Marginful is a Shopify app. You install it from your Shopify admin and approve read-only access. Marginful never changes your products, prices, orders, customers or inventory.

Before you start

  • You need a Shopify store and permission to install apps on it.
  • Every new store starts on the Free plan. No card is needed.
  1. Start the install

    Open the install page and enter your store's .myshopify.com address, for example your-store. If you picked a plan on the pricing page, the install page shows it.

  2. Approve access in Shopify

    Shopify shows the access Marginful asks for. All of it is read-only: products, inventory, orders, customers and Shopify Payments payouts. See Read-only access.

  3. Approve a paid plan (only if you chose one)

    If you picked a paid plan, Shopify asks you to approve the charge on its own confirmation page. The charge appears on your Shopify bill. See Billing through Shopify.

  4. Open Marginful

    Marginful opens inside Shopify Admin. Your first sync starts automatically.

Note

You can also open Marginful in a browser or on your phone outside Shopify Admin. Set a password or a one-tap sign-in method in Settings → Security & language. See Sign-in and two-step verification.
