Let's make sure you'll be able to input your country on the correct field, richard-richardk,

I have another way of how this will appear on all your forms. While we don't have a field where you can enter your country specifically, you'll want to design and import a template so you can use this every time you want to show it on your forms. To do this, you can follow the steps below:

To map the fields:

1. Open your DOCX template.
2. As you design your template, identify text or fields that don’t change with each print. Logos, company information, certifications, and such are static info. Make it part of your template.
3. Replace all fields with scalar or table fields, as appropriate to your chosen form type.
4. Make sure all fields match the EZ Map fields defined in the EZ Map catalogue.

Then, to save and upload the template: 

1. Click the Gear ⚙ icon, then Custom Form Styles.
2. Select the New style ▼ dropdown menu, then Import style. If you don't see Import style? Go to the Gear ⚙ icon, then QuickBooks Labs. Then turn on Import Styles.
3. Select a form type.
4. Select Upload your .DOCX file field, then find and select your .docx template.
5. Select Next.

For more details, you can check out this article for your guide: Import Custom Form Styles For Invoices or Estimates. Moreover, multilingual invoicing is available in QuickBooks Online (QBO). This automatically translates the invoice you send to your customers based on the language you selected. Go through this article for your reference: Send Invoices In Different Language.
