# How to Set Minimum and Maximum Booking Quantities per Service
### Offer More Flexibility While Staying in Control of Your Booking Capacity
This guide explains how to use the **Quantity on service** feature to define how many people or units can be booked for a single time slot. This is especially useful if you offer services like event entries, group experiences, or table reservations where multiple spots can be booked at once.
{% hint style="warning" %}
This feature controls how many spots can be booked in *one time slot*, not multiple time slots. If your service is set to allow 1 booking per time slot, setting a minimum quantity of 2 will cause availability issues.
{% endhint %}
### Enable the Quantity Feature
1. Go to **Apps**
2. Open **Cowlendar**
3. Navigate to **Settings > General Settings**
4. Scroll to the **Quantity on service** section
### Define Quantity Rules for Specific Services
In the **Quantity on service** section, click **Add a service**.
You can choose to:
* Keep the **“All services”** toggle active to create a **general rule** that applies to all your services.
* Or, add **specific rules for individual services** even while the general rule is active.
For each service you configure, set:
* **Minimum quantity** (e.g., 2)
* **Maximum quantity** (e.g., 8)
{% hint style="info" %}
This allows you to force customers to book at least a specific number of seats or slots in a single time slot.
{% endhint %}
### Make Sure Your Booking Limits Match
To ensure the quantity rule works without errors, double-check the following:
1. Go to **My Services** and click **Edit** on the relevant service
2. Open the **Advanced** tab
3. Confirm that **Booking limit per timeslot** is set to a value **equal or greater** than your quantity maximum
* Example: If you allow 8 people per booking, the booking limit per timeslot should be **at least 8**
{% hint style="danger" %}
The quantity selector will still appear, but if your quantity settings don’t match the availability limits of the service, the service will show as **“Availability Not Found”** and your customers won’t be able to complete a booking.
{% endhint %}
