ProxyMesh supports sub accounts for all subscribers to the ProxyMesh 20 and 50 plans. Sub accounts are designed for companies and professionals that are using ProxyMesh on behalf of a client, and want to track bandwidth usage in order to pass on the cost. For example, suppose you're a pro at writing web crawlers or screen scrapers, and you've got one or more clients that require the kind of strong anonymity you can get with ProxyMesh. So you signup for the ProxyMesh 20 plan and create a sub account for each client. Now, instead of using your main account, you can use a sub account for each separate client, and see the bandwidth used by each account. Then when the bill comes due, you can charge each client for the ProxyMesh bandwidth used by their sub account. All the bandwidth tracking information you need to do this is available in your ProxyMesh account dashboard.
