Zoho Books connects your organisation to Zoho Software Trading LLC, an FTA-accredited Accredited Service Provider (ASP). If your organisation is already registered with another ASP under the same TIN, you must offboard from your existing ASP. You can then register with Zoho’s ASP through Zoho Books to send and receive transactions through Peppol.
