Visitors are important for the growth and survival of BNI chapters. Bringing visitors provides opportunities to generate referrals, even if the visitors don't join. Members should invite people who are looking for more business and live close to the meeting venue. When inviting visitors, members should ask open-ended questions to spark discussion about business needs and availability without overly explaining BNI. Good sources for finding visitors include local advertising contacts, business acquaintances, and people who cold call for sales. The key is to simply invite people to observe a meeting to see the business networking opportunities.
