For communication can be used by sales agents, managers, working for phone or e-mail. To collect database use free activities in which customers fill out a questionnaire to obtain important information. Warn that will periodically connect, but do it only about that interested in people.
Receive from customer pre-orders before negotiate with suppliers. Pre-order is not associated with the payment of money, but it is important for prospective buyer took the initiative and declared its intention to buy the product/service. To receive pre-orders direct customer base offer. All participants put in a separate list and continue to work only with him. So will save other people from the database from unnecessary messages. They won't complain that you are sending unwanted advertising and will not refuse cooperation in the future.
Take the goods for realization. Agree with the vendor that will return the unsold goods. You can not guarantee that all the people included in the list of pre-order will pay for the purchase. Therefore, the necessary agreement with the supplier. The talks will inform that work with regular customers, and the product will not lie around somewhere in the warehouse: everything will be decided in the next few days.
Make the customers a particular offer. Let, the number of items is limited and the timing of payment is possible only within a specified period of time. Can add to purchase enjoyable small things to encourage customers to instant decision. Think about the amount of profit and make customers the delivery, special packaging or gift.
Return to vendor unsold copies. Do it quickly. Don't hold your goods in the warehouse.
Keep stats to know how much profit on average brings to every customer. This will allow you to plan advertising investments in the expansion of the customer base.
