Your team wrote it all down once. The spend policy, the approval limits, who owns which supplier, how month-end is supposed to go. It lives in Notion, it was accurate the week it was written, and nobody making finance decisions actually opens it. So the policy says one thing, practice does another, and the wiki slowly turns into a museum of how the company used to work.
Nance closes that gap from both sides. It reads your Notion pages as working context, so the rules and budgets you documented are applied when invoices, expenses and payment decisions come through. And it writes back: wiki pages updated when reality changes, findings and open items logged in the databases your team already checks. The finance work itself happens in your accounting system; Notion is where Nance learns how you want it done, and shows what it found.
