Before you reach out
Which email should I use? 
Use support@weishengretail.com for general questions, existing customer support, and product enquiries. For multi-store rollouts, partnerships, or anything enterprise-sized, email wujingjun@weishengretail.com directly.
Do you have a phone number?
Yes — +852 0000 0000, Mon–Fri 9:00–18:00 HKT. For complex briefs, email works best because it gives us time to put together a real answer instead of rushing you off the phone.
Can I visit your office?
By appointment. Our showroom in Tsim Sha Tsui East has a small range of props and a working demo of the Vision Retail OS app. Email us with your preferred date and we'll confirm.
Where can I report a bug in the app?
Use the contact form with subject "Mobile app" or email support@weishengretail.com. Please include your device model, OS version, and a screenshot if possible. We triage app bugs daily.
