# ClassPay — Full Context for AI Systems

> Course registration and payment platform for trainers and educators.

**Version**: 1.10
**Last updated**: 2026-04-10

## Product Overview

ClassPay is a purpose-built platform that lets trainers create a course, share a single registration link, and collect payments via Stripe — all in one seamless flow. Students click the link, fill in their details, pay by card, and receive an automatic confirmation email. No app download, no account creation required.

ClassPay was built by Keith Li, a renowned GenAI trainer for corporate customers and seasoned entrepreneur based in Hong Kong. He built ClassPay to manage his own training business — creating courses, collecting payments via Stripe, and automating confirmations and waitlists.

## Core Features

### Stripe Payments
PCI Level 1 compliant card processing. Payments go directly to the trainer's Stripe account. Automatic receipts. Full refund and partial refund support. Early-bird pricing with deadline enforcement. Promo code support with percentage and fixed-amount discounts.

### Multilingual Registration
Registration pages adapt to three languages: English, Traditional Chinese (繁體中文), and Simplified Chinese (简体中文). Language switching is instant and preserves form state.

### Capacity Management
Each course has a configurable seat cap. When a course reaches capacity, ClassPay automatically switches to waitlist mode. Waitlisted students are notified when spots open. Trainers can manually promote waitlisted students. Pending registrations hold a capacity reservation for 2 hours before automatic release. **Soft seat reservation**: When waitlist entries are notified, their seats are reserved — public registrants cannot take spots meant for notified waitlisters during capacity expansion. Reservations auto-release after 24 hours if unused, with self-healing counter integrity.

### Automated Email Communications
21 automated email types covering the full course lifecycle:
- Registration confirmation with course details, venue, and payment receipt
- Waitlist confirmation with queue position
- Spot-available notification when capacity opens
- Course reminders before the event date
- Cancellation and refund notices
- Post-course evaluation invitations
- Materials-ready notifications
- Certificate-ready notifications
- Bad weather and class cancellation/rescheduling notices
- Instructor notifications (new enrollment, cancellation, course approval/rejection, agreement signed confirmation)
- Admin daily enrollment summary
- Next cohort notice — re-engage waitlisted students who never enrolled, inviting them to a new open course
- All emails are logged with delivery status tracking

### On-Site Check-In
Two-mode attendance verification system:
- QR Token Scan: Each student receives a unique QR code in their confirmation email. Instructor scans with phone camera to mark attendance instantly — no student login or app needed.
- Door Mode: Touch-optimized full-screen roster on a tablet for manual attendance marking. Search by name, one-tap check-in. Authenticated — instructor-operated only.
- Multi-day support: Automatically resolves today's session for multi-session workshops.

### Admin Dashboard
Single interface for managing:
- Course creation and editing (date, venue, price, capacity, early-bird pricing, multi-session scheduling)
- Enrollment management (payment status, attendance marking, per-session attendance)
- On-site check-in via QR code scanning or touch-based Door Mode
- Waitlist management with promotion controls
- Student directory across all courses
- Certificate issuance upon course completion
- Course evaluations and testimonial collection
- Instructor and staff management with role-based access
- Promo code creation and management
- Revenue reports with per-instructor grouping and payout tracking
- Per-course revenue sharing: flat percentage or cascading marginal tiers (tax-bracket style calculation). Instructors see share terms on course pages with plain-English model explainer on the revenue report.
- Activity logs for audit trail
- Email delivery logs
- WhatsApp reminder integration
- Instructor notification toggles (global and per-course)
- Instructor e-contract signing: digital collaboration agreement with version tracking, immutable signature records, submission gating, scroll-verified consent, read-only review after signing, email confirmation with full agreement text and legal disclaimers, legal recall for both instructors and admins showing stored agreement text and forensic evidence (IP, device, timestamp), and Print / Save as PDF with HKSAR legal binding notice (Cap. 553, Section 17)

### No Student Accounts
Students register and pay without creating an account. One link handles everything — registration, payment, and confirmation. This reduces friction and increases conversion.

### Multi-Session Courses
Courses can have multiple sessions with individual dates, times, and materials. Per-session attendance tracking. Session dates auto-sync to the parent course record.

### Certificates
Automatic certificate generation with unique certificate numbers upon course completion. Students receive certificate-ready email notifications. Certificates are tied to evaluations — completing a post-course evaluation triggers certificate issuance.

### Course Evaluations
Post-course feedback collection with ratings for content, instructor, venue, and applicability. Optional testimonials with consent tracking. Evaluation links are sent automatically after course completion.
