And how do you know if you have been breached if you (negligently, in my opinion) have no audit logging, multiple principals sharing the same account, and no anomaly tracking? Does a breach only happen if the attacker brags openly about it?

The difference with accounting is that, relatively speaking and certainly within this context, few businesses are cash businesses. Your bank is keeping at least a basic audit log of money coming in and out of the corporate bank account. Your payment processor is keeping at least a basic audit log of who paid you and how much. You won't make your auditors happy if they're the only documents you have, but they're at least something to be handed over in an audit that pretty much every software business will have. Cybersecurity? By default, nothing is collected.
