Pool service software for routes, water chemistry and GST invoicing

A pool maintenance business runs on a rhythm: pools go on a cycle, you run the route, you test and balance the water, you sell the chemicals and the occasional equipment upgrade, you invoice, and you keep customers on plan so the work is predictable rather than feast-or-famine. OneBookPlus supports every stage of that rhythm, from the recurring schedule that builds your run sheet through to the recall reminder that turns a one-off summer clean into a year-round account.

Recurring routes and scheduling

Most pool revenue is recurring, weekly and fortnightly maintenance across a geographic run. Put each pool on its cycle and OneBookPlus builds the schedule for you, groups your day's pools into a run sheet, and fires reminders so nothing is missed. Slot one-off jobs, green-pool recoveries, equipment repairs, pre-sale inspections, between your regulars, and assign pools to specific techs if you run a team. The week view shows exactly who is where, so you can quote a new account knowing where it fits, and a missed visit is obvious before the customer notices.

Water testing and chemical history

At each pool you record the water test, free and total chlorine, pH, total alkalinity, calcium hardness, salt, stabiliser (cyanuric acid), and log the chemicals and quantities you dosed. Over weeks and months this builds a complete water-chemistry timeline against each individual pool, so you can see a trend before it becomes a green pool, justify a chemical charge to a customer who queries the bill, and hand a clear history to a new tech who picks up the route. Liquid chlorine and acid are dangerous goods handled under state work-health-and-safety and dangerous-goods rules; keeping accurate dosing records and your supplier Safety Data Sheets to hand supports safe, accountable servicing.

Pool and equipment records

Every pool gets its own record, volume, surface type, the pump, filter, chlorinator and heater models, access notes, the gate code and any quirks. When you're standing at the equipment pad you can see the last cartridge change, the salt-cell install date and its warranty status, and the history of past repairs. That turns a reactive callout into a planned upgrade conversation: a chlorinator cell that's nearly four years old and dropping output is a quote you can raise on the spot rather than a surprise breakdown next month.

Quoting, invoicing and GST

Routine visits invoice themselves at the standing rate, per visit or batched into a monthly statement, with your ABN and 10% GST calculated automatically. Chemical sales and one-off repairs drop on as separate line items, so the bill is clear and your margin is visible. For larger work, pump replacements, salt-chlorinator upgrades, leak repairs, heater installs, build an itemised quote at the poolside that the customer accepts from their phone, and convert it to an invoice when the job is done. Pool servicing and pool products are standard GST-taxable supplies in Australia, so there's no health-style exemption to worry about; at BAS time your GST summary exports in one click.

Chemicals as dangerous goods, and what the dosing log is for

Liquid chlorine, hydrochloric acid and granular oxidisers are dangerous goods. How you store them at the depot, how much you carry in the van and what your team is told about handling them sits under state work-health-and-safety and dangerous-goods rules, with supplier Safety Data Sheets as the reference document. Those sources are linked at the foot of this page. The software part is narrow and worth being clear about: OneBookPlus does not assess your storage or write your risk controls. What it does is make the paper trail retrievable. Each visit carries the product, the quantity dosed and the readings that justified it, so a dose is attached to a reason rather than to memory. Safety Data Sheets and your own handling procedure can be attached as documents the team opens from the same app they run the route in, instead of a folder in the depot nobody visits. When a customer with a rash, an insurer, or a new technician asks what went into that pool and when, the answer is a search on the address.

Pricing a route that still works in July

Pool work is the most seasonal trade on this list. Summer brings green-pool recoveries and one-off cleans at full rate, and then the phone goes quiet, the fortnightly accounts drop to monthly, and the fixed costs of the van do not drop with them. Two things make the difference between a business that rides that out and one that discounts its way through winter. The first is knowing the number you need per serviced pool before you quote the next account, which is what the hourly rate calculator for tradies and the break-even calculator are for. The second is seeing the trough before it arrives, which is a cash-flow question rather than a pricing one, and the cash flow forecast calculator gives you a view of it. In the product, the levers are recurring plans that keep billing through the cooler months, recall prompts that put a filter clean or an equipment check in front of a seasonal customer in April rather than November, and per-pool chemical costing so a heatwave that doubles your chlorine bill shows up as a margin problem instead of a mystery. The same recurring-route logic sits behind OneBookPlus for landscaping and garden maintenance rounds, if you run both kinds of work off the one van.

Reminders, recalls and growth

Growing a pool business comes down to keeping the recurring accounts you have and converting one-off and seasonal customers onto a regular plan. OneBookPlus does both. Automated service reminders prompt customers when a filter clean, equipment service or seasonal check-up is due, and recall prompts reach out to summer-only and green-pool customers before they drift to a competitor. After a job, automatically request a Google review from happy customers to win the next person searching "pool cleaner near me," and your branded booking page doubles as a lightweight website that takes new enquiries 24/7. The dashboard ties it together, routes, chemistry, reminders, revenue and BAS-ready financials in one place, so you always know exactly where the business stands.
