Whilst we understand the potential benefits in being able to provide access to your project management tool like Trello, Teamwork, Podio etc.. this isn't something we currently support or plan to support.
Our clients like the ease of communication and speed of implementation that we can provide through our Support Platform (via Email and our Client Portal).
This support platform and the efficiencies it provides is a big contributor in what allows us to offer Unlimited Tasks.
If you are using an external project management tool, we recommend setting up the individual tasks inside your project management tool as the exact same tasks you request to us.
This way when one task is resolved on our end, you can tick it off in your project management tool.
