Automated Invoice Generator: Google Sheets to Docs

This n8n workflow streamlines invoice generation by extracting structured data from a Google Sheet—including company details, terms, invoice number, description, and amount—and merging it into a pre-designed Google Docs template. It starts with a manual trigger for testing, loads invoice data via Google Sheets node, retrieves the template document, creates a new Doc copy in a specified Drive folder, and merges the data by replacing placeholders like FromCompany#, ToCompany#, etc. The result is a ready-to-use invoice document automatically saved to Google Drive.

Benefits include significant time savings for freelancers, small businesses, or accounting teams who generate invoices repeatedly. It eliminates manual copying, reduces errors from data entry, ensures consistent formatting via templates, and scales easily for batch processing multiple rows. No coding required beyond n8n setup, with OAuth credentials for seamless Google integration.

Use cases: Monthly billing for services, client invoicing in consulting firms, automated HR vendor payments (despite HR category), or any scenario needing templated docs from spreadsheets. Customize sheet columns, template placeholders, and folder IDs for your needs; supports high-volume automation with workflow triggers like webhooks.
