The online project management and project collaboration service Zoho Projects becomes interesting for software companies, as it gets quite functional bug tracker. It allows you to add bugs, assign owners, collaborate on bugs and control their statuses. There are flexible options for email-notifications of various actions in the system. You can set the individual processes and rules for the automation of certain operations - for example, when issue status changed, it can automatically be assigned to another owner (for example, to tester) and change its priority. Unfortunately, the bug tracker is included only in the most expensive Zoho Projects subscription plan ($ 699 per year for 30 GB and unlimited number of users). But for these money you get the most featured online project management system on the market, which includes: project plan, calendar, tasks, file sharing, forum, chat, wiki, time tracker, billing, bug tracker, reports. In addition, Zoho Projects is seamlessly integrates with other Zoho services and Google Apps.
