Adding Attachments to Subscriptions

Adding Attachments to Subscriptions

Hello,

We have not used Subscriptions yet. Our annual maintenance contracts are often specialized one-off contracts with many pages and sometimes a lot of required legalese. I'd like to use Subscriptions to track these. is there any way to attach a document to a subscription so that the contract document gets emailed out along with the request for renewal payment?

As a second question, can subscriptions simply bill an account automatically each month?

Thank You
