Generate PDF Invoices from Google Sheets with ReportFlow (n8n)

Generate PDF Invoices from Google Sheets with ReportFlow in n8n

This workflow lets you manually trigger invoice processing in n8n, pull invoice rows from Google Sheets, and send them to ReportFlow to generate PDF invoices asynchronously using your chosen design template.

What this workflow does

• Manual start in n8n: Runs when you execute the workflow manually.
• Reads your configuration: Uses configured fields to get the Google Sheets URL and the ReportFlow design ID.
• Fetches invoice row data: Pulls invoice details from the specified Google Sheets document and sheet.
• Sends each row to ReportFlow: For each invoice row, the workflow submits the invoice details to ReportFlow to generate one or more PDF files based on the selected design template—asynchronously.

Use cases

• SaaS invoicing ops: Create invoices in a shared Google Sheet and generate customer-ready PDFs on demand.
• Freelance billing: Maintain invoice line items in Google Sheets, then produce branded PDF invoices through ReportFlow designs.
• Automation engineers: Provide a simple, manual “invoice PDF generation” workflow for internal teams without building a full invoicing UI.

Technical details

• Google Sheets integration to read invoice rows from your spreadsheet.
• ReportFlow integration (via n8n-nodes-reportflowreport flow) to generate PDFs from a selected design template.
• n8n nodes used: Manual Trigger, google sheets, set, and the n8n-nodes-reportflowreport flow node.
• Setup steps: (1) Copy the provided Google Sheets template, (2) duplicate the ReportFlow template to your account, (3) add your Google Sheets OAuth credential, and (4) add a ReportFlow AppKey credential. Then update the “Edit Fields” node with your SheetURL and DesignId.

Perfect for n8n automation workflows that need reliable PDF invoice generation from Google Sheets using ReportFlow.
