Do you want to know how your service really performs in practice? The Mystery Shopper (Secret Client) method gives you a true picture of the customer experience exactly as your clients experience it daily. Not based on hearsay, but through clearly defined criteria, scenarios, and measurable indicators.
In practice, a mystery shopper is a trained person who acts as a regular customer/user and goes through a pre-defined process: visiting the location, interacting with employees, making a purchase or inquiry, using the service, calling the call center, or contacting via social media or website. Throughout the interaction, communication quality, procedure compliance, speed, friendliness, accuracy of information, cleanliness, and overall impression are evaluated.
On the other hand, a secret client is a broader concept, often different from traditional “shopping”. It can also involve testing business processes: how inquiries are handled, response times, compliance with internal procedures, document handling, promises made to customers, and whether they are fulfilled. Secret client services are frequently used in B2B, complex product sales, institutions, and whenever you want to test the system’s reliability and professionalism, not just counter courtesy.
This method is particularly useful when everything seems fine “on paper,” but results, sales, or customer impressions fall short. The mystery shopper/secret client does not aim to catch someone “in the act,” but to show where the system fails and what needs improvement to make the service better, sales more efficient, and customers more satisfied. Often, minor details that make a big difference are discovered: how questions are asked, tone of communication, reaction speed, inconsistent information, gaps in procedures, or varying standards across locations and teams.
How does a mystery shopper / secret client study work?
First, we define the goal together: exactly what we measure and at which process points. Then, scenarios are created (e.g., product inquiry, complaint, interest in a premium package, service issue) and a list of criteria for evaluating each visit or contact. If needed, scenarios can include multiple steps: first contact, follow-up call, branch visit, or final process stage (delivery, payment, complaint). After completion, you receive a clear report with ratings, situation descriptions, and improvement recommendations.
Advantages of mystery shopper / secret client:
- Real picture of the service without embellishment or staff “preparation”
- Assessment of communication quality and customer relations
- Verification of procedure and standard compliance in practice
- Detection of weak points in sales, service, and support
- Comparable results across locations, teams, or shifts
- Detection of inconsistencies (different information, standards)
- Concrete step-by-step recommendations for improvement
- Possibility of repeating studies and tracking progress over time
Mystery shoppers are ideal for retail, hospitality, banks and insurance, telecoms, customer support, public institutions, healthcare, and any company dependent on service quality and employee behavior. Secret clients are especially useful for testing process flow and system reliability, i.e., how inquiries are handled, deadlines met, quality of communication, and promise fulfillment. Studies can be conducted at a single location or multiple sites, once or periodically, depending on your goals.
In the end, you get what matters most: clear, measurable, actionable information—where you excel, where you lose customers, and exactly what to do to improve the experience. If desired, we can define the scenario and criteria together in the first conversation so you immediately know what is measured and what results you will receive.
