People doing this work are accountable for every dollar. A program officer at HHS can ask, eighteen months from now, why a $312 charge hit the Title III fund instead of general operations, and a nonprofit's finance team has to produce a paper trail that answers it. Every transaction is potentially a question from the government.
It is being done on tools that were not built for it. QuickBooks does not know what an award is. Excel does not know what an allowable cost is. The institutional knowledge that holds this together lives in one person's head, and when that person leaves, the organization loses years.
Fiscle exists to close that gap — not by replacing the general ledger, but by living on top of it, doing the work that sits between the books and the funder.
