can anyone help me how to change buyer to seller in iphone fiverr application
I’m afraid that if you only have a phone, it is not practical to try selling on Fiverr. To set up gigs and offer services of value, you would need access to a desktop or laptop computer.
If you are a seller already then on the app you will be logged in to your seller account automatically. As cyaxrex said, you need a computer to be a seller.
