# How do I sign my invoice digitally?

You can sign your invoices digitally using the Digital Signature feature.

**Note:** This feature is available only for certain plans in the Indian edition of Zoho Books. Visit the [pricing](https://www.zoho.com/in/books/pricing/) page to check if it’s available in your current plan. Additionally, this feature is supported only on the [Zoho Books Windows app](https://apps.microsoft.com/detail/9P1K7PZCTMS0?hl=en-in&gl=IN).

To enable Digital Signature in your organization:

*   Navigate to **Settings** at the top right corner and then to _Customization_.
*   Select **Digital Signature**.
*   In the digital signature preference page, click the **Enable Signature** button.
*   In the following pop-up, check the **User Signature box** under _Invoices_ and _Credit Notes_ to enable digital signature in invoices and credit notes, respectively.
*   Click **Enable**.

You’ve now enabled digital signature for your organization. Once you finish creating an invoice, you need to sign it to send it to your customer. To sign the invoice:

*   Log in to your Zoho Books via the Windows application.
    
*   You can click the **Sign Invoice** button on the _What’s Next_ banner to sign or click the three-dotted button on the top right corner and select **Sign**.
    
*   If you have already connected your USB Token (certificate) in your system, Zoho Books would list it in the Sign with certificate dialog box. If you have already connected your USB Token (certificate) in your system, Zoho Books would list it in the Sign with certificate dialog box. If you haven’t connected your USB token and you have a new certificate to be included, you can connect it to your system and then hit the Refresh button for the system to list that certificate as well.
    
*   Choose the preferred certificate and click **Sign**.
    

**Insight:** USB token is a password-protected physical device used to store the digital signature certificate. The digital certificate can be issued by goverment ceritified authorities.
