Combined Three Popular n8n Templates Into One Document Intelligence System 🔥
Had three separate workflows: document classifier, data extractor, CRM poster. Running separately. Manual handoffs. Combined into single intelligent system. Processes 80 documents monthly automatically. THE ORIGINAL SETUP: WORKFLOW 1: Document Classifier Template (community template) - Receives document, classifies type, routes to folder WORKFLOW 2: Data Extraction Template (custom build) - Reads folder, extracts data, saves database WORKFLOW 3: CRM Agent Template (community template) - Queries database, posts CRM, notifies team Problem: Three workflows. Manual triggers. Documents stuck waiting. Manual monitoring needed. THE INTEGRATED SYSTEM: SINGLE WORKFLOW: Document arrives → Classify → Extract → Post to CRM → Notify. All automatic. Zero manual steps. THE INTEGRATION PATTERN: STAGE 1 - CLASSIFICATION (Template 1): Email trigger → document processing parse → AI classifier → Route by type (invoice, contract, form) STAGE 2 - EXTRACTION (Template 2): Receives classified doc → document processing extract structured data → Validate → Store Different schemas per type: Invoice (vendor, amount, date), Contract (parties, dates, obligations), Form (applicant info, responses) STAGE 3 - CRM POSTING (Template 3): Receives extracted data → CRM agent processes → Match existing records → Create or update → Notify INTEGRATION GLUE: Shared JSON schema across stages. Classification output feeds extraction. Extraction output feeds CRM agent. Unified error handling: Any failure → Route to review queue with context. Single monitoring: One dashboard showing queue depth, classification rate, extraction confidence, CRM status. BEFORE vs AFTER: BEFORE: Three workflows, manual coordination, documents waiting, 8 minutes per document, regular delays AFTER: One workflow, fully automated, zero waiting, 30 seconds per document, real-time processing THE NUMBERS: - Templates integrated: 3 - Integration time: 4 hours one-time - Documents monthly: 80 - Time saved: 8 hours monthly
