> **Description:** How Unscheduled charges work

# Unscheduled charges

An Unscheduled charge is a payment that happens instantly and is not part of a regular schedule. These are typically ad hoc or "one-off" charges created for an active payment agreement.

## Example industries/use-cases

Unscheduled charges are used in scenarios where payments are not planned ahead or when the total amount depends on certain factors. Here are some common use cases for unscheduled charges:

  On-demand ride services: Charging customers for rides once they are completed, based on distance and time.
 Utility services: Charging for electricity consumption after the usage is determined, such as charging for electric vehicle charging.
🅿 Parking services: Charging based on the duration of stay when a vehicle leaves a parking facility.
 Subscription overages: Billing for overages in cloud storage or data usage beyond the subscription limit.

## Key features

###  No retries

If the charge fails, it does not retry automatically.

###  Lower conversion

Charge success rate is **80% or lower**. This is because there are no retries and no overview for users in the app in advance.

###  User experience

1. No Overview: Users do not see upcoming charges in their app in advance.
2. No Management: Users cannot proactively manage payment sources before the charge processing. Although they can manage payment methods from the agreement, they have to remember the charging cycle and do it by themselves without the app aiding them.

###  No bulk charging

Not supported for unscheduled charges.

###  Rate limits

Up to 500 requests per minute.

###  Lead time

The charge is created ad-hoc by the merchant and processed as early as possible.
