For the Standard Plan to say it offers Service Management then there should be the capability of at least 1 sandbox for a chargeable instance.

I would ask that Atlassian review their policy on this urgently.

Free - No Sandbox

Standard - 1 sandbox per instance
Option for additional sandboxes at a price  (rolling monthly with Opt out any time per sandbox) 

Premium - Unlimited sandboxes.
or 10 sandboxes with option of additional sandboxes and a price (rolling monthly with Opt out any time per sandbox) 

• Benefits:
  • can you safely develop and test new features properly.
  • Allows for larger Options testing for Projects
  • Multiple diverse Projects being tested at the same time
  • More Profit for Atlassian !!!
  • Scalability for Admins
  • Less risk to deployment of new features in the Service management too for standard tier users
  • Actual service management function in the standard tier !!
