# Create a purchase order

> Place an order with a supplier in ION, add lines and parts, and reuse common orders with templates.

## Create a purchase order

1. In ION, go to the **Purchases** page.
2. Click **Create Purchase Order**. ION creates the purchase order and opens its detail page.
3. Set the supplier on the purchase order using the **Supplier** field.
4. Add lines to the order. For each line, set the part, quantity, cost, and any other details for the purchase.
5. Optional: set a quality clause or term requirement on a line so the supplier delivers against it. See [Manage requirements](/administration/supply-chain-settings/manage-requirements).

To buy a good or service you don't track in inventory, leave the **Part** field empty on the line, or pick a part whose purchase type doesn't create inventory. See [Purchase types](/manage-supply-chain/purchasing/overview#purchase-types).

You can print a draft PO at any time. The draft watermark is removed once the PO moves past the ordered state.

## Set an external reference

Set the **External Reference** field in the purchase order's **Purchase Order Information** section to link the PO to an identifier from another system, such as an ERP PO number.

## Reuse an order with a template

Use the external reference to create purchase templates for common orders, then copy a template to start a new purchase instead of building it line by line. For a walkthrough, see this [video on purchase templates](https://www.loom.com/share/6d20821c431e42aaa2e13387807c0e94?sid=bac5b73f-b3d5-4dcf-a9ec-7246f6dafd04).
