10 Best Shopify Upsell and Cross-Sell Apps in 2026

Introduction

For Shopify merchants using Cash on Delivery (COD) as a payment method, capturing orders efficiently and maximizing average order value can be a challenge. Standard Shopify checkouts often lack the dedicated features needed to handle COD workflows, prevent fraud, and drive upsells or cross-sells at the point of purchase. Dedicated COD form apps solve this problem by giving merchants flexible forms, automation, and sales-driving tools tailored to COD orders. When choosing a Shopify upsell and cross-sell app for COD, merchants should look for streamlined form design, upsell capabilities, fraud prevention, analytics, and integration with their existing tools and languages.
