About this gig
Stop manually typing invoice data and chasing lost receipts!
I build automated AI Invoice and Expense Tracking pipelines using n8n, Gmail, OpenAI, and Google Sheets to streamline your financial workflow.

How the Workflow Works:
- Email Monitoring: Filters incoming PDF/image invoice attachments from Gmail.
- AI Extraction: Uses AI to parse vendor names, totals, dates, tax, and line items.
- Duplicate Check: Compares details against existing sheet records and skips duplicates.
- Sheet Logging: Appends clean, verified data to your expense spreadsheet.

FAQ
How does the AI extract data from my invoice attachments?
The n8n workflow monitors your incoming email inbox for PDF or image attachments and uses AI models (OpenAI or Claude) to read and extract structured details like vendor name, date, total amount, tax, and line items
How does the automated duplicate detection work?
Before adding any record to your spreadsheet, the workflow checks the extracted invoice number and vendor details against your existing Google Sheets entries and skips duplicate records to prevent double-logging
What file formats and email accounts are supported?
The system handles PDF, PNG, and JPEG invoice or receipt attachments received through Gmail or custom domain email accounts
Will I need ongoing paid subscriptions for third-party tools?
You will need an n8n workspace (cloud or self-hosted) and an OpenAI API key for document parsing, which costs only a fraction of a cent per processed invoice
Can you match the output columns to my existing spreadsheet template?
Yes! During setup, I map the extracted AI data fields directly to your existing Google Sheets column structure so your financial records stay consistent
