How to set up an online store checkout that actually converts

A shopper adding something to their cart is the easy part. Getting them through checkout is where most online stores actually lose the sale, industry data consistently puts average cart abandonment somewhere around 70%, and a meaningful chunk of that is checkout friction you can fix, not just people window shopping. This guide covers the specific, practical changes that move the needle: what to remove from your checkout flow, which payment options actually matter, and how to keep fraud protection from quietly rejecting good customers.

If you're still choosing how to accept payments on your store in the first place, read our guide to online payment processing for small business first, then come back here to tighten up the checkout experience itself.

Why do shoppers abandon their cart at checkout?

The most common reasons are remarkably consistent across studies and merchant data: extra costs revealed too late, being forced to create an account, a checkout process that's too long, not trusting the site with card details, and a slow or clunky mobile experience. None of these require a redesign of your whole store, they're checkout-specific fixes.

Should you require an account to check out?

No, or at least, not as the only option. Forcing account creation before checkout is one of the most consistently cited reasons shoppers abandon a cart, especially first-time buyers who just want to complete a single purchase without committing to a login. Offer guest checkout prominently, and let shoppers create an account afterward if they want to, using the information you already collected during the order.

• Make guest checkout the default, visually equal or more prominent than "create an account."
• Offer a post-purchase account creation option, most shoppers who'll make an account will do it once the friction of buying is already gone.
• If you want repeat customers, an email capture at checkout with a simple password-free login link works better than a forced signup.

How many steps should checkout have?

As few as you can manage while still collecting what you need. A single-page checkout that shows contact info, shipping, and payment together generally outperforms a multi-page wizard, since every additional page is another chance for someone to get distracted or give up. If your platform only supports multi-step checkout, keep it to two or three steps maximum and show a progress indicator so shoppers know how much is left.

• Auto-fill city and state from a ZIP code instead of asking for both.
• Don't ask for a phone number unless you genuinely need it for delivery.
• Pre-select the most common shipping option rather than leaving it blank.
• Let returning customers autofill saved payment and address details.
• Show a persistent order summary so shoppers don't need to scroll back to double check what they're buying.

What payment options should you offer?

Card payments remain the default, but the payment options around them matter more every year, especially on mobile. Digital wallets like Apple Pay and Google Pay let a shopper pay with a fingerprint or face scan instead of typing out sixteen digits, an expiration date, and a CVV on a phone keyboard, that alone measurably reduces abandonment on mobile checkouts.

• Apple Pay and Google Pay, fast, secure, and increasingly expected by mobile shoppers.
• Standard card entry with autofill support, make sure your checkout page correctly triggers the phone's saved-card autofill.
• PayPal or similar, still popular with a segment of shoppers who prefer not to enter card details directly on unfamiliar sites.
• Buy-now-pay-later options like installment plans, can lift average order value, but come with their own fees and are best suited to higher-ticket items.
• ACH or bank transfer for large B2B or wholesale orders, which is often cheaper than card fees at high order values, see our ACH payments guide.

How does checkout speed affect conversion?

A slow-loading checkout page costs you sales in a very direct way, every extra second of load time increases the chance a shopper closes the tab, especially on mobile data. Common culprits are heavyweight images on the checkout page itself, too many third-party scripts (analytics, chat widgets, retargeting pixels) loaded on the payment step, and a payment gateway that redirects to a separate slow-loading page instead of embedding cleanly.

• Strip unnecessary scripts and widgets from the checkout page specifically, even if you keep them elsewhere on the site.
• Use an embedded payment form rather than a full redirect to a separate host, where it's supported by your provider.
• Compress or remove large images near the checkout flow.
• Test load time on a real phone on cellular data, not just wifi on a fast laptop.

How do you show shipping and taxes without surprising people?

Hidden costs revealed at the very last step is one of the single biggest drivers of abandoned carts. Shoppers who get to the final payment screen and see an extra $12 in shipping they didn't expect will often just leave rather than continue. Show an estimated total, including shipping and tax, as early in the process as you reasonably can, ideally right on the cart page, before checkout even starts.

• Add a shipping estimator directly on the cart page using ZIP code.
• Consider free shipping above a threshold, clearly stated, rather than a flat unexpected charge.
• Show tax as a clearly labeled line item, not folded silently into the total.
• If a coupon code field is empty and visible, some shoppers will leave to search for a code, consider hiding it behind a small link instead.

How do you keep fraud tools from blocking real customers?

Fraud protection matters, especially for card-not-present sales which carry more chargeback risk than in-person transactions, but overly aggressive rules can quietly decline good customers without you ever knowing it happened. A shopper whose card gets falsely declined rarely calls to complain, they just leave and buy from a competitor.

• Use address verification and CVV matching as signals, not automatic hard declines, where your gateway allows tuning.
• Review your decline rate periodically, a rate that seems unusually high for your industry may mean rules are set too strictly.
• Give a clear, specific error message on a decline rather than a vague failure, so a customer can retry with a different card.
• Balance this against real risk, our how to prevent chargebacks guide covers the other side of this tradeoff.

What should you measure to know if checkout changes are working?

Track your checkout conversion rate, the share of people who start checkout and complete it, separately from your overall site conversion rate. Most e-commerce platforms and payment gateways report this directly. Make one change at a time where you can, whether that's adding a wallet option or removing a form field, and watch the number for a couple of weeks before drawing conclusions, since day-to-day traffic swings can be noisy.

What does this look like for Minnesota businesses?

Minnesota's e-commerce and retail businesses compete with the same national players everyone else does, which makes checkout experience one of the few things fully within a small business owner's control. We work with online sellers across Minneapolis, St. Paul and Minnesota to connect the right payment gateway to their storefront platform and clean up checkout flows that are quietly losing sales.
