Tiered Pricing

Updated June 07, 2016

Tiered Pricing is a means of providing products or services at different price points. In this type of pricing model, the product rates are bundled into separate pricing tiers. Once a tier is filled up, the product will move to the next tier and a different price will be charged.

If you're looking to set up Volume Pricing, please refer to our guide here.

Use Case 1: Subscription created with 10 units

When a Subscription is created with a quantity of 10 units, all units will be charged $15, as the number of units would fall in the Tier 1 range.

Use Case 2: Subscriptions created with 50 units

When a Subscription is created with a quantity of 50 units, the price would be calculated across all four tiers.

Set up

Here's a quick guide on how to set up Tiered Pricing using API and JSON payload.

Step 1

Create a $0 Base Plan (e.g. Plan name Cloud Server) with Flat Fee pricing in your Chargebee site. The only purpose of this Plan would be to define the billing frequency of the product (monthly, quarterly, etc.).

cloud_server_base Cloud Server (Base) $0.00

Step 2

Create a Recurring Addon (quantity based) for every tier as shown below. Ensure that the Addon frequency matches the frequency of the Plan.

cloud_server_01_20 Cloud Server (01 to 20) $15.00
cloud_server_21_25 Cloud Server (21 to 25) $10.00
cloud_server_26_30 Cloud Server (26 to 30) $8.00
cloud_server_31 Cloud Server (31+) $5.00

Step 3

Add the JSON Meta data to the $0 Base Plan. Chargebee has the Meta data feature that can be used to store additional data at different levels (Plans, Subscriptions, Customers etc). Add JSON Meta data to the $0 Base Plan, to establish a relationship between "the unit range and the Addons.

Step 4

Create a Subscription with the Tiered Plan and Addons

Based on the Plan's metadata, pick the appropriate Addon(s) and create the Subscription with the required range. The Plan's metadata can be queried before Subscription creation to receive the Addon and Tier details.

How to change quantity for Subscriptions with Tiered Pricing

When a Subscription's quantity has to be changed, you can create the new set of Addons using the Update Subscription API.

Let's consider the following scenario:

A Subscription is created with a quantity of 25 units. The price for this, hence, will be calculated using 2 tiers.

1-20 Units Tier 1
21-25 Units Tier 2

The Customer now wants the Subscription's quantity to be changed from
25 to 5 units.

In this case, call the Update a Subscription API with replace_addon_list parameter set to true and pass the Addon quantities as per the change in Subscription.
