We could expand this application with many server-side additions, such as the direct download of information from the bank account, or the synchronization of the data with the family (in this case, we need an authentication system).

To keep the project easy and make it doable within one chapter, we have to decide which features will be mandatory for our Minimum Viable Product (MVP).

MVP is defined as the product with only those core features that allow the product to be deployed, and no more.

• The application is for a single user
• A user can create many accounts
• A user puts information about each transaction by hand
