Structured Invoice Data in Seconds, Not Hours
Feed Inbox Ledger any invoice — a native PDF, a phone photo, or a scanned document — and receive structured data with 99.5%+ field-level accuracy. The engine handles 50+ languages, recognizes 170+ currencies, and completes extraction in under 30 seconds per document.
Why Choose Inbox Ledger for AI Processing
Core advantages that set Inbox Ledger apart
Zero-Config Layout Understanding
Large language models parse invoice structure on the fly. There are no templates to build, no zones to draw, and no vendor-specific configuration.
Multi-Pass OCR for Physical Documents
Scanned PDFs, phone photographs, and degraded copies go through a multi-pass OCR pipeline optimized for real-world document quality.
Broad Language Coverage
Process invoices in English, German, Spanish, Japanese, Arabic, Chinese, and 45+ additional languages. Mixed-language documents — such as English headers with Japanese line items — are handled natively.
Automatic Currency Detection
The engine identifies the invoice currency and converts amounts to your organization default using daily rates from Open Exchange Rates. Both original and converted values are stored.
Full Line-Item Granularity
Extraction goes beyond header fields: every line item is captured with description, quantity, unit price, tax rate, and line total.
Per-Field Confidence Scores
Each extracted value carries a confidence score — invoice total at 99.8%, dates at 99.3%, vendor name at 99.5% — so reviewers focus only on flagged fields.
How It Works
From connection to first extracted invoice in under five minutes
Documents Enter the Pipeline
Invoices arrive from email scanning, portal retrieval, forwarding addresses, or manual upload. The extraction engine is source-agnostic.
AI Produces Structured Output
The engine extracts vendor, amounts, dates, currency, tax, discounts, recipient, and every line item — delivering clean, structured JSON.
Verify and Approve
Review extracted data in the dashboard, edit any low-confidence field, then approve for export to your accounting tools or cloud storage.

Frequently Asked Questions
Inbox Ledger uses an OpenAI model purpose-configured for financial document comprehension. It analyzes both visual layout and text content, achieving 99.5%+ accuracy on standard digital invoices.
A multi-pass OCR pipeline preprocesses scanned PDFs, photographs, and low-resolution files before passing them to the AI. Quality influences accuracy, but the system is tuned for real-world conditions — not just clean digital originals.
The AI detects the invoice currency from the document. Daily exchange rates sourced from Open Exchange Rates convert the amount to your organization default currency. Both the original and converted figures are persisted.
No. The LLM-based engine interprets invoice structure without positional templates. A document from a previously unseen vendor is extracted with the same accuracy as one from a known supplier.
Standard output includes vendor name, invoice number, issue date, due date, currency, subtotal, tax, discount, total, recipient (bill-to) details, and all line items with description, quantity, unit price, and amount.
The underlying model was trained on financial documents spanning 50+ languages. It processes mixed-language invoices — for example, German headers with English line items — without manual language selection.
Typical single-page invoices finish in under 30 seconds. Multi-page documents with extensive line items may take up to 60 seconds. The pipeline processes multiple documents concurrently, so batch throughput scales linearly.
No. Your documents are processed through the AI extraction pipeline and the results are stored in your organization's database. Raw documents and extracted data are never used for model training, shared with third parties, or accessed by Inbox Ledger staff without explicit authorization. All processing is ephemeral — the AI model does not retain document content after extraction.
Yes. Inbox Ledger is GDPR-compliant. Your invoice data is encrypted both when stored and in transit. You can delete individual documents, entire workspaces, or request a full data export any time. Email passwords and connection tokens are kept encrypted, even from our team. For enterprise compliance needs, contact us.
When your credit balance reaches zero, new documents will not be processed until credits are replenished. Existing extracted data remains fully accessible — you can still view, export, and manage all previously processed invoices. To resume processing, purchase a credit bundle or upgrade your plan. No data is lost when credits are exhausted.
Manual invoice data entry typically takes 3 to 5 minutes per document and carries a 3 to 5 percent error rate. Inbox Ledger processes most invoices in under 30 seconds with 99.5%+ accuracy on standard documents. For a team processing 200 invoices per month, that translates to saving roughly 8 to 12 hours of manual work every month.
