The Real Problem
Your close date, your cash position and your reporting all depend on a team that is already stretched. Hiring locally takes months and costs a premium, and the work does not wait.
Staff burnout, missed closes, and work you turn away because the team is already full.
Controllers spending most of their week reviewing transactions instead of advising.
Months to hire, months to train, then they leave for a small raise elsewhere.
Output quality swings between people, entities and months. Nothing is repeatable.
