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 โ Extract attachments โ Parse Document โ Extract Structured โ Post to database โ Send confirmation
Used for: Invoices, quotes, applications, claims
TEMPLATE 2: Folder Monitoring with Batch Processing
Drive/Dropbox trigger โ Split Into Batches โ Parse per batch โ Merge results โ Bulk upload
Used for: High-volume document processing
TEMPLATE 3: Webhook Form Submission
Webhook trigger โ Download files โ Parse and extract โ Validation logic โ Multi-path routing
Used for: Application forms, registration, submissions
TEMPLATE 4: Scheduled Document Reports
Schedule trigger โ Fetch documents โ Parse multiple PDFs โ Aggregate data โ 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 โ Modify parameters โ 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)
- 10% workflow logic additions
I also maintain JSON Schema templates for extraction: invoice-standard.json, resume-basic.json, contract-terms.json. Copy schema โ Modify fields โ Use in workflow.
THE LESSON:
Build your n8n template library as you go. Every workflow you create, save as template. Document what's customizable.
Your 10th invoice processing client should take 1/10th the time of your first.
What n8n workflows are you rebuilding that could be templated?
