How TicketQ Works

A comprehensive ticketing platform supporting both lottery-based and direct purchase systems

What is TicketQ?

TicketQ is a modern ticketing platform that supports two distinct purchasing models: lottery-based entries for high-demand events and traditional direct purchases.

Lottery System

Fair allocation system for high-demand events. Users enter a lottery with payment, and winners are randomly selected.

  • Fair random selection
  • Automatic refunds for losers
  • Prevents bot purchases

Direct Purchase

Traditional first-come-first-served ticket sales for regular events with immediate confirmation.

  • Instant ticket confirmation
  • Real-time availability
  • Standard e-commerce flow
Feature Lottery System Direct Purchase
Best For High-demand, limited events Regular events with good availability
Selection Method Random draw First-come-first-served
Payment Timing Pay to enter, refund if not selected Pay only when purchasing
Confirmation After lottery draw Immediate
Fairness Equal chance for everyone Fastest connection wins

Lottery System Flow

How the lottery-based ticket allocation works for high-demand events

1
Event Created with Lottery

Organizer creates an event and enables lottery mode. Sets lottery entry period and draw date.

2
User Enters Lottery

Users pay full ticket price to enter lottery. Payment is processed but held for verification.

3
Entry Period Closes

Lottery entry period ends. No more entries accepted. System prepares for draw.

4
Lottery Draw

Random selection algorithm picks winners based on available tickets. Fair and transparent process.

5
Winners Get Tickets

Selected users receive their tickets. Payment is confirmed and tickets are generated.

6
Automatic Refunds

Non-selected users receive automatic refunds through Stripe. No manual intervention needed.

Fair & Secure

Cryptographically secure random selection ensures fairness for all participants.

Automatic Refunds

Instant refunds for non-winners through Stripe's payment processing system.

Equal Opportunity

Every participant has an equal chance regardless of internet speed or timing.

Direct Purchase Flow

Traditional first-come-first-served ticket purchasing for regular events

1
Event Goes Live

Event is published with direct purchase enabled. Tickets become available for immediate purchase.

2
User Browses Events

Users view available events and see real-time ticket availability and pricing.

3
Select Tickets

User selects ticket type (GA/VIP) and quantity. System validates availability and user limits.

4
Secure Payment

Stripe payment form processes payment securely. Real-time validation and error handling.

5
Instant Confirmation

Payment confirmed, tickets created immediately. User receives confirmation and ticket details.

6
Digital Tickets

QR codes generated for entry. Tickets available in user dashboard for event day.

Instant Purchase

Immediate ticket confirmation with no waiting periods or uncertainty.

Real-time Updates

Live availability tracking prevents overselling and shows current stock.
