May you please help me tracking no not printed on form?

Hello there, @lutendo-mlbrands.

Let's edit your sales form template to display the Shipping option so you can include the Tracking No field when creating and printing invoices in QuickBooks Online (QBO).

The Tracking No field will appear on your invoice once the Shipping option in your customised sales form template is activated. To do this, here's how:

1. Go to Settings ⚙ and then select Custom form styles.
2. Find the template and click the Edit option under the Action column.
3. Select the Content tab.
4. Click the Header section of the sample form.
5. Go to the Display section and click the box next to Shipping.
6. Select Done.

You can read this article for the complete guide to personalising and adding specific info to your sales forms in QBO: Customise invoices, quotes, and sales receipts in QuickBooks Online.

Once you're done, go ahead and create invoices with tracking numbers in QBO.

Also, you may want to check out this article as your reference to guide you in emailing or printing multiple sales forms in QBO: Email or print multiple sales forms in QuickBooks Online.

Let me know if you have other concerns about customising invoices and managing sales transactions in QBO. I'll gladly help. Take care, and have a great day, @lutendo-mlbrands.
