What Zera Books Extracts from Invoices
Invoice OCR quality is measured by field-level accuracy, not just whether the tool can read the PDF. A tool that extracts the invoice total but misreads line-item amounts creates more work than it saves.
Zera Books extracts structured data from every field on an invoice, with confidence scores indicating extraction certainty per field.
| Field | What's Extracted | Accuracy |
|---|---|---|
| Vendor details | Name, address, tax ID, contact info | 99.6% |
| Invoice metadata | Invoice number, date, due date, PO number | 99.6% |
| Line items | Description, quantity, unit price, subtotal per line | 99.4% |
| Tax amounts | Tax rate, tax amount, tax type (GST/HST/VAT/sales tax) | 99.5% |
| Totals | Subtotal, discount, shipping, total, amount paid, balance due | 99.6% |
| Payment terms | Net 30/60/90, early payment discount, due date | 98.9% |
