# Billing Configuration

> A reusable entity attached to a Pricing Module, governing bill-run timing, dunning, and late payment behavior.

A **Billing Configuration** is a separate entity from the [Pricing Module](/billing/pricing-module) itself—created independently, then attached to it. Required when a module is marked Plan.

Like Rate Cards and Charges Rules, it's reusable: the same Billing Configuration can be attached to multiple Plans rather than creating one fresh per Plan.

<Warning>
  Billing Configuration doesn't have versioning yet either (tracked as a backlog item). Until it ships, editing it, the billing day, a dunning interval, the grace period, affects every Plan it's attached to, and their existing subscribers, instantly.
</Warning>

It has three parts:

## Bill-Run Configuration

* **Billing Cycle** — **Monthly** or **Weekly**.
* **Billing Day** — a number specifying where in that cycle the bill run falls.

## Dunning Configuration

Reminder messages sent at defined intervals on an outstanding receivable.

## Late Payment Configuration

Governs the Late Payment component's grace period and surcharge application.
