n8n Business Automation: 20 Workflows Every Business Should Run

Why n8n for Business Automation

n8n stands apart from simpler automation tools for business use because:

Self-hosting option: Your business data — customer records, financial information, internal communications — stays on your infrastructure. No third-party service sees your data.

Code when needed: JavaScript in Code nodes handles business logic that no point-and-click tool can express.

True automation depth: Not just trigger-action, but multi-step workflows with branching, loops, error handling, and AI.

Cost at scale: Zapier charges per task; at business scale this gets expensive. n8n self-hosted is free regardless of volume.
