Billing & Costs

When reviewing tickets, you can click on them to see billing/cost breakdowns such as the ticket below:

The three categories are:

1. Haul - The price/cost of delivering a material/service
2. Service - The price/cost of the actual material/service
3. Overhead - The estimated administrative cost associated with fulfilling the ticket

Billing

The information under billing comes directly from Interact, and is therefore not an estimate but the actual cost to the client.

Costs

Unlike billing, the only number that is not estimated on the costs side is the Haul. The haul is the actual amount paid to the truck that fulfilled the ticket.

Service

The service cost is calculated as follows:

First, GPA tries to find the cost of the material at the specified location on the ticket date.

For the ticket above it would look for the price of CR-6 at Savage Stone on August 18, 2025.

Tip

You can view what reference cost the program is using by hovering over the service cost. Eg.

If the reference price is not found, the ticket will be flagged with the Unknown Cost flag.

In this case, as we can see above the price is $14/ton.

Then we can simply multiply by the tonnage:

$$Cost\times Quantity=Est.ServiceCost$$ $$14\times 18.61=260.54$$

Note

The numbers visible to the users are always rounded, so calculating things manually will usually be slightly off.

Sometimes the COST UNIT will vary from the TICKET UNIT. While GPA handles the conversion automatically, some additional conversion will be necessary for manual verification.

Overhead

At this time, overhead is a flat multiplier by the total billing on a ticket.

Currently this is 24% of the total billing. For the above ticket it is as follows:

$$(Haul+Service)\times 24\%=Overhead$$ $$(0+664)\times 24\%=159.36$$

Net

Net is simply the difference between billing and costs.

$$Billing-Costs=Net$$ $$664-565=99$$
