To enable the Payment Module, click on the link listed under Management Pages.
You can enable the Payments Module by clicking the box under General Options. You can also choose your currency here. You should ensure that the currency you select here matches up with the currency selected under Subscriptions, if the subscriptions component is also being used.
Further down the page, you can enable and customize author fees for article submission, fast-track peer review, and article publication. Note the Waiver Policy. If filled in, this will display along with the Submission Checklist in article Submission Step One, and in About the Journal, under Submissions.
Reader fees can also be enabled. This can be used for either subscriptions or pay-per-view.
As can general fees for association membership and/or donations can also be added. The Association Membership information will appear in About the Journal under Policies, and the Donation link will appear above the search function in the right-hand frame (it is a sidebar block that can be re-positioned -- see Journal Setup for details).
