# Link Purchase Order (P.O.) to Invoice - Old DPO Design

The **P.O. Matching View** allows users to initiate the invoice linking process directly from the purchase order side. This method works in the same way as linking from the invoice view but starts with the P.O.

||| **Already using DPO's new design?** [You can find the corresponding article here](https://help.digitalpurchaseorder.com/en/article/link-purchase-order-po-to-invoice-in-dpo-12sz9n2/)

###### Good to Know
* The system automatically suggests the most relevant invoices based on their content. However, suggestions can always be reviewed and adjusted manually
* Multiple invoices can be linked to a single P.O. item, for example, in the case of partial deliveries.
* Before confirming the linkage, net amounts, account codes, and department assignments should be carefully reviewed

### How to link a P.O. to an invoice

1. Go to **Invoices → Matching Screen** and switch the view from **Invoice** to **P.O.**
2. Select the relevant **P.O.**; suggested invoice matches will appear on the right.
3. Click the **link icon** next to the correct invoice and select **Link Invoice to Item** to complete the match

4. In the linking window (**Step 2/2**), you can:
* Edit the item name
* Assign or confirm the department
* Review or update the Chart of Accounts
* Finalize the link

5. Click **“Link Invoice to Item”** or **“Link Invoices and Close P.O. Item”** if the invoice fully covers and closes the P.O. item.

6. The final step is to **send the invoice into the approval process.** Depending on your settings, this happens in one of two ways:

* With an **automatic approval process,** fully linked invoices are **automatically** transferred into the approval workflow. No further action is required.
* With a **manual approval process,** each invoice must be sent **individually**. Use the filter view to display only fully linked invoices, open the relevant invoice, and click **“Send for approval.”**

Once sent, the invoice enters the approval workflow and follows the defined approval chain.
