Mystery Shopping & Performance Audits

Mystery Shopping, aka Customer Service Auditing or Integrity Shopping is a valuable business tool for monitoring customer service, employee performance, honesty, adherence to company policy, as well as, an aid in loss prevention. With today's social networks one bad experience (customer service, security, meal, rental, repair, etc) can literally cost you hundreds of prospective clients. One rude or dishonest employee can cost you thousands of dollars in revenue.

Video Mystery Shopping records the interaction with your staff and can be used not only as a teaching tool, but also to reward good customer service and to spot problems with safety, sanitation, building maintenance and security.

This type of service is beyond the scope of traditional shopping services and should only be done by a Licensed Private Investigation agency and only with the informed consent of your employees that they will be subject to videotaping and/or recording while on your premises. Nevada for example, mandates that only licensed private investigators or their registered employees, can do mystery shopping of any kind. The biggest advantage to using a P.I. firm is professionalism. You are guaranteed to get an agent that is impartial and accustomed to paying attention to fine detail.

Some businessses that use this type service are Banks, Department Stores, Convenience Stores, Security Contractors, Hotels, Restaurants, Car Dealers, Car Rental Agencies, Personal Care Facilites, Apartment Complexes, New Home Builders, Fitness Centers, Health Services, Automotive Repair Shops, Bars & Nightclubs, Entertainment Venues, Sports Facilities...virtually anywhere that involves interaction with the pubilc and/or handling of cash by employees.
