SimpleSubscription

SimpleSubscription is a Shopify subscription management app for merchants, covering recurring billing, storefront subscriptions, and a customer portal. Its Subscribe & Save widget supports flexible discounts, delivery frequencies, annual billing, and Shopify native checkout. Subscribers can skip, pause, swap, or cancel subscriptions, change frequency, and update payment methods in the portal. The app retries failed payments and sends reminder emails on every plan, including Free. Shopify Sidekick AI features let merchants ask about subscription data, run subscriber actions with a confirmation step, and navigate to app editors. Migration options include Appstle, Seal, Recharge, Bold, Loop, and Skio, as well as CSV import and API migration. Plan caps count active subscribers only; paused, cancelled, and expired subscriptions do not count. SimpleSubscription says it charges no transaction fees, though Shopify’s standard payment processing still applies. Free includes up to 100 active subscribers; Growth costs $39 a month and Premium costs $99 a month. The pricing note lists a 14-day trial; annual billing options are advertised for paid plans.
