Offline payment automation

Good morning, I would need to allow users to use offline payment with upload of the payment receipt, e.g. bank transfer, or the bank's transition code, e.g. CRO. Would this be possible?

Thank you
 

Hello

It is not really possible. However, you might want to create a File custom field to allow users to upload that receipt while subscribing for the plan. That might work (the field should be optional so that in case users use other payment method, they are not forced to upload the file)
