No. Flippa is a marketplace for buying and selling websites and domain names outright.
Flippa can't be used to sell:
temporary, non-exclusive or leased licenses to property
access to services
memberships or subscriptions
discounts that apply to any of the above
Flippa accepts that accounts -- such as an associated Twitter account -- may be included as part of a site or business sale or auction.
If you are selling a domain name, you must give the buyer full ownership and control of the domain name, including the ability to transfer it to the registrar of their choice.
