How much do you trust the numbers your bookkeeper is giving you?

This is something I’m really interested in as I continue growing my detailing business. I’m still building things out, so I want to make sure I’m tracking the right numbers from the beginning instead of waiting until the business gets bigger to figure it out. I’d especially like to learn which reports other owners rely on to understand their true profit, expenses, and cash flow. I know knowing the numbers is going to be a big part of scaling the business the right way
