1 · The problem
An operations team handled 40-50 invoices a week by hand.
2 · Agent setup
A 23-step n8n workflow reads invoice PDFs from email, checks items against an inventory sheet, creates a purchase order and notifies the team.
3 · Result
About 90% now process automatically, saving roughly 8-10 hours a week; it took 3 days to build.
4 · Copy-paste prompt
Check this invoice against inventory.csv: do the items exist, are quantities and unit prices within 10% of the last order? Output 'approve' or 'review' with reasons.
