It will depend on how you want to work with those clients.
With RedTrack, 2 scenarios are possible:
1. You create a separate white-labeled reporting dashboard where your clients will be able to check the reports on their offers anytime. The access level is based on their products. Nobody will see anything more than you want to show. The access is based on the products promoted. That means you can have various publishers traffic on the same offer. The clients will have only the final product click information.
2. You can share access to your account and restrict it on certain campaigns, for example. In this case, the access is based on the sources of traffic (publishers). If you want to restrict access to a particular product, this option may not work.
