   • Refunded – This order status ensures credit note generation for a full refund.
   • Other order statuses (like processing and completed) – A credit note is generated for partial refunds when an order is in one of these selected statuses.
3. Enable the Attach credit note in ‘Refund’ email option to attach a PDF copy of credit notes to refund emails.

After configuring the basic settings for invoice, packing slip, and credit note generation, the system will automatically generate these documents based on the selected order statuses. In this case, “Processing” is set as the order status for auto-generating invoices, packing slips, and credit notes. A customer places an order for a WordPress Tee, and the store owner then updates the order status to “Processing.”

As the order reaches the Processing status, the plugin automatically generates the invoice. A PDF copy is simultaneously attached to the order confirmation email and sent to the customer.

When the order falls into the Processing status, the plugin generates the packing slip. The plugin then attaches the packing slip as a PDF attachment to the order email.

If the store owner processes a partial refund, the system generates a credit note and attaches it as a PDF to the refund email sent to the customer. In the case of a full refund, the order status changes to Refunded, and the system generates a credit note for the full refund.
