Quick answers
Do customers need an app?
No. Tap or scan opens a mobile web page. Zero installs for you or your customers.
How are referrals tracked?
Each referral link is unique. When a referred friend converts, the referrer is automatically attributed.
Can I run rewards?
Yes — discount codes, credits, gift cards. Rewards fire automatically on conversion, or you handle them manually.
Which CRMs do you support?
HubSpot today. Salesforce next. CSV export on all plans. Zapier/webhooks for everything else.
What's attribution?
You know which customer referred which new customer, from which source (NFC/QR/link), at which location — every time.
Is my data secure?
Data is encrypted in transit and at rest. You control all integrations. GDPR and CCPA-friendly.
