After you submit a transaction import file, Fexco processes the transactions and calculates commission for each DCC conversion. The results are delivered as a Transaction Commission (TCOM) file, a CSV report that breaks down the commission earned on every DCC transaction.

From transaction import to commission

Transaction import and settlement are linked but separate processes. Transaction import reports what happened at the point of sale. Settlement determines how much commission each party earns from those transactions. The following steps describe how a transaction file moves through the system from submission to commission delivery.
  1. Submit a transaction file: You send a daily transaction file to Fexco via SFTP. The file contains every card transaction (both DCC and domestic) from your terminals, ATMs, or eCommerce channels. See How transaction import works for the full submission process.
  2. Fexco validates and processes the file: Fexco validates the file structure and integrity, then loads the transactions into Mercury. Accepted transactions become available for reporting in Fresh Insights.
  3. Fexco calculates commission: For each DCC transaction, Fexco calculates the commission based on the margin applied during the rate offer and the commission split configured in the merchant’s template. The commission split determines how the margin is divided between the acquirer, the merchant, and Fexco.
  4. Fexco delivers the TCOM file: Fexco generates a TCOM file and places it in the Outgoing folder on your SFTP server on an agreed schedule. The file contains one record per DCC transaction with the commission breakdown.
The following diagram shows the same flow between your system and Fexco.

Settlement types

DCC transactions settle differently depending on how the card scheme processes the currency conversion. The TCOM file includes a Currency type field that identifies which settlement path applies.
  • E2E (end-to-end): the card scheme settles the transaction in the DCC transaction currency (the cardholder’s home currency). The converted amount flows through the entire settlement chain without further conversion.
  • NE2E (non-end-to-end): the card scheme does not settle in the DCC transaction currency. The scheme applies its own exchange rate during settlement, which may differ from the DCC rate. The XML I-file can include non-end-to-end settlement data to capture the scheme’s settlement values alongside the DCC values.
The E2E or NE2E designation is determined by the card scheme and currency pair, not by your integration. The TCOM file reports which type applied to each transaction.

The TCOM file

The Transaction Commission (TCOM) file is a CSV report that Fexco delivers via SFTP. It contains one header row and one detail row per DCC transaction. The key fields for understanding commission are:
  • Gross Base Amnt and Gross FX Amnt: the transaction amounts in the base and cardholder currencies.
  • FX Rate: the exchange rate applied to the transaction.
  • Currency type: whether the transaction settled as E2E or NE2E.
  • Merchant Amnt, Acquirer Amnt, Fexco Amnt: commission amounts for each party, expressed in the settlement currency.
For the complete field list, naming convention, and record ordering, see the TCOM file format reference.

Reading commission amounts

Each commission field shows one party’s share of the DCC margin applied at the time of the rate offer. Commission amounts are expressed in the settlement currency. For example, in the following NE2E transaction, the base and settlement currency are both KWD. The purchase amount is 5.55 KWD, and the cardholder paid 71.27 [CARDHOLDER_CURRENCY] at an exchange rate of 12.8423, which includes the DCC margin. The margin on this transaction is 0.14 KWD, split between the merchant (0.03), the acquirer (0.06), and Fexco (0.05) according to the commission split configured in the merchant’s template.

TCOM delivery and SFTP setup

Fexco delivers TCOM files to the Outgoing folder on your SFTP server on an agreed schedule. The same SFTP credentials and connectivity configured during security setup are used for TCOM delivery. If no DCC transactions occurred during the commission period, Fexco still delivers a TCOM file containing only the header row.
