Automate Invoicing with n8n, Stripe and QuickBooks
This technical how-to explains how to build a hands-off invoice→payment pipeline using n8n (self-hosted), Stripe, QuickBooks Online, and an SMTP provider (e.g., Gmail). The guide provides step-by-step instructions: provision n8n via Docker, create API credentials for Stripe and QuickBooks, design an automated nightly workflow to find overdue Stripe invoices, create QuickBooks sales receipts, and send escalating email reminders (1, 7, 14 days). It includes an example n8n node JSON, common failure modes (rate limits, expired OAuth tokens, SMTP auth failures), testing advice (MailHog), and optional PayPal or auto-charge flows. Estimated build time is 3–4 hours and the article links to a downloadable template and pre-configured n8n JSON.
Practical technical tutorial for automating invoicing and payment workflows; useful for SMBs and ops teams but not industry-shifting for AdTech/MarTech.

Author Shares 10 Practical n8n Workflow Templates
A developer published ten fully functional n8n workflow templates (provided as single JSON files) that they use daily on a self‑hosted n8n instance (Docker on a single Hetzner VPS). The post includes three embedded templates — a GPT‑powered sentiment email auto‑reply, a DSGVO/GDPR compliance scanner, and a Clearbit-enriched lead qualification pipeline — and describes seven additional templates (invoice OCR, RSS multi‑channel publisher, DB backups to S3‑compatible storage, Stripe onboarding, API health monitoring with Grafana, social listening to Notion, and error aggregation/alerting). The author reports production results after six months (≈15 hours/week saved, email response time reduced, 200+ sites scanned for DSGVO checks) and offers a packaged download and advanced template pack with documentation.
n8n Guide: Self-Hosted Workflow Automation with AI
This technical guide explains how to use n8n, a fair-code, developer-first workflow orchestration tool, to automate business processes from simple webhooks to multi-agent AI enrichment. It covers core advantages (self-hosting for data sovereignty, native JavaScript/Python nodes, complex data handling), a Docker Compose example for quick self-hosted deployment, a real-world lead-processing architecture with AI enrichment and CRM routing, and production best practices (idempotency, error triggers, queueing, secure credentials). The article emphasizes native AI orchestration via integrations with LangChain, OpenAI, Claude, and local vector databases and offers operational patterns for scaling high-throughput workflows.
