In this project, the client asked us to create and develop a web and mobile application to manage and track expenses and expenditures within the company and facilitate sound financial decision-making.

The Moola Pay application was created to address several challenges, the most important of which are:

• Clarity and Visibility: Lack of live monitoring and clear visibility of the company’s expenses.
• Organizing expense management: The process of managing expenses on paper is inefficient and takes a long time.
• Automation and integration: Lack of automation and integration with other systems
• Information security: Lack of data security and non-compliance with regulations and legislation.

Proof of Concept :

It is an important stage in the software development process where a prototype or experiment is created to demonstrate the ability to achieve a specific function or set of functions in the final product. For a Moola app, a proof of concept may include: Develop a prototype: Create a prototype version of the app that contains the basic functionality for expense management. Validate the idea: Test the prototype to ensure that the app idea is feasible and can be successfully developed. Gather feedback: Use the prototype to gather feedback from potential users and identify requirements and necessary improvements. Technology Evaluation: Ensure that the technologies used in the application support the required functionality and are stable and secure.

Analysis of how it works within the application:

This analysis was based on the client's requirements and knowledge of how expenses and expenditures are managed manually and converted into a secure digital form, as follows: 1 The employee makes an expense and records the data related to this expense in a digital and secure manner, and this expense is in a state of being approved. 2 The management reviews this expense and has the decision to approve or reject it. 3 In case of acceptance, the expense amount will be sent to the employee’s account by sending it to the employee’s wallet or bank card. 4 In case of rejection, the expense value will not be sent to the employee and the employee will bear the value of this expense. All these processes and steps are properly documented using notifications or emails exchanged between employees and various departments.

Web and mobile based solution:

First, the web: We used the .NET language for back-end programming and development, ReactJS for front-end programming and development, MySQL for databases to store data within the application. These technologies are suitable for large systems that require precise handling of large amounts of data. Second, mobile: We used the Flutter programming language for mobile app development. It is easy to use and highly professional in creating apps that run on both Apple and Android platforms.

Compatibility:

We have made the application compatible with web browsers such as Google Chrome, Mozilla Firefox, and Microsoft Edge, and its front-end runs on Single Page Application. The application can also be opened on a mobile phone as we are keen in our work to ensure that the application is compatible with use on all screens, small and large, by making the application compatible with all sizes. This is in addition to the mobile application that is compatible with Apple and Google software systems smoothly.
