Hi
The business model is simply a working description that includes the general details about the operations of a business. The components that are contained within a business model will address all functions of a business, including such factors as the expenses, revenues, operating strategies, corporate structure, and sales and marketing procedures. Generally speaking, anything that has to do with the day to day functionality of the corporation can be said to be part of the business model.

Thanks

Hello,

A business model describes the rationale of how an organization creates, delivers, and captures value]- economic, social, or other forms of value. The process of business model design is part of business strategy.
In theory and practice the term business model is used for a broad range of informal and formal descriptions to represent core aspects of a business, including purpose, offerings, strategies, infrastructure, organizational structures, trading practices, and operational processes and policies.

Thanks,
