Usually business-to-business marketing strategy involves a more direct channel of distribution because of the volume of each transaction and the need to relate product knowledge to the business buyers. Advertising and promotion for the business-to-business market involve more trade magazine advertising, direct sales, and trade shows. For a start-up venture attendance at a trade show can be one of the most effective means to reach many potential buyers in one location. At trade shows it is important to distribute material on the venture’s products and services and to keep a log of all interested visitors to the trade show booth Have visitors sign in or leave their business cards. From the log or business cards, a list can then be prepared and used as a prospect list for sales reps It is also important that right after the trade show, a follow-up letter be sent to all visitors thanking them for their interest and explaining how they might be contacted.
