# Billing

> How hellenicAI billing works — plans, usage, invoicing, and payment.

hellenicAI is billed on a monthly retainer basis, scoped to the services you have active. There are no hidden usage fees, no per-seat charges, and no surprise invoices.

## Common billing questions

<AccordionGroup>
  <Accordion title="Can I change my plan mid-month?">
    Yes. Adding services is effective from the date of activation, billed pro-rata. Removing services takes effect at the end of the current billing cycle.
  </Accordion>

  <Accordion title="What happens if I exceed my usage allowance?">
    We notify you before you reach your threshold — not after. Overage is billed at pre-agreed rates at the end of the cycle.
  </Accordion>

  <Accordion title="How do I cancel?">
    Email your account manager or [support@hellenicai.com](mailto:support@hellenicai.com). Services remain active until the end of the current billing period. No cancellation fees.
