Almost everything written about technology for trades is written by somebody selling it, which is why the figures never quite match. The same case study is a 25% saving in one article and zero errors in another, and the call handling numbers everybody quotes have no sample size behind them.
So this is the other version. Job management software for tradesmen, AI that answers the phone for a plumber or drafts the quote for an electrician, smart glasses, digital certificates. What each one costs once the licences and the training are in rather than the price on the box, what the independent evidence shows, and the part of the job it leaves exactly as it was.
