BugTracker.NET提供了1和2。关于3，它允许您通过创建自己的报告来扩展它。你只需编写一些 SQL 即可。它在Windows Server 2003 上运行。它不需要XAMPP。它将使用免费的 Microsoft 工具、IIS、.NET 和 SQL Server Express。

Take a look at Jira , made by Atlassian. The billing component can be managed by doing a monthly search I suspect. The private comments can be handled via what they refer to as notifications schemes.

看一下 Jira ，由 Atlassian 制作。我怀疑可以通过每月搜索来管理计费部分。私人评论可以通过他们所谓的通知方案来处理。
