# Logistics Page

> Shipment costs, travel time, delivery, cancellation, and route margin.

Logistics moves goods between regions and helps compare route economics.

## Main Sections

* Create Shipment
* Route Margin Analysis
* In Transit
* Delivered / Cancelled history

## Shipment Creation Rules

* Destination must be a different region.
* Quantity must be a positive integer.
* Source inventory must have enough available units.
* Company must have enough available cash for shipment fee.

Fee model:

* `fee = base fee + (per-unit fee * quantity)`
* Default values are 250 cents base and 15 cents per unit.

Travel times:

* Core to Industrial: 5 weeks
* Frontier to Industrial: 7 weeks
* Core to Frontier: 10 weeks

## What Happens On Create

* Quantity is removed from source-region inventory immediately.
* Shipment fee is charged immediately.
* Shipment enters `In transit` with an ETA week.

## Delivery and Cancel

* Delivery occurs automatically once ETA week is reached.
* On delivery, units are added to destination-region inventory.
* Canceling an in-transit shipment returns goods to source region.

Cancellation returns goods, but shipment fee is still a sunk cost.

## Route Margin Analysis

The panel compares recent market prices by region for selected item.

* Unit spread = destination last price - source last price
* Net route spread = `(unit spread * quantity) - estimated shipment fee`

This is an estimate, not a guaranteed realized profit.
