Why n8n

The platform that owns all your flows

n8n is the open-source automation platform replacing Zapier and Make at serious companies. It connects 400+ services, runs advanced conditional logic, integrates AI (OpenAI, Anthropic, Ollama), processes WhatsApp Business webhooks and writes into CRMs like Supabase, Airtable, HubSpot — or a custom one.

For B2B teams, n8n has three critical advantages: self-hosted (no dependency on a foreign vendor or USD billing per seat), visually transparent flows (your team understands the system without code), and extensible (custom nodes are trivial if you need to integrate niche tools).

Real case: JL Mercantil with n8n + AI + WhatsApp

At JL Mercantil (technology and energy, Medellín) I built an n8n workflow that captures the WhatsApp webhook, routes it through OpenRouter AI, extracts intent and lead data, writes to a Supabase CRM, decides whether the bot replies or hands off to a human, and notifies the responsible sales rep. All under 2 seconds per message. It now processes 400+ daily messages.

The most requested flows

Every company has its own mix of tools. These are the workflows I deploy most often:

WhatsApp → AI → CRMWebhook captures the message, AI filters and replies, CRM logs and notifies the team.

Meta Ads → CRM → EmailLead arrives from Meta Ads, gets auto-qualified and triggers a follow-up email sequence.

Web form → CalendarThe lead self-schedules and receives a Google Meet link with automated reminders.

Pipeline stage → Slack/WhatsAppStage changes trigger real-time notifications to the responsible rep.

Automated daily reportsA cron job pulls KPIs and emails the CEO a morning summary by email or WhatsApp.

Self-hosted on Hostinger or any VPSI deploy n8n on Colombian or international infrastructure based on your data preferences.

Real metrics

JL Mercantil — 400 msgs/day handled in 4 days

A technology and energy company drowning in roughly 400 daily messages from Meta Ads. I designed a bot + Supabase CRM in four days, with an n8n workflow wired to OpenRouter AI, the WhatsApp Business API and team notifications.

Frequently asked questions

What people ask the most

What is n8n and why are companies adopting it?+

n8n is an open-source workflow-automation platform that connects tools like WhatsApp, CRMs, Google Calendar, email and AI models. Companies adopt it to escape vendor lock-in from Zapier or Make and to keep full control of their data.

Which n8n workflows are most useful for an SMB?+

The most requested: WhatsApp Business → AI → CRM, web form → lead qualification → sales-rep notification, Meta Ads → CRM → automated email, scheduling → Google Calendar → reminder, and daily reports with live pipeline metrics.

Can I host n8n on my own server?+

Yes. n8n can be deployed on any VPS (Hostinger, AWS, DigitalOcean) or even on a mini PC at the office using Docker. For privacy-sensitive clients I run n8n locally next to Ollama for fully private AI.

What does it cost to implement n8n?+

It depends on workflow count and customization depth. The self-hosted n8n license is free; the real cost is consulting and implementation. The 30-minute discovery call is free and we scope the range from there.
