In affiliate marketing context, batch process transactions is when a merchant does not pass in real time each transaction or conversion referred by an affiliate to the affiliate network platform for being displayed in the affiliate’s web interface.
Instead, the merchant processes and verifies transactions by batch before sending orders to the affiliate platform. Batch of transactions can be sent every day or several times a day.
