This stage is much less manual and if needed, fully automated.
All Accounts or Contacts will automatically move on from a stage to another, without any human interactions.
First month = onboarding
Month 2 and 3 = adoption (usually it's commonly considered that the first 3 months are the adoption period)
Month 4 to 9 = expansion, when your Account is growing and has to perceive as much value as possible from your product.
Month 9 to 12 = renewal period, when all your efforts have to focus on the validating the renewal of your Account for a new subscription
More than 12 until next renewal date - 3 months = expansion
➕ Upside: ideal in term of scalability, fits perfectly for massive client portfolios
➖ Downside: less control of your Accounts journey (ex: an account can move to Adoption even though is not full onboarded)
