This option suits payers with more information and increased numbers of returns. This will require information to be uploaded in a CSV file format.
The gateway service is an interface that automatically submits a payer's information from their system to ours, without them needing to log in to our systems. It is an option for those with large data sets and leverages common industry and New Zealand standards.
