B2B customer research only produces reliable answers when a neutral person runs it and the conversation leaves room for follow up questions. A survey measures what you already suspect. A personal interview reveals what customers would never tell your sales team.
Surveys measure satisfaction. Not the reasons.
Surveys are convenient. You can send them, analyse them and turn them into charts. The problem: they only answer the questions you knew before. Someone who ticks a seven on a scale of one to ten does not tell you why. Let alone what they currently like better about a competitor.
B2B adds another problem: few customers, personal relationships, decisions made by buying committees. An online survey rarely reaches the person who actually decides.
What only a conversation delivers
A relaxed, confidential conversation creates an atmosphere in which people open up. You can ask follow up questions, react to undertones and dig deeper when it gets interesting. That is where the statements come from that never appear in a questionnaire.
Towards the end of our interviews we hear one sentence again and again: “Let me tell you something I would not normally say.” It does not come in minute five. It comes once there is trust. No form in the world creates that moment.
| Survey | Personal interview | |
|---|---|---|
| Output | numbers on questions known in advance | reasons, connections, new questions |
| Honesty | socially desirable answers | openness, if the interviewer is neutral |
| Follow up | not possible | at any time |
| Reach in B2B | often assistants or clerks | the decision makers, by design |
| Strength | trends across many responses | causes and ideas |
Why you should not interview your customers yourself
The most common mistake is not the method. It is the sender. When your own sales team calls, customers are either on the defensive or in negotiation mode. They protect the relationship or use the opportunity for the next discount. An open conversation about what is good, bad, different or better does not happen that way.
Honesty needs neutrality. Someone without commission, targets or history with the customer gets answers your sales team never hears.
Whom to interview
How many conversations you need depends on the goal. A pricing question needs different interviewees than a brand repositioning. We have run worldwide phone interviews as well as on site conversations at customers. What matters is the mix:
| Group | What you learn |
|---|---|
| Current customers | why they stay and what would make them switch |
| Prospects and non customers | why they do not buy (yet) |
| Former customers | the real reason they left |
| Employees | what is known internally but never reaches the top |
| Suppliers and sales partners | how the market sees you from outside |
| Former employees | what they can say openly today |
Two sentences that surprised management
The key account. “We have been one of your three largest customers for six years. The last time anyone visited us was three years ago.” The sentence did not come up in the annual review with sales. It came up in the confidential interview.
The tool trolley. A STAHLWILLE dealer said in an interview that he could not understand why STAHLWILLE of all companies did not offer a configurator for tool trolleys. Nobody was better placed to do it. STAHLWILLE took the hint seriously. It became a concept, it was implemented, and a year later the tool trolley configurator had become a strong revenue driver. A simple remark from a sales partner. Without a neutral conversation it would never have been made, or it would have got lost in sales.
What this means for you
- Use surveys for trends, not for causes.
- Have interviews run by a neutral person, not by sales.
- Also talk to those who did not buy or who left.
- Expect the most valuable statements to be ideas, not criticism.
FAQ
Do online surveys work in B2B?
For trends across many customers, yes. For why customers buy, stay or leave, no. That needs personal interviews with follow up questions.
How many interviews does B2B customer research need?
It depends on the goal: pricing, brand perception and lost deals need different interviewees. The mix of customers, non customers and former customers matters more than the number.
Why should sales not interview customers?
Because customers are never neutral towards sales. They protect the relationship or negotiate. A person without a stake gets honest answers.
Whom should you interview besides customers?
Prospects, former customers, employees, suppliers and sales partners. Sales partners in particular often see opportunities nobody inside has on the radar.
