@yogesh.gurjar Just to invite your colleagues, you do not have to purchase any license in either case:
- you are using self-managed (not .com so called SaaS).
- the number of your colleagues you want to invite to projects under your personal account is 5 or less (*).
I would not purchase a license only for that purpose. A limitation of the maximum number of total users in your personal namespace is still not fixed completely. Invite your team members to your project(s) first, and then stay until the enforcement date (2022-10-19 as of 2022-08-17).
