Navigate to the Stock screen and select the 'Stock Order List' tab. From here click on 'Add Items' and choose 'View Items Sold Recently'.

The list shows items from the last month by default, but you can adjust the Sales Date Range. Customise your results using the drop-down menus just to the right of the date picker.
You can tick the Order checkbox to add items to your Reorder List, and they will automatically add 1 to the Qty column. You can over-type this with your own quantity if needed.
When you have finished your work, press Add to Order List, or if you wish to discard your changes / were just browsing, click Cancel.
