Encore lets you raise the money for a record, a merch run or a tour before you make it. You set a goal and an end date. Fans pick a tier and save a card. Nobody is charged unless you reach the goal by the end date.
There are five types: Digital, Single, Album, Merch and Tour. A tier can hold more than one item, so a bundle is a tier with several things in it.
Encore runs on your own Stripe account and the money goes straight to you. It needs a paid Pro or Lifetime plan. The 7-day trial doesn't include it.
