This enterprise-grade n8n workflow automates the Pharmaceutical Raw Material COA Verification & Vendor Quality Scoring System — from upload to final reporting — using AI-powered document extraction , specification matching, and dynamic vendor scoring. It processes Certificates of Analysis (COAs) to validate compliance, assign quality scores, generate approvals or CAPA requests, and notify stakeholders, ensuring regulatory adherence and vendor accountability with full audit trails and zero manual data entry. Key Features Webhook-triggered COA Upload for seamless integration with file-sharing systems AI Document Extraction to parse test results and data from uploaded COAs Automated Specification Analysis matching against predefined quality standards Weighted Vendor Scoring based on compliance metrics and historical performance Compliance Decision Engine with approve/reject branching and CAPA flagging Dynamic Certificate Generation for approved materials, including digital signatures Vendor Database Synchronization to update scores and records in real-time Targeted Email Notifications for QA, production, and executive teams Executive Reporting Dashboard with summaries, scores, and verification logs Audit-Ready Logging for all steps, deviations, and decisions Workflow Process Step Node Description 1 START: Upload COA Webhook trigger receives uploaded COA file for verification process 2 EXTRACT: Parse COA Extracts test results and data from the COA document using AI parsing 3 ANALYZE: Vendor Compliance Compares extracted data against specifications and flags deviations 4 SCORE: Vendor Quality Rating Calculates weighted compliance score based on test results and history 5 DECISION: Compliance Route Evaluates score/status: Branches to approve (green) or reject (red) path 6 APPROVED: Generate Approval Cert (Approved Path) Creates digital approval certificate for compliant materials 7 Update Vendor Database Saves verification record, score, and status to vendor database 8 NOTIFY: Email Alert Sends detailed notifications to QA/production teams 9 REPORT: Final Report Generates executive summary with COA scores and verifications 10 REJECT: Generate Rejection Report (Reject Path) Produces rejection report with deviation details 11 Request CAPA Initiates Corrective and Preventive Action (CAPA) process 12 PATH REJECTED Terminates rejected branch with audit log entry Setup Instructions 1. Import Workflow Open n8n → Workflows → Import from Clipboard Paste the JSON workflow 2. Configure Credentials Integration Details File Storage (e.g., Google Drive/AWS S3) API key or OAuth for COA upload handling AI Extraction (e.g., Claude or OCR Tool) API key for document parsing (e.g., claude-3-5-sonnet-20241022 ) Database (e.g., PostgreSQL/Airtable) Connection string for vendor records and specs Email (SMTP/Gmail) SMTP credentials or OAuth for notifications 3. Update Database/Sheet IDs Ensure your database or Google Sheets include: VendorDatabase for scores and history Specifications for quality standards 4. Set Triggers Webhook: /coa-verification (for real-time file uploads) Manual/Scheduled: For batch processing if needed 5. Run a Test Use manual execution to confirm: COA extraction and analysis Score calculation and branching Email notifications and report generation (use sample COA file) Database/Sheets Structure VendorDatabase | vendorId | coaId | score | complianceStatus | lastVerified | deviations | capaRequested | |--------------|-------------|----------|--------------------|--------------------|--------|--------------------|---------------| | VEND-123456 | COA-789012 | 92.5 | Approved | 2025-11-04T14:30:00Z | None | No | Specifications | materialType | testParam | specMin | specMax | weight | |--------------|-------------|----------|--------------------|--------------------|--------|--------------------|---------------|----------| | API Excipient | Purity (%) | 98.0 | 102.0 | 0.4 | System Requirements Requirement Version/Access n8n v1.50+ (AI and database integrations supported) AI Parsing API claude-3-5-sonnet-20241022 or equivalent OCR Database API SQL connection or Google Sheets API Email API https://www.googleapis.com/auth/gmail or SMTP File Storage AWS S3 or Google Drive API access Optional Enhancements Integrate ERP Systems (e.g., SAP) for direct material release Add Regulatory Export to PDF/CSV for FDA audits Implement Historical Trend Analysis for vendor performance dashboards Use Multi-Language Support for global COA extraction Connect Slack/Teams for real-time alerts beyond email Enable Batch Processing for high-volume uploads Add AI Anomaly Detection for predictive non-compliance flagging Build Custom Scoring Models via integrated ML tools Result: A fully automated quality assurance pipeline that verifies COAs, scores vendors, and drives compliance decisions — ensuring pharmaceutical safety and efficiency with AI precision and complete traceability.
