Run the Business
The parts of freelancing that aren't the work and aren't the money: remembering to follow up on the enquiry from three weeks ago, knowing which proposals are still live, keeping project scope from quietly doubling.
The client pipeline gives you one board where every lead has a status and a next action, so nothing dies from being forgotten. The project tracker keeps deliverables, deadlines, and scope changes in one dated record you can point a client at when they ask for the fourth round of revisions — and totals up what unbilled extra work cost you over a year.
