A Worked Example
Defensibility, by arithmetic.
An indirect rate is only as defensible as the pool that produced it. The exhibit at right shows a Q3 actual rate calculation as DCAA Companion presents it: pool, base, ratio — line-traceable to the GL accounts on each side of the equation.
No re-typed numbers. No "ask the controller for the spreadsheet." Hover any pool and the underlying transactions appear; click a transaction and the source document follows.
DCAA asks: "Can we trace every billed dollar to an allowable source, using your normal books and records?" If the answer is yes, audits are procedural — not adversarial.
