[OJS] OJS3 Readership, Buy single article fee

How a single article buys or readership fee works with OJS with manual payment. I have been able to send Manual Payment Notification for a single article but where these notifications go and how can we approve single article purchase manual fee?

Hi @esciencepress,

Please see Subscriptions in Learning OJS as a starting point.

Kind Regards,
