How We Built Seamless ERP Integration for Medusa: Base.com Case Study

Source: Dev.to

The manual approach is a nightmare

• Hours spent copying product data between systems
• Inventory discrepancies leading to overselling
• Order details manually entered into your ERP
• Human errors causing fulfillment delays
• Scaling becomes impossible as your catalog grows

For businesses using Medusa as their e‑commerce platform, the challenge is finding the right integration that keeps everything in sync without breaking the bank or requiring a team of developers.

Why a Proper Medusa‑ERP Integration Matters

• Real‑time inventory accuracy – never oversell products.
• Automated product management – new products added in the ERP appear instantly in the store with full descriptions, images, and pricing.
• Seamless order flow – orders move from checkout to the warehouse without manual data entry.
• Scalability – grow from hundreds to thousands of products without additional staff.

A comprehensive integration should handle the complete product and order lifecycle:

Product synchronization

• Titles, descriptions, images, media assets
• Categories, collections, custom attributes

Pricing

• Base and sale prices across multiple currencies
• Tax configurations, volume discounts, pricing rules

Inventory management

• Real‑time stock levels across multiple warehouses
• Stock location mapping, low‑stock alerts, inventory reservations

Order synchronization

• Automatic order creation in the ERP at checkout
• Customer and shipping details transfer
• Real‑time status updates, payment and fulfillment tracking

Base.com ERP Overview

Base.com (formerly BaseLinker) is a popular ERP system used by thousands of e‑commerce businesses. It offers tools for inventory management, order processing, multi‑channel sales, and warehouse operations.

Challenges with Medusa + Base.com

• Managing thousands of product variants without automation
• Maintaining accurate inventory across multiple warehouses in real time
• Automating order flow from storefront to ERP for fulfillment
• Keeping product pricing and descriptions synchronized

Our Solution: Open‑Source Medusa Plugin for Base.com

We built a bidirectional synchronization plugin that:

• Automated product sync – a single API endpoint fetches titles, descriptions, images, all variants, pricing across markets, and stock levels from every connected warehouse.
• Intelligent mapping – helper database tables maintain relationships between Base.com and Medusa IDs for fast lookups and data consistency.
• Real‑time order creation – captures order details, maps Medusa products to Base.com IDs, creates the order in Base.com with the correct status, and updates inventory on both sides.
• Scheduled synchronization – run automated syncs on a configurable schedule, continuously in the background.

Workflow Overview

1. Catalog management – your team updates products, inventory, and pricing in Base.com.
2. Sync execution – the plugin runs on schedule or on‑demand, pulling all changes automatically. New products appear in Medusa, details and prices update, and inventory reflects real‑time warehouse data.
3. Order processing – when a customer completes checkout, Medusa captures the order and the plugin instantly creates the corresponding order in Base.com, enabling the warehouse team to begin fulfillment immediately.

Measurable Benefits

• Handles over 10,000 products in minutes with 100 % inventory accuracy
• Saves 20+ hours per week on manual data entry
• Scales seamlessly as the catalog grows
• Creates ERP orders within seconds of checkout

Extending the Integration to Other ERP Systems

The same approach works for virtually any ERP, including:

• SAP Business One – mid to large businesses
• Microsoft Dynamics – comprehensive business management suite
• NetSuite – cloud‑based ERP and financial management
• Odoo – open‑source ERP for growing businesses
• Custom proprietary or legacy systems with a REST API or accessible interface

• Custom field mappings for unique product attributes
• Advanced pricing rules for complex business models
• Sophisticated multi‑warehouse logic
• B2B customer‑specific pricing tiers

• Custom synchronization schedules with filters to sync only what you need
