ComputerOpen Settings, then Team & seats, where you invite people and set a job title. Access has three levels, not two, and the job title you pick is what sets them — this page used to say it did not, and that was wrong.
Office seats (Manager, Operations, Sales Rep) reach everything operational: Home, Money, Ask Des, Get Paid, Customers, Team, Goals, Emails, Expenses, Margin and Ads. Bookkeeper is its own seat — books, billing and customers, no outbound email, no pay rates. Ten pages stay with you: Wealth, Foresight, Taxes, Businesses, The Record, Boost, Messaging, Settings, Jobs and Jobs & Ops.
Field seats (Technician, 1099 Contractor, Marketer, Partner) get their own work and nothing else: My Jobs, Schedule and Ask Des. Every money page redirects them, and Des will not give them revenue, receivables, expenses, pricing, anyone's pay or the tax position either — it answers about their jobs, schedule, materials and reminders, and says plainly that the rest is yours.
You can widen one person afterwards in Settings → Team & seats → Access & permissions.
