Model can be stored online or offline completely at your control. 

Any data can be automatically linked will the model, improving processing efficiency and overall consistency of the model.

Different data sources come in different layouts, formats, style. The input section of the model will convert them into a model friendly format and import relevant information to the final version.

Database design, 'smart' links, back and forth checks, automated calculations, reconciliations are just a few features that help to process data systematically, without omissions and errors.

Spreadsheet approach allows to modify, extend or amend a model, its sections or data handling processes, at will, without tedious redesigning efforts.

Model approach is balanced between two extreme scenarios, namely (i) overwhelming a reader with too many numbers which make calculation unclear and (ii) creating a backbox, one step final result.
