Your growth logic,
plugged into Shopify

StackBack is subscription management software built into Shopify. It works with your store's products, checkout and fulfilment, so every way of selling runs from one place: formats that win the first order, and subscriptions that keep customers buying. Every module shares one customer portal, one set of rules and one view of the customer, and new modules plug into the same foundation.

Frequently Asked Questions

What is subscription management software?

Software that runs a brand's subscriptions end to end: plans, payments, renewals, delivery schedules and the customer portal. StackBack does this inside Shopify, alongside bundles and flash sales.

Can I build a subscription website on Shopify?

Yes. Add StackBack to your Shopify store and every product page can sell subscriptions, with dedicated landing pages for subscriptions and bundles.

What's the difference between a curated box and a build-your-own box?

A curated box is a fixed set you choose. A build-your-own box lets the customer pick the items. StackBack runs both as one-time orders or subscriptions.

Do subscriptions work with my checkout?

Yes. They go into the cart like any product and check out on Shopify checkout or any quick checkout, including GoKwik and Shopflo.
