This is the latest version of an email which I send periodically, offering customers the opportunity to pre-pay for SaaS in return for a discount. The benefits to the SaaS company are better cash flow and reduced churn rate. The benefits to the customer are, well, in the email. This genre of email has produced hundreds of thousands of dollars in pre-pays for some companies I work with, and it rarely requires any more work than this example.
I've put $79 is as a placeholder for the cost of the user's plan. We calculate that for each account, naturally, along with the billing contact's name.
