# FAQ

> Common questions about cost and billing on the Enterprise plan

<AccordionGroup>
  <Accordion title="Am I billed for an instance I created and did not connect?" icon="circle-question">
    No. Billing only starts counting from the **first connection** of a WhatsApp on the instance. An instance created and never connected produces no cost and does not consume the trial.
  </Accordion>

  <Accordion title="What happens at the end of the trial?" icon="hourglass-end">
    The instance becomes billable **automatically**, with nothing for you to do. At the moment of the switch, the API emits the `enterprise.instance.billable` event with `reason: trial_converted`. About 24 hours earlier, you receive `enterprise.trial.ending` so you can warn your customer.
  </Accordion>

  <Accordion title="Can I skip the trial and bill right away?" icon="forward">
    Yes. Call [`PATCH /api/instance/billing/:instance`](/en/enterprise/billing-control) with `{"billingMode": "billable"}`. The instance starts being billed from that point, with no free days.
  </Accordion>

  <Accordion title="Can the same number trial again?" icon="rotate">
    The trial is granted **once per number**. A number that already trialed goes straight to billing when it connects again, without blocking instance creation. The waiting period to trial again, if any, depends on your contract.
  </Accordion>

  <Accordion title="What is the invoice like?" icon="file-invoice-dollar">
    One invoice **per month**, summing the usage of all your instances. You pay at least your plan's monthly credit, and you pay for the usage when it exceeds that credit. See [How billing works](/en/enterprise/how-billing-works).
  </Accordion>

  <Accordion title="What if an instance only became billable mid-cycle?" icon="calendar-day">
    It commits the amount proportional to the days remaining until renewal. An instance that became billable on the 20th of a 30-day cycle commits about 10 days, not the full cycle.
  </Accordion>

  <Accordion title="What if I delete or log out an instance mid-cycle?" icon="trash">
    That instance's committed amount is **not** refunded, it runs until renewal. Deleting frees the slot to create another instance, but does not reduce the current cycle's invoice. See [How billing works](/en/enterprise/how-billing-works).
  </Accordion>
