Software for a Plumbing Company With Employees: The Answer the Forums Never Give

There is a question that appears in the trade forums every few weeks, worded almost exactly the same way each time: what is the best software for a plumbing company with employees? The thread always goes the same way. Three people name the app they happen to use. Someone says "spreadsheets are fine". Someone else says "get a VA". Nobody actually answers the question, because the honest answer needs more than a product name. It needs an explanation of what actually changed the day you took on your first employee. So here is the answer those threads never give.

What changes at employee one

The day you hire, three problems appear that did not exist the day before. None of them are plumbing problems. All of them are information problems.

Your diary becomes a rota. Solo, your calendar is the business. You know what "Tuesday" means because you are Tuesday. With an employee, every booked job now carries a second question: who is doing it? Two people, two vans, holidays, a sick day, a job that overruns. The diary stops being a list of jobs and becomes a matching problem between jobs and people, and a spreadsheet starts dropping stitches within weeks.

Dispatch becomes a real job. Somebody has to decide whose van goes where, tell them, and handle the ripple when an emergency lands in the middle of a planned day. Solo, that decision took zero seconds because there was no decision. Now it takes real time every single day, and every mistake costs a drive across town or an angry customer.

The phone becomes the bottleneck. Here is the trap almost every new employer walks into: you hired so more work could get done, but you are still the only person who can answer the phone, quote, and book. So you spend your day on the tools ignoring the phone, or off the tools being an expensive receptionist. The wage bill went up and the booking capacity did not.

And underneath all three sits the money fact that changes your priorities completely: an employed plumber costs you their wage whether the diary is full or not. Solo, a quiet Thursday was lost income. With employees, a quiet Thursday is money actively leaving the building. Empty diary hours are now the most expensive thing you own, which means the software question is really a diary-filling question.

The three categories of software, honestly

Almost everything the forum threads recommend falls into one of three buckets. They solve different problems, and the names on the boxes do not make the differences obvious.

Shared diary apps. Google Calendar, a whiteboard photo in the group chat, a shared spreadsheet. Free or nearly free, and genuinely fine at two people with a calm workload. They break at dispatch: no job details attached to slots, no customer records, nothing connecting the booking to a quote to an invoice, and no way for a customer to book themselves in. You will feel the ceiling within months, but it is an honest starting point.

Job management software. Tradify, Powered Now and their peers. These run the job after you have won it: quotes, job cards, assigning work to team members, invoices, records. Usually priced per user. For a plumbing company whose enquiries arrive fine but whose paperwork is chaos, this category is the right answer, and we say that as a company that sells something else. We compared this category against accounting-led setups in Xero vs job management software if that is your fork in the road.

Booking-first software. This category starts one step earlier: it wins and schedules the job at the enquiry. A booking page shows real availability across your whole team, the customer picks a slot and pays a deposit, and the system routes the job to the right person. It exists to solve the phone-bottleneck problem and the empty-diary-hours problem specifically. This is the category OptiTech Automation is in, and we will get to it properly below, after the criteria.

Run the diagnosis: one week of counting

Before you compare a single product, spend one normal week counting five numbers. Keep a note on your phone, tally marks are fine.

• Enquiries that arrived outside the hours anyone could answer (evenings, weekends, both of you on jobs).
• Missed calls that never got a call back, because by the time you surfaced, ringing back felt pointless.
• Hours you personally spent booking, quoting and shuffling the diary instead of doing billable work.
• Paid employee hours that sat empty or got filled with make-work because nothing was booked in.
• Invoices sent later than they should have been, and the cash-flow gap that opened because of it.

Put a pound figure next to each one. Your day rate against the admin hours. An average job value against the missed enquiries. The hourly wage against the empty hours. The result is your leak table, and it makes the software decision almost boring: you buy whatever attacks the biggest number. Two plumbing companies with identical vans can come out with opposite answers, and both be right.

How to choose: criteria, not crowns

Ignore anyone who tells you the best tool without asking about your business first, including us. Ask yourself these instead.

• Where does money leak first? Count a normal week. If jobs are lost before they are booked (missed calls, slow quotes, evening enquiries dying), you need booking-first. If jobs are won fine but cash arrives late and paperwork eats your evenings, you need job management. This one question does most of the choosing.
• Who answers the phone at 2pm on a Tuesday? If the answer is "nobody, we are all on the tools", you need something that books jobs without a human, or you need to hire a human. Price both options. Software that books while you work is competing with a receptionist's salary, not with other software.
• Does it know about your rota? With employees, a booking system that does not understand who is available is a diary with a lie in it. Holidays, working patterns and skills need to shape what customers can book.
• What does it cost at your size in two years? Per-user pricing is kind at three users and unkind at ten. Banded pricing is the reverse: heavy at three, sensible at eight. Do the arithmetic for the company you are building, not the one you have.
• Can you leave with your data? Customer list, job history, the lot. If export is vague, the price is higher than the invoice says.

Where OptiTech Automation fits, honestly

OptiTech Automation is booking-first software built for exactly the moment this post describes: a trade business that has stopped being one person. The booking page shows real slots based on your team's actual rota, takes a deposit at the moment of booking straight into your own Stripe account with a 0% platform cut, and dispatch routes each job to the right pair of hands. The point is that bookings happen, correctly, while every one of you is on the tools. The team-side detail lives on the software for trade teams page.

Pricing, plainly, because vendors hiding numbers annoy us as much as it annoys you: Start-up is £199 a month plus a £129 setup fee and covers up to 5 people on the tools. Standard is £599 a month plus a £249 setup fee and covers up to 15 people on the tools. Growth is £1,749 a month plus £999 setup and covers up to 30. Bands, not per-user meters, and moving past a band means moving up a plan.

And the honest line: if you are still solo, or your real pain is quoting and invoicing rather than booking and dispatch, we are the wrong choice. Buy job management, or stay on the shared calendar a while longer, and keep the money.

The answer, in one paragraph

The best software for a plumbing company with employees is the one that attacks your dearest leak. If work is won fine but admin is drowning you: job management, and Tradify or Powered Now are respectable places to start. If the phone is the bottleneck and paid diary hours are sitting empty: booking-first, and that is the category we build in. Decide with a week of counting, not a forum thread. And if you are still deciding whether that first hire should be an employee at all, read how to hire workers for your trades business legally before you sign anything, because the employment decision is bigger than the software one.
