Understanding Inventory Quantities
When you adjust inventory in Sellbrite, you're updating a product's On Hand quantity. Only On Hand quantities can be adjusted manually.
Sellbrite tracks inventory using three quantity types:
Quantity Type | Description |
On Hand | The physical quantity you have in stock. This is the value you can update. |
Reserved | Inventory committed to open orders that have not yet shipped. |
Available | Inventory available for sale after reserved quantities are deducted. |
Note: Inventory quantities should only be updated in Sellbrite. Adjusting inventory directly within a connected sales channel can interfere with inventory synchronization. If this has already occurred, contact support for assistance.
Adjust inventory using the Bulk Editor
If you need to update inventory for multiple products at once, the Bulk Editor is usually the fastest option.
To use the Bulk Editor, go to Products > Inventory then select Bulk Editor.
The Bulk Editor displays your inventory in a spreadsheet-style grid.
You can:
Edit quantities directly in the On Hand column
Select multiple cells at once
Copy and paste values from external spreadsheets
Drag values down to fill multiple rows
When finished, save your changes. You can also add a note that will be recorded in the inventory transaction history.
Adjust Inventory Manually
If you only need to update a small number of products, you can adjust inventory directly from the Inventory page.
Select the On Hand quantity to update inventory and save your changes. If a product exists in multiple warehouses, the quantity may not be editable unless you first filter the inventory view by warehouse.
You can also update inventory from the product page by opening the product and selecting the Inventory tab.
Adjust Inventory using an Inventory CSV file
Inventory CSV imports are useful when making large inventory updates outside of Sellbrite.
First, export your inventory by going to Settings > Export Data > Inventory.
As a part of the export process, you can select a warehouse and optionally filter by product category.
The Inventory CSV allows you to update:
Quantity
Cost
Bin Location
Important: Do not remove the first three rows of the spreadsheet.
After making your changes, import the file back into Sellbrite by going to Settings > Import Data > Inventory CSV File.
During import, you'll choose one of two quantity update methods:
Actual Quantity
Use Actual Quantity when the quantities in the spreadsheet represent the final, correct inventory counts.
The imported quantities will replace the existing quantities in Sellbrite.
Quantity Adjustment
Use Quantity Adjustment when the quantities in the spreadsheet should be added to the existing inventory.
Example:
Current quantity: 10
CSV quantity: 5
Result: 15
After selecting your import method, choose the destination warehouse and upload the file.
