Checkout Friction: The Most Common CRO Issue in eCommerce
Last updated: July 2026 · By The CROBenchmark Team
Checkout friction is any point in the payment flow that adds hesitation, cognitive load, or an unexpected step between a shopper deciding to buy and finishing the purchase. Across 7,000+ stores in the CROBenchmark dataset, benchmarked against 248+ audit criteria in 15+ industries, checkout friction is the single most common conversion barrier the audit surfaces, present in more audited stores than any other category [CROBenchmark Report 2026, Omniconvert]. You can see your own store's specific checkout friction points with a free CROBenchmark audit.
Quick answer. Checkout friction is any element of the payment flow that adds hesitation or an unexpected step, such as excessive form fields, forced account creation, and shipping costs disclosed late. It is the most common conversion barrier CROBenchmark identifies across audited stores, and each cause is independently fixable and independently testable.
What counts as checkout friction, specifically?
Checkout friction is not a vague feeling, it is a set of concrete, checkable moments where a ready-to-buy shopper hesitates. The four most common are too many form fields, forced account creation before payment, shipping costs revealed late in the flow, and a missing or hard-to-find guest checkout option.
Defining the term precisely matters because "improve checkout" is not an action, while "cut the checkout from 14 fields to 8" is. Each of the four causes maps to a specific, measurable change: field count is a number you can reduce, forced signup is a toggle you can remove, shipping cost timing is a disclosure you can move earlier, and guest checkout is an option you can expose. Treating friction as these discrete, testable items is what turns a general complaint into a prioritised list of experiments. This is the finding-to-hypothesis method: every audit finding becomes a single falsifiable test rather than a line on an open-ended to-do list. It also keeps the work honest, because a hypothesis has a pass-or-fail outcome, while "make checkout better" never does. CROBenchmark applies the same 248+ criteria to every store it scores, so the friction it flags is comparable across 15+ industries and 8 platforms rather than a matter of whichever item a reviewer happened to notice first.
Why checkout friction is the most common CRO issue
Checkout friction tops the finding list because it is both widespread and easy to overlook from inside the business. A store owner who has completed their own checkout hundreds of times stops seeing the extra field or the shipping surprise that a first-time buyer meets cold, which is exactly why an outside audit catches it.
The external data lines up with what the audit sees. The Baymard Institute puts average documented cart abandonment at roughly 70%, and its research repeatedly finds that unexpected extra costs, shipping, taxes, and fees revealed late, are the single most cited reason shoppers leave a checkout [Baymard Institute, 2025]. Layer on the fact that mobile now accounts for the majority of eCommerce traffic [Statista, 2025], where small screens make long forms and surprise costs even more punishing, and it becomes clear why checkout is where the most revenue leaks. The friction was always there; most stores simply never measured it against a fixed criteria set.
The pattern shows up constantly in founder communities too. A recurring r/shopify question runs some version of "my traffic and add-to-carts look healthy but sales are flat, what am I missing?" The answer is almost always downstream: a checkout asking for a phone number it never uses, a shipping cost that only appears on the final screen, or a signup wall standing between an eager buyer and the pay button. None of these feel like a problem to the person who built the store, which is why they persist until something scores them from the outside.
Which checkout friction issues appear most often across audited stores?
Excessive form field count and late-disclosed shipping costs are the two checkout issues flagged most frequently in CROBenchmark audits, both common precisely because they are hard for an internal team to notice without an outside review. The table below shows how often each issue is found across the dataset and the typical conversion uplift seen when a winning fix is shipped.
| Checkout friction issue | Frequency across stores | Typical CVR uplift when fixed |
|---|---|---|
| Excessive form fields | 58% | +10% |
| Shipping costs disclosed late | 51% | +14% |
| Forced account creation | 39% | +12% |
| No or hidden guest checkout | 34% | +11% |
| Too few payment options | 29% | +6% |
Read this as a probability map for your own checkout rather than a promise. If you have not audited the flow, the base rate says there is better than even odds you are asking for more fields than fulfillment needs or revealing shipping too late, and either one is worth a double-digit lift on the step it sits on. The audit tells you which of these apply to your store specifically and in what order to test them.
How to fix checkout friction without a full checkout rebuild
Most checkout friction fixes do not require a rebuild or a redesign, they are incremental changes you can test inside your platform's existing checkout options. Reducing form fields, surfacing shipping costs earlier, and enabling guest checkout are the highest-return moves most stores can make first.
- Cut the form to what fulfillment actually needs. Remove optional fields, use address autocomplete, and infer what you can (city and state from a postal code) so the shopper types less. The Baymard Institute finds the average checkout carries far more fields than fulfillment requires [Baymard Institute, 2025], which makes this the most common quick win.
- Show shipping cost before the final step. Add a shipping estimator or a clear cost line early so the total is never a late surprise, the abandonment trigger buyers cite most.
- Enable guest checkout. Let shoppers buy without creating an account, then offer signup on the confirmation page once the purchase is done, keeping the forced-signup barrier out of the highest-intent moment.
- Widen payment options. Add the wallets and methods your audience already uses so nobody stalls for lack of a familiar button.
On Shopify, field reordering, guest checkout, and several trust and payment settings are configuration changes available without a developer, while a custom shipping estimator or a bespoke one-page checkout may need build support. The discipline is the same either way: change one thing, run it to significance, keep the winners. This is where 13 years of Omniconvert CRO experimentation shows its value, the highest hit rate comes from testing the findings most likely to move revenue, not the ones easiest to spot.
What checkout friction actually costs: a worked example
The value of removing friction becomes concrete when you trace one issue through to a result. The path is always the same: a finding becomes a hypothesis, the hypothesis becomes a test, and the test either ships as a permanent gain or becomes a documented learning about your buyers.
Take the most-flagged pairing in the table, a checkout that both asks for account creation before payment and reveals shipping cost only on the final step. That becomes two hypotheses: removing forced account creation will lift checkout completion, and surfacing shipping cost earlier will cut last-step abandonment. Each runs to significance on real traffic. In the pattern seen across the dataset, a winning guest-checkout variant lands around an 11% to 12% lift and an earlier shipping-cost fix around 14%, and on a store with meaningful checkout volume either change on its own can outweigh the entire cost of the audit and the testing tool combined. The audit did not guarantee the win, it pointed at the highest-probability place to look first, which is the whole point. Not every test wins, and a sound programme budgets for that: each losing variant still teaches you what your shoppers do not respond to, sharpening the next hypothesis. For a fuller walkthrough of turning findings into revenue, Omniconvert has documented the approach across 13 years of conversion case studies.
Limitations of this checkout friction data
These figures are a directional starting point, not a guarantee for any one store, and three limitations are worth stating plainly before you act on them.
First, the frequencies and uplifts are dataset patterns: they describe how often an issue shows up and the typical result when a winning variant is found, not what your specific checkout will do. Second, uplift depends on volume, below roughly a few thousand checkouts a month you may not reach statistical significance, so treat the audit as a design guide rather than a testing plan. Third, checkout is point-in-time, a platform update or a new payment integration can reopen a finding you had cleared, which is why a checkout audit is worth repeating after any material change. Confirm the size of each opportunity with a live test on your own traffic before treating any number here as your own.
Frequently asked questions
What is checkout friction?
Checkout friction refers to any element of the payment flow that adds hesitation or unexpected steps for a shopper, such as too many form fields, forced account creation, or late-disclosed shipping costs.
What is the most common checkout issue in ecommerce?
Excessive form field count and late-disclosed shipping costs are among the most frequently identified checkout issues across CROBenchmark audited stores.
Does guest checkout actually improve conversion?
Enabling guest checkout removes a forced-signup barrier at the point of highest purchase intent, and it is consistently one of the higher-impact, lower-effort checkout fixes identified in CRO audits.
How many form fields should a checkout have?
There is no universal number, but reducing checkout fields to only what is strictly necessary for fulfillment (typically far fewer than most default checkout flows include) is a common, testable improvement.
Can I fix checkout friction without a developer?
Many fixes, like enabling guest checkout or reordering form fields, are available through standard Shopify checkout settings. More involved changes, like a custom shipping estimator, may need development support.
The bottom line
Checkout friction is the most common CRO issue for a simple reason: it is everywhere and it is hard to see from the inside. The fix is not a rebuild, it is a ranked set of small, testable changes to fields, shipping disclosure, guest checkout, and payment options. Start with a free CROBenchmark audit to find your store's specific friction points, then move to the $29.99 full audit for the prioritised list across 248+ criteria that turns those findings into a checkout testing roadmap.
