What is the GUEST Technique in Customer Service?

Learning new customer service techniques can help you better sell jobs over the phone or in person with your customer. One of the helpful customer service techniques you might want to try is GUEST. We’ll explore what this technique stands for and how to use it as a contractor or small business owner below.

How the Right Customer Service Technique Can Streamline Your Business

Customer service isn’t just about answering phones and resolving complaints — it’s a key driver of efficiency, reputation, and growth. The right customer service techniques can significantly streamline your operations, reduce costs, and improve overall customer satisfaction.

1. Faster Issue Resolution Saves Time and Resources

When service reps use structured communication techniques — like active listening, clear documentation, and follow-up protocols — customer concerns are addressed more efficiently. Fewer repeat calls, less confusion, and reduced strain on other departments mean smoother operations and more time for higher-value work.

2. Consistent Service Reduces Errors and Miscommunication

Training your team in standardized service methods (such as using scripts, CRM tools, and email templates) ensures consistency. This consistency reduces the risk of miscommunication, improves handoffs between departments, and creates a more predictable, manageable workflow.

3. Proactive Communication Prevents Bottlenecks

Using customer service techniques like proactive status updates, estimated timelines, and clear next steps helps eliminate unnecessary follow-up calls and emails. When customers know what to expect, they don’t need to check in — which frees up your team to focus on actual tasks rather than constant interruptions.

4. Empowered Staff Make Smarter Decisions

When customer service teams are trained in problem-solving, conflict resolution, and product knowledge, they’re better equipped to handle issues on the spot. This avoids delays from unnecessary escalations and keeps the customer experience fast and seamless.

5. Positive Experiences Build Loyalty and Reduce Churn

Good service doesn’t just solve problems — it prevents them. A smooth customer experience reduces frustration, encourages repeat business, and leads to fewer complaints over time. That means fewer reactive tasks and more predictable, stable operations.

G for Greet Your Customer

Focus on making a strong impression on every customer by greeting them with genuine enthusiasm. It can be hard to make repeat sales calls and avoid jumping right into a pitch. But this is the first time your customer is hearing from you and your first chance to make a good impression. Starting with a heartfelt greeting is best. Some greetings to try include:

• “Good morning, thank you for calling Jane’s Plumbing.”
• “Hello, my name is ___, and I’d like to help you today.”

U for Understand the Customer

After you greet the customer, you can attempt to speak, or you can try to listen. Listening is best because it helps you understand your customer’s true needs before you attempt to sell to them. If your customer didn’t open up after your greeting, it’s wise to ask a few open-ended questions to try to prompt discussion. You should ask relevant questions for your business, of course, and try to stay away from generalities like “what are you looking for?” Instead, try, “what do you need from a roofing company today?” or “which part of your plumbing system are you concerned about?” The more specific, the more genuine your concern sounds.

E for Explain Your Product or Service

You know your product or services so well that it might seem patronizing to jump into explaining the benefits. However, most customers will not be as familiar as you are with the benefits of your work and explaining it to them directly is helpful. That’s even when a customer is already sold on the benefits of the product or service in general. Consider:

• “When you get an air purifier from us you also get a great warranty.”
• “Our company cares about our customers for the long term. Is you have a problem after your water heater installation we will be happy to return, free of charge.”

We don’t suggest that you do this during an emergency call. In this case, delaying scheduling for a bit of selling can be frustrating and make the customer feel like you don’t care about the serious situation they are facing. The same goes for our next tip.

S for Suggest More

Upselling is when you suggest an additional product or service that you know the customer might benefit from. It’s a great way to make your average customer more valuable. For contractors, the common upsell is a maintenance package. But, depending on your line of business, many other suggestions might work. As long as you suggest something relevant, your customer won’t be frustrated.

For example:

• “If you’re getting new sod for your lawn, you might also want our garden bed clean-up service.”
• “You can really make the most of your time at our event venue by booking out one of our on-site hotel rooms.”

T for Thank

At the end of your call, always thank your customer, even if they didn’t purchase anything. They reached out, and that’s reason enough to say thanks.
