Okay, This solution was useful for service sector.
In your case, If you want to pay 2,500/- as discount then you can ask him for invoice, which will be generated by him. if he issued invoice of Rs. 2,500 + GST, then you will pay that amount & avail ITC.
Reverse calculation means Rs. 2,500/- is GST included value.
