Hi @simonehalfar,
Yes, this is entirely possible in WooCommerce. By default, WooCommerce sends an Order Confirmation email (either the Processing or Completed order email), but it does not generate an invoice unless an invoicing plugin is being used.
To prevent WooCommerce from sending invoices, first, check if you have an invoicing plugin installed, such as WooCommerce PDF Invoices & Packing Slips. If so, navigate to the plugin settings and disable automatic invoice generation.
Next, you can adjust WooCommerce email settings. Go to WooCommerce > Settings > Emails and look for the Customer Invoice option. If it’s enabled, simply disable it to stop invoices from being sent.
If you need further customization, you can modify WooCommerce’s email templates to ensure no invoice-related information is included in the Order Confirmation email.
With these adjustments, customers will continue to receive an Order Confirmation email, but invoices will not be automatically generated or sent through WooCommerce.
