    I am encountering a critical technical issue with my CS-Cart Razorpay Payment gateway. I recently discovered that the tax amount is not adding correctly to payment transactions. While I am not aware of any existing system logs, it is necessary to generate these logs to better understand the problem and potential solutions. It is likely that both system-level and application-level logs will be needed to pinpoint the cause of the issue. I am now seeking a Freelancer to quickly address this issue and ensure that payments with tax properly added are possible. Testing website link Payment Gateway Razorpay

    Modify existing Apps and publish them 13 ώρες left

    We bought a packaging of 2 Apps developed in Flutter (User and Handyman) and a Dashboard in Laravel. We need to make the following customizations: 1.
