# Plans and add-ons

> Squid ID has no plan tiers. Matching is prepaid and usage-based, and the optional add-ons are billed separately from your match credits.

Squid ID has no plan tiers. Matching is prepaid and usage-based, so you only pay for the visitors you reveal. A few optional add-ons sit on top, billed separately from your match credits. You manage all of them under **Settings → Add-ons**.

## The add-ons

Each add-on has its own page with pricing and setup:

* [Squid ID+](/add-ons/squid-id-plus) gives you fuller contact and profile data on each match.
* [Form fill enrichment](/add-ons/form-fill-enrichment) turns the form fills we could not de-anonymize on the visit into full visitor records.
* [Additional domains](/add-ons/additional-domains) let you track up to 3 websites, at \$25/month each beyond the first.
* [API access](/add-ons/api-access) is a read-only REST API as a flat \$19/month add-on.

## How add-ons are billed

* Add-ons are separate from match billing. You pay for them only while they are turned on.
* Enabling an add-on requires a card and takes effect immediately, prorated for the current period.
* Removing a website or disabling an add-on takes effect at the end of your current term. You keep it until then, with no mid-term refund.
* Every add-on is charged to your default card.

## If you're coming from RB2B

<div className="compare">
  <table>
    <thead>
      <tr><th /><th>RB2B</th><th>Squid ID</th></tr>
    </thead>

    <tbody>
      <tr><td>Plans</td><td>Tiered plans with credit overages</td><td>No tiers, prepaid usage-based matching</td></tr>
      <tr><td>Extra websites</td><td>\$99/month per domain</td><td>\$25/month per domain</td></tr>
      <tr><td>API</td><td>Pay-per-credit on a separate invoice</td><td>Flat \$19/month, one invoice</td></tr>
    </tbody>
  </table>
</div>

<p className="why"><strong>Why this matters.</strong> Add-ons are separate from match billing, so you pay for extra websites and API access only if you use them, and removing one never costs you the rest of the term you already paid for.</p>
