One price, set by your orders
A fixed monthly price, counted on orders that saw an offer, not every order in your store. Your plan never changes without your click. Paid plans start with a 14-day free trial, and the first 200 stores keep their price for life.
Before you switch
The short answers, for merchants already running upsells.
Do I need Shopify Plus?
No. Sellbell works on every Shopify plan.
Can I run it next to my current app?
Shopify gives the post-purchase page to one app at a time. You switch in Settings › Checkout, and you can switch back the same way.
Does it show after Apple Pay?
Shopify shows no post-purchase page after Apple Pay, Google Pay, Klarna or a gift card. Those orders finish normally, without an offer.
Can I import my funnels?
No app can read another app's funnels, so nobody can honestly offer a one-click import. You rebuild them in Sellbell: trigger, upsell, second upsell, downsell.
How do I start?
Connect your store, choose the product that triggers the offer and the product you want to offer, then publish. Last, choose Sellbell as your post-purchase page in Settings › Checkout.
What happens if I uninstall?
Billing stops, and your funnels and statistics are deleted when Shopify asks us to erase your store's data.

Connect Sellbell to your store
Shopify will ask you to approve these permissions:
- Read your products and collections, to build offers
- Read your store's languages, to translate them
- The store owner's contact details, which Shopify lists on this screen. Sellbell doesn't store them
You stay in Shopify. Sellbell never asks for a password.
