Support of domestic supplier payments in Pounds or Euros is done through BACS and the UK Banks Clearing House system. BACS is the supported banking interface for all the major banks in the United Kingdom. The BACS version that is implemented depends upon the requirements of your bank or other service provider:

BACS V01 provides one contra record per payment.
BACS V02 allows one payment level per mapping. No contra record is written.
BACS V03 allows multiply payments per mapping. Several contra records are written.

All submission to BACS must be digitally signed by using valid PKI credentials. If the user is submitting indirectly, this becomes the responsibility of the bureau or bank.

Support of customer payments that are received electronically is through Bankers' Automated Clearing Services (BACS) and the Clearing House Automated Payment System (CHAPS), which are used by all major banks in the United Kingdom. Direct debiting with or without customer agreements is also supported.

The use of the Automated Direct Debit Instruction Service (AUDDIS) for new Direct Debit Instructions is mandatory for the submission of debit transfer to BACS.

Note: This is a manual activity that must be in place before the electronic message is deployed.

A contra record is created after every Detail record in the message.
