DIGITAL TIPPING PLATFORM “XXXX” — WEB APP + BACKEND + PAYMENTS INTEGRATION
Budget: $3,000 – $5,000 USD
Project Goal
Build a digital tipping service where customers scan a QR code at a bar/restaurant/shop, open a payment page, choose a tip amount, and pay via Apple Pay, Google Pay, Visa, Mastercard. Tips accumulate and are paid out to the recipient when a minimum threshold (e.g., €100) is reached.
Core Features (MVP)
1) Customer Flow (no login)
* Scan QR → open mobile tipping page
* Show venue/staff name + suggested amounts (€1/€2/€5/€10) + custom amount
* Pay with Apple Pay / Google Pay / cards
* Confirmation screen + optional email receipt
* UX must be fast (<10 seconds)
2) QR System
* Unique QR codes for:
* Venue (team pool)
* Individual staff
* Short secure links (e.g., xxxx.com/t/{token})
* Ability to regenerate/revoke QR
3) Dashboards
* Staff: balance, tip history, payout status
* Venue: create staff, reports, CSV export
* Admin: manage users, transactions, disputes, settings
4) Payout Logic
* Tips stored in recipient wallet
* Payout only when balance ≥ threshold (default €100)
* Status: pending → processing → paid
* Automated payouts if provider supports it
STAFF OR RESTAURANTS: when registering to our website or webapp will receive a QR code, where the tip will be paid to (linked to a IBAN bank account)
Payment Integration
A. Stripe
* Apple Pay / Google Pay + cards
* Stripe Connect for recipients
* Webhooks + automated payouts
Tech Requirements
Frontend
* Mobile-first web app / PWA
* React or Next.js (preferred)
* Fast, simple UI
Backend
* Node.js (Express/Nest) or Python (FastAPI)
* REST API
* Webhooks for payments
* Cron for threshold payouts
* Role-based access (staff/venue/admin)
Database
* PostgreSQL/MySQL
* Entities: Users, Venues, Staff, TipLinks, Transactions, Payouts
Security
* HTTPS, rate limits, secure tokens
* GDPR basics
* Logging & monitoring
Deliverables
1. Working web app + dashboards
2. Payment integration with webhooks
3. QR generation system
4. Threshold payout logic
5. Git repository + docs
6. Deployment to production
