That's as ridiculous as not following up with your customers. Just because customers don't buy today does not mean they won't buy soon. Too many salespeople wait for the next customer to call or stop in, rather than following up on the previous customer. The worst thing is, they may very well have been able to close both customers with just a little follow up. A tracking system used in numerous home furnishings showrooms, showed that the customer who didn't buy the first day was most likely to buy from someone within 48 hours after their initial visit.
Customers are more emotional and their memories are freshest shortly after shopping.
To be able to follow up with your customers you need their full name, address and phone number. A survey card will provide you with all of the above. The card is given to the customer just before they leave without buying. A survey card can also be filled out by the salesperson when a customer does buy, so they have a means of following up, requesting referrals and notifying them of future sales. The title should be 'ABC' marketing survey or 'ABC 'advertising survey.
