# Distance travelled overages

Loopit has the capability to charge overages for each booking.  For overages to be calculated a tracking device must be attached to a vehicle and successfully taking readings.

### How are overages calculated and billed?

If a booking has overages it is added to the *next* recurring invoice.  For example if a booking has weekly billing:

* Invoice for 1st July to 7th July
  * Customers allowance is 100km for the week
  * During this period the customer travels 110km
* Invoice from 8th July to 14th July
  * This invoice will include the charge for the 10km overages from the previous period.

Note only readings from a telematic device are used for calculating overages
{% endhint %}

### How are swaps handled?

If a vehicle is swapped during a booking the usage allowance will be pro-rated for any partial billing periods.  For example if a booking has 100km weekly allowance, the billing cycle is weekly and the customer swaps on day 5 of the weekly period a pro rata of (100km / 7 days \* 3 days remaining) will be added.

Any usage calculations require at least 2 readings from the same vehicle and same telematic device serial number.  This means when a swap occurs the new vehicle must have a valid reading for the usage to start calculating.

### How do I see the usage in realtime?

An overview of the usages is available on the booking overview on the left side, this is for the current period.
