The Invoice Configuration has a new tick box called ‘Print Invoice No as a Barcode on Picking Slips’. When this is set to True a barcode for the Invoice Number will be printed on the top right of the picking slip.
N.b – Currently the barcode only prints when printing a single picking slip and not a batch.
This feature has now been updated to always print the barcode when the box is ticked please refer to http://www.acr.com.au/updates/invoice-configuration-print-invoice-number-as-barcode-on-picking-slip
