One PDF In, Fifteen Structured Fields Out.
When invoices arrive outside email — via postal mail, messaging apps, or vendor portals — drag and drop the PDF into Inbox Ledger. SHA-256 deduplication prevents double-processing, batch uploads run in parallel, and AI extracts vendor, amounts, dates, tax, currency, and every line item. No template setup, no OCR training, no manual mapping.
Key PDF Invoice Extractor Capabilities
Built-in functionality that eliminates repetitive document tasks
Drag, Drop, or Batch Upload
Drag one or many PDFs into the dashboard, or click to browse. Multiple files are processed in parallel — upload an entire stack of invoices in a single session.
Zero-Template AI Extraction
No rules to configure, no layouts to map. The AI model understands invoice structure from any vendor, any format, any country — out of the box.
Scanned & Photographed PDFs
Paper invoices scanned at the office or photographed with a phone are handled through a multi-pass OCR layer — even low-resolution images produce reliable output.
Per-Line-Item Extraction (97.5%)
Every line item is captured: description, quantity, unit price, tax rate, and subtotal. Not limited to header fields — the full document depth is extracted.
Multi-Language & Multi-Currency Ready
Upload invoices in any language or currency. The same extraction engine handles Latin, CJK, Arabic, and Cyrillic scripts with automatic detection — no manual selection required.
SHA-256 Duplicate Guard
Each upload is hashed with SHA-256. If an identical file has already been processed for your organization, you are notified immediately and no credit is consumed.
Supported PDF Document Types
AI identifies and extracts data from every supported format
Native Digital Invoices
Text-based PDFs generated by accounting software, SaaS billing engines, and e-commerce platforms — the highest accuracy tier with per-field confidence scoring.
Scanned Paper Invoices
Paper invoices scanned at the office or captured via mobile camera. The multi-pass OCR layer handles varied resolutions and scan qualities.
Multi-Page Documents
Complex invoices spanning two or more pages — including detailed line-item tables — are processed as a single document with full context preserved.
Credit Notes & Refund Memos
Vendor-issued credits and refund documents are automatically tagged and extracted with correctly signed negative amounts.
Purchase Orders
PO documents are extracted with order number, vendor, and line items — useful for three-way matching against invoices and goods receipts.
Multi-Currency Invoices
Invoices in any currency are processed with automatic detection. Exchange rate conversion to your org's base currency is available via the Multi-Currency Converter.
How It Works
From connection to first extracted invoice in under five minutes
Drag and Drop PDFs
Drag one or more PDF invoices into the upload area — or click to browse your local file system. Batch uploads are processed in parallel.
Deduplication & Credit Check
Inbox Ledger computes a SHA-256 hash of each file. Duplicates are flagged instantly. Available credits are verified before extraction begins.
AI Extraction with Confidence Scoring
The engine extracts vendor, amounts, dates, tax, currency, and line items from each document — returning structured JSON with per-field confidence scores for quick review.
Review, Correct, and Export
Inspect the structured output in your dashboard. Edit any field if needed, apply tags, then push to QuickBooks, Xero, Sheets, Drive, or OneDrive.
Who Benefits Most

Office Managers
Invoices arriving by postal mail, WhatsApp, or courier can be scanned to PDF and uploaded — filling the gap that email scanning cannot cover.
Bookkeeping & AP Teams
Batch-upload a stack of paper invoices after scanning them to PDF. The parallel processing engine handles dozens of documents in a single session.
Mobile-First Professionals
Photograph a paper invoice, save it as PDF on your phone, and upload it directly. Extraction begins immediately — no desktop required.

Frequently Asked Questions
All standard formats: native digital PDFs (text-based), scanned image PDFs, and mixed-content documents. Password-protected PDFs must be unlocked before upload.
Yes. The upload interface accepts multi-file selection and drag-and-drop of multiple PDFs. Each file is processed independently and in parallel.
Each upload generates a SHA-256 hash of the file content. If an identical file already exists in your organization, you are notified immediately and no credit is consumed.
No. Unlike rule-based OCR tools, Inbox Ledger uses large language models that understand invoice structure without pre-configured templates. Every vendor format is handled on the first upload.
Single-page invoices are processed quickly, with multi-page documents taking slightly longer. Processing runs in the background — you can continue working while extraction completes.
No. Manual uploads are treated as intentional — they bypass the AI pre-classifier and enter the extraction pipeline directly. Each uploaded PDF consumes one processing credit.
PDFs up to 20 MB are accepted. For scanned invoices, keeping files under 10 MB improves processing speed. Multi-page scans perform best with compressed PDF output.
The invoice extractor accepts PDF only. For bank statements, additional formats — CSV, XLSX, OFX, QFX, MT940, and BAI2 — are supported through the Bank Statement tool.
