AP Automation · 6 min read

PDF invoices, receipts, bills. Out comes a clean Excel sheet.

Finance and accounts-payable teams shouldn't be transcribing invoice line items. Aarkiv's invoice-to-Excel converter reads PDFs (born-digital and scanned), images, and bulk ZIPs, extracts the exact fields you ask for, and exports a spreadsheet. No per-vendor templates. No manual entry. Custom field schemas, bulk processing, AP-ready output.

Why finance teams keep losing this game

Accounts payable still runs on a copy-paste loop. Vendor sends a PDF. AP analyst opens it. Types vendor, invoice number, date, amount, tax, currency, PO, line items into NetSuite or QuickBooks. Saves it. Files it. Repeats. Five hundred times a month. Mid-market companies pay full-time salaries to people doing this. Enterprise companies build entire AP automation programs around it.

Generic OCR tools (Adobe, Tesseract, ABBYY) get you the text but not the structure. Template-based extractors work until vendor 47 sends an invoice in a new layout. Modern invoice OCR + LLM extraction is template-free: you describe what you want, the system reads each invoice page-by-page and returns structured JSON.

How Aarkiv's invoice extractor works

  1. Drop in your files. One PDF, fifty PDFs, or a ZIP with all of them. We accept PDF, PNG, JPG, WEBP, and zipped batches.
  2. Define the fields. Vendor, invoice_number, invoice_date, total, currency by default. Add tax, PO number, billing_address, line_items, anything else. Up to twelve fields per job.
  3. Hit Extract. Aarkiv validates every file, safely unpacks any ZIP, sniffs magic bytes (no executables get in), reads each page with a vision pipeline, and pulls the fields you asked for.
  4. Download Excel. One row per invoice, one column per field. Plus the original filename so the audit trail is clean.

Formats and edge cases we handle

Built secure by default

Invoice extraction touches every vendor relationship and a lot of regulated data. Aarkiv treats uploads as hostile until proven otherwise: ZIPs are walked entry-by-entry with symlink, path-traversal, encrypted-entry, and zip-bomb defenses; every saved file is magic-byte sniffed (no .pdf containing executables); files land outside the web root with 0600 permissions owned by a non-privileged user. Hard cap of ten pages per turn keeps abuse small and predictable.

Aarkiv vs. classic invoice OCR tools

vs ABBYY

No per-template setup

Aarkiv reads layout from the page itself. New vendors work on day one, no template authoring, no field mapping rules.

vs Adobe OCR

Structured output, not text dumps

Adobe gives you a searchable PDF. Aarkiv gives you the fields, in Excel, ready for your ERP.

vs Tesseract

Vision + reasoning, not just OCR

Reading the characters is the easy half. Knowing what is the invoice number vs. the PO number vs. the customer ref is the hard half.
