Mystery shopping guide: how to run it in Africa

When mystery shopping is the right tool

Use it when you want to know what staff actually do, not what customers remember. Banks use it to check branch and agent service, telecoms to check shops and care lines, retailers to check stock, price display and queues, and fuel and food chains to check hygiene and speed.

It does not replace a customer satisfaction survey. A survey tells you how people feel. A shop visit tells you what happened.

Step 1: decide what you will measure

Write a short scorecard of things a shopper can see or time. Typical items are greeting within a set time, wait time, whether the staff member explained the offer correctly, whether the correct price was quoted, cleanliness, whether the shopper was offered an extra product, and how a complaint was handled.

Keep the scorecard to what is observable. Do not ask shoppers to judge feelings or guess intentions.

Step 2: write scenarios

Give each shopper a short scenario: what to ask for, what to say if asked a question, and what to do if something goes wrong. Use the same scenarios in every location so results compare. Rotate scenarios across visits so staff do not recognise a pattern.

Step 3: recruit and train shoppers

Shoppers should look like ordinary customers, speak the local language and be trusted to report honestly. Train them on the scorecard, on timing, on remembering details and on what they must never do, such as breaking the law, pressuring staff or recording where it is not allowed.

Step 4: run visits and calls, in person or remote

Where you have shoppers on the ground, visits can be done in person. Remote options work well and cost less: mystery calls to customer care, chats on WhatsApp or Telegram with a business, tests of a website or app, and checks of an online order from ordering to delivery.

Step 5: check quality

Check every report. Look for impossible timings, copied text and gaps. Ask shoppers to submit timestamps, and where lawful and agreed, receipts or screenshots. Re-visit a share of locations to confirm scores.

Ethics and law

Tell staff in advance that mystery shopping is part of how the business checks quality, even if you do not say when. Never use it to entrap staff or to get them disciplined for a single bad answer. Check the data protection rules that apply before recording any voice or image, and keep personal details out of reports.

Reporting

Report scores by location, by item and over time. Show the best performers as well as the worst, and write what good looks like. A report that only lists failures makes staff defensive. A report that shows strengths and gaps changes behaviour.
