There are a few primary reasons you see bids on the same job being so far apart. Maybe not 50 to 15 as reported in a lower post, but I can get a quote for mow/blow everyday for half the highest quote. Companies that spend the time and effort to bid the job often loose it to someone who leaves quite a bit of money on the table. Why is this? In my 30+ years of experience in the green industry it all boils down to this; companies or individuals not knowing their true costs (overhead) and the same not having enough business experience, knowledge or training to bid it correctly. If you feel you are in this group and want to improve you business skills here are a few tips. 1. Take an adult education business class. 2. Join a green industy group and attend meetings to discuss issues related to what we do. PS There is nothing like sharing ideas with someone who has been there, done that. 3. Be diligent about tracking your expenses and KNOW WHAT YOUR OVERHEAD IS BY GETTING A PROFIT/LOSS STATEMENT PER MONTH OR QUARTER. Make sure you understanding it and know what profit is. 3. Understand as your company grows your role and job description changes. 4. Subscribe to industry books and read articles to improve your knowledge. Now...if your sitting there reading this post and saying to yourself....."I don't have time for that" realize this.... If you don't take the time to improve your business skills you are only hurting yourself and the whole industry you are working in.
