Built for the on-sale spike
Inventory holds, queueing and concurrency control so a popular on-sale does not double-sell or fall over.
We build custom event ticketing platforms: seat maps, inventory holds, high-concurrency on-sales, QR check-in and promoter payouts, built to hold up on launch.
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.
Inventory holds, queueing and concurrency control so a popular on-sale does not double-sell or fall over.
Reserved seating with interactive maps, general-admission capacity and tiered ticket types in the same engine.
Checkout and payment flows that never charge twice or sell a seat that was not paid for, even under retry storms.
Issued QR or barcode tickets and a fast door-scanning flow that works offline and syncs when it reconnects.
Refunds, exchanges and ticket transfers handled cleanly, with the ledger kept straight throughout.
Real-time sales, allocations and reporting for organisers, with payouts reconciled to what actually sold.

“They have a deeper technical knowledge than any web designer I've met to date.”
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.
Yes. Interactive seat maps for reserved seating and capacity-based general admission run in the same engine, with tiered ticket types across both.
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.
