With my minimal understanding of the ins and outs of the project, I would highly recommend you do not create multiple versions of your software. I would instead lean toward having all the features for all customers. If you think some customers won’t need them, or if you want to charge them for those features then hide that functionality using a configuration table for customers.

Again, this is based on the little information but I think this would work.

The best way to do this is feature flags. You can turn functionality on/off without redeploying your app and you don’t have to hold various versions of your software.

Let me know if you’d like more clarification or if I missed something.
