These days where accountants are insisting on a minimum number of quotes are really tough. No longer (in my opinion) can a company buy a maintenance contract and hope to make enough on repairs to be in profit, as very often the profitable repairs have to be multiply quoted and you get screwed again.
And the less scrupulous clients will expect you to match or beat a non-compliant (therefore stupid cheap) quote, knowing your company probably can't afford to argue the toss!

The industry, and any others like it, are deeply, deeply stuffed. Wish I knew who was making the dough, 'cos it's no-one I know!
