I do not have permissions to invoice Lockheed Martin.  How do I set up an account through Exostar to access eInvoicing?

To obtain a user account, contact your company’s Organization Administrator.  If you do not know who your Organization Administrator is, please contact Exostar Support.

There are two roles available for LM eInvoicing:

  1. LM eInvoicing - “Full Access”
  2. LM eInvoicing – “View Only” (this role cannot create invoices)


What is the LM eInvoicing “View Only” role?

Lockheed Martin provides a “View Only” role for supplier users who do not need to submit invoices. The “View Only” access gives suppliers access into our eInvoicing supplier portal via Exostar to view beneficial information about status of their payments and invoices. Suppliers will be able to retrieve their own Supplier Paid and Pending Invoices Reports at any time. Reports can be pulled daily and with any date range allowing improved accessibility to data and faster reconciliation of payments via the LM eInvoicing application. This role will not provide access to the LMP2P Portal or allow for any updating within the eInvoicing application.

Below are some helpful links to assist with “View Only” access questions.

LM eInvoicing Supplier FAQs

Evaluated Receipt Settlement (ERS)

What is Evaluated Receipt Settlement (ERS)?

  • Items delivered by a supplier are received into Lockheed Martin's system
  • Receiving transactions creates an invoice in the Accounts Payable system
  • Accounts Payable system will generate payments based upon due dates according to Purchase Order terms

Please Note:  Invoices should never be submitted to Lockheed Martin for ERS type orders.


How do I know if my PO line/s are set up as ERS and I do not need to submit an invoice?

ERS lines on a purchase order are set up on a contractual agreement and indicated in the “Bill To” section of your Purchase Order.  Invoice lines designated as ERS in the LM eInvoicing Application will be marked with a message stating, “This PO line is designated as ‘ERS – only’.  Invoices are neither necessary nor accepted for this PO line.”  If you try to submit an invoice against an ERS line, the system will give you a notification stating, “This is an ERS line.  Invoices are not required for these PO lines.  Payments will be made according to PO terms upon receipt of the goods/materials/services.”


What is the process for generating Evaluated Receipt Settlement (ERS) Invoice numbers?

ERS Invoice numbers are systematically generated and will not match your company’s invoice number.  In general, Packing Slip numbers are used if available. ERS Invoice numbers are typically 10 digits and start with a 52 (i.e.:  52xxxxxxxx).  Payment details are available within the LM eInvoicing Application.  You can search for payment details by entering the Lockheed Martin generated invoice number (52xxxxxxxx) in the quick search or by searching by the Purchase Order number.

Lockheed Martin supplies your bank with remittance details, which include the purchase order number, invoice number/reference number and dollar amount. You must verify that your bank will provide you with these payment details and that your account accepts EFT.
