5. Lock up every sale:

Giving a follow-through never means to disturb your customers whenever you need to close the sale. Here, you can inform them about the arrivals of new products. A great customer-service is the best way to treat your customers well. You can make use of the thank you notes to start the communication. Pay the services before being asked. Even you can build the right relationship on the mistake you did by swiftly reacting and making a right decision.  Once you close the sale, ask your customers that why did they choose to buy from you. If you are answered, they probably must have reinforced the trust in you.
