n8n vs Power Automate: Which to Choose If You Use Microsoft 365

If your company already pays for Microsoft 365, the question sounds rhetorical: why look anywhere else when Power Automate "already comes included"? The short answer to n8n vs Power Automate: Power Automate wins inside the Microsoft ecosystem (Teams, SharePoint, Outlook), but its per-user licensing and premium connectors drive up the cost of everything that leaves that world; n8n costs the same with 2 users or 200 and connects to any API, so for most mid-sized companies the optimal play is hybrid, not either-or. Let's see why, with numbers.

The "I already have it included" that isn't quite true

The most expensive misunderstanding in the Microsoft world: Microsoft 365 licenses do include Power Automate, yes, but only with standard connectors. The catalog splits in two:

• Standard connectors (included): Outlook, Teams, SharePoint, OneDrive, Forms, Planner. Everything that lives inside Office.
• Premium connectors (paid separately): SQL Server, Salesforce, DocuSign, Adobe Sign, Azure Functions, and several capabilities of the HTTP connector. In other words: almost anything that touches a system outside Microsoft.

The moment a flow uses a premium connector, every user who runs it needs a Power Automate Premium license: USD 15 per user per month. For unattended flows (those that run on their own, with no user) there are per-flow plans starting at USD 100-150/month per bot/process depending on the model. That's where "included" turns into a new budget line — and because the need for premium connectors only shows up once flows mature, the cost arrives after you already depend on the platform, which is the worst possible moment to negotiate.

Per-user license vs. single instance: the math

This is the structural difference. Power Automate charges per person; self-hosted n8n charges per server.

Scenario	Power Automate	n8n self-hosted
3 users with premium flows	USD 540/year	USD 120-300/year (VPS)
10 users with premium flows	USD 1,800/year	USD 120-300/year
25 users + 2 unattended flows	USD 6,900-8,100/year	USD 300-600/year
Standard flows inside Office only	USD 0 extra	Doesn't compete: stay on PA

The last row matters, and most comparisons hide it: if your automations live 100% inside Microsoft 365 with standard connectors, Power Automate effectively costs you nothing extra and n8n has no case.

The problem is that almost no real company lives 100% inside: the on-prem ERP, Mercado Pago, WhatsApp, the logistics provider's API, the AI model — all of that is premium territory in Power Automate and natural territory for n8n. We've dedicated a whole article to the full costs of an implementation: how much it costs to implement n8n in a company.

Technical capability: where each one wins

Power Automate wins on:

• Native Office integration: triggering a flow when an email lands in a shared mailbox, approvals with buttons inside Teams, manipulating SharePoint lists. Nothing does it as smoothly.
• Corporate governance: DLP policies, Azure AD permissions, centralized auditing in the tenant. For the IT department of a 200+ employee company, this carries weight.
• End-user adoption: someone in HR can build their own approval flow without asking anyone for permission.

n8n wins on:

• Everything that isn't Microsoft: 400+ integrations with no "premium" distinction, plus the HTTP Request node for any API on the planet — including local LATAM systems Microsoft doesn't even know exist.
• Complex logic: embedded JavaScript/Python code, reusable sub-workflows, fine-grained error handling. Power Automate's expressions become unreadable far sooner.
• AI and agents: native nodes for language models, memory and tools. It's the foundation of our AI integration projects; in Power Automate, AI runs through AI Builder, which is billed by credits and performs worse for custom cases.
• Data on your own server: self-hosted n8n sends nothing to a third-party cloud, a decisive argument in finance and healthcare.

Vendor lock-in: the cost that doesn't show up on the invoice

Every flow you build in Power Automate deepens your dependence on Microsoft: flows don't export to any standard, the licenses change name and price every couple of years (it happened with the "per flow" plans), and migrating 50 flows to another platform means rewriting them from scratch.

n8n, being open source, gives you an exit Power Automate doesn't: if n8n GmbH disappears tomorrow or changes its license, your instance keeps running on your server with the version you have. The workflows are exportable, Git-versionable JSON. It's not zero lock-in — rewriting always costs — but the risk floor is different.

The hybrid setup almost nobody covers (and almost always wins)

The decision isn't binary, and here's the approach we apply at mid-sized companies running Microsoft 365:

Power Automate keeps the internal-Office work:

• Expense and vacation approvals in Teams.
• Flows over SharePoint lists and Outlook alerts.
• Personal automations each employee builds with standard connectors.

n8n takes the external and the heavy:

• Integrations with the ERP, Mercado Pago, WhatsApp Business and provider APIs.
• High-volume unattended processes (stock sync, reconciliations, reports) that would cost a per-flow plan in PA.
• Anything involving AI: email classification, agents that query systems, data extraction from documents.

The bridge between the two is trivial: Power Automate has an HTTP trigger and action, and n8n runs on webhooks. A PA flow that detects an email with an invoice can fire a webhook to n8n, which processes it with AI, loads it into the ERP and returns the result to a SharePoint list. Each platform does what it does best, and premium licenses shrink to the 2-3 users who actually need them.

Typical result of this redesign at a 30-60 employee company: from 12-15 premium licenses down to 3-4, savings of USD 1,500-2,500/year, plus new technical capability (WhatsApp, AI, local APIs) they simply didn't have before. Implementing this setup is a 3-6 week AI automation project.

When you should NOT bring in n8n

To keep ourselves honest:

• 100% Microsoft company with simple flows: if everything is Office and standard connectors, n8n just adds another system to maintain with no clear benefit. Stay on PA.
• Restrictive IT with no appetite for self-hosting: if your corporate policy forbids servers outside the approved standard, the bureaucratic fight can cost more than the licenses. (n8n Cloud may be the middle ground.)
• No technical person or partner: a self-hosted instance with no owner degrades. Power Automate, with all its costs, is maintained by Microsoft.
• Desktop RPA automation: to record clicks over legacy Windows applications, Power Automate Desktop is the tool; n8n doesn't do UI RPA.

If, beyond Power Automate, you're also weighing other platforms on cost, we break down the "operations vs. executions" logic in n8n vs Make.

The decision in one sentence

Stay on Power Automate for what happens inside Office; add n8n when your automations need to reach the real world — ERPs, WhatsApp, payments, AI — without multiplying licenses per user.

At Deepyze we design and implement this hybrid setup for companies across LATAM: we audit your current flows, stand up the n8n instance, build the integrations (including API development when your systems don't expose data) and leave everything monitored. Fixed price, a proposal within 24 hours, and a team in your time zone that understands how things work here. Tell us what you've got running today and we'll tell you exactly what to keep, what to move, and how much you'll save.
