What DocPeel extracts

No fixed columns or rigid schema. The LLM reads your document and returns clean, structured JSON automatically — or you define your own template to control the exact output shape.

Smart auto-extraction
Upload any document and the LLM intelligently surfaces all relevant data as clean JSON. No schema setup, no field mapping — it adapts to whatever your document contains.
Custom templates
Need specific field names, data types, or a fixed output structure? Define a template once and every extraction follows your schema exactly.

The real cost of manual invoice processing

Accounts payable teams spend an average of 8–12 minutes manually keying a single invoice. Multiply that by hundreds of invoices a month — many arriving as scanned PDFs, email attachments, or photographed receipts — and the hours add up fast.

Beyond the time cost, manual entry introduces errors that ripple through reconciliation, audit trails, and supplier relationships. A mis-keyed total or wrong due date can trigger a duplicate payment, a late-payment penalty, or a strained vendor relationship.

DocPeel eliminates that loop. Upload the invoice or forward the email, and every field is extracted in seconds — no template mapping, no rules engine, no per-vendor configuration.

How DocPeel handles every invoice format

Invoices do not arrive in a standard format. Some vendors send structured PDFs, others send scanned images, and many send HTML emails with the invoice body inline. DocPeel handles all three without configuration.

For scanned documents and photographs, the AI layer corrects skew, enhances contrast, and reads low-resolution text before extraction. For digitally generated PDFs, the model reads native text layers directly for maximum accuracy. Email invoices are parsed from both plain text and HTML, with attached PDF or image invoices processed in the same job.

Line-item tables — the part that trips up almost every template-based system — are extracted as structured arrays, preserving quantity, unit price, description, and total for each row.

Connecting to your accounting stack

Extracted invoice data needs to land in the right system immediately to be useful. DocPeel ships native integrations with Google Sheets (for lightweight review workflows), Dropbox (for archiving), and webhook delivery that maps cleanly to QuickBooks, Xero, Sage, and NetSuite ingestion endpoints.

For teams building custom AP pipelines, the REST API returns a clean JSON payload that can be posted directly to any ERP or BMS. Each field includes a confidence score, so you can automatically flag low-confidence extractions for human review before they reach the ledger.

Multi-currency and international invoices

DocPeel works in 60+ languages and supports all major currency formats. EUR invoices with commas as decimal separators, INR invoices with lakh notation, and JPY invoices without decimal points are all handled correctly without any per-locale configuration.

Tax formats — VAT, GST, sales tax, withholding tax — are individually identified and mapped to separate fields rather than collapsed into a single total, giving your finance team the granularity needed for correct tax reporting.

Frequently asked questions

Can DocPeel extract line items from complex tables?

Yes. Line items are extracted as structured arrays with individual fields for description, quantity, unit price, tax rate, and line total — even when table layouts vary significantly between vendors.

What happens when the invoice is a low-quality scan?

DocPeel applies image pre-processing — deskewing, contrast enhancement, and noise reduction — before running extraction. Most legible scans achieve the same accuracy as native PDFs.

Does it work with invoices in languages other than English?

Yes. DocPeel supports extraction from invoices in 60+ languages, including German, French, Spanish, Japanese, Arabic, and Chinese, without any language-specific configuration.

How do I handle invoices I receive by email?

Forward them to your DocPeel inbound email address. The parser processes both the email body and any attached PDF or image invoices in a single job.
