There are a few options available to you, such as making just one site able to fulfill orders, setting a default site (while still allowing both to fulfill orders) or manually moving individual orders. How to set which site will be used for which customers or handle "consignment"/"sale or return" stock should explain the options and how to choose the one that works best for you, but please do let us know if you have any questions on this.
