‍

Integrations with Third-Party Services or External Systems

One of the distinct advantages of Microsoft Teams lies in its extensive integrations with other productivity tools and third-party applications. Any business messaging platform looking to compete must include these versatile integrations, as they can greatly extend the platform's utility.

‍

Audio/Video Calling Integration

To support high-quality audio and video calls, your app would need integration with third-party services such as Twilio or Agora, which provide APIs for embedding video and voice functionalities into the app. These external services guarantee near-zero latency during live calls, but they come with licensing fees, increasing the app's ongoing operational costs.

‍

Calendar and Project Management Tools

Many Teams users rely on Microsoft Office 365, Google Workspace, and services like Asana to manage projects. Your app must successfully integrate these third-party systems for seamless transitions between communications, scheduling, and task assignments. Building robust APIs for these integrations increases both cost and required development time, due to the rigorous testing and compliance checks needed to sync data in real-time between multiple providers.

Ensuring secure handling of user payments while maintaining PCI-DSS compliance introduces another development layer.

‍

The deeper the level of third-party integrations, the longer your team will spend ensuring seamless operation between systems—raising both the development timeline and the overall app development cost.

‍

Database & Back-End Infrastructure

The back-end infrastructure for an app like Microsoft Teams needs to be extremely reliable, scalable, and able to process a vast volume of real-time data without delays. Given the collaborative nature of the app, the platform needs to support everything from real-time communication to file storage and complex database queries for users across multiple time zones.

‍

Cloud Infrastructure

The app’s infrastructure will require top-tier cloud services to handle real-time data processing, document sharing, and video conferencing. Leading providers like Amazon Web Services (AWS), Google Cloud, or Microsoft Azure enable the efficient handling of tasks like data storage, user authentication, and file synchronization.

‍

The app development cost might fluctuate based on whether you opt for a shared cloud environment or invest in a dedicated infrastructure capable of delivering enterprise-level security and uptime. For large-scale corporate products, the latter is often necessary, especially when dealing with sectors like finance, healthcare, or government.
