The number of people making changes in your repositories may fluctuate month-to-month. That’s why we only bill for active contributors. An "active contributor" is defined as a committer that has authored a commit within the past 30 days inside a repo you have imported.
If you exile a committer (such as a bot), they will not be included among your "active contributors." When a developer makes commits from multiple work stations, we will automatically connect those identities such that they only count as one contributor (even if the committer may author commits from multiple email addresses).
Other enterprise software companies charge a per-user fee regardless of actual use, but we only take into account contributors who have made one or more commits to your code repository in the past 30 days. Learn more about active contributors and our billing cycle.
