# How do I add and show a PO number on my invoices?

In Zoho Invoice, you can use the **Order Number** field in an invoice to record the PO (Purchase Order) number. When you enter a value in this field, it will be displayed as the PO number on the invoice.

To add a PO number to an invoice:

*   Go to the **Invoices** module on the left sidebar.
*   Click **\+ New** at the top-right corner.
*   Enter the purchase order number in the **Order Number** field.
*   Fill in the other required details.
*   Click **Save**.

Once saved, the order number will be displayed as the PO number on the invoice PDF.

**Note:** If you don’t see the **Order Number** field, make sure the **Use Simplified View** toggle is not enabled at the top of the invoice creation page.
