Your Gmail Holds Hundreds of Invoices. AI Finds Every One.
Authorize read-only access through Google Sign-In and Inbox Ledger scans your entire Gmail history for financial attachments. The Gmail History API delivers incremental sync after the initial import — cutting subsequent scan volume by 95%+ while AI pre-classification filters out non-financial noise before credits are consumed.
Key Gmail Invoice Scanner Capabilities
Built-in functionality that eliminates repetitive document tasks
Google Sign-In — Read-Only
Authenticate through Google's official OAuth flow with the gmail.readonly scope. Inbox Ledger cannot send, delete, or modify emails — your inbox remains untouched.
AI Pre-Classification Filter
A lightweight classifier evaluates every attachment before extraction begins. Marketing decks, slide presentations, and non-financial PDFs are discarded — only invoices and receipts consume credits.
Gmail History API Incremental Sync
The initial scan covers your full Gmail archive. After that, the History API fetches only newly arrived messages — cutting subsequent sync volume by 95%+ and preserving your credit balance.
15-Field Structured Extraction
Each document yields vendor name, invoice number, issue and due dates, currency, subtotal, tax, discounts, total amount, and individual line items — powered by our core AI extraction engine with per-field confidence scoring.
Multi-Language & Multi-Currency
Invoices in English, German, Japanese, Arabic, Chinese, and dozens of other languages are processed seamlessly — including mixed-language and RTL documents. See the Multi-Language Processor for full language details.
Background Parallel Processing
Detected attachments are queued and processed in parallel. Continue working while AI extracts data in the background — multi-page documents are handled alongside single-page invoices.
Document Types Extracted from Gmail
AI identifies and extracts data from every supported format
Supplier & Vendor Invoices
B2B invoices from SaaS providers, logistics companies, agencies, and wholesale suppliers — PDF attachments or inline email invoices.
E-Commerce Receipts
Order confirmations from Amazon, Shopify storefronts, and online marketplaces — including embedded receipt PDFs and confirmation attachments.
Recurring SaaS Billing
Monthly and annual invoices from AWS, Google Workspace, Slack, Zoom, and other subscription platforms delivered automatically to Gmail.
Credit Notes & Refunds
Vendor-issued credit memos and refund documents are identified, tagged as credits, and extracted with correctly signed amounts.
Utility & Telecom Invoices
Electricity, internet, mobile, and other recurring utility bills arriving as PDF attachments in your Gmail inbox.
Contractor & Freelancer Invoices
Invoices from external consultants, freelancers, and agencies — in varied formats, languages, and currencies — all handled by the same engine.

Frequently Asked Questions
Inbox Ledger requests only the gmail.readonly scope through Google Sign-In. It reads email attachment metadata and downloads PDF files for processing. It cannot send, modify, or delete any messages. You can revoke access at any time from your Google account settings.
Gmail attachments pass through the same AI extraction engine that powers all Inbox Ledger tools. Per-field confidence scores flag any values that may need review. For detailed accuracy benchmarks, see our AI Invoice Extractor page.
No. You can connect as many personal Gmail and Google Workspace accounts as your organization requires. Each account maintains an independent sync cursor and processing queue, so additional accounts have no impact on existing scan speed.
Before extraction begins, a lightweight AI pre-classifier evaluates every attachment. Documents identified as non-financial — marketing PDFs, slide decks, images — are skipped automatically and do not consume processing credits.
The first scan processes your entire Gmail history available through the API. Years of archived invoices are retrieved and extracted. After the initial pass, the Gmail History API handles incremental updates — only new messages are fetched.
Yes. Personal Gmail accounts and Google Workspace accounts — including shared team inboxes and department mailboxes — use the same OAuth flow and API. The scanning behavior is identical across all account types.
You can trigger a manual re-sync at any time or upload the PDF directly through the dashboard. The pre-classifier errs on the side of caution, so borderline documents can be reprocessed manually without additional configuration.
Incremental sync picks up new emails within minutes of arrival. Each document is extracted and delivered as structured data shortly after. You can also run an on-demand sync for immediate processing when needed.
