Hey Product Hunt! 👋

I'm a solo developer from Morocco 🇲🇦, and I'm excited to share GPCB Pay, a project I've been building for quite some time.

It actually started with a simple idea: bringing PayPal card payments into WooCommerce.

But haha, I quickly realized the checkout interface was the easy part. 😅

The real challenge was what happens behind the scenes.

What if PayPal approves a payment but the capture doesn't complete? What if the network disconnects? Or the same request gets retried?

I didn't want WooCommerce marking orders as paid without a verified capture, or retries accidentally charging customers twice.

So I ended up building three connected systems:

💳 A lightweight WooCommerce plugin.

⚙️ A merchant dashboard for store onboarding and PayPal connections.

🔐 A private SaaS Payment Core with server-verified captures, idempotency, and payment recovery safeguards.

GPCB Pay supports Guest Card and Advanced Card experiences, depending on PayPal merchant eligibility.

I've tested the payment flows, recorded a complete setup tutorial, and I'm now working on getting the product into the hands of real WooCommerce merchants.

This is my first payment SaaS, and building it solo has taught me a lot haha.

I'd really appreciate feedback from other founders, developers, and store owners.

If you were launching GPCB Pay, would you focus first on WooCommerce agencies or individual store owners?

And what would you improve in a payment integration like this?

Thanks for checking out my project! 🙌
