Quotes go cold for more than one reason, and price is only one of them. How to work out what slow follow-up may be costing your plumbing business.
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. Another common reason is simpler: the first business to follow up often wins, whatever the 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 may do to that number.
Why plumbers lose quotes they should be winning
A common pattern: a plumber sends 15-25 quotes in a busy week. A handful close immediately, with the client calling back and the job going 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. Sometimes the customer simply went with whoever followed up.
Speed of reply can matter as much as price, especially in trades, where the customer is often dealing with a problem that needs fixing now (a leak, a blocked drain, a hot water system that died this morning).
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: a text at 48 hours, another at 5 days, a final touch at 10 days. As an illustration, assume a lift of 10 percentage points on close rate. Your result may be higher, lower or no lift at all, depending on the business, the type of work, and how the messages are written.
At a 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 that lift, the follow-up sequence is a low-cost change worth testing.
The three points in the sequence that matter
A quote follow-up sequence doesn’t need to be complex to work. A simple sequence uses 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 confirms 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.
By day 10 with no reply, more chasing risks irritating someone who has already decided. Three touchpoints, 10 days, then move on.
Why the follow-up slips
The obvious question is why this doesn’t already happen. Knowing you should follow up and actually doing it every week are two different problems.
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. Keeping a 3-touchpoint sequence going across 15-25 live quotes, while you’re also managing active jobs, invoicing and phone calls, is hard to keep up.
That’s the gap ready-written texts fill. Often the hard part of a follow-up is working out what to say. With the words already written, you fill in the name and send it between jobs.
What the sequence looks like in practice
The PlumberText AI Engine is built for this. It is a pack of 50 SMS templates written for Australian plumbing businesses, covering leads, quote follow-up, bookings, payment reminders, reviews and repeat customers, plus an AI Dispatcher prompt that drafts messages for the jobs the templates do not cover.
The pack’s 7-day plan uses the same idea: a check-in on day 2, another on day 5 and a close-the-loop text on day 7. The texts are 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.
It costs $27, once. There is no software and no setup. Copy, personalise, send.
The follow-up problem is real, the arithmetic is worth running on your own numbers, and the barrier to starting is low.
