Door-to-door sales is one of the oldest direct selling methods. Salespeople visit potential customers at their homes or offices to demonstrate products and close sales.
It's particularly effective when products need demonstration — vacuum cleaners, solar panels, or home security systems. The personal interaction builds trust and allows real-time objection handling.
While declining in the digital age, door-to-door sales remains effective in certain industries, especially where personal relationships and trust are essential. Many successful companies, including Kirby and Vivint, still rely on this approach.
