The Best Way to Do Your Win/Loss Customer Interviews in 2025
Jan 2 • 6 min readRegardless of whether you are working through your first sales or already gained traction on the market, you need a continuous improvement process that helps you improve your sales strategy. This is one of the critical factors behind successful businesses - increasing their learning rate. Thriving companies embrace every opportunity to complement their understanding of their customers’ problems and needs.
Conducting a win/loss analysis is an excellent opportunity to increase your learning rate by identifying trends and blind spots in your sales process. By the end of this article, you know what is the best way to improve your sales cycles by gathering win/loss data.
What are Win/Loss Interviews?
A win-loss interview happens after your interaction with a potential customer is completed, regardless of whether it was successful (win) or not (loss). The goal of the interview is to capture key moments from the sales process and extract insights about improving the win rate.
This type of interview is a powerful way to understand your customer's complete experience with your brand and, most importantly, what influenced their buying decision.
Why are Win/Loss Interviews Important?
This question has two sides - why are the interviews with lost customers important, and why are the interviews with won customers important?
Based on the feedback from lost deals, your goal is to improve your sales tactic so you can increase your win rate. Potential insights that such interviews can uncover are:
- Mismatches between initial product positioning and what was discovered during the interview
- Deal breakers
- Important stakeholders in the decision-making process who can veto your deal and their interests
- Existing alternatives to your product and how
The interviews with customers who decided to continue with your product can inform you of:
- Stakeholders that champion your product
- Your unfair advantages and unique value proposition or, in other words - where your product excels ahead of the competition
- How to retain your customers through understanding what value they expect from it
Interview Preparation
When executed correctly, interviews can yield invaluable insights. However, an interview is much more than a “casual conversation” with your prospect. Professional researchers follow a well-developed methodology that ensures interviews are conducted confidently. Here are the key steps for effective win/loss research in a nutshell.
1. Define Clear Objectives
The objective is the purpose of your research. For a meaningful objective, it needs to lead to improvement in your sales, marketing, or product management strategy.
2. Select the Right Participants
The power of the Win/Loss interviews is that they include a diverse range of customers and provide a holistic overview of your brand experience. Make sure you include representatives of all customer segments that you target with a wide range of demographics.
Timeliness is an essential factor for efficient interviews - make sure to talk with people who interacted with your company no later than the last three months, ideally up to a month. Beyond this period, it will be harder to extract and capture important nuances and emotions from the interviewee's situation.
3. Prepare interview script
The difference between a casual conversation and a well-conducted interview is having an interview script to follow. An interview script ensures that the conversation covers all topics of interest and is conducted in relatively the same context. This ensures that responses can be aggregated and compared across different interviews.
Having a prepared set of questions also ensures that the questions you ask are well-defined and will not mislead or guide respondents to specific answers. Preparing a well-thought-out interview script is a separate topic on its own. If you are interested in that, skip to the last paragraph of this article.
4. Set Up the Scene
The interviewee is dedicating part of their precious time to share their experience with you. Make sure they know you appreciate that and their opinion is valued.
Create a scheduling process that works for your respondents. Giving them the option to pick the time and place (including online) to have the conversation will significantly improve your response rate.
5. During the Interview
Remain neutral, record (after taking permission), and take notes. Your goal during the interview is to extract as much information as possible - you are not here to revert their decision if they decide not to buy your product. Also, make sure you are not starting a debate and trying to prove them wrong for anything. Their point of view is theirs, and your job is to understand it as deeply as possible.
In other words, try to stick to your interview script as much as possible.
6. Analyze and Synthesize Insights
Once you have conducted several interviews, you will start seeing patterns. These are the insights you are looking for from your research that needs to be aggregated and summarized.
