An Agent is someone who works on their own to sell things. They used to mostly work outside, but now they
can do their job from home using the internet. Agents make money by selling things. They aren't employees
of the companies they work with; it's more like they're business partners. Unlike shops that buy and keep products
to sell, sales agents usually don't buy products themselves. They talk to customers and make deals, then pass the
information to the company that delivers the products or services. Sales agents pay for their everyday things like
travel and other expenses. They can earn money through commissions, retainers, and sometimes even a service
fee for bringing in new business for the company.
