Why it matters
Money tasks are tedious but high-stakes, which is exactly where a careful agent helps: it does the checking and paperwork while a person keeps the final say. It is one of 65 sightings filed under Finance on Agent Sightings (number 25 by interest), and one of 36 involving n8n.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into n8n or any similar agent and adjust the details to your situation.
For each attached invoice, extract number, issue date, due date, vendor, amount, currency. Rename the file as MM-YYYY_Invoice-<number> and add a row to the ledger.
Tip: Keep the agent in 'propose, don't pay' mode: let it gather numbers and draft messages, and approve any payment or account change yourself.
