Custom Hotel Booking Platform Solutions

You find the perfect room on Airbnb... You click “Book Now.” Payment done. Then comes that email: "Sorry, the room is already booked." 😤 The frustration is real. 💡 So how do platforms like Airbnb or Booking.com solve this? - Rooms listed by hosts appear instantly to customers — no page reloads needed. - If one customer starts payment, the room disappears from others' search results. - If the payment fails or times out, the room is released back into availability. All this happens in real-time, without breaking the user experience. ✅ The answer: Event-Driven Architecture Here’s how i tried to recreate in my SAP-based design: 🔹 Customer searches for rooms → Search Service checks real-time availability via SAP Event Mesh 🔹 Customer picks a room → Booking Service reserves it in Redis (temporary hold for 10 minutes) 🔹 Booking Service publishes an event → Room marked as on-hold 🔹 Hotel Service updates availability → Everyone else sees 1 less room 🔹 Payment Service completes transaction → - Success → Room confirmed in S/4HANA Cloud - Fail/Timeout → Room released, event broadcasted 🎯 Why this system design: ✅ Prevents double bookings ✅ Keeps availability always accurate ✅ Uses Redis for smart, temporary caching ✅ Integrates with S/4HANA Cloud for backend ops (HR, finance, procurement) ✅ SAP Document Management can store images, invoices, and more This is a real-world case for event-driven microservices done right — blending customer experience with enterprise robustness. #SAPBTP #EventDrivenArchitecture #Microservices #Redis #S4HANA #SAPCAP #SAPEventMesh #DesignThinking #CustomerExperience

Some things take years to build, and when released they look so simple and logical that it is hard to truly understand the complexity and possibilities behind it at first glance. This is one of those product releases. I wanted to talk you through some of the amazing possibilities for your hotel business. This new booking engine is enabled only because we did the hard thing first in the PMS, to build a flexible architecture that supports the true complexity of your business: ALL TYPES OF SPACES You can load any type of space. Hotels are much more than just bedrooms, we should also offer co-working, parking, bicycle rental, karaoke rooms, meeting rooms... you name it. The more you offer, the more you sell. FLEXIBLE TIME UNITS Each of these services has a different unit of time. For example a bike you may only rent for a couple of hours, where a co-working desk would be a day rental and a bedroom per night. LIMITED INVENTORY All of the services have an inventory, because they all have limited availability. If you only have 10 bikes, the system will know this, and stop selling this service when sold out. YIELD EVERYTHING Traditionally in hotels you can only yield the prices of bedrooms, but parking is always the same price, why? Now it is possible to make every service you sell, yield-able, and through the restrictions you can even put limitations if needed. Just have a look at this short demo of just 2 simple use-cases to get a sense of the possibilities.
