Is this you?
Sound familiar?
- Your books say what happened, not what to do next.
- A raise is coming and nobody owns the model.
- The board asks questions you answer a week later.
- Cash feels fine, but you can't say for how long.
- You've outgrown your bookkeeper, not your budget.
Two or more? That’s the job.
