Does anyone know of anything in the spirit of something like plain text accounting (https://plaintextaccounting.org/) but adapted to integrate the complexities of a wealthy family? I intend to implement something myself, but was interested in knowing whether there was anything like this out there, or to hear from someone with experience with this problem.<p>The point would be to design something that substitutes for Addepar but with a sensibly organized sqlite db and csvs as "first class" sources of truth (and scripts to handle a variety of common functionality).<p>So it is really an exercise in understanding the correct architecture of various hierarchies, relationships, and categories in the context of a wealthy family.<p>All the major software out there just does not seem very good, appear to have a principled handle on the fundamental and primitive relationships and operations that describe a family's financial affairs (everything done on an <i>ad hoc</i> basis). And because of this, entail complete data/platform lock-in.
