Checkout friction is one of the most expensive forms of waste in e-commerce. The brand has paid for the visit, earned enough interest to reach checkout, and then loses the customer at the final hurdle.
In 2026, mobile expectations, payment choice and delivery transparency make this harder to ignore.
Checkout starts before the checkout page
Many checkout problems begin on product and basket pages. If delivery cost, returns policy, sizing, stock status or payment options are unclear, the customer carries doubt into the final step.
By the time doubt reaches checkout, the brand has to work harder to keep the sale. It's usually better to remove uncertainty earlier.
Mobile shoppers have less patience for friction
On mobile, small points of friction become larger: slow loading, cramped forms, poor address lookup, hidden costs, weak error states or payment options that require too much typing.
A mobile checkout review should follow the customer from product page to confirmation, not just inspect the final form.
Payment choice is part of conversion strategy
Digital wallets, buy now pay later and local payment methods aren't just operational options. They affect confidence, convenience and affordability at the moment of decision.
That doesn't mean every brand needs every payment option. It means payment choice should reflect audience, average order value, margin and risk.
Measure the leak properly
Brands should review add-to-cart rate, checkout start rate, checkout completion, device split, payment failures, delivery-related exits and support queries around ordering.
The aim is to find the avoidable points of hesitation. Fixing one of them can improve the economics of every acquisition channel.
