A Professional Services Organization (PSO) inside a software company is the team that helps customers successfully implement, configure, and get value from the software—usually in a paid, project-based way. Think of it as a strategy and technology consulting organization within the company... an implementation Geek Squad.
If the product is the what, PSO is the how.
They exist inside or alongside the Customer Team, but they are very distinct - not to be confused with Support or Customer Success.
CS & Support are relationship-based & ongoing. It behaves like a subscription.
PSO is project-based & time-bound. It behaves like a project.
In simple terms:
Why do companies create Professional Services teams?

In the journey:
Sales → PSO → Customer Success → Support
PSO is the bridge between purchase and long-term value.
They make sure the customer starts off strong so CS doesn’t inherit a mess.
