# Subscription & Billing

### Overview

Suptask billing model is based on Agents which represents a seat in your subscription. 

An Agent is defined as a person who have access, can reply and manage tickets in an Inbox. 

{% hint style="info" %}
Suptask do not charge for your Slack workspace users. Only those users who are identified as Agents. 

**For example**: if you have 400 users in your Slack workspace but only 5 Agents in Suptask, those 5 will be charged for. 
{% endhint %}

***

### How the billing works

Suptask will automatically calculate the number of Agents where we identify all the users who are a part of the **Responder channels** that is connected to your Inbox.

Every user who is a part of a Responder channel in Slack will be an Agent.  

Suptask has a 6 hour grace period before we charge for any newly invited Agent. This allow you to remove any user that was invited by mistake before they are charged for. 

You will be charged for any newly added Agents on the same day. If you remove an Agent, it will be accounted for on your next billing cycle.

{% hint style="info" %}
Agents are unique across Inboxes & Responder channels, which means that an Agent who is a part of two different Inboxes will be calculated as one single agent.
{% endhint %}

***

### Example

 \
You have two Inboxes with separate connect Responder channels in Slack. 

These 2 Inboxes have a total of 10 unique Slack users that have joined the Responder channels. You will then be charged for a total of 10 Agents. \
\
In week 3, there are 5 additional users joining the Responder channels of the Inboxes. You will be charged for an additional 5 Agents.

In week 5 there are 2 users leaving the channels. On your next billing cycle the 2 agents will be deducted for.

***

### Prorated billing

Suptask makes use of prorated billing, which is a method of bill calculation based on a partial period of service rather than a full billing cycle. 

It lets customers pay for the portion of the service period they use and not the entire service period, which makes billing more accurate.

***

### Change the amount of licensed Agents 

In order to change the amount of licensed Agents that you are charged for, you can [remove Agents](/setup-and-configure/inboxes/how-to-use-suptask-inboxes.md#how-to-remove-an-agent) from your Inboxes. This will automatically update the subscription on your account
