We are syncing data from CS-Cart to Zoho Books.

We are in a situation where we are unable to sync a COD Surcharge option under Sales Order. CS-Cart is having the Surcharge option as shown in the attachment but unfortunately in Zoho Books->Sales ORder Option, I did not find any option where I can map this data. I have attached CS-Cart = Invoice and Zoho Books= Sales Order for the reference.

Any help/guidance in this will be really appreciated.
