Timerise builds custom booking software, and nothing else. Our clients are clinics, public offices, brands that run events, fitness studios, rental companies and coworking spaces. Each of them has outgrown a ready-made booking tool, or never fitted one. We write a system for the way they take bookings, and hand over the source code, the data and the documentation at the end. They pay once. There is no licence and no fee per booking.
Booking is a narrow field with many traps: availability rules, time zones, calendar sync, deposits and refunds, reminders, on-site kiosks and screens, invoices, and links to CRM or ERP systems. We learned them by running our own booking engine in production from 2021. Today each of those parts is a tested module, published as an open Agent Skill that anyone can read, and we build new systems from them on the client's own stack.
You start with a short brief. In 48 hours you see a clickable prototype and get a fixed quote, before you sign anything. The build takes 2 to 3 weeks, and most projects go live 6 to 8 weeks after kickoff. A project usually costs $15,000 to $50,000. That price includes moving your data from the current tool, deployment to your cloud or ours, and three years of support.
Past work: visit booking for the Consulate General of Ukraine (more than 50,000 visits), event and workshop booking for Valmont, session booking for the therapy marketplace Risify, and registration for Startup Festival Wrocław.
You talk to the people who write the code. Piotr Kozak leads product and UX, Mateusz Sowa leads backend and infrastructure.
