I have a question about offline payment

I have a question about offline payment: I need to make the subscription process automatic by having the user upload the payment slip, bank transfer or bulletin.

In practice, those users who choose offline payment, have the possibility to upload the receipt and only if the receipt is uploaded, the subscription process can proceed. I have seen that there is the possibility to create an extra field, but I do not know how to tie it to offline payment.

Thanks for your help.

Hello

Unfortunately, currently, we do not have a way to allow you to add custom fields depend on payment method

So in this case, maybe create custom fields to allow uploading files with instructions to tell users that they only need to upload the files if they are ising offline payment methods. Remember to make these fields optional (Required set to No) so that users who use other payment methods won't have to upload files
