As I said, it's not a 'right' it is a decision you have made.
Ok, just a play on words
Nothing personal but I can see no reason whatsoever to show them your prices. None, never, ever, not their darn business.
If I dont want any risk, and want to enjoy my work by working T/M, the customer has to take the risk. By telling him that he has access to the cost invoices, it at least shows him that I have nothing to hide,
Does the grocery store you shop at show you the price they paid?No, I dont have a cost plus agreement with the grocery store, Does the supply house show you what they paid? Same deal, not T/MDoes anyone you do business with show you what they paid for what they are selling you?Yes, I've had cost plus carpentry work done before, and frankly I liked it.
Why would you want to show them your costs? :-?
