Every project, client and internal, on one board
Delivery work, retainers, and your own internal roadmap run in the same system, tied to the client record and the contract that pays for them.

An illustration of the OS3 task board: a client and project rail beside four columns — to do, in progress, blocked and done — each holding tasks with the project they belong to and the person leading them.
Boards, lists, timelines
Switch views without rebuilding the project. Dependencies and milestones carry across all of them.
Templates per work type
Spin up a retainer month, a sprint, or an onboarding from a template that already has the tasks and owners.
Capacity you can see
Assignment shows who is already committed, so plans account for the work people actually have.
Structure
Tasks that know who they bill to
Every task inherits its client, contract, and rate from the project above it. When someone logs time against it, billing is already correct. No mapping exercise at month end.
Delivery
Client work and internal work stop competing invisibly
Internal initiatives sit in the same capacity model as billable delivery. When the new-business push eats a designer's week, the project plan shows it before the deadline does.
PM agent
The agent runs the standup you keep skipping
It watches dependencies, due dates, and activity, and moves first instead of waiting for a status meeting.
