I am starting a lead generation business and making money through referral traffic to local businesses. I take a percentage of the sale of leads I refer to the business. Let's say for example I am working with a dentist. I have a 1-800 cloud number forwarded to his business number. I assume that the honor system will work and he or she will pay up when I generate those leads. However, are there any alternative tracking methods that you can think of? My cloud phone system records calls so I will be listening to see how they go however I don't feel like having to investigate to get my portion!
