Fix Stripe Payment Integration Issue on SaaS Fintech Platform

We need a developer to resolve a Stripe payment integration issue on our SaaS fintech platform. The work includes identifying the root cause, fixing the payment flow, and ensuring transactions complete successfully. You will also review the current setup, test the solution thoroughly, and help improve reliability for future payments. This is a short-term project for someone who can work independently, communicate clearly, and deliver a stable fix quickly.
