If you've chosen the All-Employee pricing model for Zoho One, rather than the Flexible User model, there's a specific employee count and audit obligation worth understanding under Zoho's Terms and Conditions.
The All-Employee model offers a reduced per-user rate specifically in exchange for licensing every employee in your organisation, not a subset. Because of this, Zoho's terms require you to accurately report your total employee count at the time of subscribing, based on an official statement such as a payroll or tax filing document that discloses your true employee headcount, rather than an estimate.
As your organisation grows during the subscription period, you're required to purchase additional licences for each new employee joining, keeping your total licence count aligned with your actual headcount throughout.
Upon request, you agree to certify in writing that you've obtained licences for every employee in your organisation. Zoho also reserves the right to audit the government-filed statement disclosing your total employee count, to confirm compliance with this requirement. Such an audit, whether conducted by Zoho directly or an independent auditing firm, takes place at your premises during normal business hours, with at least fifteen days' written notice given beforehand. If the audit identifies a shortfall in your licence count, you're required to promptly take corrective action to fix it.
