Hi there, @admingrandenviroca1.
Thanks for coming to the Community. I'd be happy to help share some steps on how you can get the invoice number to when printing an invoice.
If the invoice number is not showing up upon printing an invoice, you need to check if the Form Numbers option enabled on the invoice form style that you use. Let me walk you through so you'll see the number on your actual invoices.
Here's how:
- Click the Gear icon located in the upper right-hand corner.
- Under Your Company, click Custom Form Styles.
- Click the Edit link of the default invoice template.
- Click the Content tab, and click the header part of the invoice to expand more options.
- Under Form, check the Form Numbers box.
- Click Done.
