How to get started: checkout upsells & customizations

Overview

UpsellPlus allows you to add checkout upsells using Shopify’s Checkout Extensions. This guide walks you through setting up your first upsell offer.

Step-by-Step Guide

Log in to Shopify Admin

Open the UpsellPlus App
Go to Apps in the lefthand menu
Click UpsellPlus from the list of installed apps

Create a Checkout Upsell Offer
Click Create Offer and select Checkout Upsell
Choose a product to offer as an upsell
Customize the pricing, discount, and messaging

Head to the Checkout Editor to enable and position your upsell
Choose where the upsell should appear
Use drag-and-drop to position it within the checkout flow

Save



If you add the app and don't see the upsell appear in the checkout editor, check whether the upsell is activated in the app. Either way, you should see a default preview appear to help you with positioning.
