Fair Billing Policy for Invoice-Based Plan 


Chargebee delivers a fair billing policy with transparency and customer-centricity. A fair billing policy enables you to pay only for what you use. The further read will help understand the fair billing concept in detail.


Two terms you will read about constantly in this document. You can read more about them here.

  • Overage amount: In Chargebee, each invoice-based pricing model offers a default invoice limit covered in the base plan amount. When you exceed this limit, you will be charged an overage amount (on top of the basic plan amount) for the additional invoices processed. The overage percentage (%) varies based on your plan. Refer to our pricing  for details on the overage charges associated with each plan.
  • Voided Invoice: It refers to the invoices you void (cancel) in your live Chargebee site.
  • Invoice-based plan: This plan offers a pricing model that is based on the number of invoices your site is generating during monthly, quarterly, half-yearly, yearly, or multi-year billing cycles.

There are two initiatives to ensure a fair and transparent billing policy for customers.

Excluding voided invoices from overage calculation 

Chargebee automatically adjusts overages in the current billing process for monthly, quarterly, half-yearly, and annual subscriptions for all invoices created and voided in the same billing term. For example, if you are billed monthly, the amount of invoices that are created and voided in the same billing term will not be considered. Similarly, if you are billed quarterly, half-yearly, or annually the number of invoices that are created and voided in the same billing term (quarterly, half-yearly, or annual) will not be considered as well. Therefore, it will be excluded from the overage calculation of the corresponding billing term.

During automatically adjusting overages of the monthly subscriptions It is noticed that an invoice created in a month might get voided the next month, but since the renewal cycle is shorter in this case, the amount of the voided invoice(s) has been accounted for the overage calculation of the previous billing term.

For customers with monthly subscriptions, Chargebee issues promotional credits to resolve the issue for the overage amount that is contributed by the voided invoices (of the immediate previous billing term) and automatically applies this on your subsequent invoice.

Prerequisites for promotional credits

The following are the eligibility criteria for promotional credits.

  • Active customers with monthly subscriptions (in the invoice-based model) are eligible.
  • All the invoices generated in the previous month but voided in the next immediate month are considered for promotional credits calculation.
  • If the overages are raised in the previous month, the respective overage amount that accounts for the voided invoices will be provided as promotional credits.

The following are some use cases that explain the logic of promotional credit calculation for an invoice-based plan.

Automatic alerts based on invoice generation 

Chargebee sends three alerts when invoicing limit reaches 50, 80, and 90 percent(%) for customers who have quarterly, half-yearly, yearly, or multi-year billing cycles. This communication will help Chargebee's customers to compare current and projected business growth based on the invoice count. It also reminds customers to connect with their Customer Success Manager (CSM) or Account Manager (AM) for upcoming subscription renewals.

For customers having a monthly billing cycle, a single email alert is generated when the invoicing limit reaches 90 percent(%). This is to avoid multiple email alerts for monthly subscriptions. The alert appears on the application user interface when invoicing limit reaches 50, 80, and 90 percent(%).

  • The alert appears as a banner on the application only for the admin or owner of the site.
  • The fair billing initiatives are not applicable for freemium users.
