This discrepancy was due to the fact that Konark couldnt give us the discount for shortage of the food ( Usli Channa ) for 275 people and awaiting for approval from their management.
I followed up with them repeatedly and got the discount from the top management of konark
hence the delay,
If i had given up then we would have lost this money and hope this is usefull for the school :-)
This is a common delay in food industry, of the billing for large scale volume
