Invoice number not generating

Hi @nitin5060,

The way our free plugin creates an invoice automatically is when you select order email notifications in which it will be attached, under WooCommerce > PDF Invoices > Documents > Invoice > Attach to: The attachment process will create an invoice document with its respective number:

In the Professional extension, there is another way to create documents, based on the order status (without the need to attach it), specifically the Create automatically for setting. That is, if you select the Processing or Completed order status for this setting, the PDF document will be created only when the order reaches any of these order statuses:

In brief, if you are using only our free version, make sure you have selected the email notification(s) in which you want to fire the automatic PDF invoice creation.

Please follow these steps to find out if the issue is related with the email sending:

1. Install and activate the WP Mail Logging by MailPoet plugin
2. Open an existent Completed order, find the Send order email panel, on the right side, select Complete order and click on Save order and send email:
   
   
3. Then go to Tools > WP Mail Log, find your last email, and check if there are files in the Attachments column, and/or any notice on the Error column:
   
   
4. Share the results with us 🙂

Thanks for sharing those logs, but I’m not sure those have to do with this issue.
