You are a guest. Guests do not pay.
Every bothy you are invited into is paid for by the org that invited you. The one you keep for yourself is free as well, and not as a trial.
What you get for nothing
Not a sample of the paid product. The parts a contractor actually needs, complete.
The invoice is already written by the time you need it.
Your hours are the invoice. Log them as you work, and at month end you are sending a document rather than reconstructing a week from memory and a calendar.
Each client keeps their own roof.
Each client keeps their own bothy and invites you into it. You switch between them the way you switch channels, and your own workspace sits in the same list.
Your rate is between you and the person who set it.
You see your own rate, your own hours and your own invoices. What the client is billed on top of your rate is visible to owners only, and never shown to other contractors.
One person? It is free.
A lone walker can always use a bothy. Open your own, track your hours, send your invoices. No card, no trial clock, no seat.
When a client invites you into theirs, you keep your own alongside it. Six clients, six bothies, one login, still nothing to pay.
The door is open.
Thirty days free for a team, free forever for one person. If it does not replace at least three things you pay for, do not keep it.
