Checkout, and the places people abandon it

A well-documented, specific set of friction points accounts for most cart abandonment — not a vague sense that customers got “distracted.” Each one is checkable on your own store in a few minutes, and each has a specific, known fix. Many online retailers treat abandoned carts as a single undifferentiated problem when it is actually several separate ones.

The common friction points behind cart abandonment, and what addresses each

Friction point	What happens	What addresses it
Unexpected costs revealed late	Shipping, taxes or fees appear only at the final step	Show estimated shipping and the GST-inclusive total as early as possible
Forced account creation	Customer must register before completing purchase	Offer a genuine guest checkout option
Too many steps	Checkout spans several separate pages with repeated navigation	Consolidate to as few steps as the platform sensibly allows
Limited payment methods	The customer’s preferred method (a specific digital wallet, buy-now-pay-later) isn’t available	Offer the payment methods your specific customer base actually uses
Security concerns	No visible trust signals at the point of entering card details	Display recognisable payment logos and a visible secure-checkout indicator
Slow page load at checkout	The checkout page itself is slow, adding friction at the highest-intent moment	Treat checkout page performance as a priority, not an afterthought
No clear return to cart	An error or a changed mind loses the customer’s cart contents entirely	Persist cart contents across sessions, not just within one visit

Why “unexpected costs” is usually the single largest factor

A customer who has mentally committed to a price, then sees it increase at the final step — shipping cost, GST if it wasn’t shown inclusive earlier, a service fee — experiences that increase as a small betrayal of the price they had already accepted, which is a disproportionately strong reason to abandon compared with the same total cost shown honestly from the start. Showing an estimated total, GST-inclusive, as early in the flow as practically possible — even before shipping address is known, using an estimate — measurably reduces this specific friction. This is also, separately, an Australian Consumer Law consideration: section 48 requires a stated single price to be the GST-inclusive total, and revealing it only deep in checkout sits uncomfortably close to that requirement even where it technically complies.

Guest checkout, again

Forced account creation is one of the most consistently cited abandonment causes across ecommerce generally, covered in more depth on customer accounts and portals. If your platform defaults to requiring an account, check whether a genuine guest option can be enabled — it usually can be, and it usually should be.

Why checkout step count matters more than it seems

Each additional step in a checkout flow is another point where a customer can be interrupted — a phone call, a change of mind, a distraction — and not return. Consolidating to the fewest steps your platform sensibly supports, without cramming so much onto one page that it becomes confusing, is a genuine, testable lever most platforms let you adjust through their checkout configuration.

Payment method breadth, and its real trade-off

Adding payment methods — buy-now-pay-later services, digital wallets, bank transfer — captures customers whose preferred method wasn’t otherwise available, but each additional option adds a small amount of checkout complexity and, for some gateways, additional integration and fee considerations covered on payment gateways explained. Add options based on evidence of what your actual customer base wants, rather than adding every available option by default.

How to actually diagnose your own abandonment

Most ecommerce platforms report where in the checkout flow abandonment concentrates — which step, not just an aggregate rate. A rate that concentrates heavily at one specific step (commonly the shipping-cost reveal, or a forced login prompt) points to a fixable, specific problem. A rate spread evenly across all steps is more likely to reflect genuine window-shopping traffic that was never going to convert, and is a different problem — traffic quality, not checkout friction.

Mobile-specific checkout friction, worth checking separately

A checkout that works acceptably on desktop can still fail specifically on mobile — form fields too small to tap accurately, a keyboard that doesn’t match the expected input type (bringing up a full alphabetic keyboard for a numeric card field, for instance), or a layout that requires excessive scrolling to reach the payment button. Given that a substantial share of ecommerce traffic is now mobile, test the checkout flow specifically on a phone rather than assuming a desktop-tested flow transfers cleanly.

Why re-engagement after abandonment is a separate, worthwhile tactic

Beyond fixing the friction points themselves, many platforms support automated follow-up — an email reminding a customer of items left in their cart, sometimes with an incentive — sent a set period after abandonment. This doesn’t address the underlying friction, but it recovers some otherwise-lost sales in parallel with fixing the actual causes, and it’s a relatively low-effort feature to enable once the basic email capture is in place.

Why testing changes one at a time matters

When addressing abandonment, changing several checkout elements simultaneously — adding a new payment method, removing a step, and changing the shipping-cost display all at once — makes it difficult to know afterwards which change actually helped. Where the platform supports it, testing one meaningful change at a time against a clear before-and-after comparison gives a much clearer picture of what’s actually working, rather than a general sense that “abandonment seems better now.”

What to do next

Check your platform’s checkout analytics for where abandonment actually concentrates before assuming a general fix is needed, and test the highest-impact friction points — unexpected costs and forced account creation — first, since they consistently account for the largest share of recoverable abandonment. What a complete build should already account for on this front is set out on ecommerce website design in Australia.
