Yes, your profit margins are under threat.

Over the last couple of months, we have seen multiple increases in the price of steel, timber, fuel, labour and more.

If you have not increased your prices, you are wearing the cost and you are going to be making less money.

Before you increase your prices , make sure you are communicating the value you offer to your clients well. Exceptionally well.  

Remember, price is what you pay, value is what you get.  Make sure your clients know what they are getting!
