Hi Flinders
There is no direct report in the software that would return these results. An alternative would be producing two reports and sending them to Excel, to combine the results, the first being the Purchases [Supplier Detail] report (Reports>>Purchases>>Supplier). You will need to add in the Job no and due date fields to that report.
For the Paid date, you would be looking into the Supplier Payments History report (Reports >>Purchases >>Supplier payments). You would need to cross-reference the PO NO. on that report with that of the Purchases [Supplier Detail] report to get the payment date.
Please feel free to post should you have further queries.
