How does PieSync calculate the total contact count?
To calculate the total contact count , we add up the unique contacts in sync PER connection. If the contact is present in two connections, we count that contact twice as these are two separate syncs we perform (we scan every 2-3 minutes) to keep that contact in sync continuously between the two particular apps in each connection.
Below you find an example: this user has the same ConnectWise Manage synced to 2 different apps. Some contacts might be syncing in these 2 connections. There's a 3rd connection too. We sum up all the contacts in each individual connection to get the total contact count of 129.
You can control the number of contacts kept in sync by applying filters.
