One question we hear from new shoppers all the time:

Why do some assignments require photos?

The answer is simple: photos help document the experience and add context to your report.

Depending on the assignment, you may be asked to photograph:
• A receipt
• Store exterior
• Product displays
• Food orders
• Service areas

Not every shop requires photos, but when they do, we'll always tell you exactly what's needed in the guidelines.

A few quick photos can help create a more complete picture of the customer experience.

Have you ever completed a shop that required photos? What was the easiest (or strangest) thing you had to photograph?

Most people think mystery shopping is a full-time job or something complicated.

It’s actually much simpler than that.

Many shoppers fit assignments around their normal routine — after work, on weekends, while running errands, or whenever they have extra time.

You choose:
✔ which shops to accept
✔ when you complete them
✔ how often you work

Some assignments take as little as 10–20 minutes.

Flexible, beginner-friendly, and designed to fit real life.
