Ariba Network

For frequently asked questions regarding the Ariba Network, please visit our Supplier Information Portal.

Invoicing

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 AP@splunk.com and any invoices outside North America to Intl_AP@splunk.com

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.

Payment FAQ

Yes! Our global payment terms policy is effective across all of our suppliers globally. Our global initiative will help to ensure our systems, processes and payment terms are optimized to ensure our suppliers are given more payment transparency and paid on-time globally. If you have any questions, please contact your sourcing partner within Splunk.

When you transact with Splunk via the Ariba Network, you may check the payment status of your invoice directly on the Ariba Network under “invoices.”  This is the fastest way to check payment status. Here are step-by-step instructions for suppliers to check payment status on the Ariba Network using your account login.

Because payments will be paid according to a consistent process, it will enable a more predictable cash flow for you, our valued supplier.

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.

Supplier ESG

Suppliers play a pivotal role in sustainable procurement practices. Splunk is launching a sustainable procurement program to monitor sustainability performance in our supply chain.

As an integral service provider in the delivery of our products, we are reaching out to you to contribute to our efforts in advancing sustainability performance.  Your company has been identified as a key supplier, thus Splunk is counting on your commitment to support this initiative.

Our aim is to work with suppliers to improve sustainability performance. There are no minimum score requirements at the moment, but Splunk might utilize the EcoVadis score baseline in the future.

Yes. The supplier fees depend on the size of your business and the region they are located in. For more information, please visit https://www.ecovadis.com/plans-pricing/ to see all subscription options.

If you already have a valid scorecard, you will not be asked to pay again; you may also share this scorecard with your other customers without paying again for 1 year after completion. You may also access the resources, corrective action plan module, and EcoVadis Support team, and take actions toward improvement that can be shared.

You have been selected for assessment based on a number of factors. The EcoVadis assessment (including fee) is tailored by sector and size of your business (From <25 employees to >1000 employees). For more information, please visit https://www.ecovadis.com/plans-pricing/

Yes, we are asking suppliers of services to have the assessment. One of the reasons we chose EcoVadis is because it is tailored according to the specific risks in different sectors, including risks in the service sector. The assessment covers not only environmental impact but also labor & human rights, ethics, and sustainable procurement.

EcoVadis gives you an independent assessment of your sustainability program including strengths and weaknesses. It also gives you a clear score – so you can monitor improvements over time. The EcoVadis platform is designed to help companies better manage and communicate their company's sustainability performance in a clear and actionable way. The assessment can also be shared with your other customers and there are over 800 companies now using EcoVadis to assess their supply chains. For more information, please visit this page: https://support.ecovadis.com/hc/en-us/articles/115002531387-Benefits-from-the-EcoVadis-solution-

Splunk does not have the resources to read and assess all suppliers’ credentials individually: this is why we have engaged with EcoVadis which has a standardized assessment approach and creates an easy-to-understand scorecard, with a score against four key areas: Environment, Labor & Human Rights, Ethics and Sustainable procurement. In this way, like-for-like performance and information can be assessed across our entire supply chain and benchmarked against supplier sectors.


The aim of platforms such as EcoVadis is to reduce the level of reporting we all need to complete and allow sharing of information instead. The scorecard produced is not specific to the request from Splunk and can be shared with many buyers to demonstrate your performance.

Supplier Questionnaires

As a prospective supplier or an existing supplier of Splunk, you may receive a questionnaire through our Ariba platform. Click HERE to learn more about completing a Splunk questionnaire.

The shorter questionnaires can be completed in only a few minutes. If you receive a longer security related questionnaire, it may take a few days to gather the answers to those questions and submit the questionnaire back into Ariba.

No. Please complete the questionnaire within the Ariba platform. This is the most efficient process for your company to communicate with Splunk.

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).
