Been building document workflows for 10 months. Realized I was rebuilding similar patterns repeatedly. Created n8n template library. Now new client workflows take 45 minutes instead of 4 hours. MY TEMPLATE LIBRARY: TEMPLATE 1: Email Attachment Processing Email trigger → Extract attachments → Parse Document → Extract Structured → Post to database → Send confirmation Used for: Invoices, quotes, applications, claims TEMPLATE 2: Folder Monitoring with Batch Processing Drive/Dropbox trigger → Split Into Batches → Parse per batch → Merge results → Bulk upload Used for: High-volume document processing TEMPLATE 3: Webhook Form Submission Webhook trigger → Download files → Parse and extract → Validation logic → Multi-path routing Used for: Application forms, registration, submissions TEMPLATE 4: Scheduled Document Reports Schedule trigger → Fetch documents → Parse multiple PDFs → Aggregate data → Email report Used for: Client reporting, compliance summaries HOW I USE TEMPLATES: Client request: "Process supplier invoices from email" Process: 1. Copy Template 1 (Email Attachment Processing) 2. Update email address in trigger 3. Modify JSON Schema for their invoice fields 4. Change database credentials to their system 5. Test with 3 sample invoices 6. Deploy Time: 32-45 minutes average. Before templates: 3-4 hours building from scratch. THE n8n ADVANTAGE: Workflows export/import as JSON. I keep library of base templates. Import → Modify parameters → Deploy. Found additional template examples at here that had common schemas already configured. RESULTS AFTER TEMPLATES: Month 1-4 (before templates): 4 clients built, 16 hours total Month 5-8 (with templates): 11 clients built, 14 hours total Month 9-10: 7 clients built, 6 hours total Same pricing to clients. Drastically reduced delivery time. CUSTOMIZATION BREAKDOWN: - 70% of template stays exactly the same - 20% parameter changes (emails, credentials, field names)
