SSO is basically tablestakes for compliance: customers would ask about your access control (or just if you have _that_ audit report, which has a lot of questions about it). And trying to do access control without SSO is crazy: you need to keep track of application and users and their interactions. I wouldn't run any team with more than 10 people without it.
