Shopify Inventory Management: Complete Guide

Effective inventory management is essential for running a successful Shopify store. Track too little and you'll face stockouts that frustrate customers. Track too much and you'll tie up cash in products that aren't selling. This guide covers how to use Shopify's inventory features to maintain optimal stock levels.

Understanding Shopify Inventory Tracking

Shopify's inventory system tracks stock quantities at the variant level. Each product variant (size, color, etc.) has its own inventory count, which decreases automatically when orders are placed and can be adjusted manually as needed.

Key Inventory Concepts

  • Available: Stock available for sale (not reserved by pending orders)
  • Committed: Reserved by orders but not yet fulfilled
  • On hand: Total physical inventory (available + committed)
  • Incoming: Stock in transfer that hasn't arrived yet

Setting Up Inventory Tracking

Enable Tracking for Products

  1. Go to Products in your Shopify admin
  2. Select a product to edit
  3. In the Inventory section, check "Track quantity"
  4. Enter your current stock level
  5. Choose whether to "Continue selling when out of stock" (for backorders)
  6. Save the product

Managing Product Variants

For products with variants (size, color, etc.), each variant has its own inventory:

  • Each variant can have different stock levels
  • Assign unique SKUs and barcodes to each variant
  • Track inventory separately per variant

Multi-Location Inventory

If you have multiple warehouses or retail locations, Shopify can track inventory at each:

Setting Up Locations

  1. Go to Settings > Locations
  2. Add each warehouse, store, or fulfillment center
  3. Assign inventory quantities per location for each product
  4. Configure which locations can fulfill online orders

Benefits of Multi-Location Tracking

  • Fulfill orders from the nearest location to reduce shipping costs
  • Know exactly where your stock is located
  • Support omnichannel retail (online + physical stores)

Adjusting Inventory

Manual Adjustments

Update stock levels when receiving shipments or making corrections:

  1. Go to Products > Inventory
  2. Find the product/variant to adjust
  3. Click the quantity to edit it directly, or use "Adjust" to add/subtract
  4. Add a reason for the adjustment (received, damaged, theft, etc.)

Bulk Editing

For large inventory updates:

  • Use the bulk editor in Products > Inventory
  • Export/import inventory via CSV files
  • Use inventory management apps for advanced bulk operations

Transfers Between Locations

Move inventory between locations:

  1. Go to Products > Transfers
  2. Create a new transfer specifying origin and destination
  3. Add products and quantities
  4. Mark as "Pending" until received, then mark "Received"

Inventory and Collections

Automated collections can use inventory as a condition:

  • "In Stock" collection: Inventory is greater than 0
  • "Low Stock" collection: Inventory is less than 5
  • Hide sold-out products: Only show available items in collections
Automate Inventory-Based Collections: AWSM Collections makes it easy to create collections that automatically show or hide products based on stock levels, keeping your store current without manual updates.

Inventory Reports and Analytics

Use Shopify Analytics to monitor inventory health:

Key Reports

  • Inventory snapshot: Current stock levels by product
  • Average inventory sold per day: Helps forecast reorder timing
  • Percent of inventory sold: Identifies slow-moving products
  • Days of inventory remaining: Predicts stockout dates

Using Data for Decisions

  • Identify bestsellers to ensure adequate stock
  • Find slow-moving items for promotions or discontinuation
  • Calculate reorder points based on sales velocity
  • Optimize inventory investment by reducing overstock

Inventory Management Best Practices

Set Reorder Points

Calculate when to reorder based on:

  • Average daily sales
  • Lead time from suppliers
  • Safety stock buffer

Formula: Reorder Point = (Average Daily Sales × Lead Time) + Safety Stock

Conduct Regular Audits

  • Perform cycle counts regularly (count portions of inventory on rotation)
  • Reconcile physical counts with Shopify records
  • Investigate and document discrepancies

Use SKUs Consistently

  • Create a logical SKU system (e.g., CATEGORY-PRODUCT-VARIANT)
  • Use SKUs for all products and variants
  • SKUs make inventory management and fulfillment more efficient

Common Inventory Problems

  • Stockouts: Lose sales and frustrate customers. Solution: Set reorder points and safety stock.
  • Overstock: Ties up cash and warehouse space. Solution: Use data to forecast demand accurately.
  • Discrepancies: Physical vs. system counts don't match. Solution: Regular audits and adjustment tracking.
  • Variant confusion: Wrong items shipped. Solution: Clear SKUs and proper variant naming.

Conclusion

Good inventory management balances having enough stock to meet demand without tying up excess capital. Use Shopify's tracking features, monitor your reports, and establish processes for receiving, auditing, and reordering. The goal is visibility and control over your inventory at all times.
