DeepRead Invoice Processing

Extract structured data from invoices, receipts, purchase orders, and bills. Submit a PDF or image, get back typed JSON with vendor, line items, totals, tax, and due dates — with confidence flags telling you exactly which fields need human review.

This skill instructs the agent to POST documents to https://api.deepread.tech and poll for results. No system files are modified.

What You Get Back

Submit an invoice PDF and get structured JSON like this:

{
  "vendor": {"value": "Acme Corp", "hil_flag": false, "found_on_page": 1},
  "invoice_number": {"value": "INV-2026-0042", "hil_flag": false, "found_on_page": 1},
  "invoice_date": {"value": "2026-03-15", "hil_flag": false, "found_on_page": 1},
  "due_date": {"value": "2026-04-15", "hil_flag": false, "found_on_page": 1},
  "subtotal": {"value": 1150.00, "hil_flag": false, "found_on_page": 1},
  "tax": {"value": 100.00, "hil_flag": false, "found_on_page": 1},
  "total": {"value": 1250.00, "hil_flag": false, "found_on_page": 1},
  "currency": {"value": "USD", "hil_flag": false, "found_on_page": 1},
  "payment_terms": {"value": "Net 30", "hil_flag": true, "reason": "Inferred from dates"},
  "line_items": {"value": [
    {"description": "Consulting services - March", "quantity": 40, "unit_price": 25.00, "amount": 1000.00},
    {"description": "Software license", "quantity": 1, "unit_price": 150.00, "amount": 150.00}
  ], "hil_flag": false, "found_on_page": 1}
}

Fields with hil_flag: true need human review. Everything else is high-confidence and can be auto-processed.

Use Cases

• Accounts Payable — Auto-extract vendor, amount, due date from incoming invoices and route to approval
• Receipt Processing — Pull totals, dates, and vendor from expense receipts for reimbursement
• Purchase Orders — Match PO numbers and line items against invoices
• Bookkeeping — Bulk-process monthly invoices into structured data for your accounting system
• Audit — Extract and verify invoice data at scale with confidence scoring

Tips for Best Accuracy

• Be specific in descriptions — "Invoice number or reference ID" works better than just "number"
• Use YYYY-MM-DD for dates — Reduces ambiguity between US and international date formats
• Use blueprints for recurring vendors — If you process the same vendor's invoices repeatedly, create a blueprint at deepread.tech/dashboard/optimizer for 20-30% accuracy improvement
• Check hil_flag fields — These are the only fields that need human review. Everything else is high-confidence.

Batch Processing

For processing multiple invoices, submit them in parallel and collect results:

import requests
import json
import time
from concurrent.futures import ThreadPoolExecutor

API_KEY = "sk_live_YOUR_KEY"
BASE = "https://api.deepread.tech"
headers = {"X-API-Key": API_KEY}

schema = json.dumps({...})  # Use the invoice schema above

def process_invoice(file_path):
    with open(file_path, "rb") as f:
        job = requests.post(
            f"{BASE}/v1/process",
            headers=headers,
            files={"file": f},
            data={"schema": schema},
        ).json()

    job_id = job["id"]
    delay = 5
    while True:
        time.sleep(delay)
        result = requests.get(f"{BASE}/v1/jobs/{job_id}", headers=headers).json()
        if result["status"] in ("completed", "failed"):
            return result
        delay = min(delay * 1.5, 15)

# Process 10 invoices in parallel
invoice_files = ["invoice_01.pdf", "invoice_02.pdf", "invoice_03.pdf"]
with ThreadPoolExecutor(max_workers=5) as pool:
    results = list(pool.map(process_invoice, invoice_files))

for r in results:
    if r["status"] == "completed":
        data = r["result"]["data"]
        vendor = data.get("vendor", {}).get("value", "Unknown")
        total = data.get("total", {}).get("value", 0)
        print(f"  {vendor}: ${total}")
