# How do I update KBO as the primary scheme for E-Invoicing?

Belgian organizations are required to have KBO as the primary scheme for e-invoicing. Using VAT as the primary scheme can cause failures when sending and receiving invoices through Peppol.

**Note:**

*   If E-Invoicing is already enabled, you’ll need to disable it in Zoho Billing first and then enable it again to update KBO as the primary scheme.
*   After you disable E-Invoicing in Zoho Billing, it may take up to 72 hours for the change to reflect in Peppol. We recommend waiting until E-Invoicing is disabled in Peppol before enabling it in Zoho Billing again.

Here’s how to update KBO as the primary scheme:

*   Go to _Settings_.
*   Select **E-Invoicing** under _Taxes & Compliance_ in the _Organization Settings_ pane.
*   Click **Disable** at the top-right corner, if you have already enabled E-Invoicing.
*   Once E-Invoicing is disabled in Peppol, click **Configure E-Invoicing** to enable it again.
*   Enter the necessary details under _Organization Details_ and _Tax Settings_.
*   Under _Scheme_, select **KBO & VAT** from the dropdown.
*   Enter your KBO Number in the _Registration Number_ field.
*   Click **Finish**.
