A sticky add to cart bar is a small idea with a fiddly implementation, and the fiddliness is why some of them feel wrong. These install as app embeds, and Shopify documents that an app embed block only has access to the global Liquid scope of the page it renders on. The product is not in that scope. So the bar cannot simply read your variants the way your theme does; it has to go and fetch them, which is where a bar that shows the wrong price for a second, or misses a variant, comes from.

Changing a variant from the bar has the same shape of problem. The storefront endpoint for changing a cart line updates quantity, properties and selling plan only, so swapping a size is a removal followed by an add rather than a change. And the express payment button is the strictest case of all: the theme renders it inside a product form, Shopify picks which single button to show, and its markup lives inside a closed shadow DOM where any styling or event tracking aimed at the structure will not work.

What to look for in a Boton De Compra app

Whether it agrees with the page behind it: Pick your most complicated product and watch the bar as you change options: price, availability, the selected variant and the button state all have to follow. A bar that stays on the default variant is worse than no bar, because it takes orders for the wrong thing.
What it does on a phone: This is a mobile feature first, and mobile is where it collides with everything else you have pinned to the bottom of the screen: a chat bubble, a cookie banner, a sales notification. Look at the real page with all of them running.
Express checkout, or not: A wallet button in the bar shortens the path and brings the constraints above with it, including limited restyling. If the vendor shows a heavily branded express button in screenshots, ask how, because Shopify only exposes custom properties for that element.
How much else comes with it: Some listings here are a single lightweight bar and others are cart drawer and upsell suites where the bar is one feature. Both are fine; paying suite prices for a bar, or installing a suite you will not configure, is not.

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →
