What is a PO Number?

A Purchase Order (PO) number is an internal reference number that your company uses for accounting or invoicing purposes. Adding your PO number ensures that your finance department can easily match incoming invoices with purchase orders.

Where to Enter the PO Number

  1. Log in to your seven.io account.

  2. Open the Account Settings section.

  3. Locate the field labeled PO Number.

  4. Enter your company’s purchase order number and save the changes.

How the PO Number is Used

  • The PO number will be printed on all future PDF invoices issued by seven.io.

  • It will also be included in the XML structure of ZUGFeRD invoices for automated invoice processing.

  • This allows both manual and automated workflows (e.g., ERP or accounting systems) to identify and reconcile the invoice faster.

Important Notes

  • Adding a PO number is optional. If your company does not require PO references, you can leave the field blank.

  • Updates to the PO number only affect future invoices. Already issued invoices remain unchanged.

  • You can change or remove the PO number anytime in your account settings.

Example Use Case

Your company requires all supplier invoices to reference an internal order number. By adding your PO number to your seven.io account, the number will automatically appear on both the PDF invoice and in the ZUGFeRD XML file, making life easier for your accounting team.
