# Sites

> Locations with lat/long and geofences — circle or polygon.

## What you'll do

Add every yard, plant, and jobsite you dispatch to or from. Each site needs lat/long and a geofence (a virtual boundary that tells Tread when a truck arrives or leaves).

## Before you start

* A list of sites with name, address, and (if known) lat/long.
* Decide whether each site uses a circle or polygon geofence — circles are the default, polygons give tighter accuracy at large or oddly-shaped sites.
* Polygon shape data exported from another system (KML, GeoJSON) if you want to import existing boundaries.

## Walkthrough

<Steps>
  <Step title="Open Sites">
    Click **Create Site**.
  </Step>

  <Step title="Enter the address">
    Type the address. Tread reverse-geocodes it to lat/long and drops a pin on the map. Adjust the pin if the geocoded result is off.
  </Step>

  <Step title="Draw or accept the geofence">
    Tread defaults to a circle around the pin. Resize it if needed. To use a polygon, click **Polygon** and trace the boundary, or import a KML/GeoJSON file from your records.
  </Step>

  <Step title="Tag the site type">
    Mark as Plant, Yard, or Job site, etc. The type drives reporting and dispatch defaults.
  </Step>

  <Step title="Add contacts (optional)">
    Add a name and phone number for anyone at the site dispatchers or drivers may need to reach — a yard foreman, a gate attendant.
  </Step>

  <Step title="Share with connected companies (optional)">
    Toggle **Share with Connected Companies** to let a connected Customer or Vendor view and select this site — useful for a shared yard or a customer-owned pit.
  </Step>

  <Step title="Save and repeat">
    Sites care added once. Job sites can be added on the fly during dispatch — but pre-loading the recurring ones speeds up order entry.
  </Step>
</Steps>

## Verify

**Sites** shows every location with a geofence drawn. Open one — the map shows the pin inside the boundary. You can move the Pin anywhere you need it to be.

## Common mistakes

<Warning>
  **Switching a site's geofence type after go-live.** Changing from circle to polygon (or vice versa) reshapes how Tread interprets historical truck arrivals and exits. Past tickets recompute against the new shape, which can shift on-site times and break reporting. Pick the right type at setup. See [Sites & Geofences](/concepts/sites-geofences).
