Quick answer
Ask 3–5 short questions within a day of the purchase — one rating ("How likely are you to recommend us, 0–10?"), one "What did you like?" and one "What should we improve?". Use a free Google Form linked from WhatsApp or a QR code. Read every answer weekly, fix the top complaint each month, and tell customers what you changed. Keep feedback surveys separate from Google review requests: ask everyone for a Google review the same way, regardless of their survey answer.

Customers who are unhappy rarely tell you — they just don't come back. A short feedback survey gives them an easy way to speak, and gives you specific things to improve. It also shows customers you care, which builds loyalty.
When to ask
| Business | Best time |
|---|---|
| Restaurant/café | Same evening |
| Retail | Within 24 hours |
| Repair/home service | After the job is confirmed working |
| Clinic | Next day (never during treatment) |
| Coaching | Monthly and at course end |
| Hotel | At checkout or next day |
The 15 best questions (pick 3–5)
Overall
- How likely are you to recommend us to a friend? (0–10)
- Overall, how satisfied were you? (1–5)
- Did we meet your expectations?
What works 4. What did you like most? 5. Which product/service did you use? 6. How did you hear about us?
What to fix 7. What's one thing we should improve? 8. Was anything disappointing? 9. How was the waiting time?
Specifics 10. How was the staff behaviour? 11. How was the cleanliness? 12. Was the price fair for the quality? 13. Was it easy to find us / book / pay?
Future 14. What else would you like us to offer? 15. Can we contact you about your answer? (phone optional)
Net Promoter Score (NPS) in simple words
Ask: "How likely are you to recommend us?" (0–10).
- 9–10 = promoters (fans)
- 7–8 = passives
- 0–6 = detractors (unhappy)
NPS = % promoters − % detractors. Track it monthly; the trend matters more than the number.
Tools
- Google Forms: free, mobile-friendly, results in a sheet. See Google Forms for small business.
- WhatsApp: send the form link with a thank-you message.
- QR code on the bill or table linking to the form.
- Paper cards for older customers.
Feedback vs Google reviews — keep them separate
Don't send only happy survey respondents to Google and hide the unhappy ones — that's "review gating", which Google's policy prohibits. Instead:
- Ask every customer for a Google review the same way (review link guide).
- Use the survey to fix problems, contacting detractors personally.
Turning feedback into action
- Weekly: read all answers; tag themes (wait time, price, staff, quality).
- Monthly: pick the top issue; make one change.
- Close the loop: reply to people who left contact details: "You told us the wait was long — we've added a second counter on weekends."
- Share wins: post improvements on Google and Instagram.
Sample WhatsApp message
"Thank you for visiting [Business]! Could you answer 3 quick questions to help us improve? It takes 30 seconds: [form link] 🙏"
Sample 5-question survey for a restaurant
- How would you rate your meal today? (1–5)
- How was the service speed? (Fast / OK / Slow)
- Which dish did you enjoy most? (short answer)
- What one thing should we improve? (short answer)
- How likely are you to recommend us to a friend? (0–10)
Keep it under a minute. Every extra question cuts responses.
Reading the results
- Net Promoter Score (NPS): % of 9–10 scores minus % of 0–6 scores. Above 30 is good for a local business; above 50 is excellent.
- Patterns over single answers: one complaint about parking is noise; ten is a priority.
- Positive words: note the phrases customers use ("homely taste", "quick delivery") — use them in your posts and profile description.
Close the loop
Message people who gave low scores: "Thanks for your honest feedback — we've changed ___ because of you." Customers who see their feedback acted on often become your most loyal regulars.
Feedback vs Google reviews
Private surveys catch problems early; Google reviews build public trust. Never use a survey to filter who gets asked for a Google review ("review gating") — Google prohibits it. Ask everyone for an honest review using your review link, and use surveys separately to improve.
How often to survey
Monthly for restaurants and salons, after every job for home services, and once per term for coaching institutes. Rotate questions so regulars don't get bored.
Collecting feedback offline
Not every customer will fill a form. A tablet at the billing counter, a printed card with three smiley faces, or a quick "How was everything today?" from the owner while packing the order all count. Write down what you hear in the same sheet as online answers so nothing gets lost.
Frequently asked questions
How many questions is too many?
More than 5 for a quick purchase. Keep it under a minute.
Should surveys be anonymous?
Optional contact details let you fix problems personally; anonymous answers are often more honest. Offer both.
Can I offer a discount for filling the survey?
For a private survey, a small thank-you is fine. Never offer anything for Google reviews.
What if the feedback is harsh?
Thank them. Harsh feedback is free consulting.
