From the main navigation bar, select Stock Adjustments, and click on 'Create New Stock Adjustment'.
Then, select the location first, and the 'Import via CSV' button at the top right-hand corner of the screen becomes clickable.
You will be required to upload a .CSV file that has two columns:
- Column 1 is the SKU of the products you need to adjust.
- Column 2 can be either the Quantity (which you would like to add or subtract from your current Stock on Hand) or the actual Stock on Hand value of your products.
Just name the column header accordingly, as shown in the template.
