Online booking system, with your own rules
Appointments, rooms, equipment or events: bookings on your website, with online payment, reminders and your cancellation rules. Custom development when off-the-shelf booking tools cannot do what you need.

Beyond a certain point, booking by phone and email creates more work than it brings in: back-and-forth, reminders, no-shows, deposits tracked by hand. An online booking system moves this to your website: guests or clients choose a time, pay if needed and get reminders. There are many off-the-shelf booking tools. Lorz Kft. in Miskolc, Hungary builds custom systems where booking rules, resources or connected systems make the existing products too narrow.

Online booking systems: what to know before you decide
01What kind of booking do you need?
Different bookings follow different logic. For appointments the limiting resource is a person's or a room's time; for accommodation it is nights and room types; for rentals it is quantity and handover; for events it is seats. Clarify this first, because the calendar, pricing and cancellation rules all follow from it.
02Online payment and cancellations
Paying in advance is the best protection against no-shows, but it also affects the customer experience. Card payments always go through the payment provider's interface, so card data never runs through your system. Your cancellation terms must be stated clearly before booking, and the system has to follow them: deadlines, fees, partial refunds.
03Off-the-shelf or custom?
There are many booking tools, and for typical appointment or room bookings you can start quickly with one. Custom development pays off when resources are complex, for example staff, room and equipment at once, when pricing is custom, when booking is part of a larger system, or when data and source code should stay with your company. Booking is often part of a new website; then we plan the two together, with accessibility built in.
