Hello,
i can't find the Letterheads tab in Company option?  

Good day,

Is this only available in the Enterprise version? I can't find the LetterHeads tab in  the Community Version

In Odoo, you can print quotations and other documents on a company letterhead by using the "Letterheads" feature in the "Settings" menu. This feature allows you to upload a letterhead template in Word or PDF format, and then apply the template to your documents when printing them.

To use the "Letterheads" feature, first go to the "Settings" menu and select the "Company" option. Then, go to the "Letterheads" tab and click on the "Create" button. In the "Letterhead Name" field, enter a name for the letterhead template, and then click on the "Choose File" button to select the template file from your computer.

Once the template file has been uploaded, you can preview the letterhead by clicking on the "Preview" button. If the preview looks correct, you can save the letterhead by clicking on the "Save" button.

To apply the letterhead template to your quotations and other documents, go to the "Invoicing" menu and select the "Configuration" option. Then, go to the "Reports" tab, and in the "Quotation Report" section, select the letterhead template that you created from the "Letterhead" dropdown menu.

Once you have configured the letterhead template for the quotation report, it will be automatically applied to your quotations and other documents when you print them. The template will be merged with the document content to create a final document that is printed on the company letterhead.
