Eliminate 90% of manual work in procurement by automating quote requests, response tracking, price extraction, and supplier follow-ups. This complete automation handles everything from sending personalized emails to extracting pricing data with AI and sending WhatsApp reminders—so you can focus on decision-making, not data entry. This all-in-one workflow transforms a 5-hour manual process into a 10-minute review task, saving 15-20 hours per month while improving supplier response rates by 30%. How it works This workflow contains 4 independent automation modules running on separate schedules: Quote Request Sender (Manual trigger) Reads supplier list from Google Sheets Sends personalized emails via Gmail with category and deadline Logs all requests with timestamps to tracking sheet Response Monitor (Hourly schedule) Automatically checks Gmail for supplier replies with attachments Updates tracking sheet status to "Quote Received" Zero manual email monitoring required AI Price Extraction (Manual trigger) Downloads PDF/Excel attachments from emails Extracts text using n8n's built-in parser Sends to OpenAI GPT-4o-mini to identify products, prices, quantities, currencies Saves structured data to Price Comparison sheet WhatsApp Follow-ups (Daily at 9 AM) Checks for non-responsive suppliers Sends smart reminders at Day 3, 5, and 7 with escalating urgency Falls back to email if no phone number Logs all follow-up history Each module shares data through Google Sheets while running independently. Set up steps Time to set up: 20-30 minutes Create two Google Sheets: "Quote Tracking" (with columns: supplier_name, supplier_email, category, request_date, status, quote_received, phone_number, last_follow_up, follow_up_count) and "Price Comparison" (with columns: supplier_name, supplier_email, product_name, price, currency, quantity, extracted_date, source_file) Connect credentials: Gmail OAuth, Google Sheets OAuth (same account), OpenAI API key, Twilio Account SID + Auth Token Update all Google Sheet IDs in every Google Sheets node (8 nodes total across all modules) Configure Twilio WhatsApp sandbox: Go to Twilio Console → Messaging → WhatsApp → Send join code from your phone → Update "From" number in Send WhatsApp node Add 2-3 test suppliers to Tracking Sheet with your email addresses using + trick (yourname+supplier1@gmail.com) and phone numbers in international format Test each module: Execute Quote Sender → Reply to test email with PDF → Execute AI Extraction → Set supplier date to 3 days ago → Test Follow-ups Activate schedules for Response Monitor (hourly) and Follow-ups (daily at 9 AM) Detailed node configurations and troubleshooting tips are included in sticky notes throughout the workflow canvas. Requirements Gmail account with API access Google Sheets (2 sheets) OpenAI API account (~$5-15/month) Twilio account with WhatsApp (~$10-20/month) n8n (any version supporting HTTP Request node) Who is this for Procurement teams managing multiple supplier quotes Small businesses comparing vendor prices Operations managers handling RFQs Purchasing departments drowning in email attachments Anyone collecting and tracking supplier pricing at scale Time savings: From 5 hours to 10 minutes per quote cycle (90% reduction) Response rate improvement: 50% → 80% with automated follow-ups Accuracy: 95%+ AI extraction accuracy vs 5-10% manual data entry errors.
