As of this writing, the average salary for a CSM can range from 60k-200k yearly according to BuiltIn.com. Other benefits include:

Remote Work - CSMs are rarely required to report to an office as their job function doesn’t normally require it (this varies from company to company)

Work Related Travel - While this can go either way, those who like to travel to see customers will really enjoy this benefit

Sponsored Company Conferences - Meet clients at your company’s conference and be among professionals who are just like you
