How tradesmen can handle customers better
Good communication in a trade is not charm. It is being specific, early, and in writing, especially when the news is bad.

The four conversations that go wrong
Almost every serious complaint in a small trades business comes from one of four moments, and all four are predictable enough to prepare for:
- We are going to be late, or not coming today. The one that generates the most anger, and the easiest to handle well.
- It is going to cost more than I said. Handled badly on site, it becomes a dispute at invoice time.
- We found something else. Genuine extra work that the customer did not ask for and may not want.
- It has gone wrong. A part failed, damage occurred, or the fix did not hold.
None of these is avoidable in a trade. What is avoidable is finding out about them from the customer rather than telling them first.
What to say, roughly
Running late: the new time, not an apology first. “I am going to be with you about half two rather than eleven, is that still workable?” gives them a decision to make rather than a grievance to hold.
Costing more: stop and say it before doing the work, with the number. “That is going to be another ninety pounds because the valve is seized, do you want me to do it?” A price agreed on site is not a dispute. A price discovered on an invoice is.
Found something else: separate what is urgent from what is worth knowing. “The isolator is fine for now but it is at the end of its life, I will note it and you can decide later” is useful. A list of everything wrong with the property reads like a sales pitch.
Gone wrong: say what happened, what you are doing about it, and by when. Do not lead with liability, and do not disappear. The businesses that recover from mistakes are the ones that answered the phone.
Write it down, even when you rang
A phone call is the right way to deliver bad news. It is a poor way to keep a record, and in a disagreement six weeks later the written note is what settles it.
The habit that costs nothing: after the call, send two lines confirming what you agreed. “As discussed, extra ninety pounds for the valve, and we will be back Thursday morning.” That is not bureaucracy, it is the thing that protects you both.
It also protects the customer from your memory, which matters. A business that writes things down is trusted differently.
Where Dispatch fits
Two things keep the conversation with the job rather than in a personal phone.
Job chat is a two-way thread about a specific job, with photographs, opened by sending the customer a link over WhatsApp or text. The customer needs no account. Staff post as the business, not as a named person, so nobody ends up with a customer texting them at nine on a Sunday. The thread closes itself when the job is completed or cancelled and stays readable.
Because it is attached to the job, the messages sit with the quote, the visits, the photographs and the invoice. When an engineer leaves, the conversation stays with the business.
And appointment emails cover the first conversation automatically: the customer is emailed when a visit is booked, moved to a different day or cancelled, which is the lateness problem handled before it becomes a phone call.
The customer side of the chat polls for new messages every ten seconds or so. It is quick but not instant, and it is not the right channel for something genuinely urgent.
The one that pays for itself
The completion report is the most underrated piece of customer communication in this trade. A short plain-English account of what you did, with photographs, sent or available when the invoice arrives.
It prevents the “what am I actually paying for” conversation entirely, it is the evidence if the work is queried a year later, and it is the single most common reason customers recommend a trades business to a neighbour.
If you want the routine version of all this rather than the awkward version, keeping customers updated on job progress covers the four moments that need covering in an ordinary job.
Questions
Customer communication: FAQ
How should I tell a customer the job will cost more?
Before doing the work, on site, with the number and a clear yes or no question. A price agreed on site is a decision. A price discovered on an invoice is a dispute.
Should I ring or message?
Ring for bad news, then send two lines confirming what you agreed. The call carries the tone and the message carries the record.
How do I stop customers texting engineers directly?
Keep the thread on the job. In Dispatch staff post as the business rather than as a named person, and the thread closes when the job is completed, so it never becomes a private channel.
Is job chat instant?
Close, but not instant: the customer side checks for new messages every ten seconds or so. For something genuinely urgent, ring them.
What reduces complaints the most?
Telling people before they have to ask, and a clear completion write-up with photographs. Most complaints are about silence rather than about the work.
