Over the past three editions, we’ve covered retention, sync, and push. This time, we unveil the ultimate engine—replacing guesswork with real customer feedback to create blockbuster products.
 
“I want to launch a new herbal tea, but what do my customers actually want?” Rely on gut feeling? Ask the staff? Why not just ask the people who actually pay you?
 
eRun Membership System | Engine #4: Interactive Feedback Engine

 
Turn feedback into priceless insights—at low cost, yet yielding direction that money can’t buy:
 

• After purchase, auto-push a quick survey (e.g., “What’s your top health concern right now?”: Heat-clearing / Dampness relief / Poor sleep)
• Survey completion instantly rewards a $5 cash voucher or double points—driving sky-high response rates
• Backend auto-tabulates which remedies are most requested and which time slots see the highest demand
• Also push health tips with soft offers—e.g., “The weather’s humid and hot—remember to drink our Five-Flower Tea,” paired with a voucher to gently drive visits

 
Herbal Tea Shop Case Study:

 
After buying herbal tea, customers scan a QR code on their receipt to give feedback and receive a $5 voucher. Result: over 40% of customers selected “poor sleep quality.” The shop immediately developed a “Soothing Mulberry Tea” with limited-time trial vouchers—and the new product flew off the shelves the moment it launched.
 
No more guessing—customers tell you exactly what they want, while you boost repurchase at the same time.
