Customer Booking Flow Click to view more information Download product brochure

The S3P modules work closely together in the booking flow to guide a customer through the “orientation” phase to select a journey with available inventory and products, proceeding into the “booking” phase where the selection is converted to a reservation that can be completed, expanded (with ancillary products and passenger information) and finally paid and confirmed in a user friendly flow. A typical S3P based booking flow in which the modules orchestrate these activities looks like this:

Orientation phase

Revenue Management

S3 RM is a software module within the S3 Passenger platform to maximize and control revenue from available market demand for rail of bus operations. In order to perform this task, S3 RM analyses historical demand and forecasts future demand for each departure, analyses the found price elasticity figures in transactional data in order to make the demand forecast price sensitive, and optimises the required booking limits based on the ongoing progress of a future departure in it’s sales cycle. With S3 RM, Revenue analysts are always fully in control by means of dashboards and real-time access to price and inventory settings.

Multi-channel distribution

  • The strength of S3P is represented by its core modules combined with sales and distribution API’s
  • All modules are managed through a single GUI back office environment (browser accessible), offering users an easy to use S3P platform.
  • Sales and distribution channel integration is facilitated with a standardised (and well-documented) set of API’s
  • Configurable prices, rules & conditions per distribution channel
  • Operators can create their own tailor-made (B2C) customer booking experience
  • S3P can be integrated with any client system based on web technology, mobile technology or other types of API driven (global) distribution channels such as ticket vending machines, station desk sales and B2B partner integrations.
