OK, well as a rule of thumb most companies that I've worked with in the SAAS space try very hard to keep all customers on the same codebase by building extensible "modules" that can just be added togheter in order to offer the functionality the customer is paying for.

Each customer have their own database containing thier data and settings related to their setup, the "application" is just running in a docker containers in Kubernetes.
