How to create a new purchase invoice from an existing purchase order.
Navigate to ‘Parts / Tyres > Tyres’ and then click on the ‘Purchase Orders’ tab in the bottom window pane. In the dropdown box in the top-left of the bottom pane, select the purchase order you would like to convert into an invoice and then click on “Add Stock”.
In the ‘Add Stock from Purchase Order’ window that appears, click into the search bar in the top left corner and type the invoice number for your new purchase invoice. Select a date for your purchase invoice, and then a supplier from the dropdown in the top-right. You can then begin recording the stock items included on this purchase invoice in the lower half of the open window.
