Hello,
Add a credit card to work as Withholding Tax in the amount.
The value of Withholding Tax has to be sent from a Webservice provided by us.
The detail of Withholding Tax has to be saved in SBO before sending to the POS, so that when we get the payment we can make a new journal entry for reclassification the accounts and the Withholding Tax codes.
Kind regards,
Cornelius
