I am a civil Engineer consultant. On an item for example Rs.100, I am adding 4%WCT ie., Rs.4 and I am certifying the contractor bill for Rs.100.00 + Rs.4.00 = Total Rs.104.00. But my client is deducting 4% on Rs.104.00 ie., Rs. 4.16. So, finally contractor is losing Rs. 0.16 on Rs. 100 which amounts to lakhs on the project value. Can you please guide me on this?
