Just because you paid for the lead, it doesn’t mean that you should get emotionally attached to each one. Buying leads is, and always will be, a sorting process to find your next business partners. If you are terrible at the phone, either, buy MLM leads or get a job at a telemarketing company. Gaining experience on the phone is worth its weight in gold. Every big recruiter or enroller is good on the phone. Most of them used to be terrible but experience made them better.
Develop a referral program. Just like in other businesses, people who are referred by others are easier to convert to a sale than people who weren't, because they're usually coming to you with some interest in buying. Many people you talk to won't be interested in buying right away, but they might know people who are. Happy customers may want to share your product or business. You can develop a referral program to give people incentive to refer others to you. For example, you can give them a 10 percent discount on their next purchase for every new customer they refer.
