Intermediation is the process of linking an account or customer record belonging to an individual or organisation to a client list of a business intermediary (like a tax agent, bookkeeper or payroll bureau) so the intermediary can act on their behalf.

About the intermediation service

The intermediation service is a SOAP web service that enables intermediaries to:

  • link, delink or update the intermediary client list to their clients' accounts or customer master
  • retrieve clients and client lists that have already been established.

Intermediaries can use this service to create and manage links from a client list to a customer master or their accounts on any tax product.
