n8n workflow: a new lead is checked by AI, approved by a person, added to the CRM and posted to Slack

You have a list of boring, repeated jobs: copying leads into the CRM, chasing unpaid invoices, sorting support emails, sending the same weekly report. n8n can automate most of them, and with AI steps it can also read emails, summarise documents and draft replies. The question is who builds it. This guide explains what an n8n developer does, when a freelancer, an agency or a dedicated engineer is the better choice, what it costs, and the questions to ask before you hire.

What is n8n, in one paragraph?

n8n is a workflow automation tool: you connect apps (Gmail, HubSpot, QuickBooks, Slack, Telegram, your own database or API) with steps such as "when a form is sent, check the company, add it to the CRM and tell the sales team". Unlike Zapier or Make, n8n can be self-hosted on your own server, so your data stays with you and you do not pay per task. It also has built-in AI nodes for models such as OpenAI, Claude or local models. See our comparison of self-hosted n8n, Zapier and Make.

What does an n8n developer do?

  • Maps the process first: who does what today, where the data comes from, what can go wrong.
  • Builds the workflows: triggers, app connections, data clean-up, branches and error paths.
  • Adds AI where it helps: reading emails and PDFs, classifying tickets, drafting replies, with a person approving anything risky.
  • Writes custom code when needed: JavaScript or Python steps, custom API calls, and webhooks for systems that have no ready-made node.
  • Hosts and secures n8n: Docker, backups, HTTPS, user access, stored credentials and updates.
  • Monitors it: alerts when a workflow fails, logs, and retries, so automations do not break silently.

Freelancer, agency or dedicated engineer?

A simple rule: if you can describe the whole job in one sentence, a freelancer may be enough. If the workflows touch customer data, money or several systems, choose a team that also handles hosting, security and monitoring.

How much does it cost to hire an n8n developer?

Cost depends on the number of workflows, how many systems they touch, and whether AI steps and approvals are involved. The main pricing models are:

  • Per hour: common for freelancers; good for small fixes.
  • Fixed price per workflow or project: good when the process is clear and documented.
  • Dedicated engineer: one person working full time on your automations. At UnlockLive this starts from $750 per week per full-time engineer, paid week by week with two weeks' notice.

Do not forget running costs: a small server for self-hosted n8n, and AI model usage if workflows call an AI model. Self-hosting usually costs far less than per-task pricing once you run thousands of tasks a month.

10 questions to ask before you hire

  1. Can you show a workflow you built that is running in production today?
  2. Will n8n run on our server or cloud account, and who owns the workflows and credentials?
  3. How do you handle errors: alerts, retries, and what happens to the data?
  4. How do you store API keys and passwords?
  5. Where do AI steps need a human to approve before anything is sent or changed?
  6. How do you test a workflow before it touches real customers?
  7. Can you write custom code or API connections when there is no ready-made node?
  8. Who updates n8n and fixes things when an app changes its API?
  9. Will you document each workflow so our team understands it?
  10. What happens if we stop working together?

Good first workflows to automate

  • Lead follow-up: a new form or email lead is checked, added to the CRM and answered within minutes. See lead follow-up with n8n and Telegram.
  • Invoices: supplier invoices are read by AI and prepared in your accounting tool for approval. See AI document extraction.
  • Support triage: incoming tickets are sorted by urgency and topic and sent to the right person.
  • Reports: a daily or weekly summary of key numbers posted to Slack or Telegram.

Red flags

  • Everything runs on the developer's personal account.
  • No error alerts: you find out a workflow broke when a customer complains.
  • AI sends emails or changes records with no approval step and no log.
  • No documentation, so only one person understands the system.

We can also connect n8n to AI agents and MCP servers; see AI agents with n8n, MCP and human approval. Tell us which process you want to automate and we will reply with honest next steps.

Frequently asked questions

What does an n8n developer do?

An n8n developer maps your process, builds automated workflows that connect your apps, adds AI steps where they help, writes custom code for systems without ready-made connections, and hosts, secures and monitors n8n so the workflows keep running.

How much does it cost to hire an n8n developer?

It depends on the number of workflows and systems involved. Freelancers usually charge per hour, agencies often quote a fixed price per project, and dedicated engineers are paid per week or month. At UnlockLive a dedicated full-time engineer starts from $750 per week.

Should I hire an n8n freelancer or an agency?

A freelancer can be enough for one small, clear workflow. For workflows that touch customer data, money or several systems, choose a team that also handles hosting, security, monitoring and documentation.

Is self-hosted n8n secure?

It can be, when it runs behind HTTPS with strong user access, encrypted credentials, regular updates and backups. Self-hosting also keeps your data on your own server instead of a third-party automation platform.

Can n8n use AI models like ChatGPT or Claude?

Yes. n8n has AI nodes for models such as OpenAI and Anthropic Claude, and it can also call local models. Use AI for reading, sorting and drafting, and keep a human approval step for anything sent to customers or changes to important records.
