Short answer

How do I send a correction letter with my AI?

Tell your AI to issue a CC-e for a specific authorized invoice. It handles the adjustment in Focus Admin, and you'll see the updated status immediately. Here is how the process works.

The results.

Where every correction lands.

Your AI moves every request into one of these four states.

SUCCESS

Correction issued

The AI successfully sends the CC-e. The invoice record in Focus Admin updates to reflect the new totals.

VOID

Correction cancelled

If you need to pull back an adjustment, the AI voids the request. This keeps your billing history accurate.

ERROR

Action failed

If the invoice is locked or missing, the AI tells you exactly why it couldn't complete the request.

MANUAL

Human review needed

When the AI lacks the specific permissions for a high-value correction, it stops and asks you to step in.

The workflow

What your AI does when a mistake is found.

The AI acts as the bridge between your chat and the Focus Admin ledger.

  1. Locate the invoice

    The AI identifies the authorized invoice in Focus Admin to ensure it has the right data for the correction.

    send_cc_e

  2. Submit the CC-e

    The agent sends the formal correction letter to adjust the invoice amounts or details.

    send_cc_e

  3. Verify the change

    The AI confirms the system accepted the correction so you don't have to double-check the logs.

    send_cc_e

  4. Cancel the request

    If the correction was sent in error, the AI can void the CC-e to revert the status.

    cancel_cc_e

FAQ

How this task behaves

  • 01

    Can the AI delete an invoice?

    No. The AI can only issue corrections or cancel a CC-e.

  • 02

    Does the AI have my login credentials?

    No. Vinkius manages the connection so your credentials stay encrypted and away from your AI client.

  • 03

    What if the invoice is already closed?

    The AI cannot issue a correction on a closed invoice. It will notify you that the action is not possible.

  • 04

    Can I undo a correction?

    Yes. You can ask the AI to cancel the CC-e if you need to void the adjustment.

  • 05

    Can the AI change the original invoice directly?

    No. It uses the CC-e tool to issue a correction rather than overwriting the original record.
