Sustainability and supplier diversity.

Yes, you can register. Splunk looks for diverse opportunities in the US and other parts of the world. Note that today we recognize WeConnect International as our international partner for women-owned businesses.

Acceptance into our supplier diversity registration does not guarantee business or opportunity. Splunk will use our database to search for potential suppliers on an as-needed basis. We encourage all suppliers to learn as much about Splunk and our many businesses.

A valid, up-to-date certification is required to participate in our system as a diverse supplier. It is up to you, the supplier, to keep the certification valid.

The Supplier Diversity team advocates for and supports diverse suppliers from within. Through attending events where diverse suppliers and certifying organizations are invited, Supplier Diversity helps identify suppliers and begins developing the relationship in anticipation of future procurement opportunities.

In order to work with Splunk’s Tier 1 supplier diversity program,it’s preferable that you are a certified diverse supplier; however, if you are a high-quality supplier with well-developed diverse suppliers in your own supply chain, you may qualify through our Tier 2 program.

We maximize and multiply diversity within our supply chain through our Tier 2 program. A Tier 2 supplier is the company that provides Splunk’s Tier 1 (Prime) supplier with products or services that will be provided to the end user. The Tier 2 company’s service or product does not have to be sold directly to Splunk for the spend to be counted in Splunk’s Tier 2 program.

For additional clarity, please see these definitions:

Second Tier Direct Contracting - Contracting opportunities in which a supplier does business with a Splunk First Tier supplier and for which the output can be directly traced to Splunk contracts (i.e., project-specific contracting).

Second Tier Indirect Contracting - Contracting opportunities in which a supplier does business with a Splunk First Tier supplier, but for which the output cannot be directly traced to Splunk contracts (i.e., general and admin expenses).

Purchase orders

As part of a Splunk global initiative to standardize and optimize our systems and processes, we are reinforcing compliance with our invoice submission requirements, including having a valid purchase order (PO) when required. Following our policies and processes will allow invoices to be routed efficiently through our systems, resulting in online payment tracking and on-time payments.

This means that unless an exemption applies, we will require a PO number on every invoice submitted. Invoices received without a valid, funded PO number will not be paid and the supplier will be notified of non-compliance.

The PO requirement aims to ensure Splunk pays only for goods, services and works that have been properly ordered and authorized. It also ensures invoices received by the Accounts Payable team can be processed efficiently to minimize delay to suppliers and contractors.

This policy applies to all locations, unless an exemption applies.

There are some pre-approved situations that do not require a PO, such as charity donations, insurance payments, etc.

We request that you ensure that a valid PO number is noted on the invoice before it is submitted to Splunk, for payment. If the PO number is not clearly indicated on your invoice, Splunk Accounts Payable will reject the invoice and notify the supplier.

The PO requirement will apply to orders placed on or after 1st February, 2021, and invoices received on or after this date.

If you have not received a PO or written purchase authorization, please reach out to your Splunk contact in Sourcing to confirm the Attn Line (if applicable), Splunk bill to, and PO # (if applicable), and to receive instructions for submitting an invoice without a PO.

SAP Ariba PO numbers for Splunk are 10-digits long and begin with the digits 45.

Currently, Splunk leverages SAP Ariba to process Supplier invoices.

In the case of national emergencies or disasters, yes. However, you still need to obtain a purchase order document and ensure you provide the quoted purchase order number on your invoice.

In situations where an urgent order is needed, it is possible to prioritize the creation of a purchase order number. Be sure to coordinate with your Splunk contact to follow the emergency order procedure they provide.


If already doing business with Splunk on the Ariba Network (AN), simply submit invoices through the AN. In the interim, submit North American invoices to and any invoices outside North America to

You may check the payment status of your invoice directly on the Ariba Network. Invoices may be disputed for any of a number of reasons and will always be sent back to the supplier email address along with the reasons the invoice is being disputed. Below are a few examples of invoices that are non-compliant:

  • No purchase order number noted on the invoice (Contact your Splunk Sourcing team member).
  • Purchase Order number is now completely consumed and used up.
  • Purchase Order number on your invoice does not match Splunk’s issued order.
  • Purchase Order number does not match the description/dates on the invoice.
  • Multiple purchase order numbers are referenced on one invoice. Please send individual invoices for each purchase order number.
  • Unit of measurement and unit price on invoice not matching with purchase order.
  • No attention Line or incorrect attention line mentioned on non-purchase order invoice.
  • Multiple invoices in one PDF document. Please send one invoice per PDF file.
  • No invoice number noted.

An Ariba Network Identification (ANID) number is a unique identifier of an Ariba Network account. Suppliers may maintain multiple ANIDs for various reasons. For each of these ANIDs, purchase orders and invoices – as well as transaction (monetary) volume – are counted for each customer relationship to determine when the thresholds are reached for supplier fees. Once the supplier reaches the chargeability thresholds in at least one relationship, transaction and subscription fees are assessed across all relationships within the same ANID. Suppliers with multiple ANIDs may roll up their accounts into a “multi-org” parent-child relationship to take advantage of per-relationship caps.

It is a best practice to make sure you receive a PO prior to delivering services or shipping materials that is correct and matches what you expect to be paid. You should work with your Splunk Sourcing Partner to make sure that the PO is accurate before you perform against that PO.

Splunk POs must reflect what a supplier expects to be paid. Splunk does not allow suppliers to invoice for items not on a PO (no non-PO charges are allowed in the AN for Splunk transactions.) If the buyer approves the additional items, these additional items should be added to the PO by the Splunk buyer in order for the supplier to be paid for these goods or services.
