Xero makes the books pleasant to look at. It does not make the work behind them disappear. Bills still wait in inboxes, the bank feed still fills up faster than anyone reconciles it, and a handful of lines without paperwork can stall a period for days.
Nance takes over that layer. It connects to your Xero organisation through the official API and works the way a careful finance colleague would: it reads what comes in, books what it is sure about, prepares what it is not, and leaves an audit trail behind every step. You set the rules once. Nance applies them every day.
