Integrate Square Gateway on WordPress

I’m ready to start taking payments on my WordPress site and already have an active Square account waiting to be connected. I need someone who knows Square’s APIs and the WordPress ecosystem inside-out to wire everything up, verify it works, and leave me with a clean, documented setup I can maintain.

Here’s exactly what I’m after:
• Install and configure the most appropriate Square payment gateway solution for WordPress (whether that’s the official Square for WooCommerce plugin, a custom API integration, or another well-supported option).
• Securely add my Square credentials, run test (sandbox) transactions, then switch to live mode once we’re sure everything clears.
• Style the checkout or payment form so it feels seamless with my current theme.
• Provide a short hand-off guide so I know where to find keys, adjust settings, and review transactions from the WordPress admin and Square dashboard.

Success means a visitor can land on my site, complete a purchase or payment in one smooth flow, and see the charge appear instantly in my Square account—with no console errors, no template clashes, and SSL enforced at every step. If you’ve done this before and can turn it around quickly, let’s chat.
