Need a good name to call this but basically the concept is….
User signs up for thing, gives email address, zapier action can fire after user sign up.
Invoice presented to user with a price that increases as time goes by.
Free trial offer. Sign up for 12 month free trial, fire zap to create users accounts. User can go to invoice every day and see how much time he has left with the option to upgrade now for a discount.
Price increases every day by x amount.
We could try Ascending Trial Invoice… or, INVOICE (Sliding Discount Options)… or, (12 Month Free w/ Delayed Savings Options)
