Try this' @FrozenjaZzBeats' , When someone states they are interested in your track for exclusive rights, give them a time frame. Learning to "close" sales is kind of tough. But you have to show some sort of urgency as well, because you don't want to leave these types of emails "open". "Open" meaning that the client as the power to come whenever they want expecting the same deal.
So for example, Client comes to you stating that "I want your beat and I'll pay you $200 exclusive for it", you say "That sounds great! Can I send you the invoice now or the instant payment download link?" Customer: "Not right now, I have to get some money together",
You: "That's no problem, I will sell you the beat for $180 if you can pay by this date.....I'll also throw in a discount for mixing & mastering .... only available if you purchase by this date. Please let me know if this works for you"
Customer: " That sounds great! I'll keep in touch.
Now, when the date comes two things can happen, The client can pay you what is owed, or you can reach out to the client to remind them. Either or is better than having the client get all the power of when they want to purchase. They clearly are interested and clearly can get some money, thus why they asked.
So this may help for future sales.
