Bookkeeping and financials for a remodeling or general contracting business
Marketing decisions without job costing are guesses. If you cannot say what a kitchen actually cost you last quarter, you cannot say whether a $500 lead is expensive or cheap, and you will cut the campaign that was making money because the invoice arrived on a slow week.
Contractor books have specific problems: deposits sitting in revenue before the work is done, retainage nobody tracks, subs paid out of the same bucket as materials, and change orders that never make it back to the estimate. The mistake is a bookkeeper who has never seen a draw schedule and files everything as "job supplies", which produces a clean-looking profit and loss that tells you nothing about which room type actually pays.
Two weeks in, working looks like last month closed, jobs costed individually, and a gross margin per project type you can point at. That is what lets you decide whether to run more bathroom ads or fewer.
