The finance work that slows a company down is rarely difficult. It is just badly placed. The payment run waits in a mailbox until someone surfaces from back-to-back meetings. The receipt stays in a coat pocket because filing it means opening a laptop. The question about an invoice gets forwarded three times before it finds the person who knows.
Putting Nance in Teams moves that work to where your team already is. An approval arrives with the context to judge it and a button to tap. A receipt is handled from the restaurant doorway. A question about the books gets an answer in the time it takes to type it, with the entries linked so you can check her working.
What that buys you is not a faster tool, it is a finance function that stops depending on someone being at their desk. Approvals happen the day they arrive instead of the week they arrive. Documents reach the books on the day they exist. Nobody chases anybody for status.
The work itself happens in your accounting system, under rules you set, with every action logged and attributed. Payment runs show where the line sits: Nance prepares the batch and hands it to you, and you release it at your own bank. She never holds your banking credentials and never moves money herself.
