Which plan to pickStart on Free to check the data covers your market. Basic suits one person prospecting; Professional is worth it if you also call prospects or want AI scoring. Monthly billing costs noticeably more than the yearly prices shown.Support Team only makes sense for email-only teams. Most businesses wanting AI and live chat should trial Suite Professional (the trial includes Copilot), then work out how many AI resolutions they will use, because extra resolutions at about $2 each can cost more than the seats.
