Knowing how to prepare for a mystery shopping assignment can make the difference between a successful evaluation and a rejected report. Whether you're visiting a restaurant, retail store, apartment community, or automobile dealership, preparation is one of the most important parts of mystery shopping.
Over the years, I've learned that many mistakes can be prevented before you ever leave home.
Forgetting an assignment requirement, visiting at the wrong time, or failing to understand your customer scenario can create problems that are difficult to correct afterward.
Here are some steps I recommend taking before heading out on your next mystery shopping assignment.

Before accepting an assignment, review the requirements to make sure you understand what's expected.
After accepting it, read the instructions again.
Pay particular attention to the location, date, permitted visiting hours, required purchases, employee interactions, and reporting deadline.
Some restaurant assignments require ordering specific menu items. Apartment evaluations may require asking about particular floor plans. Automotive assignments might involve discussing financing or taking a test drive.
Missing one required step could invalidate the assignment.
If something isn't clear, contact your scheduler before making the visit.
Some mystery shopping assignments require you to act as a potential customer with a particular background or reason for visiting.
Make sure your story makes sense.
I once completed a new home builder assignment where I told the sales consultant that I wanted to purchase a house as a surprise for my wife.
I thought it was a reasonable explanation.
Unfortunately, the salesperson didn't believe my story and reported to a supervisor that they suspected a mystery shopper.
That experience taught me an important lesson.
When an assignment requires a customer scenario, understand it thoroughly and make sure your responses are believable.
Don't unnecessarily complicate your story. If the salesperson asks questions, your answers should remain consistent.
Some assignments also require you to use an alternate name or telephone number. Review those details before entering the business.
Forgetting your assigned identity during the conversation can quickly raise suspicion.
Confirm the business address and make sure you're visiting the correct location.
Some companies operate multiple stores or offices within the same community.
Check the business hours and determine how long it will take to reach your destination.
If the assignment requires an appointment, confirm the details according to the company's instructions.
Don't assume that every location follows the same schedule.
Also, avoid contacting the business beforehand unless the assignment permits or requires it.
Before leaving home, gather everything you'll need as you prepare for a mystery shopping assignment.
Depending on the assignment, this might include:
Make sure your phone has enough battery power for photographs, directions, and any other permitted uses.
If the assignment requires a purchase, verify the reimbursement limit before spending money.
Remember that reimbursement and shopper compensation are not necessarily the same thing.
Mystery shopping requires paying attention to details that ordinary customers might overlook.
Before the visit, review the important observations you'll need for your report.
These might include employee greetings, names, product knowledge, cleanliness, customer service, and whether the employee follows required procedures.
Some assignments require recording the time you entered the business, how long you waited, or when an employee approached you.
Understanding these requirements beforehand makes it easier to remember important details.
However, don't become so focused on memorizing questions that you stop acting like a natural customer.
One of my favorite preparation habits is reviewing the report questionnaire before completing an assignment.
When you know what questions you'll be answering afterward, you'll have a better understanding of what to observe.
Some reports require only a few answers. Others involve detailed narratives, photographs, and specific timing information.
Make sure you understand how much work is involved.
After completing the visit, find an appropriate place to record your observations while they're still fresh.
Don't wait until the following day to reconstruct an entire conversation from memory.
Rushing can lead to mistakes.
Allow sufficient travel time, especially when visiting unfamiliar locations or completing assignments during busy periods.
Make sure your schedule allows you to complete the entire interaction without leaving early.
If you're completing several mystery shops in one day, leave enough time between assignments to organize your notes and avoid confusing details from different visits.
Before walking out the door, ask yourself:
If you can answer these questions confidently, you're better prepared for the assignment.
Learning how to prepare for a mystery shopping assignment becomes easier with experience.
You develop routines, recognize common requirements, and become more comfortable interacting with employees.
However, even experienced shoppers should never skip the preparation process.
Every mystery shopping assignment is different, and requirements can change from one client to another.
The time you spend preparing before leaving home can save you hours of frustration afterward.
A little preparation can help you complete better reports, avoid unnecessary mistakes, and build a stronger reputation with mystery shopping companies.
Video assignments require additional preparation. If you're planning to record an evaluation, read our guide on How to Prepare for a Video Mystery Shop for equipment and recording tips.
