The simplest solution is to send a monthly invoice like a mailed utility bill.
It might be neat to create or extend a bitcoin client that accepts invoices/requests that you can approve like many bank's bill pay services, but without the middle man. You would need to figure out how to prevent getting spammed with requests.
It probably isn't worth the effort though, because I'd bet that one day someone will just make create a credit card based on bitcoin just as they have for most other currencies (I don't think one exists yet).
