Difficult customers are not a sign that you are a bad tradesperson. They are a sign that you are in business. Every Irish tradesperson deals with them.
The question is not how to avoid them. The question is how to handle them when they appear. Handle them well, and you keep the customer and protect your reputation. Handle them poorly, and you end up with a bad Google review and a bad reference.
Here is how to navigate the three types of difficult customer.
The Three Types of Difficult Customer
The unreasonable complainer. Everything is wrong. The finish is not perfect. The timeline was not fast enough. The invoice is too high. Nothing you do satisfies them. They find something to complain about no matter what.
The late or non-payer. They want the work done urgently. You drop everything, do the job, and then they avoid paying you for three months. Or they offer half the agreed price.
The scope creeper. “While you’re here, can you also…” This customer starts with a small job and keeps asking for extras. They expect them for free or at a tiny discount.
Most difficult customers fall into one of these categories.
Preventing Problems Before They Start
The best defense is prevention.
Get everything in writing. A verbal agreement is not an agreement. Your quote should specify exactly what work will be done, what it includes, and what it does not. If it is not in the quote, it is not part of the job.
Agree scope before you start. Have a conversation about exactly what you will and will not do. Confirm it in writing. This prevents later disagreements about what was promised.
Send written change orders for extras. If the customer asks for additional work mid-job, send them a written quote for that work. They sign off on it. This prevents “I thought that was included” disputes later.
These three things prevent 80% of customer problems.
When a Complaint Comes In
Stay calm. Listen first. Do not argue or get defensive immediately.
A customer is upset. Your first job is to understand what went wrong from their perspective. Ask questions. Listen to the answer. Do not interrupt or explain why they are wrong.
Once you understand the complaint, decide: Is this a legitimate complaint or bad faith?
Legitimate Complaints
If the customer is right, fix it. Fix it fast. Do not let it fester.
If you did a sloppy job or missed something, go back and put it right. An hour of your time now is worth far more than a bad Google review that lasts forever.
A fixed problem rarely becomes a bad review. A problem that is ignored or poorly handled becomes a permanent reputation issue.
If you fix it quickly and well, the customer often becomes a better reference than someone who never had an issue. They remember that you stood behind your work.
Bad Faith Complaints
Some customers complain in bad faith. They want free work or a discount they did not earn. They are looking for leverage.
How do you tell the difference? Look at the complaint in context. Did this customer complain about everything? Are they asking for a discount on already-agreed work? Do they keep moving the goalposts?
If it smells like bad faith, stop arguing face-to-face. Move to writing.
Document everything. Get all your communications in writing. Refer to the quote. Explain calmly why you believe the work meets the agreed scope.
Stay professional in writing. Do not be emotional or defensive. Stick to facts.
“You asked for the ceiling to be painted white. I painted it white as agreed. The invoice reflects the agreed price.”
Most bad faith customers back off when you move to writing. They know you are documenting everything.
Scope Creep: The “While You’re Here” Problem
You are mid-way through a kitchen refit. The customer says, “While you’re here, can you also put up some shelves? Oh, and paint that wall? And move that socket?”
This is scope creep. It happens constantly.
Handle it in the moment. Do not just do the extra work because you are there.
“That was not part of the original agreement. I can add that to your quote, but it will be extra work and extra cost. Want me to give you a price for it?”
Some customers accept the extra cost. Some say no. Either way, you have prevented giving away free work.
Write down what you agreed to add. Send them a change order quote later. They approve it or they do not.
Do not do the extra work until they approve the cost.
Non-Payment
This is the worst case and unfortunately common.
The best approach: Prevent it. You do not always get paid upfront, but you can get a deposit. 25-50% deposit on larger jobs is standard. This protects you if they do not pay the balance.
For small jobs under 500 euros, payment on completion is reasonable. For larger jobs, a deposit protects you.
If they do not pay after the job: Send an invoice immediately. Give them 10 days to pay. If they do not, send a reminder. If they still do not pay, use the Late Payment Act.
The Late Payment Act: Ireland has the Late Payments of Commercial Debts (Interest) Act 1999. This allows you to charge interest on overdue invoices and recover collection costs. You can apply 8% plus the Central Bank rate to overdue invoices.
This is a legal tool. Use it. Send a formal letter stating the debt, the amount, and that you are applying interest under the Late Payment Act. Many customers pay once they realize you are serious.
Small claims court: For debts under 2,000 euros in District Court, you can take the customer to small claims court. This costs roughly 100-200 euros and takes a few weeks. Most customers settle rather than face court.
Document everything for this. Invoices, quotes, change orders, all in writing.
When to cut your losses: If the debt is small and they are clearly avoiding you, sometimes it is better to write it off than to spend energy chasing it. If it is large, pursue it.
Responding to Bad Google Reviews
If a customer leaves a bad review online, respond. Calmly. Professionally. Without being defensive.
“We are sorry you had this experience. We pride ourselves on quality work. We would like to resolve this. Please contact us directly.”
This shows potential customers that you care about resolution. It also shows you are professional even under pressure.
Do not argue with the reviewer. Do not say they are lying. Do not get emotional.
If the review is clearly false or you have evidence they are wrong, you can briefly explain. But keep it professional and factual.
Most people reading reviews understand that some complaints are exaggerated. A professional response to a complaint makes you look better, not worse.
When to Walk Away
Some customers are not worth having. If a customer is demanding, rude, unreasonable, and has no intention of paying fairly, sometimes the right call is to decline the work.
You do not have to work for everyone. A customer who causes stress and eats your time is not profitable even if you invoice them.
If you have completed work for a customer and it was a nightmare, you do not have to do future work for them. It is okay to decline politely.
Your peace and reputation are worth more than one difficult customer.
