A platform for planning concert tours: a venue catalogue, a map, a cost and attendance calculator and event publishing, plus QR-code tickets, sales and settlements.
Live platform: letsplayagig.com for the international market and koncertuj.com in Poland, on a shared database.
Our own Localize.pl project, not client work.
A band planning a tour usually works it out in a spreadsheet: fuel, accommodation, crew, the venue fee or a share of ticket sales. Every change of city or expected attendance means recalculating everything.
Let’s Play a Gig brings venues, the route and the economics of each gig into one place, and then handles the event itself.
The calculator covers crew, travel and accommodation costs and five deal models with venues. The band compares attendance scenarios before committing to a tour. It is a cost and profitability simulator: the band chooses the order of gigs, and distances are estimated.
Choosing venues and planning the next gigs on a map, based on a shared venue catalogue.
Tickets are generated as PDFs. At the door the code is scanned with a phone camera, and if the camera fails it can be typed in by hand.
Ticket use is recorded in the database in a single, indivisible operation. Two simultaneous scans of the same code will not let two people in, because the database decides, not the scanner screen.
In the Polish version, payments through Autopay and invoices in KSeF (described separately as the settlement module), plus notification queues.
| Technology | Role |
|---|---|
| Next.js, React, TypeScript | Application for bands and organisers |
| PostgreSQL, Drizzle | Shared data on venues, tours and events |
| Leaflet | Venue map and tour planning |
| pdf-lib, qrcode, jsQR | PDF tickets and a phone-based code scanner |
| Autopay, KSeF | Payments and invoicing in the Polish version |
The platform is live in two market versions. The planner calculates costs and profitability for the options the band chooses; it does not plan the route automatically.
