Adding bin location data to Shopify Order Printer packing slips

Managing inventory across multiple storage locations creates a common challenge: how do warehouse staff quickly find products when fulfilling orders? This guide shows you how to add bin location information directly to your Shopify packing slips, creating a simple but powerful solution.

Why add bin locations to packing slips?

This customization is perfect for businesses that:

• Store inventory across different warehouse sections
• Keep products in separate rooms or storage containers
• Use shelves, bins, or zones for organization

The business benefits are clear:

• Faster order packing with precise location guidance
• Quicker training for new warehouse staff
• Reduced fulfillment errors
• No need for separate location reference documents

Step 1: Setting up your metafields

Start by creating metafields to store your bin location data:

1. Go to Settings > Custom data > Metafields in your Shopify admin
2. Decide where to store your location data.
   • Choose "Product" under "Metafield definitions all variants share the same location
• Choose "Product variant"under "Metafield definitions" for variant-specific locations
• You can set up both if your inventory system requires it
3. Click Add definition, see image below

1. Configure the metafield with these settings:
   • Name: "Stock Location"
   • Namespace: inventory
   • Key: stock_location
   • Description: "Physical bin/shelf location where this item is stored"
   • Type: "Single line text"
   • You can leave the rest of the fields blank

2. Click Save

Step 2: Install Shopify Order Printer.

Go to the Shopify App Store and search for "Shopify Order Printer" or click link below to install

Step 3: Adding location data to your products

Now fill in the location information for your products:

1. Open a product in your Shopify admin
2. Scroll down to find the "Metafields" section
3. Locate your "Stock Location" field
4. Enter the location identifier (for example, "L1" for office inventory)
5. Save the product

Consider using a consistent naming system that works for your warehouse layout:

• "A12-B3" for Aisle 12, Bin 3
• "WH2-Z4-S8" for Warehouse 2, Zone 4, Shelf 8
• "R1-S3-B5" for Room 1, Shelf 3, Bin 5

Step 4: Customizing your packing slip template

Next, modify your packing slip template to display the location data:

1. In Shopify Order Printer page, navigate to Templates > Packing slip
2. Use the following template and add it to your Shopify Order Printer packing slip

3. If you have a custom packing slip, add the following code:

{% assign variant_bin = line_item.variant.metafields.inventory.stock_location_variant %} 
{% assign product_bin = line_item.product.metafields.inventory.stock_location %} 
{% assign bin_location = variant_bin | default: product_bin %}
{% if bin_location != blank %} 
  Bin location: {{ bin_location }} 
{% endif %}

4. Save your changes

This code first checks for location data at the variant level, then checks the product level if needed.

Step 5: Testing your implementation

Verify everything works correctly:

1. Create a test order with a product that has bin location data
2. After saving your template, go to the order details page
3. Click "More actions" > "Print packing slip"
4. Check that the bin location appears on the slip
5. Test with several different products to ensure consistency

Supporting multiple storage locations

If some products are stored in multiple locations, try this more advanced approach:

1. Create your metafield as described above, but select "Multi-line text" as the type
2. Add comma-separated locations in the product data (like "A1-B2, C3-D4")
3. Use this alternative code in your packing slip template:

{% assign product_locations = line_item.product.metafields.inventory.stock_bin_location | split: "," %}
{% assign variant_locations = line_item.variant.metafields.inventory.stock_bin_location | split: "," %}
{% assign stock_locations = product_locations %}
{% if variant_locations.size > 0 %}
  {% assign stock_locations = variant_locations %}
{% endif %}
{% if stock_locations.size > 0 %}
<span class="line-item-description-line">
Stock Locations: <b>{{ stock_locations | join: ", " }}</b>
</span>
{% endif %}

Troubleshooting common issues

When something isn't working quite right:

• Double-check that your metafield spelling matches exactly in both your product settings and template code
• Make sure you're using a consistent naming format for all your location data
• For large catalogs, consider using Shopify's bulk editor or CSV import to add location data to multiple products at once

This metafield customization gives you a professional warehouse management feature without additional costs. By using Shopify's built-in functionality, you've created a custom solution that can significantly improve your fulfillment efficiency and accuracy.

While this customization isn't directly related to most Shopify apps, it works perfectly alongside tools like DC Order Limits to create a more streamlined, error-proof fulfillment process for your business.
