How to make sales on Whatsapp?

I have a lot of leads to my Instagram management on Whatsapp.
I talked with 60 people already and wasn't been able to close a single sale
Is anyone has something that can help me to close sells?
Thanks

Are you selling guitars?

Depends on what you are selling them and the cost of your service. Is it over priced ? How much is your competition offering the same service ? What irresistible value are you offering them to edge on your competition ? Etc, figure that out and you will begin to get the sales coming in
