All three are optional — set up only what you'll actually use. ## Where each one applies | Object | Apply it to | Use it for | | --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------- | | Departments | [Projects and Orders](/concepts/orders-projects), [Customers](/onboarding/master-data/customers), [Vendors](/onboarding/master-data/vendors), [Sites](/onboarding/master-data/sites) | Filter the Dispatch board, Projects list, approvals, and reports by division | | Labels | [Users](/onboarding/master-data/users), [Drivers](/onboarding/master-data/drivers), Customers, Vendors, [Equipment](/onboarding/master-data/equipment) | Color-coded chips for filtering and quick identification | | Service Classes | Projects, Orders, [rate cards](/workflows/manage-rates) | Rate and bill by type of service | ## Before you start * A list of departments your business reports against (e.g., Aggregates, Asphalt, Hauling). * A list of dispatch labels you already use on whiteboards or sticky notes (e.g., "Standby," "Priority," "Inbound"). * A list of service classes from your accounting or job-cost system if you code work by job type. ## Walkthrough Settings → **Departments** → **Create Department**. Departments group [orders and projects](/concepts/orders-projects), accounts, and [Sites](/onboarding/master-data/sites) for reporting and filtering — the Dispatch board can filter by department. Use them if your finance team already reports by division. The Create Department dialog with a department name filled in Settings → **Labels** → **Create Label**. Labels are color-coded tags for Users, Drivers, Customers, Vendors, and [Equipment](/onboarding/master-data/equipment). Pick a name and a color — the preview shows the chip drivers and dispatchers will see. Mirror the tags you already use on whiteboards. The Create Label dialog with a name, color choices, and a live preview chip Settings → **Service Classes** → **Create Service Class**. Service classes define the types of hauling service you offer (e.g., Hauling, Plant, Standby) and are used for rating and billing — a [rate card](/workflows/manage-rates) can be narrowed to a specific Service Class. None of these are required. Add only what your team will use day to day. You can come back later. ## Verify Each panel lists the rows you added. Create a test order — the new department and service class show up as options on the order form. ## Common mistakes **Creating a label, department, and service class for every concept.** Pick only what your team will actually use daily and skip the rest.
