at the end of the day you know how much it costs to run your vehicle, or how much a vehicle with operatives costs if out on the road.
obviously its not worth working for a loss, therefore you make a commercial decision about whether you will do a job or not.
if the days work will cover the fixed costs then the next job may make more profit.
i tenfd to quote and then stick to the price, its all too eas for cleaints to say that MATEY DOWN THE ROAD QUOTED A CHEAPER PRICE.
we are all trying to make a profit, therefore we need to be driving prices up for a professional service NOT DOWN, for a cheap service.
most customers appreciate VALUE for MONEY, thats totally different to CHEAP
