# How Does Bulk Opening Invoices Work?

You can mark multiple draft invoices as Open from the invoice list page.

To bulk open invoices:

*   Go to **Sales** on the left sidebar and select **Invoices**.
*   Select the draft invoices that you want to open.
*   Click **Mark as Open** at the top of the page.

Zoho Books will validate the selected invoices before opening them. If any required details are missing, update those invoices and try again. Once the invoices are marked as Open, they will be treated as issued invoices and the applicable invoice PDF will be captured.
