To add quantities from the Invoice screen:

1. Click Inventory > Items > Add > From Invoice or P/O > Rcv Invoice. 
2. The Select A Vendor window will appear. Choose the vendor, then click OK.
3. The Receive Invoice window will appear. Enter the Invoice # at the top, then click Add Line at the bottom.
   
    
4. Enter or select the vendor style. The Copy Details window will appear.
   
    
5. Click the Bulk Master (highlighted blue) and click OK. The Allocate window will appear.
6. Total Cost and Description will prefill based on what was entered last shipment. You can update if necessary. Then enter # Pieces, Markup, and click OK.
