# Billing parameters

_How to set the size (weight) and coat ranges the system uses to classify each pet._

Under **Settings → Billing Parameters** you define how the system **classifies each pet** into a **size** and a **coat**. This is the basis of size+coat pricing.

## Size (weight ranges)

For each **size** you set the **weight range** with the slider:
- **Micro**, **Small**, **Medium**, **Big** and **Giant** (e.g. Small from 3kg to 15kg, Medium from 15kg to 30kg…).
- Each size has an **Accepted / Not accepted** switch — turn off a size the store doesn't serve.

The pet's weight (on the [pet record](/en/operacao/clientes-e-pets/cadastrar-e-editar-pet/)) automatically falls into the right size.

## Coat (length)

Below, set the **length** of each **Coat** (Short, Medium, Long — e.g. Short up to 3 fingers). Together with the size, the coat completes the combination used in the [service's price table](/en/configuracao/cadastros/criar-um-servico/).

## Save

Adjust the ranges to fit your business and **save**. Changing a range re-classifies pets — check the price impact first.

> **⚠️ Heads up**
>
> Set the **size ranges** carefully (the weight that separates Small from Medium, etc.): that's what decides the pet's **size** — and, in size+coat mode, the service **price**.

## The role of these parameters by billing mode

### By size & coat
Your store charges **by size & coat**, so these parameters **define the price**: the weight range places the pet in a **Size** and the length sets the **Coat**, and the service table uses that combination.

### By breed
Your store charges **by breed**, so the **price comes from the pet's [breed](/en/configuracao/geral/especies-e-racas/)**. Here the size and coat ranges are only **reference** (a notice at the top reminds you) — they don't set the price directly.
