Medusa Assets & Services Plugin

A Medusa.js plugin for managing customer-linked product instances and service subscriptions.

Overview

The assets-services plugin extends Medusa with the ability to manage physical product instances (assets) and related service subscriptions (service instances) linked to individual customers. It supports a wide range of after-sales and post-purchase use cases, such as:

• Assigning products (with serial numbers) to customers
• Attaching services to assets (e.g. maintenance plans, insurance, calibration)
• Selling standalone services (e.g. rentals, diagnostics)
• Managing product relationships (e.g. compatible services, spare parts)

The plugin enhances the Medusa admin interface with new panels for managing assets, services, and product references, enabling rich linking and management flows.

This plugin is used in Open Self Service, a composable customer portal for viewing and managing owned products, warranties, and activating additional services. You can also use the plugin independently.
