Exchange Rates and Credit card charges

[Aditya]

Today Concur doesnt factor in credit card charges for transactions outside of native country. For instance Indian credit cards charge CGST and SGST on credit card transactions outside of the country. These bring effective exchange rates 4% higher than what system has. For instance if system uses 79.8 as conversion for USD to INR with credit card charges the effective exchange rate is 82.88. 

Is there anyway to circumvent this challenge - most credit card statements dont show this separately, only on the app/website at a transaction level you could see these details. For monthly statements, only the effective exchange rate which is higher is used to generate the bill/statement. The only option is adding these charges through currency conversion but its painful to add multiple entries itemised for a 2 week travel.

Any suggestions of how to circumvent the problem?

@Aditya I don't believe there is a way to circumvent this. The system reads the amount of the transaction as reported by the vendor. It is the credit card company that is adding on these taxes after the fact.
