Every plumbing business sends quotes that go cold. Most owners assume those jobs went elsewhere on price. The data says otherwise - and the maths behind what those lost follow-ups could represent is worth working through.
Most plumbing business owners assume that when a quote goes cold, the client chose someone cheaper. That may be true a fraction of the time. The more common reason, according to job-management data from platforms like ServiceM8 and Tradify, is simpler: the first business to follow up wins, regardless of price.
This article walks through how to calculate what slow or absent follow-up may be costing your business - and what a structured follow-up system typically does to that number.
Why plumbers lose quotes they should be winning
The pattern is consistent across the trades businesses I audit: a plumber sends 15-25 quotes in a busy week. A handful close immediately - the client calls back, the job goes ahead. The rest sit in a sent folder and either come back weeks later or vanish entirely.
When those owners ask why, the instinct is to blame price. Occasionally that’s right. More often, the lead moved on to the first business that followed up. Not the cheapest. The first.
Research on service-business enquiries consistently shows the same dynamic: response speed matters more than price across a wide range of service categories. In trades specifically, where customers are often dealing with a problem (a leak, a blocked drain, a hot water system that died this morning), the first quote with a follow-up attached tends to close the job.
The plumber who sent the quote and waited is competing against the plumber who sent the quote and then texted 48 hours later to ask if the client had any questions.
Working through the maths
Let’s use a straightforward example. Take a plumbing business sending 20 quotes per week with an average job value of $800.
At a 35 percent close rate - a reasonable baseline for a business without a formal follow-up process - that’s 7 closed jobs per week. Revenue: $5,600 per week.
Now apply a structured 7-day follow-up sequence: an SMS at 48 hours, another at 5 days, a final touch at 10 days. Based on internal benchmarks from businesses that have implemented this kind of sequence, a lift of 10-15 percentage points on close rate is achievable, though results vary depending on the business, the type of work, and how the messages are written.
At a more conservative 10-point lift - moving from 35 to 45 percent - the same 20 quotes per week produce 9 closed jobs instead of 7. That’s 2 extra jobs per week at $800 each: $1,600 per week, or roughly $83,000 over 52 weeks.
At 15 quotes per week and a $600 average job, the same lift could represent $46,800 annually. At 25 quotes and $1,200 average, it approaches six figures.
These are worked examples, not guarantees. Your actual lift will depend on how good your follow-up messages are, how responsive your market is, and what you’re quoting on. But even at a third of the estimated impact, the follow-up sequence is one of the highest-return changes a plumbing business can make.
The three points in the sequence that matter
A quote follow-up sequence doesn’t need to be complex to work. Most of the plumbing businesses that see the biggest lift use three touchpoints:
48 hours after the quote goes out. A short SMS checking whether the client received the quote and has any questions. This is not a hard sell - it’s a confirmation that you’re responsive and interested in the job. Many clients haven’t had a chance to look at the quote properly by this point and appreciate the nudge.
5 days out. A brief message noting that you have capacity coming up and can schedule quickly if they want to move ahead. This targets the clients who are interested but haven’t got around to confirming. The “I have a window” frame gives them a low-pressure reason to respond.
10 days out. A final touch. If the quote is still open and the client hasn’t responded, a short message closing the loop: you’re still available if they need you, happy to answer any questions, and the quote is valid until a certain date if you want to specify one.
After 10 days with no response, most quotes are genuinely dead. Chasing beyond this point produces diminishing returns and occasionally irritates people who have already decided. Three touchpoints, 10 days, then move on.
Why most plumbers don’t do this manually
The obvious question is why this doesn’t already happen. Most plumbers know they should follow up. Most don’t do it consistently.
The practical answer is time. A busy sole trader or small crew has almost no admin time. Sending one follow-up on one quote when you remember to is manageable. Maintaining a consistent 3-touchpoint sequence across 15-25 live quotes at any given time, while you’re also managing active jobs, invoicing, and phone calls, is not something a human can do reliably without a dedicated admin.
That’s the gap a structured SMS system fills. Once it’s set up, it runs without requiring anything from you. A quote goes out and the sequence fires automatically. You get to focus on the work.
What the sequence looks like in practice
The PlumberText AI Engine is built specifically for this. It includes a vault of 50 SMS templates written for Australian plumbing businesses - covering quote follow-up, job completion, payment reminders, and seasonal maintenance prompts - along with an AI dispatcher that helps you write and adapt messages for specific jobs.
The templates follow the 3-touchpoint structure above. They’re written in plain English, without the corporate tone that looks out of place in a text message, and they’re short enough to read in under 10 seconds.
At $27, it’s the lowest-cost entry point into a structured follow-up system you’ll find. You can adapt and use the templates without any other software - copy, paste, send. Or connect them to Make or Zapier if you want the sequence to fire automatically from your existing job management system.
The follow-up problem is real. The maths behind fixing it are better than most plumbers expect. The barrier to starting is lower than most think.
