{% endhint %}

### Billing for PAAY <a href="#paayplugin-billingforthepaayplugin" id="paayplugin-billingforthepaayplugin"></a>

The PAAY service is billed monthly at the time of your CRM subscription billing based on your plugin transaction rate (**RatePerTransaction**) per 3DS authentication attempt.  If using the [PAAY 3RI plugin](/crm/plugins/authentication/paay-3ri.md) then the billing for PAAY and PAAY 3RI are separate.

The current upcoming amount can be found in the Add-ons section on your Subscription page.

{% hint style="info" %}
A non-Dummy Gateway MID with filled in **MID #** and **Processor** fields is required for adding the PAAY plugin. You can go to **Gateways → Gateway List** to create a new gateway or to edit and update these fields on an existing one.

#### Rebills <a href="#paayplugin-rebills" id="paayplugin-rebills"></a>

Rebill authentication can be performed using the [PAAY 3RI plugin](/crm/plugins/authentication/paay-3ri.md).

#### Trial Authentications <a href="#paayplugin-trialauthentications" id="paayplugin-trialauthentications"></a>

For trials, we recommend following these practices:

* **Hold Trial Charge** - Authenticate the cycle 2 transaction amount and send as the initial authentication amount. Do not attempt a PAAY rebill authentication.
* **Full Authorize & Void** and **Validate Card** Trials or any trial with either no cycle 1 price or only shipping for cycle 1 - Run the PAAY authentication using the cycle 2 transaction amount and then send to Konnektive as rebill 3DS parameters.
