Hello all!
Does anyone have experience selling a customer list to another business ?

To give some context, I cold called a business owner who is shutting down his business because it's a side hustle he started a few years ago because of the pandemic and being laid off from a job. His customers are mostly commercial contacts like buildings/hospitals and I said I could help him get something for his list.

I spoke to another company who would be interested in this individual's customer list but wants to see the value of the customer list before deciding on what the commission would be between me and the side hustle owner. What's the best way to go about this? I don't think it's going to make sense to see someone's customer list but there has to be in it for both parties.

Does it make sense to shop the list around?

any insights would be helpful.

Thank you!
