If you sell online in Melbourne, your hardest work is already done by the time a shopper reaches the checkout. You have won the click, the browse and the add-to-cart. Then the sale quietly disappears. New research puts a number on how often this happens: 72% of Australians have abandoned a cart, rising to 82% of Gen Z. Cart abandonment is not a fringe problem — it is the norm. The PayPal 2026 eCommerce Index, based on 1,012 consumers and 410 business decision-makers, maps the friction driving it, and the fixes are refreshingly ordinary. This is a plain read on where checkouts leak sales, and what to do about each one.
Trust at the checkout is the top cause of cart abandonment
Ask Australians what makes them abandon a purchase and the answer is trust. Security and trust issues at the checkout are the single biggest barrier to buying, cited by 65% of shoppers — ahead of every other friction point. Among people who have walked away from a full cart, 38% did so over security concerns.
The gap here is rarely about your actual security. It is about how safe your checkout looks in the two seconds a shopper decides whether to hand over their card. Visible trust signals close that gap. Recognised payment logos do real work: 35% of Australians say seeing PayPal branding on a product page makes them more likely to buy, and PayPal’s research found it is the single most-trusted payment option at 42%, with 70% trusting it to keep their payment secure. The point is not one brand — it is that familiar, reputable payment marks, plain-English security messaging and a checkout that feels professional all reassure a nervous buyer. If your checkout looks dated or improvised, a solid website design is the cheapest trust upgrade you can make.
Offer the payment method they already reach for
The second-biggest barrier is almost embarrassingly simple: 50% of shoppers are less likely to buy if their preferred payment type isn’t offered. Flip it around and it becomes the number-one thing that makes people buy — 59% are more likely to complete a purchase when their preferred method is available. Among abandoners, 31% left specifically because the option they wanted wasn’t there.
Australians don’t all pay the same way. Asked for their preferred online method, 30% name PayPal, 23% a credit card, 18% a debit card and 12% Apple Pay. Build your checkout around one narrow rail and you are turning away a real slice of ready buyers at the last step. Covering the common spread is a small piece of plumbing that removes a needless reason to leave.
Cut the long, confusing checkout — especially on mobile
A long or confusing checkout is the third-largest barrier, putting off 42% of shoppers, while easy navigation is a positive driver for 49%. Every extra field, unexpected step and unexplained charge is another chance to lose the sale.
This matters most on a phone. Smartphone-only shopping has more than tripled to 24% of Australians, and the phone is now the single most-preferred way to shop, named by 44% ahead of laptop (30%) and desktop (16%). A checkout that works on a wide desktop screen but forces pinch-zooming, tiny tap targets or a fiddly multi-page form on mobile is quietly costing you a growing share of customers. Checkout optimisation here is unglamorous but high-return: fewer steps, a visible progress indicator, autofill support and large, thumb-friendly buttons. A mobile-first website build treats the phone checkout as the main event, not an afterthought.
Let people buy without making an account
Forcing shoppers to create an account before they can pay is one of the most self-inflicted forms of cart abandonment there is. It’s a barrier for 40% of Australians, and among people who abandoned a full basket, 35% blame a forced sign-up. Nobody adds items to a cart because they want a new password to remember.
The fix is guest checkout: let people buy with just an email and a delivery address, and offer the account afterwards — “save these details for next time?” — once the sale is banked. You still capture the customer; you just stop treating registration as a toll gate in front of your own revenue.
Shipping surprises (and broken promo codes) break the deal
Two of the biggest deal-breakers happen after the shopper has already decided to buy. Shipping is the first. Expensive shipping deters 83% of Australians and long shipping times deter 47%, while free shipping motivates 85% and delivery within the expected window matters to 56%. A postage cost that only appears on the final screen reads as a nasty surprise, even when it’s fair. Show shipping costs early, state a free-shipping threshold up front, and set honest delivery expectations.
The second is the sleeper. The single most common stated reason Australians abandon a cart is a promo or gift code that didn’t work — 40% of abandoners. A broken discount field turns an eager buyer into a frustrated one at the worst possible moment. And 26% deliberately abandon carts hoping to be sent an offer, so a reliable, working code path is part of your conversion engine, not a nice-to-have. Test your codes the way a customer would, and do it regularly.
The cheap wins that lift your conversion rate
Not every fix is about removing friction — some are about adding reassurance. Two low-cost signals stand out. Visible product reviews and star ratings make 41% of shoppers more likely to buy, and visible payment branding lifts intent for 35%. Neither needs a redesign; both are conversion rate optimisation in its most affordable form.
Reviews do double duty, because the same content that reassures a hesitant buyer also helps your pages get found — surfacing genuine reviews and structured product information supports both trust and search visibility. Turning on ratings, prompting happy customers for reviews and displaying trusted payment marks are the kind of afternoon jobs that keep paying back for months.
Turn checkout friction into conversions
None of this requires rebuilding your store. The barriers behind most cart abandonment are ordinary and fixable: make the checkout look as safe as it is, offer the payment methods people already reach for, shorten the flow and get it right on mobile, allow guest checkout, and be honest about shipping and discounts early. Each one removes a reason to leave, and together they lift your conversion without a cent spent on more traffic.
