Every step of the ticketing journey
A ticketing platform spends most of its life quiet and then has to survive a few minutes where every customer arrives at the same second. The hard engineering is all in that window: holding inventory correctly under contention, not double-selling a seat, and staying up while the on-sale traffic spikes.
Seat maps and general admission
Reserved seating with interactive maps, general-admission capacity and tiered ticket types in the same engine.
Idempotent payment flows
Checkout and payment flows that never charge twice or sell a seat that was not paid for, even under retry storms.
QR tickets and check-in
Issued QR or barcode tickets and a fast door-scanning flow that works offline and syncs when it reconnects.
Refunds and transfers
Refunds, exchanges and ticket transfers handled cleanly, with the ledger kept straight throughout.
Promoter dashboards and payouts
Real-time sales, allocations and reporting for organisers, with payouts reconciled to what actually sold.

Frequently asked questions
01Can it handle a high-demand on-sale?+
That is the case we design for. Inventory holds, a queue in front of checkout and concurrency control stop double-selling and keep the platform up when everyone arrives at once.
02Do you support reserved seating and general admission?+
Yes. Interactive seat maps for reserved seating and capacity-based general admission run in the same engine, with tiered ticket types across both.
03How does check-in work at the door?+
Tickets are issued as scannable QR or barcodes, and the door app validates them quickly, works offline if the venue connection drops, and syncs once it is back.
