Having a larger team doesn't have to mean giving up control. With Roles, you can specify which employees have access to view sensitive financial information, and which employees are only allowed to track time.
With Clientary, you can invite external contractors to projects. Contractors can then contribute to your projects and track time with their own account.
Your contractors will know they're working on a project for you, but they won't get access to sensitive client information.
No installation. No software to maintain. No credit card required (for free plan). Nothing to lose.
