Where to start
The problem is rarely the standard: it is knowing which document holds which figure, and who to ask for it. Select what you already have and see how much of the dossier you can complete right away.
In the workspace every figure has its field, its expected unit and room to attach the document proving it. Evidence stays attached to the figure: when the bank asks where a number comes from, the answer is already there.
does not automatically extract values from files: it asks once and makes them reusable.
The document-to-figure mapping is indicative and derives from the VSME datapoint inventory: the same figure may live in different sources depending on how the company is organised.
