I screwed up pretty bad. I under bid two next door residential accounts. I estimated 28 on each when it should have been around 32 or 33 for each. No surprise, I got the job. What do I do? There is no contract and I have just started. Can I tell them I screwed up? I know it is just five bucks but I could be somewhere else making that five bucks then losing it there! What do I do? Has this ever happened to you? What did you do?
