# How do I know which type of invoice to create?

## Symptom

How do I know which type of invoice to create?

## Resolution

There are three different avenues you can use to submit invoices to your customer through SAP Business Network. View each of the following invoice type to determine which one meets your needs:

**PO Invoice**  
Create a [PO-based Invoice](https://support.ariba.com/item/view/174981) if your customer sent you a purchase order (PO):

1. Go to the **Workbench** tab at the top of the page.
2. Select **Orders** to view all orders.
3. Click the PO number you want to invoice.
4. Click **Create Invoice > Standard Invoice.**

**Non-PO Invoice  
**Create a [non-PO Invoice](https://support.ariba.com/item/view/174949) if there is no PO in your account, and you do not have a Contract number from your customer:

1. Click **Create** > **Non-PO Invoice** from the upper-right of the home page.
2. Select your customer from the pull-down list (If a customer does not appear in the list, they either do not accept this type of invoice or you need to [request a trading relationship](https://support.ariba.com/item/view/152825) with the customer).
3. Select **Standard Invoice** and click **Next**.

Make sure you have a sales or work order number from your customer to enter on the invoice.

**Contract Invoice**

Create a [contract-based Invoice](https://support.ariba.com/item/view/175148) if you have a contract number from your customer:

1. Click **Create** > **Contract Invoice** from the upper-right of the home page.
2. Select the radio button next to your customer (only customers who accept contract invoices appear on this page).
3. Click **Next**.
4. On the invoice, click **Select** next to **Contract** to select the contract you want to invoice.

If you do not see the option to create a contract invoice, your customers have not sent any contracts to the account you are currently using.
