# Assignments

An Assignment is a **managerial bundle** created by a workplace or agency to configure work for a group of senders.

## What's Inside an Assignment

The assignment brings together everything needed to manage contractor work:

* **Senders** — Who is working (contractors, freelancers)
* **Approvers & Processors** — Which Teams will review and process timesheets
* **Billing Plan** — A reusable template defining how timesheets are structured (time units, tier grid per weekday)
* **Rate Plans** — Per-sender payment tables that reference the billing plan (what each sender gets paid at each tier)
* **Activities** — Preset work categories that appear in senders' journal
* **Client Link** — Who the assignment is for
* **Invoicing Configuration** — How invoices are generated (PDF or accounting provider sync)

## Assignment → Workflow

When an assignment is created, it automatically generates an **Assignment Workflow**—a read-only workflow that senders see. This workflow shows them:

* The approval path their timesheets will take
* Who will review their work
* Invoicing details

Senders cannot modify the assignment workflow; it's defined by the workplace/agency.
