What happens when a hotel guest needs help and a simple message isn't enough?

A guest may need to communicate with the hotel during check-in or check-out.

Sometimes a text message is enough.

Sometimes the conversation needs to happen right now.

And sometimes, a voice call is simply easier.

For GuestWindow, the challenge was not just to build another hotel management interface. The project required a platform that could support hotel and guest history, real-time chatting, voice communication, marketing, staff management, and third-party integrations.

Sparkle Web built GuestWindow using Angular, .NET Core, Web API, MSSQL, Entity Framework Core, Azure Blob Storage, and other Azure services, with Twilio for chat and audio calling and SignalR for live chatting.

The Business Challenge

Hotel communication can involve many moving parts.

GuestWindow was designed to maintain hotel and guest history with Twilio chat for check-in and check-out. The platform also needed communication capabilities between hotel users and guests.

But communication was only one part of the project.

The platform also needed:

• Admin and hotel panels
• Live chat
• Voice calling
• SMS and email marketing
• Staff management
• Third-party API integration
• Cloud storage
• Performance improvements

The client also identified performance improvement as a major challenge.

This meant the solution had to bring multiple business requirements together instead of solving only one isolated problem.

Building GuestWindow From the Ground Up

Sparkle Web created the Admin and Hotel panels from scratch using .NET Core Web API and Angular.

The documented technology stack included:

This architecture provided the foundation for the different modules and communication requirements of the platform.

Why SignalR Was Used for Live Chat

One of the key technical requirements was live chatting.

Sparkle Web implemented SignalR for live chat in GuestWindow.

For a hotel communication platform, real-time interaction can make a major difference to the user experience.

Instead of relying on users to repeatedly refresh a page, a real-time communication layer allows the application to handle live interactions between connected users.

In GuestWindow, SignalR became an important part of the communication experience between hotel users and guests.

Twilio Added Chat and Voice Communication

GuestWindow also required more than text-based communication.

Sparkle Web implemented Twilio for live chat and audio calling, including Twilio Chat and Voice Call APIs for communication between hotel users and guests.

This created two important communication options:

Live Chat + Audio Calling

That combination makes sense for hospitality workflows where a guest may need to communicate quickly with hotel staff.

Instead of forcing every interaction into one communication channel, the platform supported different ways to connect.

More Than a Communication Platform

GuestWindow was not limited to chat and voice.

The documented modules also included:

SMS & Email Marketing

The platform included SMS and email marketing modules for sending messages and emails for marketing purposes.

Staff Management

Staff management was included as another part of the platform.

Third-Party API Integration

The project included third-party API integration to connect external services with the portal.

Azure Blob Storage

Azure Blob Storage was also part of the documented implementation.

This is what makes GuestWindow an interesting custom software case study.

It wasn't simply “a chat application.”

It brought multiple business functions into one platform.

Performance Was a Key Part of the Project

Adding features is only one part of building business software.

The application also needs to perform well.

The GuestWindow project specifically identifies performance improvement as one of the client's main challenges.

For a platform combining communication, hotel operations, marketing modules, integrations and data management, performance needs to be considered as part of the overall application development process.

This is particularly important when building applications where users expect responsive interactions.

The Bigger Lesson From GuestWindow

GuestWindow shows why custom software development often starts with the business workflow, not with a technology list.

The requirement wasn't simply:

“We need a chat feature.”

The broader requirement was to support hotel and guest communication, history, voice calls, marketing, staff management, integrations and cloud storage within the platform.

The technology was then used to support those requirements.

That's an important difference between buying a generic application and building software around a specific business process.

Where Similar Real-Time Applications Can Help

The GuestWindow approach can be relevant to businesses that need real-time communication as part of a larger workflow.

Examples include:

• Hospitality platforms
• Customer support systems
• Healthcare communication
• Logistics applications
• Booking platforms
• Service management software
• Internal business applications
• Workflow automation platforms

The exact architecture should always depend on the business requirements, users, integrations and communication needs.

Final Takeaway

GuestWindow is a strong example of how real-time communication can become part of a complete business application.

Sparkle Web combined .NET Core, Angular, SignalR, Twilio, MSSQL, Entity Framework Core and Azure services to build a platform around hotel and guest communication requirements.

The lesson is simple:

Don't just add another communication tool. Build communication into the workflow.

If your business needs real-time chat, voice communication, third-party integrations or a custom workflow platform, Sparkle Web can help you design and develop a solution around your actual requirements.
