Nice post Stevie, I have been thinking about this today, whilst you obviously want to run your business in a way that works for you, you have to step back once in a while and look at wether it really is working! I don't just mean making money, are you happy, stimulated, do you get up each day looking forward to the work ahead of you?
However my comments on this thread are based on a fairly simple principle: however thrifty and well organised you are you can only get your overheads down so far, the cost of the kit we all buy and the consumables we all use are pretty standard across the whole country. You may only work local, and save money in all sorts of ways, but fuel is near enough £1.40 a litre wherever you are. I chose £80k as a turnover because I think after deducting an average amount of overheads that is a figure that ought to give you a reasonable profit / wage. You may do well turning 60k or you may need 90, but chances are the higher your turnover the more you will make.
Consider this: 2 arb teams both working in the same radius using a transit and 6" chipper, both pay the same wages and have similar overheads. Team A charges 350 a day for 200 days and turns £70k, team b charges 400 a day for 200 days and turns £80k. Given that their costs are the same team B has made a whole £10k more by just charging an extra £50 each day. In reality we will all have different overheads, (mine are £1800ish a week BTW) however adding a small amount to your turnover without increasing your overheads too much is the way to make money. So those who say turnover is vanity, think again, if someone else with similar kit and staff numbers like yours turns more, he probably makes more too.
One final tip. Don't work on a day rate. I hear you saying " I never do, I always price each job individually" thats fine but I used to find that I would look at a job and say " thats about a day" and stick what was effectively a day rate on it. Or a half day, or two days, I reckon we all tend to do this ( look at your invoices over the years, are they all different amounts? or lots of multiples of the same figure... your day rate:sneaky2:...) and there's nothing wrong with pricing that way, but what happens when you get one thats a bit more than a day but not 2 or 3/4 of a day? The best way to work is to have a rigid weekly target that you aim to hit every week, forget about having a day rate, and price each job as it looks, considering your competitors and what you think they will want for the job. This way you may find a job where for example you know it suits your setup perfectly and the the competition may struggle a little, think what they will charge and aim to beat that, it doesn't matter if you can do it in 2 hours because of your crane / climbing groundy / mini loader or whatever your "edge" is. You charge what you need to just beat the competition and no less. This means that on that day you made extra, more than your "day rate", you can now afford to go cheap the next day in order to win a job you know will be up against cheap competition. So long as you make your weekly target it doesn't matter if you do one job for £150 so long as you got in a £750 or whatever.
Set your self a challenging but achievable weekly target and go for it for 6 months, see what happens. My business has really taken off since I started doing this. Give it a try.
