Ariba Invoice must be integrated with Ariba Supplier Network (Ariba SN) before you can manually create invoices against a contract (using a process called collaborative invoicing). See the Ariba Invoice Guide for more information.

Suppliers cannot create invoices against purchase orders using a customer's PunchIn site. Suppliers must use Ariba SN to do so.

When a supplier or a customer creates an invoice against a contract, Ariba Invoice automatically sends a copy of the invoice to Ariba SN after the invoice is fully approved. A supplier location must be specified on the invoice and the supplier must have a valid Ariba SN account and Ariba SN ID, or the invoice will not be copied to Ariba SN.

Ariba Buyer must be configured to create receipts against a contract. See the Ariba Contract Compliance Guide for details.

When receiving is enabled in Ariba Buyer:

• Receipts are linked to the contract as part of the default receiving process.
• Ariba Invoice uses three-way matching by default (invoice-contract-receipt).

When creating a contract request (CR), such as a contract that does not require release orders, the requester specifies whether invoices and receipts can be created against the contract. If allowed, then suppliers (using a customer's Ariba Buyer PunchIn site) and customers (using Ariba Buyer directly) who have the appropriate permission can create invoices against the contract. Additionally, customers with the appropriate permission can create receipts for contract items and milestones associated with the contract.

To create an invoice against a contract:

1. Access the contract for which you want to create an invoice.

Suppliers	Log in to Ariba SN and in the Transactions section of the left navigation bar, click Inbox and then click Contracts. In the task list, click Create contract invoices. In the list of customers who have enabled you to access their PunchIn sites, locate the customer for whom you want to create an invoice and click Go. Ariba SN passes your authenticated credentials to the customer's site and opens a new session there. To return to Ariba SN, click Back to Inbox. If your session on Ariba SN has timed out, you can log back in to your account.
Customers	In the Explore section of the Home page, click Contracts to display a list of contracts. Click the ID of the contract for which you want to create an invoice, and then click Invoice.

2. Create an invoice header.
3. Add items from an existing contract to the invoice. You can also add new items, not yet associated with a contract, to some invoices.
4. Review the invoice summary and submit the invoice for approval.

To create receipts for contract items and milestones (customers only):

1. In Receiving, review the contracts or milestones you have permission to receive.
2. Enter the receipt details, including comments for items or milestones you choose to reject.
3. Submit the receipt for approval.
