How BookZero works 4-step pipeline showing Import, AI Extraction, Matching, and Reports stages
Four steps from raw receipts to tax-ready reports — most of it automated by AI

Step 1: Import Your Receipts

BookZero connects to Google Drive, Dropbox, and Amazon S3 so you can import receipts directly from where you already store them. You can also drag-and-drop files from your computer.

Supported formats include JPG, PNG, PDF (single and multi-page), and HEIC. Once imported, files are queued for AI processing — most receipts are fully extracted in under 5 seconds.

Step 2: AI Categorization

The AI reads each receipt and extracts:

AI extracts every field from your receipt and maps the expense to the correct T2125 category
  • Vendor name (e.g., Shell, Costco, Amazon)
  • Date and total amount
  • Tax breakdown — GST, HST, PST detected by province
  • Category — mapped to CRA T2125 line numbers (fuel, office supplies, meals, etc.)
  • Payment method — Visa, Mastercard, cash, etc.

You can review and correct any field. BookZero learns from your corrections and applies them to future receipts from the same vendor.

Step 3: Bank Statement Matching

Import your bank statement (CSV or PDF) and BookZero parses every transaction automatically. Then the auto-match engine compares each transaction against your receipts by date, amount, and vendor.

Matches are scored and presented for one-click confirmation. For transactions without a clear match, you can drag-and-drop to manually pair them.

Step 4: Export Tax-Ready Reports

Once your receipts and transactions are matched, export everything as a CRA-ready report. Reports include:

  • Expense summary by category
  • Tax collected (GST/HST/PST) by period
  • Matched vs. unmatched transaction breakdown
  • CSV and PDF export options

Whether you file yourself or hand it to your accountant, BookZero gives you organized, audit-ready data that meets CRA record-keeping requirements.

Frequently Asked Questions

How long does BookZero take to scan a receipt?

Under 5 seconds per page. BookZero uses Google Gemini AI to extract vendor name, amount, date, taxes (GST/HST/PST), payment method, and category from each receipt image. Multi-page receipts (up to 30 pages) are processed page-by-page and merged automatically.

Can BookZero handle handwritten or faded receipts?

Yes. Unlike traditional OCR that relies on clear printed text, BookZero's AI understands context — it can read handwritten receipts, faded thermal paper, and crumpled invoices. Each extracted field includes a confidence score (0.7–1.0) so you can see which fields may need review.

What file formats does BookZero accept?

BookZero accepts JPG, PNG, and PDF files. Single images cost 1 credit. Multi-page PDFs cost 1 credit per page (maximum 30 pages per file). You can upload directly, or import from Google Drive, Dropbox, or Amazon S3.

Does BookZero work with Canadian bank statements?

Yes. BookZero imports bank statements in CSV and PDF formats from any Canadian bank. It automatically matches imported transactions to your scanned receipts using AI, so you can reconcile your books without manual rule-building.
