What Is Extract.co?

Extract.co is a general-purpose AI document extraction platform designed to pull structured data from any document type. Using large language models (LLMs), it can process PDFs, images, and scanned documents without requiring traditional template training.

The platform works by having users define the fields they want to extract from documents. You specify field names like "Invoice Number," "Date," "Total Amount," or any custom fields relevant to your documents. The AI then identifies and extracts those fields from uploaded documents.

Key Extract.co characteristics:

General-purpose extraction for any document type (invoices, contracts, receipts, forms, etc.)
Custom field definition via web interface or API
Pay-per-page pricing model that scales with usage
API-first design for developer integration
GDPR compliant with ISO 27001 certified infrastructure

Extract.co is ideal for developers and businesses processing diverse document types where flexibility and customization matter more than domain-specific features. For accounting-specific workflows, the platform extracts data but lacks built-in features like AI categorization, multi-account detection, or direct QuickBooks/Xero integration.

General Extraction vs Financial-Specific AI

Why purpose-built financial document AI outperforms general extraction for accounting workflows

Financial Document Intelligence

General Extraction (Extract.co)

General LLMs extract text but don't understand accounting context like "Opening Balance," "Ending Balance," or debit/credit conventions.

Financial-Specific (Zera Books)

Zera AI is trained specifically on bank statements, invoices, and financial documents. It understands accounting terminology and data relationships.

Bank Format Recognition

General Extraction (Extract.co)

You define extraction fields for each bank format. When formats change, you update definitions.

Financial-Specific (Zera Books)

Zera AI dynamically processes any bank statement format without template setup. Handles format changes automatically.

Accounting Workflow Features

General Extraction (Extract.co)

Extracts raw data. AI categorization, multi-account handling, and QuickBooks formatting are separate tools.

Financial-Specific (Zera Books)

AI categorization, multi-account auto-detection, and direct QuickBooks/Xero export are built-in features.

Real Results from Financial Document Processing

"We were drowning in bank statements from two provinces and multiple revenue streams. Zera Books cut our month-end reconciliation from three days to about four hours."

Manroop Gill

Co-Founder at Zoom Books

The Challenge

Zoom Books processes over 3 million books monthly across Canada and the US, with operations in British Columbia and Ontario. Managing financial data from multiple revenue streams—library partnerships, thrift store buybacks, wholesale operations—meant reconciling dozens of bank statements every month. The accounting team was spending 2-3 days just on manual data entry during month-end close.

Why General Extraction Didn't Work

With statements from multiple banks across different provinces and the US, setting up extraction rules for each bank format would have been time-consuming. They needed a solution that handled any bank statement format without configuration—and produced QuickBooks-ready data with proper categorization.

The Results with Zera Books

Reduced month-end close from 3 days to 4 hours
Processing 40+ bank statements monthly with zero manual entry
Eliminated reconciliation errors that delayed partner payments
ROI paid for itself in the first month from time savings
