Finance teams next to a lakehouse all know the queue. The data is right there, every order, every transaction, every usage record, but getting an answer out of it means filing a ticket and waiting for someone on the data team to find time between their own priorities. So the monthly check against the books slips, the export from last quarter gets reused, and the question "are we invoicing everything" gets answered with a shrug and a sample.
Nance gives finance a direct line. It queries Databricks through a service principal you control, checks operational datasets against the administration, verifies revenue completeness against real order and usage data, and answers ad hoc questions from the tables you exposed. The data team keeps owning the platform; finance stops borrowing their calendar to use it.
