A canvasser is a salesperson who goes door-to-door to sell or present information on a product or service. Like other cold-call sales jobs, a canvasser will present the product, make a sales pitch, and offer additional upsells. Their duties may include selling goods, gathering information on leads, and securing commitments from buyers. They report back to a home base or headquarters and will revisit homes of potential customers who did not answer the first time or expressed an interest in a return visit. Canvassers may also be used to promote a political candidate, cause, or party.
