Imagine quoting for two separate jobs? One job is located just 2 miles from your operating base and the other job is located 30 miles away.
For the sake of this exercise, let's say that both landscaping projects are exactly the same specification.
How do you apply the pricing formula? should the project of greater distance be priced in the same way as that of a project locally?
There's not only the lost travel time to consider but there's also the, often ignored, cost of travel. Treat the two jobs in the same way and ignore the fuel cost and you will surely be out of pocket on the job further from your operating base.
Working out the cost of travel
It is easy to convert your fuel charges into an overhead cost retrospectively and apply these costs on a day-by-day or a week-by-week basis. However on the occasion you are forced to travel outside of a normal working zone, fuel costs should be treated as a surcharge and not as an overhead.
