Service area businesses usually don’t have a physical office location that the public can visit in order to do business. These businesses will travel to their customers to perform work. For example, a plumber may use his home address for his business but they never have any customers come to their home. Instead, they drive to their customer’s home to work on their plumbing issues. Other examples include locksmiths, maid services, limousine services, mobile notaries, carpet cleaners, freelancers, etc.
A service area business may even have a physical office location that customers can visit. But when they perform work, they will still need to travel to their customer’s location to carry out their work. For example, an HVAC company that has an office but still travels to their customer to fix their AC.
