How does AI invoice data extraction work?
AI invoice extraction reads PDFs, scans and emailed invoices, pulls out fields such as vendor, GSTIN, invoice number, line items and taxes, validates them, matches them to purchase orders and goods receipts, and queues exceptions for a person. Stack18 builds this with confidence thresholds and a full audit trail.

AI Invoice Extraction questions.
How accurate is invoice extraction?
Accuracy depends on invoice quality and variety. We measure it on your own invoices during a pilot and set confidence thresholds so uncertain fields always go to a person.
Does the AI post to accounts on its own?
Only inside rules you approve. Anything below the confidence threshold or above an amount limit goes to an approver, and every action is logged.
Can it work with Tally or our ERP?
Yes. We post to Tally or your ERP through APIs or import files and match against your PO and GRN data.
Where does our invoice data go?
We design for your cloud or approved environment with access controls, and agree data handling in writing before the pilot.
Can we try it before committing?
Yes. A fixed-price pilot on a sample of your real invoices shows accuracy and time saved before you scale.
