Contractors: which line item do you most often forget to charge for?

ScopeBid launches here on November 1. It's a quoting app for owner-operated trades: painters, cleaners, landscapers, handymen and detailers.

The idea is to quote the next job from what past jobs really cost. You start from a saved job, a trade template or a blank quote, and before you send it, Profit Guard shows the customer price, direct cost, estimated gross profit, gross margin and markup side by side. Approved quotes turn into invoices without retyping, and change orders show their own profit impact. It works offline.

A question for anyone who quotes jobs: which item slips off your quotes most often? Trip charges, disposal, prep time, materials markup, the second coat? Which ones would be worth a reminder before you hit send?
