Zera AI — The Core Engine
The Zera AI engine is what separates Zera Books from converters built on generic PDF parsing. It was trained on 3.2 million financial documents: 2.8 million bank statements from hundreds of institutions, 420,000 invoices, and a combined 847 million individual transactions.
That training volume matters because bank statement formats vary enormously. Chase formats its statements differently from RBC, TD, PNC, and Scotiabank. Within a single bank, the format can shift when the institution updates its PDF template. A tool built on rules and templates breaks at that point. Zera AI identifies column structure, header patterns, and transaction rows dynamically — it doesn't rely on a fixed map.

Document Types and Input Formats
Most document processing tools are built around one use case and bolted onto others. Zera Books was architected from the start to handle four document types — because that's what accounting workflows actually require. You don't process bank statements in isolation; you're reconciling them against invoices and checking them against financial reports.
| Document Type | Fields Extracted | Accepted Input |
|---|---|---|
| Bank Statements | Date, description, debit, credit, running balance, account number, opening/closing balance | Digital PDF, scanned PDF, JPG, PNG, multi-page, password-protected |
| Financial Statements | Line items, period headers, account codes, subtotals, comparative column data | Digital PDF, scanned PDF |
| Invoices | Vendor name, invoice date, invoice number, line items, quantities, unit prices, tax amounts, PO number, payment terms | Digital PDF, scanned PDF, JPG, PNG |
| Checks | MICR routing number, account number, check number, payee, amount in numerals and text, date, memo field | Scanned PDF, JPG, PNG |
Batch input: Upload 50+ documents simultaneously. The platform processes them in parallel and returns output files organized by document type and client. See client management reference for dashboard organization details.

There are two tiers of integration: direct API connections where data flows automatically into your accounting software, and pre-formatted exports where the file is structured to match the import requirements of the target system.
QuickBooks Online — Direct API
Categorized transactions pushed directly into QBO. No export/import cycle, no manual field mapping. Includes auto-categorization mapped to your existing chart of accounts.
Xero — Direct API
Same direct pipeline for Xero. Transactions categorized against your Xero chart of accounts with confidence scoring. Review and approve before import.
Pre-Formatted Exports
Sage, Wave, Zoho, NetSuite, FreshBooks, MYOB, Oracle, IIF (QuickBooks Desktop). Each export matches the exact column structure required for a clean import. No manual mapping needed.
Universal Export Formats
Excel (XLSX), CSV, QBO, IIF. All include auto-categorized transaction data. PDF to Excel specs and PDF to CSV specs on separate reference pages.
Workflow Features
The platform features beyond extraction are what make Zera Books suitable for practices with 10+ clients. Single-document converters don't scale — you need organization, history, and batch capability built in.
Multi-account auto-detection
A single PDF containing checking, savings, and credit card data is automatically identified and split into separate output files. No manual page-range selection.
Duplicate detection
Overlapping statement periods are common when clients provide statements that cover the same date range from multiple sources. The deduplication engine compares transaction date, amount, and description to flag and remove duplicates before export.
Data standardization
Date formats vary by bank and region (MM/DD/YYYY vs DD/MM/YYYY vs MMM DD, YYYY). Description text contains bank-specific reference codes and truncations. The platform normalizes both to a consistent format across all output files.
Audit trail
Every conversion is logged with timestamp, source file name, user account, and output files generated. Unlimited conversion history — useful for firms with regulatory record-keeping requirements.
Security Architecture
Financial documents contain sensitive client data. The Zera Books security model is built around three principles: encryption at every layer, minimal data retention, and explicit permission before anything is stored beyond the processing window.
AES-256 Encryption
All data encrypted in transit (TLS 1.3) and at rest (AES-256). No plaintext storage at any layer of the stack.
30-Day Auto-Delete
Uploaded files are automatically deleted after 30 days. No data retained beyond that window without explicit account holder permission.
No Sharing Without Permission
Uploaded documents and extracted data are not used to train models or shared with third parties without explicit opt-in.
Conversion Audit Log
Every document processed is logged with timestamp and account identifier. Supports internal compliance reviews and client record-keeping requirements.
Frequently Asked Questions
What document types does Zera Books process?
Four types: bank statements, financial statements (P&L, balance sheets, cash flow), invoices with line-item extraction, and checks with MICR data. Most competitors process only bank statements.
Does Zera Books require template setup for new banks?
No. Zera AI identifies document structure dynamically. It adapts to format changes and previously unseen layouts without any configuration. See Zera AI reference for model details.
What accounting software does Zera Books connect to?
Direct API integration with QuickBooks Online and Xero. Pre-formatted exports for Sage, Wave, Zoho, NetSuite, FreshBooks, MYOB, and Oracle. All exports include AI-categorized transactions with no manual field mapping.
How is client data protected?
AES-256 encryption in transit and at rest. Files auto-deleted after 30 days. No data sharing without explicit permission. Full details at zerabooks.com/platform.
