Checkout Flow Optimization: the 6 Friction Points Hiding in Plain Sight

Joona Heinonen· Choco Media · Rovaniemi

Checkout flow optimization is one of the highest-leverage things you can do in e-commerce — and yet most stores leave it almost entirely untouched. At Choco Media, when we audit a client’s store, we rarely need to look further than the checkout to find where revenue is quietly disappearing. The friction is almost always hiding in plain sight: six recurring patterns that show up again and again regardless of platform, product, or price point.

This post is for anyone running an online store — Shopify, WooCommerce, whatever — who knows their traffic is decent but conversion feels lower than it should be. We’ll walk through each friction point with specific things to look at and specific things to change. No CRO theory, no benchmarks that don’t apply to your context. Just the patterns we’ve seen reduce checkout abandonment in real accounts.

A quick note on scope: we’re talking about the checkout itself — from the moment a user clicks “buy” or “add to cart” through to order confirmation. Cart page optimisation is a related but separate topic. These are the six steps inside the checkout where most stores lose the most people.

1. The Forced Account Barrier

If your checkout requires account creation before purchase, you’re filtering out a significant share of otherwise willing buyers. This is the single most well-documented checkout friction point in e-commerce, and it still trips up stores every year — usually because it was set as the default during setup and nobody thought to question it.

The fix is straightforward: offer guest checkout as the primary path, and make account creation an optional step after the purchase confirmation. Most platforms support this natively. On Shopify, it’s a single toggle in checkout settings. On WooCommerce, it’s a checkbox in the checkout options.

In client work we’ve found that even stores with returning customer rates above 30% see checkout conversion improve when guest checkout is foregrounded. Returning customers who want to log in will find the option. New customers shouldn’t have to step over it.

One edge case worth noting

Subscription products are an exception — account creation is often necessary for managing subscriptions. In those cases, set the expectation early (on the product page or in the cart) so the checkout requirement doesn’t feel like a surprise.

2. Form Fields You Don’t Actually Need

Every additional field in a checkout form is a micro-decision that costs the user cognitive effort. Most stores ask for more than they need — a second address line that could be optional, a phone number field marked required when it’s only used for delivery notifications, a company name field shown to all users even when most are buying personally.

The principle here is simple: only collect what you need to complete the transaction and fulfil the order. Everything else is friction.

Address autocomplete is also worth implementing if you haven’t already. Google Places API integration is available on most platforms and meaningfully reduces the effort of filling in address fields — users type 3-4 characters and confirm rather than typing every field manually.

“The best checkout form is the one the user barely notices. Every field that earns its place is invisible; every field that doesn’t is a reason to leave.”

3. Unexpected Costs at the Final Step

Checkout abandonment spikes when the total on the order summary page is meaningfully higher than what the user expected. Shipping costs are the most common culprit, but VAT display (especially for B2C stores in VAT-inclusive markets like Finland), currency conversion fees, and handling charges all cause the same effect: the user feels surprised, and surprise at this stage feels like being misled.

The goal isn’t to hide costs — it’s to surface them before the user reaches checkout so the final total is a confirmation rather than a revelation.

If your shipping costs are genuinely high relative to order value (common in low-AOV stores or when shipping bulky products), consider whether a flat-rate or free-shipping-above-threshold model would recover more in conversion than you’d lose in margin. In many cases it does.

4. Trust Signal Absence at the Payment Step

The moment a user is about to enter their card details is the moment they are most primed to reconsider. This is where trust signals matter most — and where many stores either display them inconsistently or rely on generic elements that don’t do much work.

Trust signals at checkout fall into two categories: security signals (this transaction is safe) and social signals (other people have bought here and been happy). Both are useful. Security signals are table stakes; social signals are often under-deployed.

For stores using our conversion rate optimisation service, this is one of the first areas we instrument — session replay at the payment step often reveals hesitation patterns (repeated scrolling, mouse movements toward the back button) that indicate where specific trust signals are missing.

Payment method coverage

In Finnish and Nordic markets, local payment methods matter. If you’re selling to Finnish consumers and not offering Finnish bank payments (MobilePay, Paytrail, bank buttons), you’re likely losing a material share of transactions that would otherwise complete. This isn’t a checkout UX issue per se — it’s a payment infrastructure decision — but the conversion impact is just as direct.

5. Mobile Checkout That Was Designed on Desktop

In most e-commerce stores, more than half of sessions happen on mobile — but checkout flows are often designed and tested primarily on desktop. The result is a mobile checkout that technically works but is full of small frictions: tap targets that are too small, keyboard types that don’t match the input (numeric keyboard not triggered for phone number fields), multi-column layouts that become confusing in a single column, and progress indicators that are cut off on smaller screens.

A mobile checkout audit should cover at minimum:

Apple Pay and Google Pay are worth special mention. For mobile users who have them set up, they collapse the entire payment step into a single tap — removing address entry, card entry, and the majority of checkout friction in one move. If you’re not offering them, enabling them is one of the higher-return technical investments in checkout optimization.

6. The One-Page vs Multi-Step Decision Made Badly

One-page checkout and multi-step checkout each have genuine advantages, and the conversion difference between them depends heavily on context — product type, average order value, amount of information required. What we see in practice is that many stores are using one format or the other for no deliberate reason: it was the default, or someone changed it years ago and nobody knows why.

The relevant question isn’t “which format converts better in general?” — it’s “which format reduces confusion and perceived effort for our specific customer completing our specific checkout?”

If you haven’t deliberately chosen your checkout format with these considerations in mind, it’s worth testing. The caveat is that checkout A/B testing requires meaningful traffic volume to reach significance quickly — which connects to broader questions about how to structure tests for lower-traffic sites, something we cover in our guide to A/B testing for small sites.

How to Prioritise These Six Fixes

Not all six friction points will be present in your checkout, and not all of them will have equal impact. Here’s a rough prioritisation framework based on the frequency and magnitude of impact we see in audits:

The most efficient way to work through these is to combine quantitative data (where in the checkout funnel are you losing the most users?) with qualitative data (session replay of those drop-off points). Funnel analysis tells you where to look; session replay tells you what people are actually doing when they leave.

This is a significant part of what our website and funnel service covers — not just identifying where conversion is leaking but instrumenting the right data to understand why, then building and testing the fixes systematically.

One More Thing: the Post-Purchase Experience

Checkout optimisation typically focuses on getting users through to purchase, but the order confirmation page and confirmation email are also part of the checkout experience — and they’re frequently left as platform defaults.

A well-crafted order confirmation does several things: it reduces buyer anxiety (the purchase definitely went through), it sets expectation for what happens next (shipping timeline, tracking), and it presents a moment to either upsell or reinforce the decision to buy. Most stores do none of these deliberately.

None of this requires custom development on most platforms. It requires intentional configuration and copy — which is often faster to improve than the checkout form fields themselves.

Where to Start If You’re Not Sure

If you’re looking at this list and unsure which of these applies to your store, start with a structured checkout walkthrough: complete a full purchase on your own store, on mobile, on a slow connection, as a guest. Note every moment of hesitation or confusion. Then do it again in session replay with 10 real users.

That combination will surface your highest-priority friction points faster than any benchmark or checklist. The six patterns above are a map of where to look — but the specific issues in your store are visible in your own data.
