This workflow automatically pulls invoice rows from Google Sheets and generates a PDF invoice using a PDF.co template.
Perfect for small businesses that manage invoices in Sheets but need professional, ready-to-send PDFs.

⚙️ Setup Instructions

1️⃣ Connect Google Sheets

  1. Copy this Invoice Template Sheet into your own Drive
  2. In n8n → Credentials → New → Google Sheets (OAuth2)
    • Log in with your Google account and save
  3. In the workflow, select your Spreadsheet ID and Worksheet (Sheet1) in the Google Sheets node

2️⃣ Connect PDF.co

  1. Create a free account at PDF.co
  2. Copy your API Key from the dashboard
  3. In n8n → Credentials → New → PDF.co API
    • Paste your API Key → Save
  4. In the PDF.co node, select your credential and choose the HTML Template to PDF operation

3️⃣ Create Your PDF.co HTML Template

  1. In your PDF.co dashboard, go to Templates → New Template
  2. Paste in the HTML from the template section below
  3. Save the template and copy its Template ID
  4. Replace the templateId in the workflow with your new ID

🧠 How It Works

  • Get Invoice Rows → Reads your Google Sheet rows (customer, line items, totals)
  • Convert to HTML Import (Code node) → Formats rows into structured data for the invoice template
  • Create PDF (PDF.co) → Sends the data into PDF.co and generates a professional PDF invoice
