# Adding a purchase order
<a name="adding-po"></a>

You can use the Billing and Cost Management console to add purchase orders to use in your invoices. Adding a purchase order is a two-step process involving purchase orders and line item configurations. First, you enter your purchase order details (for example, purchase order ID, shipping address, effective and expiration month). Then, you define the purchase order line item configurations that are used to match the purchase order with an invoice. If you add multiple purchase orders, we use the purchase order that has the line item best matching the invoice being generated.<a name="add-po-steps"></a>

**To add a purchase order**

1. Sign in to the AWS Management Console and open the AWS Billing and Cost Management console at [https://console.aws.amazon.com/costmanagement/](https://console.aws.amazon.com/costmanagement/).

   If you use billing transfer, sign in to your bill transfer account to add a purchase order number to invoices. You can assign one purchase order number to all AWS invoices from organizations that transfer their bills to you.

1. In the navigation pane, choose **Purchase orders**.

1. Choose **Add purchase order**.

1. For **Purchase order ID**, enter a unique identifier for your purchase order ID. Purchase order IDs must be unique within your account. For details about character restrictions for your purchase ID, see [Purchase orders](billing-limits.md#limits-po).

1. (Optional) For **Description**, describe your purchase order, including any notes for your reference.

1. For **Bill from**, choose the AWS billing entity that you are invoiced from.
**Note**  
Remittance details are different for each **Bill from** location. Be sure to verify your **Bill from** selection. You must make your payments to the legal entity that you're billed from. We don't recommend configuring more than one **Bill from** location for a purchase order.

1. (Optional) If your purchase order is invoiced from the **Amazon Web Services EMEA SARL** billing entity: For **Tax registration number**, select the tax registration numbers that you want to associate with your purchase order. Your purchase order is associated with only the invoices generated for the tax registration numbers that you select.
**Note**  
The **Tax registration number** selection is available for only the **Amazon Web Services EMEA SARL** billing entity. For more information on your tax registration number settings, see [Setting up your tax information](manage-account-payment.md).

   (Optional) Select **Copy Bill to address** to copy and edit the address populated from your **Bill to** field.

1. For **Effective month**, choose the billing period when you want your purchase order to start. Your purchase order is eligible for invoices that are associated with usage, starting from the billing period that you specify.

1. For **Expiration month**, choose the billing period when you want your purchase order to end. Your purchase order expires at the end of the specified billing period. It's not used for invoices that are associated with usage after the billing period.
