Why your website’s checkout is sabotaging sales

You’ve spent thousands on ads, your homepage looks sharp, and people are clicking through to your store. So why are they leaving without buying?

I see this all the time with Australian business owners. They obsess over traffic but ignore the moment of truth: the checkout. If that page clunks, hesitates, or asks for too much info, you can kiss that sale goodbye. Let’s walk through the specific ways your checkout might be sabotaging sales — and how to fix it.

The hidden cost of a clunky checkout

A slow or confusing checkout doesn’t just annoy customers. It actively trains them to abandon their cart and buy from someone else. In Australia, where shoppers are already wary of shipping costs and delivery times, a bad checkout experience is the final push they need to leave.

Think about it this way: getting a customer to your site is hard work. Every abandoned cart is money you paid for in ads but never collected. If your checkout has friction, you’re basically paying people to leave frustrated.

Asking for too much, too soon

One of the biggest mistakes I see on Australian ecommerce sites is a checkout that feels like a job application. You don’t need their phone number, their company name, or their date of birth to sell a pair of socks.

The minimum viable checkout

Ask yourself: what is the absolute minimum information I need to process this order? Usually that’s a name, an email, a shipping address, and payment details. Everything else can wait — or be collected after the sale.

I worked with a Melbourne-based skincare brand last year. They were asking for a landline number and a “delivery instructions” field before customers could even see the total. Once we stripped those out, their conversion rate jumped by nearly 15 percent in two weeks.

Guest checkout isn’t optional

Forcing people to create an account is the fastest way to kill a sale. People want to buy, not sign up for a newsletter or “join your community.” Offer guest checkout as the default, and let account creation be an optional afterthought.

If you’re worried about losing customer data, offer a “save my info for next time” checkbox after the payment goes through. That respects their time and still builds your database.

Hidden costs and surprise fees

Australians are famously sensitive to unexpected charges. We’ve all been burned by a $10 delivery fee that only appears at the final step. When you hide costs, you break trust — and trust is the only thing that makes someone hand over their credit card.

Show the total early

Display the full price, including estimated shipping and GST, as soon as someone adds a product to their cart. If shipping varies by location, show a rough estimate or a “free shipping over $50” banner on every page.

One of my clients in Brisbane was losing 20 percent of their checkouts because they only showed the delivery fee on the final review screen. Moving that estimate to the cart page recovered most of those lost sales.

Be upfront about payment surcharges

If you pass on credit card fees (which is legal in Australia under certain conditions), say so clearly before the customer starts typing their details. Nothing feels more scammy than a 2 percent surcharge appearing after you’ve entered your card number.

Mobile checkout is a nightmare

Over half of Australian online shopping happens on a phone. Yet so many checkouts are clearly designed for a desktop screen, with tiny buttons, overlapping fields, and endless scrolling.

Thumb-friendly design

Make sure every button, input field, and link is large enough to tap without zooming. A good rule of thumb: anything clickable should be at least 48 pixels tall. That’s about the width of your thumb on a standard phone screen.

Also, avoid forcing users to pinch and zoom to read field labels. Use a single-column layout that stacks naturally on mobile. If you have a two-column checkout on desktop, make sure it collapses into one column on a phone.

Autofill and autocomplete

Enable browser autofill for name, address, and card details. It sounds obvious, but I still see sites where the fields have non-standard labels that break autofill. Test this yourself: fill out your own checkout on a phone and see how many fields you have to type manually.

Payment options that don’t match your audience

Australians have strong preferences when it comes to payment methods. If you only offer credit cards and PayPal, you’re locking out a chunk of customers who use Buy Now, Pay Later services like Afterpay or Zip.

Know what your customers use

For most Australian ecommerce stores, the top payment methods are credit/debit cards, PayPal, and Afterpay. But depending on your audience, you might also need Apple Pay, Google Pay, or direct bank transfer (for B2B).

I had a client selling outdoor gear to tradies. They added Afterpay and saw a 25 percent jump in average order value — not because people were broke, but because splitting a $300 tent into four payments felt easier than dropping the whole amount at once.

Don’t clutter the page

You don’t need to show every payment option at once. Show the three most popular ones, then a “more payment options” link for the rest. Too many logos can overwhelm people and slow down the decision.

The redirect problem

Some payment gateways take customers away from your site to complete the transaction. That’s fine for small stores, but it can confuse shoppers and increase abandonment.

Keep them on your domain

If possible, use a payment gateway that lets customers stay on your site (like Stripe Elements or a hosted checkout that matches your branding). When people see a unfamiliar URL, they sometimes think they’ve been redirected to a scam site.

This is especially true for older Australians who are more cautious about online security. A seamless, on-site checkout builds confidence and reduces second-guessing.

A quick anecdote from a local cafe owner

I once helped a small cafe in Sydney that sold coffee beans online. Their checkout had a multi-step form that asked for “shipping address” before letting you choose “pick up in store.” A customer who wanted to pick up their order had to enter a fake address to proceed.

We added a simple toggle at the top: “Deliver” or “Pick up.” That one change cut their checkout time in half and reduced support emails about “how do I select pickup?” by 80 percent. The lesson? Let people self-identify their needs early.

Practical takeaway

Your checkout isn’t just a form — it’s the final handshake with your customer. Every field you add, every extra click, every surprise fee is a reason for them to leave.

Start this week by testing your own checkout on a phone. Fill it out as if you were a first-time buyer. Note every moment of hesitation, every field that feels unnecessary, every time you have to scroll or zoom. Then fix the worst three things. That small investment will pay for itself in recovered sales faster than almost any ad campaign you could run.
