# If I have already invoiced my purchase order once, how do I invoice for the remaining amount?

## Symptom

If I have already invoiced my purchase order once, how do I invoice for the remaining amount?

## Cause

Line items that have already been fully or partially invoiced are excluded from the invoice by default. The system prevents duplicate invoicing unless you manually include them again.

## Resolution

To invoice the remaining amount, manually include the previously invoiced line items:

1. Open the purchase order, click **Create Invoice** > **Standard Invoice**.
2. On the invoice page, locate the **Include** column.
3. Review the line items:
   - Line items already invoiced (partially or fully) show a gray toggle(![](https://knowledge.ariba.com/images_RTE/15597456d9ce5f403f6blobid0.png)).
   - These items are not included by default.
4. Click the gray toggle(![](https://knowledge.ariba.com/images_RTE/15597456d9ce5f403f6blobid0.png)) to include the line item (it turns green(![](https://knowledge.ariba.com/images_RTE/15597456d9ce7b94152blobid1.png))).
5. Update the following fields as needed:
   - **Quantity**
   - **Unit Price**
6. Review the totals and click **Next** > **Submit.**

## See Also

- Each of your customers might have different invoicing rules. Some customers only let you edit the **Quantity** and not the **Unit Price**.
- If you receive the error: Quantity exceeds the quantity limit! when trying to update the quantity on an invoice, see [Why do I receive the error: Quantity exceeds the quantity limit! when trying to update the quantity on an invoice?](https://support.ariba.com/item/view/KB0395280)
