We currently have 2 forms of licenses, for different kinds of customers:
An individual license is for private customers that want to use their business email address in Thunderbird and costs 10 Euro per year. This provides a license to use ExQuilla with one Exchange email address. You may use this license on multiple computers as long as you use the same, single Exchange email addresses on all of the computers. Single licenses are always billed to the private individual and to their private email address and are not suitable for companies.
For companies, we have domain licenses which cost 8 Eur per user per year, with a minimum of 10 users, without taxes. With domain licenses, you get an invoice on your company address.
