Pool service companies often grow by buying routes, and a route purchase can add trucks, techs and chemical habits to your account in a single week. The seller's techs may drive their own pickups, store acid next to shock in an open bed or keep a bulk supply in a garage at home. Little of that shows up in a purchase agreement, yet it can become your exposure the first morning those trucks run your accounts.
Before closing, walk the incoming trucks the way an underwriter would. Note who owns each one, what rides in it and where it parks. Company trucks that come with the deal go on your schedule before they roll; techs who keep driving their own pickups need their records checked and your hired and non-owned coverage behind them. Then apply your storage rule from day one so the new routes don't run on the old owner's habits while you sort out the paperwork.
