Complete overview of the inventory update process

The Four Methods

1. Manual Updates

Best for: Individual SKU updates, quick corrections, small inventories

Update inventory quantities one SKU at a time by searching for specific items in OneCart and changing their quantities directly. Changes take effect immediately across all connected platforms.

2. Bulk Upload (Overwrite Method)

Best for: Complete inventory resets, stock audits, setting accurate base inventory

This method overwrites existing quantities with the values you provide in an Excel spreadsheet.

Example:

  • Current stock in OneCart: 55 pieces
  • Excel spreadsheet shows: 10 pieces
  • Result: OneCart quantity becomes 10 pieces (overwrites the 55)

When to use:

  • Conducting full inventory audits
  • Setting up initial stock levels
  • Correcting major discrepancies
  • After physical stock counts

3. Inbound Stock (Addition Method)

Best for: Receiving new stock from suppliers, adding inventory

This method adds the quantities you specify to existing stock levels.

Example:

  • Current stock in OneCart: 55 pieces
  • Excel spreadsheet shows: 10 pieces (inbound)
  • Calculation: 55 + 10 = 65 pieces
  • Result: OneCart quantity becomes 65 pieces

When to use:

  • Receiving shipments from suppliers
  • Adding manufactured products
  • Restocking from transfers
  • Any scenario where you’re adding to existing inventory

Learn how to use Inbound Stock


4. Outbound Stock (Subtraction Method)

Best for: Removing inventory for various reasons

This method subtracts the quantities you specify from existing stock levels.

Example:

  • Current stock in OneCart: 55 pieces
  • Excel spreadsheet shows: 10 pieces (outbound)
  • Calculation: 55 - 10 = 45 pieces
  • Result: OneCart quantity becomes 45 pieces

When to use:

  • Recording damaged or defective products
  • Inventory losses or shrinkage
  • Internal use or samples
  • Corrections for over-counted stock

Key Differences Summary

Method Action Best For User Calculates

Outbound Stock Subtracts from existing Removing inventory Movement amount

Advantages of Each Method

Bulk Upload

  • Advantage: Complete control over final quantities
  • Use case: “I want my SKU-001 to have exactly 100 pieces”

Inbound & Outbound Stock

  • Advantage: No need to calculate final quantities
  • Use case: “I received 50 pieces, just add them to whatever I already have”

Choosing the Right Method

Ask yourself:

  1. Do I know the exact final quantity I want? → Use Bulk Upload or Manual
  2. Am I adding stock to what I already have? → Use Inbound Stock
  3. Am I removing stock from what I have? → Use Outbound Stock
  4. Is this just one or two SKUs? → Use Manual
