We saw the funnelkit option and decided to give it a try instead. Its WAY BETTER. It works as intended (no longer experiencing the weird issues we were with the previous plugin), was super simple to set up, the Apply/Google pay integration is super clean (and provides some great options where to show these buttons) and the support team, when needed, has been exceptional. HIGHLY RECOMMENDED for any woocommerce store using square for payment processing. ![](https://secure.gravatar.com/avatar/ed3e01112b2c6f13df987c193443b0ea26ea1e66e11ed79b0d264c0a446c8fe6? s=60&d=retro&r=g) ### 󠀁[Finally a Square plugin that actually works](https://wordpress.org/support/topic/finally-a-square-plugin-that-actually-works/)󠁿 [brolo](https://profiles.wordpress.org/brolo/) August 28, 2025 The old WooCommerce Square plugin is absolute trash. I’ve been wrestling with it for years—broken features, useless support, and Apple Pay/Google Pay that never worked no matter how many times we “verified the domain” exactly like their docs said. Then FunnelKit dropped this Square plugin and holy hell—it’s night and day. It just works. Apple Pay and Google Pay were live in 10 seconds flat. One-click options at the top, cleaner interface, ability to tweak separator text, better UI… all the little details the old WooCommerce Square Plugin ignored for years, FunnelKit nailed in version one. On top of that, their support team is fast and actually fixes problems. WooCommerce’s Square team ghosted us for three years. FunnelKit? They reply, they patch, they improve. Period. We’ve trusted FunnelKit for years with their other plugins and they’ve always delivered. This Square plugin fits perfectly into their ecosystem. For the first time in three years, I can honestly say my checkout looks good, works flawlessly, and gives customers modern options like Apple Pay and Google Pay. If you’ve been banging your head against WooCommerce’s Square disaster, stop wasting your time. FunnelKit’s version is the real deal.
