How to Set Up Stock Sync Using a CSV File

This guide explains the different ways you can set up a stock (inventory) sync in Stock Sync using a CSV file, based on common customer scenarios.

1. Upload a CSV File Manually

Use this option if:

• You receive a CSV by email
• You want to upload the file yourself daily or whenever it updates

Steps:

1. Go to Create New Feed → Add Feed.
2. Select Upload File as the connection method.
3. Upload your CSV file.
4. In Step 2: Mapping, map:

• Product Identifier → SKU column in your CSV
• Store Product Field → Inventory Quantity (map to your quantity column)

5. Save and run the feed.

Stock Sync will update only the stock—it will not recreate existing products.

2. Sync Automatically Using a URL (CSV Link)

Use this method if your supplier or system provides a direct URL to the CSV.

Supported examples:

• Direct download links
• Public CSV URLs
• Supplier-generated URLs
• Dropbox shared links (must be a direct file link)

Steps:

1. Go to Create New Feed → Add Feed.
2. Select Import from URL.
3. Paste the direct CSV link.
4. Map SKU and Quantity.
5. Enable Schedule and choose Daily, Hourly, or preferred interval.

Notes:

• Some URLs containing redirects or expiring tokens may fail. If the link expires, request a non-expiring link from your supplier.
• Dropbox links must point to the file, not a folder.

3. Connecting via Dropbox CSV

For Dropbox-hosted files:

• Ensure the link is a file link, not a folder link.
• The share settings must allow public access.
• Use the Dropbox connection method if needed.

Steps:

1. Go to Create New Feed → Add Feed.
2. Choose Dropbox.
3. Insert the public file link.
4. Map SKU and Quantity.
5. Enable scheduling if you want automatic updates.

4. Ensuring Automatic Sync Works

To automate stock updates:

• The feed must include a valid URL or connected cloud source
• The feed must be enabled
• Scheduling must be activated (Daily/Hourly)
• Your plan must support scheduled syncs

You can confirm automation under Feed Details → Sync Schedule.

5. Common Issues

• Unmatched variants: SKUs in your CSV do not match your Shopify product SKUs.
• Password‑protected or expiring URLs: These cannot be used for automated fetches.
• Missing quantity mapping: Ensure the quantity column is selected.
• File is a folder: Ensure your supplier shares a direct file.

6. Additional Features

• Merge variants: If a product receives new variants, Stock Sync can merge them.
• Skip existing products: Add feeds automatically skip SKUs that already exist.
• Overwrite stock: Recommended setting for inventory feeds.

By using any of these methods—Upload File, URL import, or Dropbox—you can keep your store inventory synchronized automatically or manually depending on your workflow.
