OPENSUBS PLATFORM

10 min

Your selling plans from [Configure your store](https://docs.opensubs.com/platform-v2/live-for-new-orders/configure-your-store.md) are already on your products; this step makes the offer visible. The rule underneath: widgets decide what shoppers see, plans decide what bills.

> [!NOTE]
>
> **Switching?** Leave the old platform's plan groups alone: attached, active, in their admin. Current subscriptions bill through them. Only their widget comes down, in the step below; that stops their new signups and nothing else.

**1. Place your widget**

* Open the theme editor and go to your product template.
* Add the **Subscription options** block near the buy buttons. The block hides itself on products with no plans, so placing it store-wide is safe.

* If your theme needs the app embed for quick-view, enable it at **Settings > Extensions**.
* Switching? Remove or hide the old platform's widget while you're in here.

**2. Save and check the page**

* Click **Save**. The swap is done.
* Your product page now offers one-time *and* your subscription plans, priced right.
* Using a sidebar cart with a "switch to subscription" upgrade? Confirm it offers your OpenSubs plans now.

> [!TIP]
>
> **Checkpoint:** exactly one subscription offer on the page: yours. If you're switching, the old platform's existing subscriptions are still billing, untouched.

> [!NOTE]
>
> Widget not showing later? [When the subscribe option disappears](https://docs.opensubs.com/platform-v2/run/when-the-subscribe-option-disappears.md) is the fix; **Settings > Extensions** shows each surface's placement.

> [!NOTE]
>
> **The revert, if you ever need it.** Two steps, both on your side:
>
> 1. In the theme editor, take the **Subscription options** block back out.
> 2. In the OpenSubs admin, delete your plan groups at **Settings > Selling plans**.
>
> Your offer is gone from the store. New store? You're selling one-time only, exactly as before. Switching? The old platform's plans and subscriptions never stopped; re-add its widget and its offer is back. Anything your team already sold on OpenSubs keeps billing until you cancel it. That's the whole undo.
