What is Plan tiers?

Plan tiers are the named steps a vendor sells its software in, from a small starter level upward. The names tell you how far you can climb and where the price jumps sit. ActiveCampaign lists Starter, Plus, Pro and Enterprise, and Airtable lists Free, Team and Business. 7C names its steps in Icelandic, running from Einfaldur up to Stor. Account Desk prices per agent each month instead, with a higher rate that adds AI and a knowledge base on your own domain. ANS sells managed work built to order rather than fixed steps.
