Regulations need to be followed from both states and the federal government.
Each state can set regulations because business is happening in each state. You would also need to follow federal regulation because you are crossing state lines to conduct business.
The federal regulations are typically fewer in number and scope but would create general guidelines for running the business. Due to federal power being superior to state power, all federal regulations would take priority over the state regulations. The states could each regulate business in addition to the federal regulations. Therefore state regulations tend to be more precise.

Explanation:
In order to make business in each state, you have to follow their regulations as a requirement, since they define the specific terms and rules you have to follow in that specific state.
Since you are working in several states you also have to follow federal law, this one is not as specific, but it will also have guidelines that you will have to follow for your business, that are not in the state regulations but are also mandatory.
