What if a vendor has multiple locations?

This is not a problem as the sEATz platform can adjust to your venues configuration.

With sEATz there are 3 levels of differentiation; Venues, Vendor, Sites.

We define Venues as stadium, locations, buildings, etc.. A great example is where the Philadelphia Flyers and the Philadelphia 76ers play their home games, at the Wells Fargo Center. Two teams, but on Venue. These will be unique to each partner.

Vendors can be unique to a Venue, but don't have to be. A great example of this is Chick-Fil-A at Minute Maid Park, they have multiple location where they sell their products. Chick-Fil-A also sells products at other Venues. 

Each Vendor must have at least one Site or sometimes referred to as Vendor Sites, but could have unlimited sites. Whats make each site unique is the menu. For example, The Chicago Bears have beer portables where they sell off the same menu for most of these locations. These are set up as a single Vendor with multiple Sites.
