How does Autoship compare with Woo Subscriptions?
On a high level, we think the main distinction should be drawn between whether or not your business markets Subscription plans or Replenishment. Subscriptions rely on the creation and marketing of Subscription plans, while Autoship offers replenishment for any product.
For example, if you're marketing a subscription box that costs the same price every month and you don't expect your customers' plans or needs to change, then Subscriptions should be a close fit to your marketing.
On the other hand, if you're looking to enable recurring orders for products that customers can change according to their schedules and needs, then Autoship is the best fit.
