I'm interested in compiling data about where money is moving -- essentially what businesses are paying other businesses and for what. This is to make a product that analyzes this data and helps users make informed decisions about the consequences of their spending. However, I have a background in mathematics, not business, so my questions are as follows:
- Is there already such a data compilation somewhere? Perhaps multiple to be aggregated?
- How much of such information is required by law to be public (if any). How much is usually available?
- If there is a decent amount available, how does one go about finding it?
I know this is a very general question. I think a unified data source could potentially be very important, but I don't even know to what extent it is possible, or where to start if so. Any information at all would be helpful. Thanks.
