I am looking for a modification of payment api that permit manual payment approved by admin. User pays in various ways, send me confirmation of payment and I validate manually his subscription.
I have a small professional community so total number cannot go above 10k users and some of them are not familiar with electronic payment. They will send money by post, direct payment in bank account (or even pay me cash when we meet

) and I want to take advantage of the subscription system build in VB (reminders for end of subscription, period subscripted) so I don't need to make a separate group and write down each username , and period of subscription.
My alternative for the moment is to make a group user request to join and I approve after receiving the confirmation of payment. This way I need to keep manual track of each user time of subscription ending and name.
I have no coding knowledge but willing to learn or appreciate a helping hand.
Maybe I am lucky and there is a setting I don't know in vb allowing me to do this !
PS I will like to have this additional to electronic payment (for users able to pay this way)
after I manage to integrate my local card processor using this tutorial I am thankful for
Edit:
Found by accident a possible solution. In Subscription management make a valid payed subscription (even if no bank set) and manually add users from drop down menu in Subscription manager page from Admin CP. Hope is useful for some.
