# Use purchase order flow

Place an order using catalog products, and collect the payment using the Purchase Order flow.

## Requirements

Purchase order flow needs to be enabled on your account. Contact 2Checkout for activation.

You have to send the `InternalPONumber` and `AutoApprove` parameters to place a Purchase Order. The company name is **mandatory** when placing an order via PO.

## Currency support

Check with 2Checkout support for a list of currencies available for Purchase Order.

## Workflow

1. The customer is placing the order using Purchase Order as the ordering flow, filling in the internal PO number as mandatory information.
2. You are able to set the order to auto-approve as soon as the purchase order is submitted. Otherwise, you have to approve/cancel it manually from Control Panel.
3. After the order is placed, the order confirmation e-mail is sent, including the payment instructions and payment terms agreed.
4. The order is finalized as soon as the payment is confirmed.
5. If payment is not received according to the terms, the order is canceled.
