Be the Expert, Not the Salesperson

Imagine a personal trainer named Nadia Osei who trains clients in their homes. In January, Mr. Whitfield calls her. He is 58, and he sold his company last year. He has entered a marathon in April, 14 weeks away, and he wants four sessions a week to get ready. He runs three miles twice a week, and his right knee was operated on last spring.

Nadia has two more clients that morning, and she would like Mr. Whitfield on her books. “Let’s do it,” she says. She books him for four sessions a week until the race, at $150 a session. In the ninth week, his knee swells after a long run, and his doctor tells him to stop running for two months. He misses the marathon and stops his sessions in March. When a friend at his club asks about Nadia, he says, “She’s pleasant. She’ll take you on for anything.” The friend hires someone else.

Suppose instead that Nadia asks a question first. “How far are you running now?” He tells her, and she asks about the knee. Then she asks why April. “I want to run one before I’m 60,” he says.

“Then I wouldn’t run this one,” Nadia says. “Fourteen weeks from three miles, on a knee that was operated on last spring, is how runners get hurt. Train with me for a half marathon in June, and run the full one in the fall. You’ll still do it before 60.” Mr. Whitfield books three sessions a week. He runs the half in June and the marathon in October. When his friend asks about Nadia, he says, “She talked me out of April, and she was right.”

Nadia knew the same things about running both times. What changed was whether she treated the call as a sale or as advice. In the first version, she said yes to what Mr. Whitfield asked for. In the second, she asked how he ran and what he wanted. Then she said what she would do, and she told him that April was not right for him.

Once a client has hired you, telling them not to spend earns their trust. In a sales conversation, the same no comes before the client has hired you. The job you might lose is the one you are discussing. Here is why a client trusts the professional who says it anyway, and how to say it.

A New York agent told a young buyer no, and he sent her 12 clients

Frances Katzen is a real estate agent in New York City, and she has sold homes there for more than two decades. In May 2026, she wrote a post for the Luxury Presence network about a lesson from her early years. In her second or third year, a young man came to her through his mother.

They went out looking. “The moment he pointed at a place and said ‘I want that,’ I told him no,” she writes. She gave him her reasons. “No light on the terrace, nonexistent view, not the best street, and he could do better for the budget.”

“So we waited seven months,” she writes. He bought “something right,” and he later sold it after it rose 70% in value. From then on, he referred her to “12 of the biggest financial titans on Wall Street,” and he still sends her clients. She puts the whole story down to one choice. “That deal happened because I was focused on advising, not selling.”

Katzen’s no came with four reasons the buyer could check for himself. She did not ask him to trust her taste. She told him what was wrong with the place, and that his budget could buy better.

A client can tell when someone only wants the sale

In the same post, Katzen says why the no worked. “We’re in sales. The instinct is to close, to win, to be number one,” she writes. “But that space is grabby and one-sided, and your clients can feel it. They can tell in two seconds if you’re full of it.”

Most of her clients, she writes, have spent their careers managing risk, and they have “zero patience for someone who’s just trying to move a unit.” Saying why not changes how they see her. “People immediately understand you’re there to walk them through the decision with their money in mind, not yours.”

She also names the other way to do the job. “There’s a version of this job where you say yes to everything,” she writes. A professional who will not speak up, she says, is “just taking orders.”

Katzen’s clients are buying homes worth millions, and the step to a trainer or a florist is the course’s own. Here is the step. A client choosing someone to look after their knee or their wedding also wants to know whose interest comes first. A yes to everything does not answer that question. A no with reasons does, because it is the one answer a person chasing the sale would not give.

A photographer who left every decision to her clients started asking, and raised her prices

Jenny Edwards is a portrait photographer in Amarillo, Texas. In 2018, she wrote in Fstoppers about a session that changed how she works. A mother whose family she had photographed several times asked for another shoot. Edwards texted her a time and a place, and she asked no questions.

At home, sorting the photos, she had a strange sense that she had seen them before. She looked up the family’s last session. It was the same location and the same poses, and the father was “wearing almost exactly the same outfit as last time.”

Edwards saw what had gone wrong. “By having no discussion with my clients about their expectations or desires, I was in fact leaving every decision to them,” she writes. “And guess what? They aren’t photographers.”

Now she holds in-depth consultations before a shoot. She advises asking clients what the photos are for, such as holiday cards or “a special portrait to hang over the fireplace.” Then she shows them ideas. “You not only need to know their desires, you also need to be able to tell them their possibilities, because odds are, they won’t even know what their options are,” she writes. Since she started, she has raised her prices to an average of more than $1,000.

Edwards did not push anyone. Her mistake was the one Katzen calls taking orders. Her fix puts the asking first and the advice second. The client knows how they live, and the expert knows what is possible. Advice needs both.

Why saying no before you ask goes wrong

Imagine a travel adviser named Corinne Vale who plans trips for families. Mrs. Haddad calls about a week in August at a large resort in Mexico. Corinne knows the resort well. In August it is crowded and loud, and the food is ordinary. She is between two calls. “That’s not right for you,” she says. “It’s packed in August. I’d put you in a small hotel in Tulum instead.”

Mrs. Haddad goes quiet. She chose the resort because her three grandchildren want the water slides, and both her children’s families are coming. To her, it sounds as if Corinne has taken her for the kind of client who wants a quiet hotel. Mrs. Haddad thanks her and books the resort herself that evening.

Corinne was right about the crowds. Her mistake was the order. She said no before she knew what the week was for. So her no was about her own taste, not about Mrs. Haddad’s family. The version that works asks first. “What’s drawing you to that resort?” Once Corinne hears about the grandchildren, she can see that the resort is right for this trip. Then her advice is about how to do it well. “It’s full in August, so I’d book the family suites on the quiet side now.”

Saying no to a client is not talking yourself out of the job

Telling a client that what they want is wrong for them can feel like giving the job away. The next professional will say yes. Katzen writes that you speak up “even when it might cost you the deal in the short term.”

Her young buyer did not leave. He waited seven months with her, and from then on he sent her clients. A no that comes with what you would do instead also leaves the client something to hire you for. Nadia gives up April, and she keeps Mr. Whitfield for the half marathon in June and the full one in the fall.

How to act as the expert in a sales conversation

Before you say what you would do, ask what the client wants the work to do and how it fits their week. Ask one question, and build the next one from the answer. For example, a dog walker can ask, “How long is Biscuit on her own during the day?”
When you have heard enough to advise, say what you would do and give your reason. Include the options the client may not know to ask for. For example, a private chef can say, “Some families have me cook on Sunday and leave four dinners for the week. With your travel, that might suit you better than three nights.”
When what the client wants will not get them what they told you they want, tell them in the same conversation. Give your reasons, the way Katzen gave four, and say what you would do instead. For example, an event planner can say, “I wouldn’t hold it in the garden in late October. It’s dark by six and cold by seven. The barn would hold all 80, with heaters.”
If the client still wants what you advised against, decide whether you can do it well. If you cannot, tell them you are not the right person for it. That is the course’s suggestion, because a job you advised against and then did badly costs you the client. For example, a personal stylist can say, “If you’re set on the whole collection, I’m not the right person to help you choose it.”
