20-40% at a time to make the change worthwhile — Harry
Getting hands-on help with checkout optimisation
Reading a checklist is one thing, prioritising it against your engineering backlog and your actual funnel data is another. That’s the gap our conversion optimisation work is built to close, sitting alongside creative production and paid media so a checkout fix and a landing page test inform each other rather than running in isolation.
If your team needs support turning funnel data into a tested, shipped set of checkout changes, our conversion optimisation and campaign services cover the audit, the hypothesis backlog and the testing cycle described above.
- We build analytics instrumentation and funnel analysis before recommending any change.
- We run structured A/B tests against the highest-impact abandonment causes first.
- We connect checkout fixes to the ad creative and campaigns driving traffic so the two efforts support each other rather than working against each other.

FAQ
How can I improve my checkout process?
Start by cutting unnecessary form fields, enabling guest checkout, and showing your total price including shipping before the payment step, since these address the three leading fixable causes of abandonment identified by Baymard Institute. Then instrument GA4’s checkout events to confirm which specific step is losing the most customers before investing in a bigger redesign.
What does checkout mean in ecommerce?
Checkout is the sequence of steps a shopper completes after adding items to their cart, typically covering shipping details, payment information and order confirmation. It’s the final and most fragile part of the buying journey, where small friction points have an outsized effect on whether a sale completes.
How can I make WooCommerce checkout more efficient?
The same principles apply to WooCommerce as to any platform: reduce the number of required fields, enable guest checkout, and add wallet payment buttons like Apple Pay or Google Pay through your payment gateway plugin. Pair that with GA4 event tracking to confirm which step of your specific WooCommerce setup is causing the most drop-off before making further changes.
What is ecommerce optimisation?
Ecommerce optimisation is the ongoing process of improving an online store’s ability to convert visitors into paying customers, covering everything from page speed and product pages through to the checkout flow itself. It relies on funnel data and testing rather than one-off redesigns, since even small, evidence-based changes to the checkout can meaningfully affect how many visitors complete a purchase.
Do digital wallets really reduce cart abandonment?
Digital wallets reduce the typing and decision-making required at checkout, which directly addresses the “process too long or complicated” abandonment cause. In markets with high wallet adoption, such as the significant portion of Australian shoppers who used one-click wallets for their most recent purchase according to PYMNTS, offering them prominently tends to lift completion rates for mobile traffic in particular.
