Currently, you are unable to filter purchase orders based on their invoiced status. 

On the main menu, click on the Orders tab. If you are connected to more than one Coupa customer, select their name from the Select Customer dropdown menu. You can see Molex purchase orders only if you have access. 

You cannot change a price on a PO through the CSP. If you need a change order on a PO, talk to your Molex about its policies.

You can invoice multiple times against a single PO. Just click the gold coin icon for the PO as you normally would and enter the amount you'd like to appear on the invoice. The next time you want to invoice against the PO, just do the same thing. 

If a PO transmission results in a connection timeout because there was no response from the supplier, Coupa will try to resend the PO up to four times at five minute intervals.

You can let your customers know that you've received the order. Some Coupa customers like their suppliers to use that field. Ask them if they want you to use it.

A soft closed PO is a PO that Molex can reopen, for example, if an invoice or credit memo submission is needed, or if a PO is closed prematurely or by mistake.

You cannot invoice against a soft closed PO. For more information, see View and Manage POs.

On the main menu, click on the Orders tab. In the PO table that appears, choose the PO you want to invoice, and then click on the yellow coins to create an invoice. For more information, see invoices training video

For more information, see Create or Edit an Invoice.

To create a non-PO backed invoice, click on the Invoices tab on the main menu. Select Molex from the Select Customer dropdown menu. Click on the Create Blank Invoice button above the Invoices table. For more information, see Create or Edit an Invoice.

If you don't see the Create Blank Invoice button, contact https://www.molex.com/coupa-supplier support/form and ask them to configure your supplier account so that you can submit invoices without a backing PO.

Your account needs to be configured to handle invoices through Molex’ Coupa instance.  

Here are the options to invoice to Molex:

  • The CSP, where you sign in to manually flip a PO to create an invoice.  
  • Supplier Actionable Notifications (SAN), where you act on an email without logging in to the CSP. 
  • cXML, where you can automate the process of sending an invoice file using Coupa's standard cXML format. 
  • API, where you can automate the process of sending an invoice file using Coupa's API.  
  • If suppliers are not leveraging the CSP or SAN to invoice Molex, they will need to send their invoice via PDF to invoices@molex.com.  Invoice copies should include the following information
    • PO number, material number or service description
    • PO line number, quantity, currency, price per unit and unit of measure.
    • An invoice number, invoice date and payment term
    • Your company name, address and remit to address/details
    • The name and email address of the person responsible for this order 
    • Invoices must be billed to the entity stated on the PO 
    • One PDF per email is preferred. Multiple invoices can be sent in one email, but each invoice must be a separate attachment
    • Don't re-send your copy to us as a hard copy as it is not needed. Help us to avoid duplication
  • If you cannot send invoices through email, continue to submit by mail to your regional location 

If you are unable to submit your invoice to us electronically, please continue to submit your invoice by mail to your regional Molex location. 

Yes, if a customer deleted an invoice number, you can reuse it. 

Yes, you can. You can upload your PDF invoices in the following ways:

  • Log in to the CSP to create an invoice and attach the PDF. You don't need to contact your customer to do this, and it only takes a moment. 
  • Email the PDF directly to Molex. When sending in invoices, 
    • One PDF per email is preferred. Multiple invoices can be sent in one email, but each invoice must be a separate attachment 
    • Don’t re-send your copy to us as a hard copy as it is not needed. Help us to avoid duplication
    • If you can’t send invoices through email, continue to submit by mail to your regional location 

On the main menu, click on the Invoices tab, look for invoices that are still listed as drafts. They need to be edited and then submitted. If the invoice is not there, it's not in the system. 

You can add shipping charges at the bottom of the invoice or at the line item level. 

Invoices against a PO don't need accounting information, because that information is part of the requisition and is carried over to the PO. When an invoice references a PO line number, Coupa takes the accounting information associated with the line and adds it to the invoice.

To create a credit, enter a negative quantity. For more information, see Create a credit note.

Once an invoice is submitted, it can't be changed in any way. For more information, see Create or Edit an Invoice.

You can invoice multiple times against a single PO. Just click the gold coin icon and enter the amount you'd like to appear on the invoice.

Once an invoice has been submitted, it can't be changed in any way. This ensures invoice processing integrity. However, you still have options:

  1. Ask Molex to reject or void the existing invoice. You can then create a new one.
  2. Create a new credit memo that credits Molex for the original value, and then create a new invoice.

Ask your customer which method they prefer.

It means your invoiced amount differs from the PO by more than your customer allows without manual approval. If an invoice has been on hold for a while, ask Molex to review it.

Just create a new invoice to replace the one that was rejected.

Nothing. The invoice is in Molex’s queue and you'll be paid based on the payment terms.

For questions regarding payment information, contact Molex directly. Some payment details might be on the invoice document in Coupa, but not all customers update this information.  

It depends on how Molex has you set up.  

Log in to the CSP and click on the Orders tab on the main menu. Choose the PO you’d like to create a credit for and select the red coins. You'll create a negative invoice with either a negative quantity or a negative amount. For more information, see Coupa Supplier Portal.

If you don't have a PO and Molex has given you permission to create invoices without a backing document, click on the Invoices tab on the main menu. Click on the Create Blank Invoice button above the Invoices table.  

If you don't have a PO and Molex has given you permission to create invoices with a backing document, click on the Invoices tab on the main menu. Click on the Create Invoice from Contract button above the Invoices table.

SupplierNet will be replaced by Coupa for indirect sourcing and procurement activities. The process for Direct Material MRP purchase orders will remain unchanged. Coupa will be used only for indirect purchase orders and invoices.

All active suppliers for indirect procurement will be required to provide a PO email contact in order to continue transacting with Molex through Coupa. The general communication email requests confirmation of the PO contact email and identification of the primary contact.

The PO Contact will be responsible for receiving purchase orders from Coupa and enabling the fulfillment of Molex purchase orders for goods and services.

The Primary Contact will be responsible for receiving future communications regarding the Coupa transition and for setting up additional users in the Coupa portal to access payment status and create invoices electronically.

Changes should be processed per Molex vendor update process. Please contact Molex Supplier Support for help if you need guidance. 

Suppliers only need to confirm their email address in order for Molex to continue transacting with them. However, some of the anticipated benefits of joining Coupa include the ability to receive and confirm purchase orders and submit invoices electronically, as well as improved visibility into the status of electronically routed transactions.

Direct material MRPP prurchsae orders and process will not change, the Coupa system will only be used for Indirect purchase orders and invoices. 

Components incorporated into Molex products are considered direct, if not they are indirect. 

if a supplier does not have a PO and Molex has given permission to create invoices without a backing document, invoices will be processed in Coupa. Access invoices tutorials for details.
