Cart abandonment feels discouraging when you first see the number — most online stores lose the majority of carts before checkout completes — but the more useful way to look at it is that a large share of that abandonment is genuinely fixable friction, not lost interest.
The single biggest lever is unexpected costs appearing late in checkout. A customer who adds an item expecting a certain total, only to see shipping and fees added at the final step, is far more likely to abandon than one who saw the full cost upfront. Showing shipping estimates early, ideally on the product page itself, removes one of the most common triggers for last-minute drop-off.
Account creation requirements are another quiet killer. Forcing a new account before checkout adds friction at exactly the moment a customer wants the process to be as short as possible. Offering a genuine guest checkout option, with an easy path to create an account afterward, consistently improves completion rates.
Recovery emails are the highest-leverage fix once abandonment has already happened. A well-timed reminder — sent an hour or two later, not immediately — recovers a meaningful share of carts on its own, especially when it addresses the likely reason for hesitation directly rather than just repeating "you left something in your cart."
Beyond these, page speed and a checkout that works cleanly on mobile matter just as much here as anywhere else on the site — checkout is the worst possible place for a slow page or an awkward form, because it's the final moment before a sale is either completed or lost.
None of these fixes require a full store rebuild — most can be tested and shipped within a week, and because checkout is such a high-leverage part of the customer journey, even a modest improvement in completion rate here tends to be one of the most cost-effective changes a store can make.
