Simple question

[rvd420]

Hey,
I was asked by a friend to check into something they would like to add to their store. They have 3 stores and would like to have realtime access to the other stores inventory and such but do not know how to go about doing so. Is there a resource that could help them that gives an ideal of what is needed or someone have advice to give them?

Thanks in advance
