Shopify Inventory Sync from ERP or 3PL
If you’re trying to sync inventory from a third-party data source into Shopify - such as a warehouse management system (WMS), 3PL provider, or ERP platform - you’ve probably already run into the limits of most apps.
Off-the-shelf tools often don’t support your specific data format, API, or logic. Worse, they may try to re-sync everything unnecessarily, slowing things down or running into rate limits.
We’ve solved this problem with a custom-built solution designed for scale, flexibility, and speed.
Sync inventory from any source - built for your business
We’ve built a lightweight PHP script that can be tailored to accept data from any external source and push it to Shopify efficiently.
It uses SKU or barcode matching, only updates inventory when it has actually changed, and is fast enough to run frequently - even across thousands or tens of thousands of products.
You can host it on your own cloud provider or virtual server, giving you full control over how and when it runs. No reliance on third-party apps or shared infrastructure.
Key features
- Share data from any third-party system (JSON format)
- Uses SKU or barcode for reliable matching
- Skips updates when inventory hasn’t changed
- Lightweight and fast, designed for large product catalogs
- Handles Shopify’s API rate limits safely
- Can be hosted on your own infrastructure
How we can help
- We can deploy and run the sync for you on your behalf
- Or we can deliver a customizable script that your developers can plug into your workflow
- Optional enhancements like logging, alerting, and dry-run/testing modes
Works with
- ERP systems
- Warehouse systems and 3PL providers
- External APIs or scheduled data drops
- Shopify Plus and Standard stores
