your money, lost.
Your budgets live in tools that were never built for events — templates that don't fit, formulas that break. Keeping every number current takes time you don't have, so your real margin is often anyone's guess.
And your client numbers are permanent. Once a version goes out, you stand by it — you can't walk back a mistake three versions later. So quiet errors and unvetted costs compound: your margins erode, your cash tightens, and you lose money on strong work.
Everything stems from the health of your budget.
