Hi guys, a friend of mine is a photographer. He wants me to pimp his skills online so he can get sales with local clients. He's agreed to pay me a certain percentage of every client he closes the deal with. But I cant figure out how I'm going to track his sales? Sure I can track leads! With a Google voice number, I can track the number of calls etc. but that would be just a lead. Its his phone, so a client finds him online, calls him up, he'd answer the client, meet up with the client, offer upsale, close the sale. But I cant find a way to track the sales, not just the leads, since I'll be getting paid for the percentage of the sales only. He owns the website. It says his name in the url too. He makes clients sign an agreement, but how do I know if he's going to tell me about ALL of his sales and pay me for them? We tried to come up with a solution so the sales are transparent to me, but couldn't. Basically every solution we could come up with had a loophole and I'm the one at risk. I'd appreciate any advice.
