What is Light Account for PO and Invoicing?

Light Account (LA) allows free access to Ariba Network to process orders (PO) and invoices via email, regardless of number of POs and invoices or spent. However, LA only has limited functionalities.​

What are the functionalities of LA?

Using the LA, you will be able to view the last 50 transactions (PO and Invoices) with NTU at the Ariba supplier portal.   From the portal, you may trigger the PO to your email to process the order and later perform PO-Flip[1] to generate an e-invoice to your buyer.  It supports submission of basic documents through Ariba network such as Order Confirmation (OC), Advance Ship notice (ASN) and Invoice.  ​

[1] PO-Flip is a simple process enabled by Ariba Network that allows a supplier to easily convert a Purchase Order into an Invoice, and transmit that Invoice to the customer that placed the Purchase Order.

If the LA only shows the last 50 transactions, where can I find my transactions if there are more than 50?

You can find all your past transactions in your email account. Otherwise, you may contact your buyer for the PO​
