The Checkout Is Where Your Ecommerce Revenue Leaks Out
Seven in ten carts never convert, and most of that loss is self-inflicted at checkout. Here is what the data says is leaking, and the fixes that earn the order back.
You can pour budget into ads, SEO, and a beautiful storefront, and still watch most of your revenue walk out the door at the final step. For the average online store, roughly seven in ten shoppers who add something to the cart leave without buying. The encouraging part is that most of that loss is not about price or intent. It is friction you built, which means it is friction you can remove.
Seven in ten carts never make it to a receipt
The average documented online cart abandonment rate is 70.22 percent, drawn from 50 separate studies (Baymard Institute, 2025). Read that back slowly. For every ten people motivated enough to choose a product and add it to the cart, about seven leave before the order is placed.
Some of that is unavoidable. People comparison shop, save carts for later, and browse with no intention to buy. But when you set the browsers aside and ask the people who genuinely wanted to buy why they stopped, the reasons are strikingly fixable.
The leak is mostly self-inflicted
Among shoppers who abandoned a checkout they actually intended to complete, the top reasons are not mysterious (Baymard Institute, 2025):
- Extra costs like shipping, tax, and fees were too high, or showed up too late: 39 percent.
- The site forced them to create an account: 19 percent.
- The checkout was too long or too complicated: 18 percent.
- They could not see or calculate the total cost up front: 14 percent.
Why motivated buyers abandon checkout
Notice what these have in common. None of them is "your product is wrong" or "your price is too high." They are all about how and when effort and information get demanded. A surprise shipping cost on the final screen. A mandatory account wall. A checkout that sprawls across too many fields and steps.
Each one is a decision someone made during the build, and each one can be unmade.
Four fixes that recover orders
Show the full cost early, not at the finish line
The single biggest abandonment driver is unexpected cost. Put shipping, tax, and fees in view as early as the cart, or give a clear estimator before the final step. A total that only appears on the last screen feels like a bait and switch, even when the number is fair. Buyers do not quit because shipping exists. They quit because it ambushed them.
How to do it
- Turn on a cart-page shipping estimator that takes a ZIP or postal code (through your platform's shipping settings, or a Shopify cart shipping-calculator app) so shoppers see a real number before they reach checkout.
- Prefer flat-rate or table-rate shipping where you can, since carrier-calculated rates only resolve after an address is entered at checkout and cannot be shown earlier.
- Add tax and any handling or service fees as their own line in the cart summary, label anything that is an estimate, and update it live as quantities change.
- For oversize, international, or installation charges, state or estimate them on the product page, not at the finish line.
See a worked example
Say a home-goods store moves shipping and tax out of the final review screen and into the cart drawer, with a ZIP-code estimator that fires as soon as the first item is added. In a setup like this you might reasonably see the drop-off on the payment step ease once the total stops jumping at the last screen, and support tickets about surprise shipping tend to fall alongside it.

Act as a conversion-focused ecommerce UX reviewer. Here is my current checkout flow and where each cost currently appears: [describe the cart, shipping step, tax step, and the final review screen, or paste screenshots or HTML]. My platform is [Shopify, WooCommerce, or other] and my shipping method is [flat rate, table rate, or carrier-calculated]. Trace exactly where a shopper first sees shipping, tax, and fees, flag any cost that only appears at the final step, and give me a prioritized list of changes to surface the full total as early as the cart, including whether I should switch shipping methods or add a ZIP-code estimator. Keep every recommendation specific to my platform and note anything that is not technically possible on it.
Offer guest checkout
Forcing account creation costs you nearly one in five motivated buyers. Let people check out as guests, then invite them to save their details after the order is placed, when the value of an account is obvious and the risk of losing the sale is gone. You still capture the email at purchase. You just stop asking a first-time buyer to commit before they are ready.
How to do it
- Make accounts optional so guest checkout is allowed. In Shopify, open Settings, then Checkout, then Customer accounts and set them to optional; in WooCommerce, open Settings, then Accounts and Privacy, and allow customers to place orders without an account.
- On the account-selection step, make "Continue as guest" the top, most prominent button, above sign-in and create-account options, instead of a buried text link.
- Keep the email field inside the guest flow so you still capture the purchase email for the receipt and any follow-up.
- On the order-confirmation page, add a one-click "Save my details" or "set a password" prompt so account creation is invited after payment, not required before it.
See a worked example
A home-goods store that had buried "Create account" fields on its account step replaced them with a prominent "Continue as guest" button at the top, kept the email field so it still captured every buyer's address, and added a single "Save my details for next time?" prompt on the order-confirmation page. In a scenario like this you would typically expect the drop-off at the account step to fall noticeably, and a modest but real share of buyers to opt into an account after paying rather than before.

Act as a conversion-focused ecommerce UX reviewer. I run a [describe store: platform, for example Shopify or WooCommerce] selling [describe products] and want to add or fix guest checkout without losing the ability to capture emails or invite account creation. Here is my current account and checkout step: [paste the copy, button labels, field order, and settings]. Tell me (1) whether guest checkout is offered and prominent enough per checkout-UX best practice, (2) the exact settings changes to make accounts optional and guest checkout the top button, (3) how to keep capturing the buyer's email in the guest flow, and (4) the wording and placement for a post-purchase "save your details or create a password" prompt on the order-confirmation page. Do not invent statistics; give concrete label and layout suggestions I can implement today.
Shorten the form to what you truly need
Most checkouts ask for more than the order requires, and every extra field is another small reason to quit. Combine steps, cut optional fields, autofill where you can, and default to a single-column flow that behaves on a phone. The goal is the shortest honest path from cart to confirmation.
How to do it
- List every field in your current checkout and mark each one required, optional, or derivable, then cut or hide the optional ones (put Address Line 2 and the coupon field behind a link, and default billing to shipping).
- Merge first and last name into a single "Full name" input and combine steps so the whole flow reads top to bottom in one column, with only short related fields like City, State, and ZIP sharing a row.
- Add the correct HTML autocomplete token to every input you keep (name, email, tel, street-address, postal-code, cc-number, cc-exp), using MDN's token list, so browsers autofill instead of making users type.
- Test the shortened single-column flow on a real phone in both Chrome and Safari, confirming autofill populates fields and nothing forces horizontal scrolling or zoom.
See a worked example
A B2B store trimmed a 14-field checkout to 8 by merging first and last name into one "Full name" input, hiding Address Line 2 and the coupon field behind links, and defaulting billing to the shipping address. In a case like this, mobile completion often improves noticeably over the following weeks once browser autofill starts firing cleanly.

Here is my current ecommerce checkout, field by field: [paste every field label, whether it is required, and which step it sits on]. My product is [describe what you sell and whether you ship physical goods]. Act as a checkout UX reviewer aiming for the shortest honest path from cart to confirmation: for each field tell me keep, cut, merge, or hide-behind-a-link and why; propose a single-column, mobile-first field order that keeps only short related fields (City, State, ZIP) on the same row; give me the exact HTML autocomplete token for every field I keep (for example name, email, tel, street-address, postal-code, cc-number, cc-exp); and flag anything I am collecting that I do not strictly need to fulfill the order.
Earn trust at the moment of payment
A lack of trust around card details drives abandonment too. Familiar payment options, visible security cues, a clear returns policy, and no unexplained redirects all reassure a buyer at the exact moment they feel most exposed. Trust is not a badge you paste on. It is the sum of small signals that say this is safe.
How to do it
- Offer the payment methods your buyers already recognize: enable express wallets like Apple Pay and Google Pay plus PayPal alongside cards through your processor (Stripe, Shopify Payments, or Adyen).
- Keep payment on your own domain. If a redirect to a gateway is unavoidable, tell the buyer it is coming before it happens, and carry your logo and colors through the handoff so nothing feels off.
- Put a plain security cue and a one-line returns note right next to the card fields (a padlock plus "secure, encrypted" wording), not buried in the footer where nobody looks at the point of payment.
- Test the full flow on a phone and confirm HTTPS, the padlock, and any trust badge render correctly on the actual payment screen.
See a worked example
Picture a B2B supplier whose checkout bounced buyers to an unbranded third-party payment page with no logo and no security note, and payment-step drop-off was its worst leak. After keeping payment on its own domain, adding Apple Pay and PayPal beside the card fields, and placing a short "secure, encrypted checkout, 30-day returns" line under the pay button, abandonment at that step tended to ease and completed orders often ticked up over the following weeks.

I'm reviewing the payment step of my ecommerce checkout so buyers feel safe enough to complete the purchase. Here is my current payment step: [describe or paste the payment methods offered, whether payment stays on my domain or redirects to a gateway, and where any security badges or returns policy currently appear]. My audience and typical order value are [describe]. Drawing on established checkout UX research (for example Baymard Institute and Nielsen Norman Group) and PCI guidance, tell me which familiar payment options I may be missing for this audience, exactly where to place security cues and a short returns note so they are visible at the moment of payment, any unexplained or unbranded redirects that could scare buyers off, and the three highest-impact changes to make first. Give specific, concrete edits I can implement, and flag anything that would be a false security claim.
The upside is measured, not hoped for
This is where checkout work separates itself from most growth hacks: the payoff is documented. Baymard's decade of large-scale checkout testing finds that the average large ecommerce site can lift conversion by roughly 35 percent through checkout design improvements alone, with a typical site carrying dozens of fixable issues (Baymard Institute). That is not a rounding error. It is a different revenue line pulled from the same traffic you already pay for.
It also compounds with everything else you are doing. A store on the right platform still leaks if the checkout is clumsy, which is why the platform decision and the checkout experience have to be solved together, not in isolation.
Fix it like a system, not a guess
One caution. The instinct after reading a list like this is to change all four things at once and hope the number moves. That is how teams end up unable to tell what actually worked, or worse, shipping a change that quietly hurt. The durable version is to treat the checkout as a system you improve and measure on purpose, the same discipline that separates real conversion gains from tests that only look like wins. Fix the biggest friction first, confirm the lift is real, then move to the next one.
That is exactly the work our Conversion System is built to run: find where the revenue leaks, fix the highest-impact friction, and prove the gain rather than assume it.
