Your checkout page is the single highest-leverage page on your entire store. And most Shopify brands are quietly leaving 10-20% of their revenue on the table there every single month.
What’s in This Article
Here’s the uncomfortable maths. The average Shopify cart abandonment rate sits at 70.2% in 2026. On mobile — where most Aussie shoppers now buy — it’s worse at 76.8%. For every 10 people who add to cart, 7 walk away. If you spend $10,000 a month on Meta ads driving traffic into that funnel, $7,000 of it is evaporating at the final step.
Most brands respond to this by throwing more ad budget at the top of the funnel. That’s backwards. A 2% lift in checkout conversion is worth more than a 20% drop in your CPMs — and it compounds every single day, on every single traffic source, for free. This article walks you through the 9 highest-leverage checkout fixes we put into place with every eCommerce Circle member. Work through them in order, and you’ll usually see a 10-15% lift in completed orders within the first fortnight.
Why Checkout Is the Most Under-Invested Page on Your Store
Founders obsess over the homepage. They A/B test hero images, rewrite product descriptions, argue about brand colours. Meanwhile, the checkout — the page where the actual money changes hands — gets whatever Shopify ships out of the box and a “Thanks for your order” page nobody has touched in two years.
You can understand why. Shopify Checkout converts up to 36% better than other ecommerce platforms straight out of the box, which creates a dangerous sense of complacency. “It’s already the best-converting checkout in the world, why touch it?” Because “better than WooCommerce” is not the same as “optimised for your specific customer, on their specific device, with their preferred payment method.” Those gaps are where the money lives.
Think of your checkout as the last 100 metres of a marathon. The customer has already done the hard work. They’ve watched your ad, clicked through, read your product page, weighed their options, added to cart. If they fall over in the last 100 metres, it’s almost always because of a pebble in their shoe — something small, fixable, and usually invisible until you go looking for it.
Fix 1: Kill the Shipping Shock Before It Happens
The single biggest killer of Shopify checkouts is unexpected extra costs at checkout. Baymard Institute research, which is the gold standard for checkout data, shows 47% of shoppers who abandon do so because shipping, taxes or fees blindsided them. Forty-seven percent. No other reason comes close.
Here’s the fix — and it’s not “offer free shipping on everything”. That nukes your margin. The fix is eliminate the surprise. Your customer should know exactly what they’re going to pay before they ever hit the checkout button.
- Add a free shipping threshold bar on every product and cart page. “You’re $17 away from free shipping” turns a cost into a game. Shopify apps like Hextom or Pumper do this in ten minutes.
- Show the shipping cost in the cart, not just the checkout. Use Shopify’s native shipping calculator or a cart drawer that surfaces rates by postcode.
- Put your shipping policy in the add-to-cart area. “Ships from Melbourne. Standard delivery $9.95 or free over $100.” One line. Zero surprises.
- Strip out the add-on fees. Handling fees, insurance fees, “processing” fees — they feel clever but they cost you 3-5% of conversions. Bake them into product pricing instead.
The goal: by the time a shopper lands on your checkout page, the total they see is exactly the number they were already expecting. No math required, no unpleasant arithmetic.
Fix 2: Turn On Every Express Checkout You Can
If you take nothing else from this article, take this: enable Shop Pay, Apple Pay, Google Pay, and PayPal One Touch on every product page, cart page, and checkout. Then measure what happens.
The numbers on express checkout are ridiculous. A Big Three management consulting study found Shop Pay lifts conversion by up to 50% relative to guest checkout, and outperforms other accelerated checkouts by at least 10%. Shopify’s own data shows Shop Pay delivers a 9% conversion lift across all checkouts and an 18% lift for returning customers. On the order-value side, Shop Pay orders carry a 15% higher AOV than standard checkout orders.
Express checkout isn’t a “nice to have.” It’s the equivalent of a 9-18% discount code that costs you nothing to give. If you’re not running it yet, open your Shopify admin right now, go to Settings → Payments, and turn on every accelerated checkout option Shopify offers. It takes five minutes. You don’t need a developer. You don’t need a strategy meeting. Just switch them on.
One watch-out for Aussie brands: make sure Shop Pay is enabled for international customers if you ship overseas. By default it’s turned on for domestic, but the international toggle is sometimes missed, and it’s where a big chunk of your higher-AOV returning customers live.
Fix 3: Default to Guest Checkout (Stop Forcing Accounts)
Twenty-five percent of shoppers abandon the moment you force them to create an account. That’s a quarter of your cart gone, for nothing. Enabling guest checkout reduces abandonment by 14-18% compared to forced account creation — a bigger lift than almost any CRO test you’ll ever run.
In Shopify, head to Settings → Checkout → Customer accounts and set it to “Accounts are optional.” Not required, not disabled — optional. You still capture the email, you still build your list, you still enable the post-purchase account creation prompt. You just don’t make it the gate between the customer’s credit card and your bank account.
If you want repeat purchases — which you should, because that’s where real profit lives — rely on Shop Pay to do the “remember me” job for you. Shop Pay stores the customer’s details and pre-fills them on their next visit, 4x faster than guest checkout. It’s a better retention mechanism than account creation ever was, and it’s frictionless.
Fix 4: Stack the Australian BNPL Options
Australia is one of the most BNPL-saturated markets on earth. The Australian BNPL market is forecast to hit $18.34 billion in 2026, growing 17.5% year-on-year. If you’re running a consumer brand at any price point above $50 and you don’t have Afterpay, Zip, and ideally PayPal Pay in 4 at checkout, you’re leaking customers to competitors who do.
Here’s the Aussie-specific checkout payment stack we recommend to every eCommerce Circle member:
- Shop Pay — non-negotiable, biggest conversion lever you have.
- Apple Pay + Google Pay — mobile is 70%+ of your traffic. These are one-tap checkouts on iOS and Android.
- Afterpay — still the most recognised BNPL brand with Australian shoppers, especially in fashion, beauty and home.
- Zip — captures the slightly older, higher-AOV segment. Good complement to Afterpay.
- PayPal (with Pay in 4) — picks up the BNPL customers who trust PayPal more than standalone BNPL brands.
- Credit/debit card — still the baseline, but should rarely be the default the customer has to reach for.
Just as important: show these options before checkout. Add “4 payments of $X with Afterpay” messaging directly on the product page and in the cart drawer. Apps like Zip On-Site Messaging and Afterpay’s native product page widget handle this natively. The mental shift from “$160” to “4 x $40” is enormous — it pulls customers out of price shock and into purchase mode.
Fix 5: Put Trust Signals Where the Anxiety Lives
Nineteen percent of abandoners say they didn’t trust the site with their credit card info. That’s a trust problem, not a technology problem — and it’s solved with signals, not platforms.
Here’s where to place trust signals on your checkout — in order of priority:
- Directly under the credit card field: “Secure checkout • 256-bit SSL • Your card details are never stored.” One line. Small text. Visible without scrolling.
- Next to the order summary: A small review snippet — “4.9 stars from 3,400+ reviews on Judge.me.” Customers need to see other people have bought this and lived to tell the tale.
- In the shipping step: “30-day returns. No questions asked. Free returns within Australia.” Refund anxiety is checkout anxiety.
- On the order button itself: Don’t just say “Pay now.” Say “Place Order — Free Returns” or “Complete Order — Secure Checkout”. The button is the last thing they read before they click.
Avoid the cluttered “trust badge graveyard” — those rows of McAfee, Norton, VeriSign logos. Baymard’s eye-tracking research shows they actively hurt trust on mobile because they look spammy and date-stamp your site. Replace them with real, specific, human signals: review stars, shipping guarantees, and your returns policy.
Fix 6: Reduce Form Friction to Almost Nothing
18% of shoppers abandon because the checkout process was too complicated. “Complicated” usually means “typing on a phone.” Every field you can remove or auto-fill adds 1-2% to your conversion rate.
The form friction audit checklist:
- Enable Google address autocomplete. Shopify has this built in for most regions — turn it on. One tap fills street, suburb, state and postcode.
- Use proper input types. Phone fields should trigger the number keyboard on mobile. Email fields should trigger the email keyboard. If a customer has to switch keyboard modes, you’ve already lost 5% of them.
- Ditch optional fields. “Company name”? Cut it. “Phone number” as required? Only if you actually need it for delivery. Every field you kill earns you conversion.
- Real-time inline validation. Show the error the moment they tab out of the field, not after they hit “Pay now” and the whole page reloads. Shopify handles this natively — but your custom apps sometimes don’t.
- Use a single “Full name” field, not separate First/Last. One less tap, one less decision.
Run the test yourself right now: open your store on your phone, add a product to cart, and try to checkout with your thumb only. Time it. If it takes more than 45 seconds end-to-end, you have work to do.
Fix 7: Design for Mobile First, Desktop Second
Mobile abandonment is 76.8%. Mobile conversion sits at 1.0% versus 2.3% on desktop. In other words, your mobile customers convert at less than half the rate of your desktop customers — but they outnumber desktop users by 3 to 1. The mobile checkout is where the biggest lift lives, and where most brands invest the least.
Mobile checkout rules we enforce for every eCommerce Circle member:
- Thumb-friendly buttons: Primary CTAs at least 44x44px, positioned in the bottom third of the screen where thumbs naturally sit.
- Sticky “Place Order” button on the final checkout step, always visible as the customer scrolls the summary.
- Collapse the order summary into an expandable accordion at the top. Let the customer focus on entering their details, not scrolling past a wall of line items.
- Kill auto-zoom on inputs. If your theme still lets iOS Safari zoom in when a customer taps an email field, fix the font-size on inputs to 16px minimum. Tiny fix, measurable lift.
- Test on a real mid-range Android, not a brand-new iPhone. Most of your customers are on the $500 phone, not the $1,500 one.
Fix 8: The Post-Purchase Upsell You’re Not Running
This one isn’t about recovering abandoned carts. It’s about squeezing more value from the ones that convert. The post-purchase upsell page — the screen between “Pay now” and “Thanks for your order” — is the single most under-used piece of real estate in ecommerce.
Why does it work? Because the hardest part of the sale is already done. The customer has entered their card, cleared their anxiety, and committed. Adding a one-click add-on at that point doesn’t trigger the same objections as a pre-purchase upsell. Well-built post-purchase offers typically lift AOV by 10-15% with zero impact on primary conversion rate.
- Use a dedicated app: ReConvert, AfterSell, or Shopify’s native post-purchase extension.
- Offer a complementary product — not a bigger version of what they just bought. A moisturiser to go with the cleanser. A battery to go with the toy.
- Anchor on a small discount: “Add this for 20% off — one time only.” The one-time framing does the heavy lifting.
- Keep it to one screen, one product. Two products on the post-purchase page actually drops take-rate by about 30%.
Fix 9: Build a Three-Email Abandonment Recovery Sequence
Even after you’ve optimised every step above, you’ll still lose 50-60% of your carts. That’s normal. The good news: a well-built abandonment recovery sequence in Klaviyo or Omnisend will recover 10-15% of those lost carts — and top-performing Shopify stores push that to 15-20% with the right copy and timing.
Here’s the sequence we deploy on every member store:
- Email 1 — 45 minutes after abandonment. Subject: “Did something go wrong?” No discount. Just a friendly nudge and a direct link back to their cart. This email alone recovers 5-8% of carts because most abandonment is accidental (dead phone, interrupted checkout, indecision).
- Email 2 — 24 hours later. Subject: “Still thinking about it?” Include a social proof block — reviews or UGC for the exact product in the cart. Still no discount. You’re removing doubt, not bribing.
- Email 3 — 72 hours later. Subject: “Last chance — 10% off inside.” This is where the discount finally shows up, and only for customers who didn’t respond to Email 1 or 2. Most brands skip the discount entirely for repeat customers to protect margin.
If you want a deeper walkthrough on the copy and segmentation behind each email, our Insights library has several pieces on the Klaviyo flows that make this sequence work. Start with the email marketing funnel article — it’s the most complete playbook we’ve published on the site.
The Compound Effect: Stack These Fixes and Watch the Scorecard Move
Here’s what matters. None of these 9 fixes on their own will 2x your business. But stacked together — and most of them are implementation, not strategy — they compound into a completely different economic reality.
Run the maths on a typical Aussie Shopify store doing $100,000 a month with a 1.5% conversion rate:
- Kill shipping shock → +8% conversions
- Turn on Shop Pay + express checkout → +9% conversions
- Enable guest checkout → +6% conversions
- Add BNPL stack → +5% conversions
- Trust signals + form friction → +3% conversions
- Post-purchase upsell → +12% AOV
- Abandonment recovery sequence → +10% recovered revenue
Compound those and you’re looking at a store that’s now doing roughly $135,000-$145,000 a month on the same traffic. No new ads. No new products. No new team. Just a checkout that doesn’t leak.
This is what we mean at eCommerce Circle when we talk about Contribution Clarity in the More Orders Operating System — the idea that every dollar that lands on your checkout should be accounted for, and the path from add-to-cart to thank-you page should be as frictionless as humanly possible. Platform fixes like these are where most of the hidden margin in a Shopify business actually lives.

Where eCommerce Circle Fits In
Inside the eCommerce Circle, checkout optimisation is one of the first Platform-layer pillars we audit with every new member. Most brands walk in convinced their biggest problem is traffic or ads. Nine times out of ten, it turns out their biggest problem is the 200 pixels between “Add to cart” and “Thank you for your order.”
If you’d like a second set of eyes on your checkout — and a clear, ranked list of the fixes most likely to move your specific numbers — we’d love to take a look. Let’s talk.
