# Add Attachments - Old DPO Design

Attachments can be added to an invoice at any time, regardless of the invoice status, whether it is Pending, Fully Approved, Matched, or Unmatched. 

||| **Already using DPO's new design?** [You can find the corresponding article here](https://help.digitalpurchaseorder.com/en/article/add-attachments-to-an-invoice-o80z84/)

### How to add attachments to an invoice

The attachment feature allows you to add supporting files directly to an invoice for easy reference. From the invoice screen, you can open the **Add Attachments** option using the paperclip icon in the top-right corner. This opens the **Manage Attachments** window, where you can upload files from your device and save them to the invoice, ensuring all related documentation is stored in one place.

| Attachments can include contracts, receipts, shipping documents, corrected invoices, and other supporting files. There is no restriction based on the invoice status.
