Few things sting more than watching a customer load up their cart and then vanish. The checkout process is where the sale either closes or dies, and the numbers are brutal. According to research, 87% of shoppers will completely abandon their cart if the checkout process is too complex or lengthy. That’s not a leaky bucket — that’s a hole in the floor.

Heads up — this post may include links to things I use or like, and I might earn a little something if you shop through them. Doesn’t cost you anything extra, and I only mention stuff I’d actually recommend.
The Form That Never Ends
Every extra field in your checkout form is a tiny wall between your customer and the purchase. The average US checkout has 23.48 fields, according to Baymard Institute. Most sites can cut 20–60% of those without losing any information they actually need. That’s a lot of friction customers should never feel.
Shorter forms aren’t about laziness. They’re about respect. The moment someone has to dig for their address book or squint at a tiny dropdown, doubt creeps in. Merge First name and Last name into a single Full name field. Hide optional fields behind a link. Use autofill and geolocation to suggest city and state from a postal code. Every autocomplete you enable is a sale you keep.
- Kill the “Company” field unless you sell B2B and actually need it.
- Replace separate address fields with a single line + autocomplete.
- Move “Create an account” to after the purchase — guest checkout first.

The Hidden Cost Trap
Most people have been burned by a surprise fee. About 85% of Americans have encountered a hidden charge in the last two years, and the trust damage is immediate. A mere 14% of shoppers say they’ll leave when they can’t see the total cost upfront. But the real kicker: 55% abandon the entire brand for good after unexpected fees.
Adding a convenience fee, handling charge, or mandatory tip at the last step isn’t just annoying — it’s increasingly risky. A class‑action lawsuit against Abercrombie & Fitch in 2026 alleged a $7 handling fee hidden until final checkout. Show all costs — shipping, taxes, any extras — before the customer enters payment details. The earlier you reveal the true total, the less likely they’ll bolt.
Transparent pricing isn’t a nice-to-have; it’s a baseline expectation. If you can’t afford to absorb shipping costs, make that clear at the product page. Pair it with a clear return policy and expected delivery time. Those signals build the confidence needed to finish the purchase.

The Guest Checkout Problem
Asking a first‑time buyer to create an account before they can complete their order is like asking a stranger to sign a lease before they try on a coat. 24% of shoppers abandon the cart entirely when forced to register. And 62% of sites still fail to make “Guest Checkout” the most prominent option, according to Baymard.
The fix is simple: make guest checkout the default. Offer the option to save details after the purchase, using a passwordless account or a quick email link. That way you get the data without the friction. Some platforms, like Shopify, already support one‑page checkout and passwordless accounts — worth checking if your current cart builder does too.
You’ve been there: you find something you want, click checkout, and suddenly you’re asked to remember a password or create one. The email verification, the forgotten login, the reset email that never arrives. That’s not a moment of delight — it’s a series of small annoyances that add up to one big “never mind.”
If you’re worried about missing data, remember: you can ask for the account after the sale. And you’ll have a lot more accounts to ask if you stop losing buyers at the gate.

The Mobile Blind Spot
Nearly 76% of US adults shop primarily on their smartphones. Yet many checkout pages still treat mobile as an afterthought. Tiny tap targets, unresponsive layouts, and autofill failures are common. 88% of consumers find mobile shopping inconvenient for one reason or another — and checkout is usually the main culprit.
Mobile cart abandonment runs about 10% higher than desktop. To recover that ground, make sure your form fields are at least 45 pixels tall, with generous spacing. Use platform‑specific input types (e.g., type="tel" for phone numbers) to trigger the right keyboard. Enable autofill for addresses and credit cards.
Test your checkout flow on a real phone, every time you update. A broken button or a timeout on mobile is an instant lost sale.

Payment Options That Miss the Mark
If you’re only offering credit cards, you’re leaving money on the table. 59% of Gen Z shoppers won’t complete a purchase without their preferred online payment method, such as Apple Pay, Google Wallet, or PayPal. The same goes for buy‑now‑pay‑later services like Klarna or Afterpay for higher‑ticket items.
Beyond the payment method itself, consider the experience. Enabling one‑click checkout via a digital wallet can dramatically boost conversion. Shop Pay boosted checkout conversion by 70% at its peak, and Everlane saw a 15% increase in US transactions within 30 days of adding it. That’s the kind of lift that comes from letting customers pay the way they’re already comfortable with.
If you’re a small store, you don’t need to offer every option. Start with the two or three most popular in your region and add more as you learn what your customers actually use.

Beyond the Checkout Button
Fixing the checkout page is one of the highest‑leverage changes you can make. But it’s part of a larger funnel. The same clarity and simplicity that works at checkout should guide the entire customer journey — from the moment someone lands on your site to the post‑purchase follow‑up.
If you’re already seeing strong checkout numbers but still losing people earlier, the issue might be upstream. Things like weak lead generation, unclear landing pages, or a complicated sales process can all choke traffic before it ever reaches the cart. I’ve written about signs your landing page is losing you customers and how to reduce cart abandonment — both are worth a read if you’re plugging checkout leaks.

You don’t need a complete redesign to recover lost sales. Simplify forms, show costs upfront, let guests skip registration, optimize for mobile, and offer a payment option your customers actually use. Each fix alone can lift conversions by double digits. Together, they can recover a significant chunk of the $260 billion in recoverable orders Baymard estimates are lost every year in the US and EU.
