Subject: Missing Line on Invoice

Dear [Manager's Name],

I hope this email finds you well. I wanted to bring to your attention that there was a mistake on the recent invoice that was sent out. One line item was inadvertently left off the invoice, but I want to assure you that we have the physical stock on hand and the purchase order for that item has been closed.

I apologize for any confusion this may have caused and I wanted to make sure you were aware of the situation. Please let me know if there is anything else I can do to rectify this error.

Thank you for your understanding.

Best regards,
[Your Name]

I'm writing to inform you of an error on the recent invoice [invoice number]. Unfortunately, I neglected to include a line item for [item name].

We do have the physical stock for this item and the purchase order has already been closed. The amount of the missing line item is [amount].

I apologize for this oversight and any inconvenience it may have caused. I have already made the correction in our system and will ensure that this is reflected on the next invoice.

Would you please advise me on how to proceed with this matter? I am happy to provide any additional information or documentation that you may need.

Thank you for your understanding.

Sincerely,
[Your name]
