A sticky add to cart bar is a thin strip that pins to the top or bottom of the screen once a shopper scrolls past the main Add to Cart button on a WooCommerce product page, keeping the product name, price, and a working add-to-cart button in view the whole time they’re reading. This post compares three real, dedicated plugins that do it: WPC Sticky Add To Cart (fully free, no upgrade path), Simple Sticky Add To Cart For WooCommerce (free with a $39/year Pro tier for styling and Ajax add-to-cart), and Sticky Product Add to Cart and Checkout Bar (the only one of the three that also sticks a bar to the cart and checkout pages, though its last update predates two WordPress majors). None of them is a ConicPlex product; this is a genuinely third-party comparison.
Most “boost your WooCommerce conversion rate” roundups mention sticky add-to-cart bars as one bullet point in a list of twelve tactics, then move on to social proof popups and countdown timers without naming a single plugin. That’s the gap here. If a shopper scrolls two screens down into a long product description, a spec table, and a review section, the button they need to actually buy the thing has usually scrolled off the top of the page with everything else. A sticky bar solves exactly that, and exactly one feature, which is why it’s worth comparing on its own instead of buried in a general list.

WPC Sticky Add To Cart
WPC Sticky Add To Cart, built by WPClever, does one thing and charges nothing for it. The bar shows a product thumbnail, price, a quantity input, and the Add to Cart button, and you choose whether it docks to the top or the bottom of the screen. There’s no premium tier gating any of that: everything in the description is what you get after activation, which is unusual in a category where most competitors hold back at least the styling or the Ajax behavior for a paid upgrade.
- Price: Free
- Requires: WordPress 5.9+, PHP not specified by the plugin

Setup is exactly as short as the plugin itself: go to Plugins > Add New in your dashboard, search for “WPC Sticky Add To Cart,” install and activate it, then open its settings page to pick top or bottom placement and toggle the quantity field on or off. WPClever also documents that it plays nicely with their other WPC plugins (Smart Wishlist, Smart Compare, Buy Now Button, Product Quantity), so if a store is already running one of those, the sticky bar’s button styling and behavior should line up automatically rather than needing separate customization.
The honest tradeoff is that “does one thing for free” means there isn’t much dial-turning available. There’s no color picker, no per-product or per-category exclusion rule, and no analytics on how often the bar gets clicked. If a store needs the bar hidden on a handful of specific products, or wants it recolored to match a specific brand palette down to the hex code, this plugin doesn’t offer a lever for that; it ships one sensible default look and a placement choice, nothing more.
Simple Sticky Add To Cart For WooCommerce
Simple Sticky Add To Cart For WooCommerce, from Solbox, is the styling-heavy option of the three. The free tier alone lets you turn the bar on or off separately for desktop, tablet, and mobile, pick its position, and set custom colors for the background, the button, the button’s hover state, the stock label, and the star rating, plus toggle the product image and the price range shown on variable products. That last detail matters for stores selling sized or colored variants: the free version shows a price range in the sticky bar rather than forcing the shopper to reopen the full variation selector.
- Price: Free, Pro from $39/year (single site)
- Requires: WordPress 5.0+, PHP 7.0+

Installing it is the standard drop-in: extract the plugin zip into /wp-content/plugins/ or upload it through Plugins > Add New > Upload Plugin, then activate it from the Plugins list. From there its settings screen exposes the desktop/tablet/mobile toggles and the full color set mentioned above, and the vendor’s site links to a live demo built specifically around a variable product (a hoodie with size and color options) so you can see how the bar behaves before committing to it on your own store.
The plainly stated catch is that Ajax add-to-cart sits behind the $39/year Pro upgrade, alongside per-product and per-category hiding rules, click analytics, and a redirect-after-add option. On the free tier, clicking the sticky button still triggers WooCommerce’s normal add-to-cart request rather than the smoother same-page Ajax version, which on some themes means a brief page reload instead of an instant cart update. For a store that already has Ajax add-to-cart working everywhere else on the page, that inconsistency is worth testing before launch.
Sticky Product Add to Cart and Checkout Bar
Sticky Product Add to Cart and Checkout Bar, built by OneTeamSoftware, is the only plugin here that doesn’t stop at the product page. It shows the same kind of sticky bar with a thumbnail, title, rating, and Add to Cart button while browsing a product, but it also adds a sticky Checkout button to the cart page and a sticky Pay Now button to the checkout page, so the “always-visible action button” idea carries through the whole path to a completed order instead of ending once the item is in the cart.
- Price: Free, Pro from $20/year (single domain)
- Requires: WordPress 5.6+, PHP 7.3+
- Last updated: May 26, 2025
Setup is genuinely specific to this plugin rather than a generic zip-and-activate: after installing it, go to WooCommerce > Settings, open the “Sticky Product Bar” tab, work through its options (which product information to show, whether it appears for out-of-stock products, whether the button switches to “Proceed to Checkout” once an item’s already in the cart), check the Enable box, and save. It also supports right-to-left languages and lets you define custom CSS selectors for stores whose theme has renamed the standard price and quantity elements, which is a genuinely useful escape hatch for non-default themes that the other two plugins don’t mention offering.
The limitation to state plainly: this one hasn’t shipped an update since May 2025, over a year ago as of this writing, and its readme lists compatibility tested only up to WordPress 6.8, while the other two plugins in this comparison are both tested against the 7.1 line. That doesn’t mean it’s broken today, but a store relying on cart-and-checkout-wide sticky bars should budget time to verify it against a current WordPress and WooCommerce version before leaning on it long-term, and shouldn’t assume the vendor will patch a compatibility issue quickly if one shows up.
How to pick
- If the only goal is “keep the add to cart button visible while scrolling” and nothing else, and you’d rather not think about it again, use WPC Sticky Add To Cart. It’s free with no upgrade prompts and covers the basic case cleanly.
- If you sell variable products (sizes, colors, bundles) and want the bar’s colors and behavior matched precisely to your theme, or you eventually want per-product exclusion rules and Ajax add-to-cart, use Simple Sticky Add To Cart For WooCommerce and budget for the $39/year Pro tier once you outgrow the free settings.
- If your biggest drop-off isn’t add-to-cart but the walk from cart to checkout to payment, and you want a consistent sticky action button the whole way, Sticky Product Add to Cart and Checkout Bar is built for exactly that case, just verify it against your current WordPress and WooCommerce version first given its update history.
- If none of the three fit because you need the bar tied into custom pricing logic, a bundle builder, or a checkout flow none of these plugins anticipated, that’s a case for a custom plugin build instead of stretching an off-the-shelf one.
Frequently asked questions
Does a sticky add to cart bar actually improve WooCommerce conversions?
It removes one specific piece of friction: a shopper who’s read most of the way down a long product page no longer has to scroll back up to find the buy button. Whether that moves your conversion rate depends on how long your product pages actually are; a short product page with the button already visible above the fold won’t see much benefit from adding one.
Will these plugins work with variable products that have size or color dropdowns?
Yes, though behavior differs slightly. Simple Sticky Add To Cart For WooCommerce explicitly shows a price range for variable products directly in the bar, and WPC Sticky Add To Cart says it works with decimal step, min/max, and default quantity values. In practice, most sticky bars for variable products either show a price range or scroll the shopper back to the main selector to actually choose a variation before adding to cart.
Will adding a sticky bar slow down my product pages?
All three are lightweight, single-purpose plugins rather than full page builders, so the added weight is small compared to a theme or a multi-feature suite plugin. If page speed is already tight, test with a tool like PageSpeed Insights before and after activation rather than assuming either way.
Can I show the sticky bar only on mobile or only on desktop?
Simple Sticky Add To Cart For WooCommerce has that built into its free tier, with separate enable/disable toggles for desktop, tablet, and mobile. WPC Sticky Add To Cart and Sticky Product Add to Cart and Checkout Bar don’t call out device-specific toggles the same way in their documented settings.
Do any of these three replace a full WooCommerce cart drawer or mini-cart plugin?
No. A sticky add to cart bar and a sliding side-cart (sometimes marketed as a “floating cart”) are different features that get confused because both use the word “floating” or “sticky” in their names. A sticky bar keeps the buy button visible on the current page; a side cart opens a panel showing what’s already in the cart. None of the three plugins here are side-cart tools.
Whichever of these fits your store, a sticky add to cart bar is a small, single-purpose fix, and it pairs well with other product-page work like a size chart for variable products or a quick view plugin on category pages. If you’re weighing several small WooCommerce product-page plugins against having something built to spec, our WooCommerce development team can tell you honestly which way makes more sense for a store your size, and we cover more of this kind of ecommerce plugin decision in our other posts.
