Express wallets promise the dream checkout: no forms, no passwords, two taps and done. Stores respond by putting the buttons everywhere, then wonder why some shoppers get lost between the cart, a wallet sheet, and a half completed guest checkout.
The button is not the strategy. Placement and shopper intent are. A wallet offered at the right moment feels like a shortcut. The same wallet pushed at the wrong moment feels like a detour the store chose for its own reasons.
The intent split at the cart
Some cart visitors are done deciding and want to pay. Others still want to check shipping costs, apply a code, or edit quantities. Wallet buttons serve the first group perfectly and frustrate the second when the wallet flow buries those tasks.
That is why the cart is the highest risk placement. Test wallet prominence at the cart separately from checkout itself, because the shopper's job is different in each place even though the button looks identical.
One home for express checkout
Pick a single, consistent home for express options, usually the top of the first checkout step, visually grouped and clearly labeled as express. Scattered buttons on the product page, cart, and every checkout step create multiple half finished paths.
Keep the standard checkout equally visible and plainly labeled. Shoppers who do not use wallets should never feel they found the back door. Confidence in the normal path is part of what makes the express path feel safe to try.
What the wallet hides, the store must surface
Wallet flows collect payment and address inside the wallet, so shipping options, taxes, and totals may appear late. A surprise shipping charge after a two tap flow feels like a trap, even when the math is honest.
Stores should preview shipping costs before the wallet opens wherever possible, and reconcile the wallet total with the order review step. The review step after an express payment is not friction, it is the shopper's only chance to catch an old address.
Reading the results without fooling yourself
Wallet users often convert better because they were already high intent, not because the button converted them. Compare overall checkout completion, not wallet user completion, before declaring victory.
Watch error and duplicate order rates too. Confused express flows produce double submissions and wrong address orders that quietly eat the conversion gain in support and reshipping costs.

Frequently asked questions
Where should wallet buttons be placed?
In one consistent place, most often the top of the first checkout step, clearly grouped as express checkout, with the standard checkout just as visible. Avoid scattering them across product, cart, and every step.
Do wallet buttons always raise conversion?
No. They help high intent shoppers with saved details, but they can confuse shoppers who still need shipping costs, codes, or edits. Measure total checkout completion, since wallet users are often higher intent to begin with.
Why did a shopper end up with an old address?
Wallet flows ship to the address saved in the wallet, which may be outdated. An order review step after express payment, showing the delivery address plainly, is the main defense.
Should express buttons appear on product pages?
They can work for single item, known product purchases, but they bypass the cart where many shoppers check totals and codes. Test them separately and watch support contacts, not just clicks.
