TipFlow

Cashless tips that reach the right person instantly.

TipFlow is a QR-based cashless tipping platform for service businesses where customers choose a specific worker, tip by card or digital wallet, and get an instant payment confirmation. It serves merchants like restaurants, salons, barbershops, hotels, valet services, and other tip-enabled businesses that want transparent tip distribution, better staff motivation, and simple administration.

  • Display merchant branding, venue name, and location text.
  • Handle invalid or stale links with a friendly retry message.
  • Preload employee data to minimize delay after scan.

2. Choose Employee

  • If a worker is inactive or unavailable, hide them from the list or mark them unavailable.

  • Shift-based employee visibility and scheduled availability.
  • Refund and reversal handling with clear ledger adjustments.
  • Multi-location merchant support under one account.
  • Localization for Arabic and English, including right-to-left UI support.
  • Offline QR fallback page with support contact and retry messaging.

Fast, Trustworthy, Mobile-First UI

  • Large tappable employee cards optimized for one-handed mobile use.
  • High-contrast typography and accessible color choices that meet WCAG 2.1 AA.
  • Persistent loading skeletons and progressive data loading to keep perceived speed high.
  • Clear payment trust cues such as secure checkout labels and wallet icons.
  • Accessible forms with screen reader labels, focus states, and error text near fields.

A customer walks into a salon, finishes their service, and wants to leave a tip without asking for cash. They scan the QR code at the front desk, see the salon name, and choose the stylist who helped them from a photo-based staff list.

They pick a tip amount, tap Apple Pay, and receive an instant confirmation. The stylist sees the tip in real time, while the salon owner sees the transaction in the merchant dashboard with the employee name, amount, rating, and payout status.

Over time, the salon reduces awkward cash handling, employees trust that tips are attributed correctly, and the owner gains visibility into service quality and staff performance. The result is faster checkout, happier staff, and a more modern customer experience.

Technical Needs

  • Backend API built with Node.js and TypeScript.
  • Primary database in PostgreSQL with row-level tenant separation by merchant.
  • Redis for session state, idempotency keys, and short-lived checkout state.
  • Object storage such as AWS S3 for logos, profile photos, and exported reports.
  • Event tracking pipeline using Segment or PostHog.
  • Role-based access control with secure session management and audit logging.

Integration Points

  • Twilio for SMS receipts and optional phone verification.
  • SendGrid or Postmark for email receipts and notifications.

  • Auth0, Clerk, or Supabase Auth for merchant admin sign-in.

Data Storage & Privacy

  • Separate merchant data by tenant and enforce access controls on every API request.

  • Use async webhook processing for payment confirmation and ledger updates.
  • Support high read traffic at venues with bursts during meal rushes by using CDN caching for public pages.
  • Design dashboard queries with indexed filters for merchant, location, date, and employee.

Potential Challenges

  • Employee attribution errors if the customer selects the wrong person; mitigate with clear photo cards and confirmation before payment.
  • Payment wallet availability varies by browser and device; mitigate by dynamically showing supported methods and fallback card entry.
  • Merchant onboarding complexity across many venue types; mitigate with templates and guided setup by business category.
  • Payout reconciliation issues from processor webhook delays; mitigate with idempotent event handling and retry queues.
  • Multi-language support for English and Arabic could introduce layout issues; mitigate with RTL testing and localized UI components.

Build a mobile-first cashless tipping platform called TipFlow.

Product summary:
Customers scan a merchant QR code, land on a branded mobile web page, choose a specific employee to tip, select a tip amount and optional rating, then pay using card, Apple Pay, or Google Pay. The chosen employee receives instant attribution in the system, and the merchant gets a dashboard to manage staff, view transactions, monitor payouts, and export reports.

Core screens and flows:
1. Public QR landing page for a merchant/location
2. Employee selection screen with photo, name, role, active/inactive status
3. Tip amount and rating screen with presets and custom amount
4. Secure payment checkout with Stripe, Apple Pay, and Google Pay
5. Success/receipt screen with share and receipt options
6. Merchant admin login
7. Merchant dashboard with totals, employee performance, transaction list, payout status, and exports
8. Staff management screen to add/edit/deactivate workers
9. QR code generator and download page for merchant locations

Data model:
Merchant(id, name, logoUrl, locale, currency, status)
Location(id, merchantId, name, address, qrCodeToken, status)
Employee(id, merchantId, locationId, name, role, photoUrl, active, sortOrder)
TipTransaction(id, merchantId, locationId, employeeId, amount, currency, rating, comment, paymentProvider, providerPaymentId, status, createdAt)
Payout(id, merchantId, employeeId, amount, status, providerPayoutId, createdAt)
AuditLog(id, merchantId, actorId, action, metadata, createdAt)
User(id, merchantId, role, email, authProviderId)

Technical stack:
Use Next.js with React and TypeScript for the frontend and app router. Use Node.js/TypeScript API routes or a separate NestJS backend. Use PostgreSQL with Prisma. Use Redis for ephemeral checkout session state and idempotency keys. Use Stripe for payments and webhooks. Use Auth0 or Clerk for merchant authentication. Use Tailwind CSS and shadcn/ui for the interface. Use PostHog for analytics and Sentry for error monitoring. Use AWS S3 for image and QR storage.

Build requirements:
Implement a mobile-optimized public tipping flow with no app install. Support English and Arabic with RTL layout. Make the checkout fast, accessible, and PCI-safe by using hosted payment elements. Add merchant role-based access control, audit logs, analytics events, and CSV export. Include webhook handling for payment success, refunds, and payout updates. Seed demo data for a coffee shop, salon, and valet location. Use clean component structure, responsive layouts, and realistic empty/error states. Generate a polished admin dashboard and checkout UI that is production-ready and easy to extend.

Business Idea

I'm building a system of cashless tipping, three types of people are involved: the merchant who provides a service via his venue, the worker who gets the tips, and the merchant's client who gives the tip (tipper). Our solution flow is: the tipper scans a QR code, then a web page opens to show the merchant's name and his employees, then the tipper chooses which employee he wants to tip, and then he proceeds to the payment amount and rating, then he proceeds to the payment page, and pays by card, Apple Pay, or Google Pay. The tip will arrive instantly to the chosen employee. The merchant will have a dashboard that shows everything and enables him to control everything. Targeted Merchants types are: Coffee shops, restaurants, and food & beverage service staff Men's barbershop staff Jordanian women's salon and beauty center staff Foreign (Filipino) women's salon and beauty center staff Spa and massage center staff Valet parking staff Hotel porters Airport porters Car wash staff (Egyptian nationality) Supermarket baggage handlers Taxi and ride-hailing app drivers Butchers Bus drivers Cleaning service providers Any service provider who accepts tips.
