This is what it looks like when I sell a website
On this photo you see the certificate/contract for likethisforever.com.
I sell my websites as unique art pieces. The collector receives a certificate, a backup disk with source files, and ownership of the domain name.
Part of the sale is still “physical”. I still print the contract on paper and I still burn a disk. But that will change, from now on it will be a digitally signed pdf certificate and I’ll email the files.
I think it’s cooler that way.
