This question already has an answer here:
Does anybody know why - historically, etymologically or logically - one can use polite forms (e.g. -ます) in causal subordinate clauses before から, while one must use the plain form before ので?
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
As you can see in the linked post, and Chocolate and Bjorn's comment - you totally can use ので and から after the ~ます form of a verb.
When I lived in Japan I heard people say, 行きますから and 行きますので
If you want to know the difference, you can check out This website ~ Kara vs Node, it does a great job of explaining. But a basic difference is that から is less formal than ので.
