First, let’s define what a mobile hotel concierge app is, as it seems there are two readings of this currently in the industry.
A Hotel Services App
If you are looking for an app or a mobile site for guests to request services from their hotel then you will absolutely need a back end.
When the industry started building apps a few years back, it was driven by marketing. As such, little attention was given to the back-office operations required to actually execute these requests. As we have observed in other industries, mobile services are only a step change improvement for consumers when the consumer has access and transparency to the status of the request. When you request an Uber, you see when it is at your doorstep. Likewise, when you request food via Seamless, you know exactly how long it will take for your food to be delivered. This level of context requires the back-office staff, the actual service “deliverers” to be on the same platform. That means consideration of back-office operations is actually far more important than the mobile app access point (the consumer-facing front-end).
