# How do I get the customer code to send a non-PO invoice?

## Symptom

How do I get the customer code to send a non-Purchase Order invoice?  
  
Why am I receiving the error !Customer code does not match any customer when creating a non-PO invoice?

## Cause

To create non-PO invoices for a buying organization, you must have either a trading relationship established with your customer or a unique customer code provided by them.  
  
If you are prompted to enter a customer code when creating a non-PO invoice, **it means you do not have a trading relationship** established with that customer in your account.

## Resolution

Contact your customer and request that they provide you with their **customer code** or send a [trading relationship](https://support.ariba.com/item/view/KB0394284) request to your account. Provide them with your [SAP Business Network ID (ANID)](https://support.ariba.com/item/view/KB0392438) when doing so.  
  
If your customer provide you their customer code, once you submit the non-PO invoice and they approve it, the trading relationship will automatically establish in your account.

## See Also

You can share with your customer the following documentation on how to generate a unique customer code: [*Receiving Non-PO Invoices from Unregistered Suppliers*](https://help.sap.com/docs/business-network-for-procurement/enabling-suppliers-on-business-network/how-to-generate-invoice-quick-enablement-customer-code#receiving-non-po-invoices-from-unregistered-suppliers)  
  
If you have a trading relationship established with your customer, but their company name does not appear in the drop-down list of customers when creating a non-PO invoice, it means the customer does not accept non-PO invoices. In the [customer's transaction rules](https://support.ariba.com/item/view/KB0393619), the following rule is disabled (set to *No*): *Allow suppliers to send non-PO invoices.*
