n8n agency

n8n agency: your automation workflows, designed, deployed and maintained.

Merlin builds n8n workflows plugged into the tools you already use (CRM, e-mail, spreadsheets, ERP) then puts them into production and keeps watch. On n8n Cloud, or self-hosted on your servers so your data stays with you.

The tool

What n8n is, and why we often recommend it.

n8n is an open-source workflow automation tool. It connects your applications through hundreds of native integrations, runs complex scenarios (conditions, loops, queues) and lets you plug AI models into the middle of a process. Its decisive trait: it can be hosted on your own servers.

  • Self-hosting available : your instance on your infrastructure or a dedicated EU server: your data never passes through a third-party SaaS.
  • No per-execution cost : unlike SaaS billed per operation, a self-hosted n8n workflow can run thousands of times a day without inflating the bill.
  • Code when you need it : where no-code tools hit their ceiling, n8n accepts JavaScript or Python inside a workflow. That is where our developer DNA makes the difference.
  • AI built in : dedicated nodes for AI models and agents: an n8n workflow can read, classify, summarise, reply.

n8n, Make or Zapier? Make and Zapier are simpler to pick up, but only exist as SaaS. n8n wins as soon as you need self-hosting, custom code or volume. We work with all three, and recommend the one that fits your context, not our habits.

What we do

Our n8n services, from audit to production.

Audit & design

We map your processes, identify what is worth automating, and specify each workflow: connected tools, guardrails, error cases.

Workflow development

Automations built in your environment, with custom code where standard nodes stop being enough. A demo every week.

Self-hosting & managed ops

Your n8n instance installed on your servers or a dedicated EU server: hardening, backups, version upgrades, monitoring.

AI agents in your workflows

E-mail triage, lead qualification, document extraction: we integrate AI models directly into your n8n workflows, under human supervision.

Takeover of existing workflows

Workflows built in-house or by a previous provider: audit, hardening (error handling, alerts), documentation, evolutions.

n8n training

Hands-on onboarding of the tool and of the deployed workflows, so your teams can drive (and evolve) their automations without us.

Pricing

How much does an n8n workflow cost? Our ranges.

The same public ranges as on our general pricing grid, because a provider that hides its prices wastes your time.

Price ranges for Merlin's n8n services
30-min diagnosticFree
Process auditfrom €1,500
First n8n automation€1,500 – €8,000
n8n training (on-site)€1,000 / day
Managed ops & supportfrom €300 / month

Indicative ranges: every project is quoted after the audit. What makes the price vary: the number of connected tools, the volume, how critical the process is, the hosting.

Fixed quote after the audit: no time-and-materials billing, no surprises.

Method

From audit to a running workflow, in four steps.

  1. Audit : we map your processes and cost the 2-3 most profitable automations. The plan is yours, whether you continue with us or not.
  2. Design : each workflow is specified: connected tools, triggers, error handling, human supervision.
  3. Deployment : built in your environment (Cloud or self-hosted), tested on your real data, nothing in production without your approval.
  4. Production : monitoring, alerts, fixes, evolutions. A monthly review of time recovered and next candidates.

n8n automations built by Merlin run in production today for Acuity, Voilà and BindeX : user feedback processing, business workflows, automated triage and replies.

FAQ

Your questions about n8n: pricing, hosting, migration.

What is n8n?

n8n is an open-source workflow automation tool: it connects your applications (CRM, e-mail, spreadsheets, ERP) through hundreds of integrations, and lets you plug AI models into a process. Its defining trait: it can run on your own servers.

Is n8n free?

The self-hosted software has no license fee for most internal uses; n8n Cloud, the vendor-hosted version, is a paid subscription. What you pay an agency like Merlin for is workflow design, hardening and maintenance, not the software.

n8n, Make or Zapier: which one should we pick?

Make and Zapier are quicker to learn but only exist as SaaS. n8n wins as soon as you need self-hosting (GDPR, sensitive data), custom code or volume: its cost does not grow with every execution. We work with all three and recommend based on your context, not our habits.

Can n8n run on our own servers?

Yes. That is often the main reason to choose n8n: your instance runs on your infrastructure or on a dedicated EU server, and your data never passes through a third-party SaaS. We install, secure, update and monitor the instance.

How much does an n8n workflow cost?

A first n8n automation runs between €1,500 and €8,000 depending on the number of connected tools and how critical the process is. Production support starts at €300 per month. Our ranges are published in the Pricing section; every project is quoted as a fixed price after the audit.

Do you take over existing n8n workflows?

Yes. We audit what exists, harden what needs it (error handling, alerts, logging), then document and evolve your workflows, including those built in-house or by a previous provider.
