By default ShowHouse is set up with a single (primary) branch. Even if you don't have a physical head office, the software considers the main address provided during setup as being the primary office.
Many agencies have offices at more than one location. You can set up a branch for each location via Account Settings > Agency Settings > Branches.
There is an additional month charge for each additional agency branch configured within ShowHouse. The initial branch which is set up when your account is created does not incur any charge, just the second and any further branches.
Charges for additional branches can be found on the main ShowHouse website's pricing page.
In order to add additional branches you first must have the required number of branches active on your ShowHouse subscription. If not, you will be prompted to upgrade your subscription to add an additional branch before you can enter the new branch details.
