How It Works

End-to-end invoice automation pipeline

From inbox to accounting system, without touching a spreadsheet.

Receive invoice

Via file path, URL, or buffer through the API. Route invoices programmatically from your email, S3, or ERP system.

Extract fields

AI extraction returns vendor, amounts, dates, and line items as JSON.

Validate & route

Use extracted fields in your system to cross-reference purchase orders, apply approval rules, or flag discrepancies.

Push to your system

POST structured JSON to your accounting API, ERP, or automation platform.

Quick Start

From invoice PDF to accounting entry in one API call

Define your invoice template once. Then submit invoices via REST API or SDK and receive structured JSON instantly — or asynchronously via webhook.

  • Vendor name, address & VAT ID
  • Invoice number, date & due date
  • Subtotal, tax amount & total
  • Full line items array
  • Payment terms & bank details

process-invoice.ts
const result = await client.documents.parse({
  templateId: 'tpl_invoice',
  file:       './invoice.pdf',
});

// Push to QuickBooks
await quickbooks.bills.create({
  VendorRef:  result.data.vendor_name,
  TotalAmt:   result.data.total_amount,
  DueDate:    result.data.due_date,
  Line:       result.data.line_items,
});

Frequently asked questions

All about automated invoice processing with Parselyze.

What is automated invoice processing?

Automated invoice processing is the use of AI and API integrations to extract, validate, and route invoice data without manual data entry. Documents are parsed into structured JSON, ready to push to your accounting system.

How does the Parselyze automated invoice processing API work?

You submit an invoice PDF or image via REST API or SDK. Parselyze extracts all fields — vendor, invoice number, amounts, due date, and line items — and returns structured JSON. Results can also be delivered via webhook for async workflows.

Can Parselyze handle high-volume invoice processing?

Yes. The synchronous endpoint accepts up to 10 files per request, and the async endpoint processes individual files non-blocking with webhook delivery. Submit multiple parseAsync() calls in parallel to handle hundreds of invoices without blocking your server.

What accounting systems does Parselyze integrate with?

Parselyze returns standard JSON that your code can push to any accounting API — QuickBooks, Xero, SAP, Oracle NetSuite, Sage, FreshBooks, or any other system. For no-code automation, use Zapier or Make.

Does automated invoice processing require custom model training?

No. Parselyze uses zero-shot AI extraction that works across invoice formats out of the box. You define your template fields once in the dashboard and extraction begins immediately — no training data or ML expertise required.
