We use Story Points for estimating complexity of User Stories.
But we bill hours to the client.
This is very first Scrum project in this company and we don't have enough data to proceed with price per sprint.

I was asked by Executives to also track all Scrum ceremonies in JIRA.
In my whole Scrum career I have never encountered such a thing. My "danger alarm" is ringing like hell.
I can see their point. As the project is running in Scrum, we should bill also "Scrum time" to the client. The very same way, we bill Project Manager time in Waterfall projects.

I know, that "normally" we should bill sprints, where ceremonies are included, but we are not ther yet. I try to be openminded, I haven't found anything in the Scrum Guide against tracking Scrum time.
I can create "Task" in each sprint, where we will clock time.

Is this technique strictly against Scrum ?
