I need my tax invoice to show purchase order number

I can share some tips on how you can add the purchase order number, userinfo25.

You can set up a custom field for the purchase order number to appear on your sales forms. Here's how to do it:

1. Go to the Gear icon.
2. Select Account and Settings.
3. Choose Sales, then go to the Sales form content section.
4. Click the pencil icon in that section.
5. Enter "PO number" in the dialogue box beneath the heading Custom fields and select whether you want the field to be internal (only displayed in QuickBooks) or public (displayed in QuickBooks and displayed/printed on sales forms).
6. Select Save and then Done.

Additionally, the purchase order number will now be included in the delivery note once you've created one. I also recommend reading this article to help personalize the appearance of the invoices so your customers will recognize your brand.
