# Invoices

> Find and download invoices for your Eva AI subscription.

If you need a tax invoice (CFDI) for what you pay for Eva, you turn it on once and it's generated with every charge from then on. You set it up in **Settings → Subscription**, in the subscription billing section.

## Turn on your invoice

<Steps>
  <Step title="Choose to receive an invoice">
    In the subscription billing section, select **Yes, generate factura**.
  </Step>

  <Step title="Complete your tax details">
    Upload your **Constancia de situación fiscal** and Eva fills in your RFC, legal name, tax regime, and postal code for you. You can also enter them by hand.
  </Step>

  <Step title="Say who should receive it">
    Add the emails that should get the invoice (up to five).
  </Step>
</Steps>

<Note>
  The invoice applies **from the moment you turn it on**; earlier charges aren't invoiced automatically. Turn it on before your next payment so you don't miss it.
</Note>

## Find your invoices

After each payment, your most recent invoice appears in the history in that same section, along with prior months'. From there you can download the **PDF** and the **XML** (the two CFDI files).

<Warning>
  If your tax details are incomplete, the payment still goes through, but the invoice stays pending until you fix the information. Check that your RFC and constancia are up to date.
</Warning>

<Tip>
  Did a tax detail change? Update it in the same section so your next invoices come out correct. If something doesn't add up, [get in touch](/en/help/contact).
