A ticketing platform that scans correctly,
at the door, every time, not just at checkout
A ticketing platform's hardest problem is not the checkout page, it is making sure a ticket cannot be duplicated, scanned twice, or sold past capacity. We build the inventory and check-in logic with the same margin and fraud discipline we use on any store.
What it is and who needs it
A ticketing and events platform sells and validates tickets, and the part that actually determines whether an event runs smoothly is not the checkout flow, it is whether a ticket can be duplicated, scanned twice, or sold past the venue’s real capacity. This is for an event organizer, venue or platform that needs its own ticketing instead of handing a cut and the attendee relationship to a third-party ticketing giant.
What is inside
Event and ticket-tier listings with capacity limits enforced at the database level, not just checked loosely at checkout, so a sale genuinely cannot exceed the venue’s real capacity under concurrent purchase load. QR or NFC-based check-in with duplicate-scan prevention, the same ticket presented twice gets flagged, not silently let through a second time. Payment processing with real refund and transfer handling, since event ticketing generates far more refund and transfer requests than typical e-commerce and a platform without clean logic for this creates constant manual support work. An organizer dashboard showing sales, check-in rate and no-show patterns in real time, useful both on the day of the event and for planning the next one. Fraud checks on bulk-purchase and resale patterns, because scalping and bot-driven bulk buying are the two things that most damage an event’s reputation with real fans. Group and bulk-ticket purchase flows are supported where relevant, with the same capacity and fraud logic applied consistently regardless of order size.
How we build it
We build capacity and duplicate-scan logic first and test it under concurrent load, simulating the exact moment tickets go on sale and the exact moment a door opens with a line of people scanning at once, because both are the scenarios where a weak implementation fails publicly. Payment logic gets the same margin and fraud discipline we apply to any store: refund paths tested, not assumed to work; bulk-purchase patterns checked against known scalping behavior. The check-in flow is built to tolerate unreliable venue connectivity, since a check-in system that requires a perfect connection at the door is a check-in system that will fail exactly when it matters most. We carry over the same inventory-integrity and margin-guard thinking from our own digital-goods marketplace, where a verification run found zero orders processed below cost across 864 live orders. We load-test the check-in flow specifically against the concurrent-scan scenario a real event door creates, many devices scanning in a short window, since that is precisely when a weak implementation either holds up or embarrasses an organizer in front of a line of guests. Weekly demos mean your team can run a mock check-in before a single real ticket is sold. We also test the offline fallback explicitly, simulating a venue with unreliable connectivity, since a check-in system that only works with a perfect connection is one that will fail at the exact moment it matters most.
Timeline and price
| Tier | Price | What it covers |
|---|---|---|
| MVP | from $2,500 | Core flow, one platform or chain, ready to test with real users |
| Production | from $6,000 | Full feature set, handover docs, agency keeps running it with you |
| Full control (handover-ready) | from $10,000 | Same scope, built and documented for your own team to run with zero dependency on us |
Timeline: 3 to 6 weeks for an MVP; production builds typically run longer depending on integrations.
What you own at the end
The ticketing platform’s source code and its sales, capacity and check-in data, in your own database. Your own payment processor account, so funds settle directly to you, not through a shared pooled account controlled by a vendor. The organizer dashboard and its data, so running or analyzing a past event never depends on us. Check-in logs and sales history stay in your own database, useful both for a post-event report and for planning capacity on the next one.

FAQ
How much does a ticketing platform cost?
Event listings, checkout and QR check-in for a single-event or small-venue use case start at $2,500. A fuller platform with seat management, fraud checks and an organizer dashboard runs $6,000 to $10,000.
How long does it take?
3 to 4 weeks for listings, checkout and check-in. 5 to 6 weeks when seat mapping and deeper fraud and resale controls are included.
What is the stack?
Next.js or React Native for organizer and attendee apps, FastAPI or Node backend, PostgreSQL for inventory and sales, a payment processor (Stripe or a regional equivalent), and a QR/NFC check-in flow that works offline at the door if connectivity is unreliable.
Who owns the platform and the sales data?
You. Event, ticket and sales data live in your own database, and payment processing runs through your own merchant account, not a shared pooled account.
What support is included after launch?
30 days of fixes around a live event's actual check-in conditions, plus a handover document on the fraud and capacity logic. Event-day support is available as a short-term add-on.
