Invoices interface
If you’d like to receive your invoices electronically and process them digitally without manual effort, you have several options.
By default, we send invoices as PDFs by email. If you wish, we can also attach a structured XML invoice for automated processing.
Alternatively, you can receive your invoices through the invoice interface and import them directly into your ERP system. Please note that this uses a different version of the XML format SAP IDoc – see the notes below.
If you already use the Order Inject interface for order data, references such as order and line item numbers can be transferred directly from the order to the invoice.
Credit notes and cancellation invoices can also be handled electronically.
Important notes
PDF invoices are only sent by email. If required, we’ll add a structured XML format (SAP IDoc version INVOIC02) as an attachment.
For invoices transmitted via the interface, we use a different SAP IDoc version (INVOIC01).
Despite careful testing, it’s possible that some invoices may not be processed electronically. Please ensure you’re able to receive and process PDF invoices from Unite in such cases.
We’re continuously working to meet European standards for electronic invoices, especially EN 16931. You’ll find more information in our support article about e-invoicing.
Format and transport protocol
For invoice transmission via interface, Unite uses the SAP IDoc INVOIC01 XML data format. Transmission is carried out via HTTPS by default.
If you require a different format or transmission protocol, please reach out to your Unite contact or to our Sales Team.
