# Group Support Ratios on Invoices

> How the billing ratio for group supports appears on generated invoices.

## Overview

When a support is delivered to a group of Participants, the cost of the support is split between them using a billing ratio (for example, `1:3` for one Support Worker to three Participants). Invoices now show this ratio directly on the affected line item, so Participants and Plan Managers can see how a shared support was split.

The ratio appears as a **Ratio** line directly under the support item name:

![A Tax Invoice with a highlighted Ratio of 1:3 in a line item's details, under the support item name and above the Claim Type.](https://docs.astalty.com.au/assets/invoice-group-support-ratio.png)

## When the ratio appears

The ratio line is automatic - there is no setting to switch on, and it applies to invoices as they are generated.

It only appears for group supports where the ratio is **not** 1:1. Ordinary 1:1 (direct) supports don't have a shared ratio, so their invoices look exactly as before.

The displayed ratio always matches what was actually charged for that line - including any [manual ratio overrides](https://docs.astalty.com.au/guide/scheduling/adding-shifts/adding-a-group-shift) applied to the Group Support or to an individual Participant.

A Charge Item marked **Priced at a shared rate** does not use the Group Support's automatic ratio because its price already represents one Participant's share. A ratio still appears when one was set by hand, and it reduces the shared price again.

> Ratios are calculated and adjusted on the Group Support itself. To learn how automatic ratios are worked out and how to override them, see [Adding a Group Shift](https://docs.astalty.com.au/guide/scheduling/adding-shifts/adding-a-group-shift).

> This page covers the ratio on an invoice, which reflects the support as it was actually delivered. To show a Participant their reduced rate up-front - in their Budget and on the Schedule of Supports in their Service Agreement - set a [support ratio on the budget item](https://docs.astalty.com.au/guide/participants/budgets#support-ratios).
