My invoice is still stuck in Approved/Sent status and not updated to paid even when buyer has sent the payment.

Your customer has not sent Remittance/Schedule payment information.

Payments are not processed through SAP Business Network, but your customer can upload payment details to your account for you to view.

If your customer chooses to supply it, you can access payment information by going navigating to :

1. Go to Payments

2. Select one of the following menu items:

• Early Payments
• Scheduled payments
• Remittances.

If your customer has not provided scheduled payment or remittance information, the best way to find out when your invoice will be paid is to contact your customer.

Please note that SAP Support cannot provide any information about the payment of your invoice. It is your customer's responsibility to inform you of when you will be paid.
