# How do I associate invoices with sales order?

**Prerequisites** Before associating invoices with sales orders, ensure that:

*   The **Order Number** field of the invoice has the sales order number specified.
*   **Item Name** in the sales order and the invoice are the same.
*   **Items** involved in the invoice are the same as in the sales order(if the item quantity exceeds the prescribed quantity in sales order, an error will be thrown).
*   The invoice selected has the same **Customer Name** as the sales order.

To associate invoices with sales orders:

*   Go to the _Sales_ module on the left sidebar and select **Invoices**.
*   Select the invoices that you want to associate with sales orders.
*   Click the **Associate With Sales Orders** button at the top and and link the invoice to the existing sales order.

The invoices will be associated with the sales orders whose order numbers are specified in the respective invoice, and the status of the associated sales orders will be changed to _Closed_. You can view the details of the associated sales orders in the _Associated Sales Orders_ section of the invoice’s Details page.
