Please boss in the house, how do I provide receipt to the buyer of my phone.
I wanted to sell my phone, I have the receipt of the phone bearing my own name,, so I don’t know how to provide new receipt to a potential buyer. Should I give him the original receipt that is with me(bearing my name) or what?

You can give him the original receipt

Then write an undertaking stating that you have transferred ownership of the phone to him

He should sign and u too
Witnesses should be there to sign too

...or do like some [dubious] sellers, approach a seller with duplicate receipt, pay him/her a token to write you a receipt. Such receipt is termed oluWole
