Medusa Services & Assets

Overview

The Product Relations Plugin for Medusa extends your e-commerce capabilities by adding dedicated entities to manage customer purchases and services more effectively. This plugin introduces two key concepts:

• Assets: Track physical products with unique identifiers (like serial numbers) that customers have purchased
• Service Instances: Manage services that can be either attached to assets (like extended warranties, maintenance plans) or exist independently (such as rentals, repairs, or standalone services)

Additionally, this plugin enhances product variants by allowing you to create references to other products, such as spare parts or replacements, making it easier to manage product relationships and accessories.

When plugin is installed, new menu options should appear in backoffice. There are dedicated pages to manage Service instances and Assets with ability to create, modify and delete them.

You can find admin API definition in repo files.

This starter is compatible with versions >= 2.4.0 of @medusajs/medusa.
