Membership of GNTX is subject to an annual membership fee and commission payments based on use. The annual fee covers account management and administration, user support and marketing activities to expand the membership to increase the scale and scope of content available, as well as the number of potential buyers. During the application process members will be required to read and sign a user agreement.

At the completion of the membership process, GNTX will invoice the member for the annual membership fee or the fee can be paid via credit card. Once the fee is received the nominated users from the member organisation will receive an invitation to login. Fees will be advised during the application process.
