For most existing businesses, there are two different types of customers: “simple” customers, who buy products for themselves, and “resellers”, who sell products to their own customers’ pool.
While the first type is often an occasional user, the reseller is a loyal, stable customer who buys multiple times over time. Resellers purchases are often crowded (tens, hundreds, thousands of units of the same product) and continuous (eg on a weekly or monthly basis): in practice, the reseller is, for the company he chooses to buy, a guarantee. These are your most important customers.
