Introduction

Stock Adjustment is the process of manually increasing or decreasing product quantities in inventory to match the actual physical stock.
It is done when there are differences between the system-recorded stock and the actual stock due to damage, loss, returns, counting errors, expired items, or corrections after audits.
Stock adjustment ensures that inventory records are accurate and reflect the true quantity available for sale or use.

Vtiger’s Stock Adjustment

The Stock Adjustments module in Vtiger CRM enables your business to accurately and transparently adjust product stock levels. Whether stock levels increase or decrease due to purchases, sales, audits, or corrections, the module ensures that any change is recorded systematically.

Whenever you modify Qty. in Stock or Defective Stock values, a Stock Adjustment record is created, and the updated values are automatically reflected in the Products module. This allows your organization to maintain clean audit trails and reliable stock visibility across teams.

Key Features

  • Adjust Stock Quantities: Increase or decrease product quantity or defective stock.
  • Automatic Product Updates: Adjustments are instantly reflected in the corresponding fields in the Products module.
  • Approval-based Updates: Stock is updated only when the Stock Adjustment status is set to Approved.
  • Centralized Adjustment Records: Every adjustment is stored as a dedicated Stock Adjustment record.
  • Restricted Product Editing: Once enabled, stock fields in the Products module become read-only to ensure controlled changes.
  • Inline Actions from Products: Quickly initiate stock adjustments directly from a product record.
  • History Tracking: View all stock changes through the Stock Adjustments widget inside the product record.

Consider the Scenario

ABC Industries is an FMCG company. They oversee daily stock management, ensure product availability, and handle all inventory-related transactions using Vtiger CRM.

During a weekly physical stock audit, the warehouse team discovers:

  • Product A shows 98 units in the system, but 93 units are physically available.
  • They also found 5 damaged units in a corner storage shelf that were not recorded.

When

Stock Adjustment is used when:

  • There is a mismatch between system stock and physical stock.
  • You must increase or decrease stock due to:
    • Damage
    • Theft or loss
    • Miscounting
    • Expiry
    • Sample usage
    • Internal consumption

What

The team performs a Stock Adjustment entry to correct the system quantity:

  • Reduce stock for damaged or missing items
