Size the water and balance it in seconds. Get your pool volume in gallons by shape, then the exact chlorine, acid, baking soda, and stabilizer to add — or price a weekly service route.
That's the hard part done. SideWRK runs the rest from your phone: text the estimate, your customer taps approve, and the money hits — card, Apple Pay, Venmo, Cash App, or Zelle, no merchant account, no three-percent bite. It keeps a line on who still owes you, logs every material and cost so your real profit and your tax write-offs tally themselves, and stands up a free website with reviews that feeds you the next job. A free estimate today, or your whole operation in one app. Built for pool service and every trade.
Pool money is recurring money — the weekly route is the business, and every visit is volume times chemistry. Nail the gallons once and every dose falls out of it. Balance in the right order (alkalinity, then pH, then hardness, then stabilizer, then chlorine), never stack two strong doses, and keep acid and chlorine apart. Price the route by pool size, bill it monthly, and let the one-time green-pool jobs be the audition for a weekly account.
