Quickbill Embedded Payment

Some clients already had their own invoicing and only wanted the payment part. So I built a small checkout they could embed: the customer picks a method, clears 3D Secure when needed, and lands on a clear status screen. No Quickbill account required.

I kept it light on purpose. Vite instead of Next.js, and only the components it needed from Quickbill UI. I also wrote the integration docs and worked directly with client engineers while they plugged it in.
