Last month, we hosted an invoicing webinar for our suppliers on Ariba Network to share best practices and address common invoicing questions. We were excited about the level of interaction throughout the event and the questions we received. 

We’re answering all your questions in the form of a blog series organized by common themes. The third post for this series is on Invoice Details.  

To watch the webinar on-demand, register first before accessing it here. To review the general invoicing process, check out this video. 



Invoice details 

Q1: How can I submit an invoice if my customer hasn’t established a trading relationship with me? 

  • To transact with a customer on Ariba Network, there must be an established trading relationship. Please reach out to your customer. 

Q2: How can we see our customers’ invoice rules? 

  • You can view the different rules for each of your customers by going to your “Customer Relationships” page and pulling up the customer’s profile, which will include their invoice rules. Watch this video if you need help navigating.  

Q3: I can’t upload my invoice due to an error that says my “sold-to email address is invalid”.  

  • The sold-to email address should match the person who requested the goods or services. Sometimes, the default sold-to email address could be based on the contract’s contact person. Learn more in this article.

Q4: Where can I find my buyer’s contact information?

Q5: Can I ignore the UOM code in invoices if everything else is accurate and complete? 

  • Your buyer may require you to add UOM codes in your invoices before they could be accepted. Please refer to your buyer’s rules for clarification.

Q6: What does “Items-to- ship” mean? 

  • “Items-to-ship are orders/items that are awaiting shipment and do not have a ship confirmation attached to them. 

Q7: Does SAP Ariba account for all the different state and county’s sales tax rates? 

  • SAP Ariba’s tax codes are applied on line items and are made up of tax components. Each tax component has a specific tax rate and could be defined for a specific country, region, and state. If you have permissions or a user role for Tax Manager or Customer Administrator , you can create, edit, and delete tax components if needed. Refer to these articles to learn more about tax components and how to define tax components 

 Q8: Where can I get more information on my customer’s VAT/Tax ID?
