In the first year on our own, I got 90% of the jobs I quoted, and things have steadily declined. Here's my thoughts on reasons
In your first year or so, most of your work comes from people you know, or direct references... so fewer people are quoting against you, Have you asked your clients (in a oppertune situation) how many other companys quoted, or what there prices were.
In my first year I did this when ever I felt I could. It help to set my pricing on the market
Now as we grow our referrals are often second and third hand so we don't know the client as well and there may be many more bids on the job This year I think we might be luck to get 40-50%
I think that's progress though on th per job income, I know I'm not low balling all the time anyway.
