The finance chief of spend management company PEX described building a second, AI-maintained copy of the company's accounting ledger to run alongside the real books as a way to catch errors, with a target of 80% to 90% completion by the end of the year. His team already uses agents built on Anthropic's Claude to chase missing expense receipts, answer policy questions in Slack and move data between the card, HR, banking and accounting systems. It is one company's account of work in progress rather than a finished or externally verified system.
What changed
Finance staff chased missing receipts and expense-policy exceptions by hand, and data moved between card, HR, bank and accounting systems manually.
