What is n8n and Why We Use It to Automate Processes in SMEs

If you've been researching business process automation, you've probably come across names like Zapier, Make or Power Automate. They're good tools. But at EstructuraBit we use n8n, and there are concrete reasons for that.

What is n8n?

n8n is an open-source workflow automation platform. It lets you connect almost any application or system and automate processes without needing to code. It works with a visual interface where you design flows — called "workflows" — using blocks that represent actions: receive an order, query a database, send an email, update a record.

The key difference from other tools is that n8n can be installed on your own server. This means data doesn't leave your infrastructure, there are no artificial monthly execution limits, and you don't depend on a third party raising prices.

What kinds of processes can n8n automate?

n8n can automate almost any process that today requires a person to copy information from one place to another, send a manual alert or execute a repetitive task. Some concrete examples:

• When a WooCommerce order comes in, automatically create the invoice in Zoho Books and notify the warehouse via WhatsApp
• When a customer fills in a web form, create the contact in the CRM and assign a task to the salesperson
• When a product's stock drops below a threshold, send an alert email to the purchasing manager
• Every Monday at 8:00, generate a previous week's sales report and send it by email
• When a document is uploaded to Google Drive, automatically move it to the correct folder and notify the team

Why n8n and not Zapier or Make?

Zapier and Make are excellent for businesses that want to start quickly with simple flows. The problem appears when the business grows:

• Scalable cost: Zapier and Make charge per number of executions. As flows are used more, the bill grows. With self-hosted n8n, the cost is fixed.
• Data control: In sectors with sensitive data — legal, healthcare, industrial — data must not leave to third-party servers. With n8n on your server, everything stays in-house.
• No artificial limits: n8n does not limit the number of workflows, executions or active nodes.
• Technical flexibility: n8n allows JavaScript code to run inside flows when the logic is more complex — something Zapier doesn't allow.

Does your business need a technician to maintain it?

Once installed and configured, n8n is managed from a web interface without needing to touch any code. Flows can be modified, activated or deactivated from the browser. For server maintenance, technical support is recommended — which is exactly what EstructuraBit offers.

How much does it cost to implement n8n in a business?

The software is free in its self-hosted version. The cost lies in the initial implementation — installation, configuration and flow design — and in subsequent support if needed. In most cases, the investment is recovered within the first few months thanks to the time saved.
