# Introduction

> Manage clients, projects, time entries, invoices, and PTO from your terminal.

`neetoinvoice` is the official command line interface for NeetoInvoice. It wraps the same
public REST API documented in the [API reference](/getting-started/introduction), so anything
you can do over HTTP you can do from a shell, a script, or a CI job.

    Sign in once from the browser with `neetoinvoice login`. Credentials are stored on your
    machine and reused by every command.
  </Card>

  <Card title="Built for scripting" icon="terminal">
    Every command speaks JSON on request, and `--quiet` reduces a response to the single
    identifier a shell pipeline needs.

  <Card title="Built for AI assistants" icon="robot">
    `neetoinvoice setup claude` teaches your coding assistant the command surface, and
    `--toon` cuts token use when feeding output back to a model.

  <Card title="Multiple workspaces" icon="layer-group">
    Sign in to as many subdomains as you need and pick one per command with `--subdomain`.
  </Card>

## Prerequisites

* A NeetoInvoice workspace and its [subdomain](/getting-started/workspace-subdomain).

  permits.
