Today's Agent Skill: Invoice Data Extractor
What It Does
Manual invoice entry is tedious and error-prone — one transposed digit can cascade into hours of reconciliation. This skill pulls structured data from invoices in any format and outputs clean, bookkeeping-ready records.
How It Works
The Invoice Data Extractor accepts PDF, image, or text invoices and extracts vendor name, invoice number, line items, totals, tax, and due date. It normalizes the output into a consistent schema that drops directly into QuickBooks, Xero, or a simple spreadsheet — no reformatting required.
How to Deploy It
Point this skill at your invoices folder or email attachment stream for semi-autonomous processing. For full autonomy, pair it with an email filter that routes vendor invoices to a dedicated folder, then run the extractor on a schedule that populates your accounting queue.
