Build Route and Chemistry Software for Pool Service Companies

1. 1

   Ride two full route days before you design anything

   Not a phone interview. Ride the truck. Time every stop, note every reading, watch where the tech writes things down and where the paper gets lost, and count how many times they drive back past a pool they already passed. You are looking for the minutes and the jugs, because those are the two currencies this product is paid in.

2. 2

   Build the stop screen and make it work with no signal

   The tech is standing behind a house, phone in one hand, test kit in the other, often with no usable connection. The whole stop must be enterable in under ninety seconds, work fully offline, and sync when the truck moves. If this one screen is slow or drops data, nothing else you build matters because the techs will quietly go back to paper.

3. 3

   Write the chemistry engine and have a professional check it

   Readings in, dose out, in the units and product forms the operator actually carries. Handle saturation index balance, stabiliser effects on chlorine demand, and the difference between liquid and granular dosing. Then get a certified pool operator to review your outputs against their own judgement on twenty real pools. A wrong dose damages a customer's pool and your reputation in a small industry that talks.

4. 4

   Tie every dose to truck stock

   When a tech logs an addition, deduct it from that truck's inventory. That single link turns chemistry into cost accounting: cost per stop, cost per pool per month, and a restock list for the warehouse in the morning. This is the feature that gets the owner to open the software rather than only the techs.

5. 5

   Add route sequencing built for density, not for maps

   Optimising a fixed list of stops is a solved problem. The valuable version answers the operator's real question: which day should this new account go on so the route stays tight, and which accounts are so far out they cost more to serve than they earn. Show drive time as a share of the day and let the owner see density as a number.

6. 6

   Run three paid pilots with operators of different sizes

   One two-truck owner who is still on the route, one six-truck operator with an office person, one at the top of your range. Charge them from day one, even a token amount, because free pilots produce polite feedback. Measure minutes saved per stop and chemical cost per pool before and after.

7. 7

   Sell where the operators already gather

   This industry has trade shows, certification courses, regional distributor counters and very active owner groups. One operator with a real number about route time or chemical spend is worth more than any advertising, and route brokers who buy and sell pool routes make unusually good referral partners because they see the books.

Do not take our word for the money. Put your own numbers in and see what this idea has to earn before it works. Free, instant, no account needed.

Best for: Developers who can get access to a real pool route and are willing to spend days in the heat before writing a line of code

Not for: This is not for a founder who wants to ship in a month from a laptop. It needs real domain learning about water chemistry, offline mobile engineering that is genuinely harder than a web app, and physical access to working pool routes. Without a route to ride, you will build a scheduling tool with a chemistry label on it.
