How to support multiple physcial work locations

How to set up one instance of Cetec to support 3 different physical locations for our company?(we would add more users)

I talked to support about this at the palooza and they said this was the best way to go about it, as we would each have our own warehouse location and GL account. Just looking for steps to implement this now. (or is it as simple as just creating new warehouse location and gl account?)

THANKS!
