Which plan to pickStandard covers most solo businesses. Only pay for Standard Plus if you don't already use a meeting notetaker like Fathom or Granola. Move to Teams when more than one person takes bookings.Start free, then move to Basic when you pass 250 issues. Go to Business when you want AI triage, support-tool integrations or private teams. Add AI credits only if you plan to have Linear Agent write code; top-ups start at $10.If your team already pays for Pro, try the basic AI first. Move to Business+ when you want AI search, the Slackbot agent and daily recaps, which is where the real time saving is. New teams get 50% off Pro or Business+ for 3 months if they upgrade in the first week.
