How We Built an Event Ticketing & Registration Platform for a Lagos Events Company

A Lagos events company was managing ticket sales through bank transfers, manual name lists, and paper tickets at the door. They organised over 200 events per year—concerts, conferences, festivals, and private parties—and every event was a logistical nightmare of reconciling payments, managing long queues at check-in, and dealing with fraudulent tickets. They needed a platform that could handle the entire ticketing lifecycle from sale to entry.

We built an end-to-end event ticketing and registration platform in 10 weeks. The platform handles ticket sales via Paystack, generates unique QR codes for each ticket, provides a mobile check-in app for venue staff, and gives organisers a real-time sales and attendance dashboard. In the first year, the platform sold over 50,000 tickets across 200+ events with 99% check-in accuracy.

The Challenge

Manual Ticketing Was Unsustainable at Scale

The company's existing process was entirely manual. Customers would request tickets via Instagram or WhatsApp, make a bank transfer, send a payment confirmation, and have their name added to a Google Sheet. On event day, venue staff would check attendees against a printed list. This process was error-prone, time-consuming, and vulnerable to fraud. People could claim to have paid without actually doing so, and there was no reliable way to verify attendance numbers in real time.

For paid events, reconciling bank transfers against ticket purchases was a significant burden. The finance team spent days after each event matching transaction references to attendee names. Refunds were a manual process that often took weeks to complete.

Check-in Chaos at Large Events

Events with over 1,000 attendees often experienced long queues at the entrance as staff manually checked names against printed lists. There was no way to prevent duplicate entries or track how many people had arrived. The company had no data on show rates, peak arrival times, or attendee demographics, making it difficult to plan future events effectively.

Our Solution

Digital Ticketing with QR Code Validation

We built a ticketing platform where event organisers can create events, set ticket types and pricing, and launch sales within minutes. Ticket purchases are processed through Paystack, and each ticket generates a unique encrypted QR code. Attendees receive their QR tickets via email and SMS immediately after purchase, with the option to add them to Apple Wallet or Google Pay.

The platform supports multiple ticket tiers (early bird, regular, VIP, etc.), discount codes, group purchases, and free ticket registration for events that do not require payment. Organisers can set ticket limits, sales windows, and automatic waitlists when events sell out.

Mobile Check-In App

We developed a lightweight React Native check-in app that runs on any Android or iOS device. Venue staff scan QR codes using the device camera, and the app instantly validates the ticket, marks the attendee as checked in, and prevents duplicate scanning. The app works offline, queuing check-ins locally and syncing when connectivity is restored, which is critical for venues with poor network coverage.

The real-time dashboard shows organisers exactly how many people have arrived, peak check-in times, and the remaining capacity. This data helps with crowd management, resource allocation, and post-event reporting.

Attendee Management and Analytics

Organisers get a comprehensive attendee management dashboard where they can view guest lists, send bulk notifications via email or SMS, export attendance data, and generate post-event reports. The analytics module tracks sales trends, show rates by ticket type, revenue per event, and customer acquisition channels.

The Results

The platform launched in 10 weeks and was immediately adopted for the company's next major event—a 5,000-attendee music festival. The QR check-in process moved 5,000 people through the gates in under 90 minutes, compared to the 3+ hours it would have taken with manual checking. Fraudulent tickets were eliminated entirely because each QR code was cryptographically signed and could only be scanned once.

Over the first year, the platform processed 50,000+ ticket sales across 200+ events. The company saved an estimated ₦12 million in administrative costs, eliminated ticket fraud, and gained valuable data insights that helped them optimise pricing and marketing for future events. The check-in app achieved 99% accuracy, with the 1% error rate being entirely due to attendees presenting screenshots of expired tickets.

Key Takeaways

• QR code ticketing eliminates fraud. Unique encrypted codes that can only be scanned once completely solved the fake ticket problem.
• Offline check-in is essential for Nigerian venues. Network coverage at event venues is unreliable. The offline-first architecture of the check-in app was critical.
• Automated payment reconciliation saves days of work. Paystack integration meant every payment was automatically matched to a ticket purchase.
• Real-time attendance data improves event management. Knowing exactly how many people are inside helps with security, catering, and compliance with venue capacity limits.
