For a Microsoft 365 team, Power Automate is usually the better first choice when the work happens in Outlook, SharePoint, Teams, Excel and Forms, because those connectors are standard and already covered by the Microsoft 365 licence. Zapier is the stronger choice when the automations connect many apps outside Microsoft's ecosystem and you prefer a bill based on task volume. Many teams use both, and the sections below show where each one fits and what it costs.
Who this is for and what you will have
This guide is for IT leads and operations owners at businesses on Microsoft 365 who have to pick, or justify, an automation platform. It goes beyond the price per task and compares connectors, sharing, AI features, desktop automation and cost when several people build automations. A shorter pricing-only view is in Zapier vs Power Automate: Pricing and Fit for a Small Business. By the end you will have a checklist you can apply to your own first three automations.
All prices are US dollar list prices from the vendor pages at the time of writing and can change, so confirm them before you buy.
The core difference in one table
| Question | Power Automate | Zapier |
|---|---|---|
| Unit of billing | Licence per user, or per flow or bot | Monthly task allowance |
| What counts as usage | Actions per day under a licence limit | Successful action steps |
| Microsoft 365 apps | Standard connectors, covered by Microsoft 365 licences | Available as app integrations. Check the app directory for the actions you need |
| Entry price | Included with Microsoft 365 for standard connectors | Free plan with 100 tasks per month |
| Apps with no API | Desktop flows (robotic process automation) | Not an RPA tool. Use integrations, webhooks or code |
| Identity and tenant controls | Part of the Microsoft 365 tenant | Separate Zapier account and connections |
Connectors: what is included
Microsoft publishes the list of standard connectors, and it includes the ones most Microsoft 365 teams start with: Office 365 Outlook, SharePoint, Microsoft Teams, Excel Online (Business), OneDrive for Business, Planner and Microsoft Forms. A Microsoft 365 licence, and the Power Automate Free licence for work or school accounts, entitle users to create and run cloud flows with standard connectors. The Free licence does not allow sharing flows.
Premium connectors and custom connectors need a Power Automate Premium user licence, or a Process licence assigned to the flow. Microsoft documents that a Process licence assigned to a cloud flow gives it higher action limits and lets it use premium and custom connectors regardless of the licence of the owner or the user who triggers it. Flows must be in a solution for a Process licence to be assigned. For the details, see Power Automate Licensing: Premium Connectors Explained.
Zapier's model has no standard or premium split by connector for paid plans. Its Professional plan includes unlimited premium apps, while the Free plan has no premium apps or webhooks. For any app, check Zapier's app directory for the exact triggers and actions you need before you commit, because the existence of an app is not the same as support for your specific action.
Team features
A team needs shared ownership, central control and a record of changes. The vendors approach this differently.
Power Automate
Cloud flows run under a licence context. A Premium licence lets a user create, run and share unlimited cloud flows within action limits, and a Process licence lets a flow be maintained without every co-owner needing a user licence. Microsoft's licence documentation recommends Premium for all users who need the full set of capabilities, and notes that capacity licences do not replace user licences in an environment. Because Power Automate sits inside the Microsoft 365 tenant, administrators govern it with the same tenant tooling as the rest of Microsoft 365.
Zapier
Zapier's free and Professional plans are single-seat accounts. The Team plan, listed from 69 USD per month billed annually at 2,000 tasks, includes everything in Professional plus 25 seats, shared Zaps, folders and app connections, SAML SSO, a six-month audit log, priority support and six-month version history. Enterprise adds unlimited seats, SCIM provisioning, custom data retention, analytics, managed app connections and a technical account manager, with custom pricing through sales.
If several people will own automations, the Zapier Team plan is the first tier that fits that need, because shared connections avoid a single person's account being the connection behind a business process. In Power Automate the equivalent concern is solved with solutions, Process licences and co-owners.
AI features
Both products have an AI assistant for building automations and AI steps that run inside them.
| Capability | Power Automate | Zapier |
|---|---|---|
| Build with natural language | Copilot in cloud flows: describe the flow, review the suggested trigger and actions, and connect accounts | Copilot, with a daily limit on the Free plan |
| AI inside the automation | AI Builder, using service credits. Premium and Process licences include 5,000 credits per month | AI by Zapier, available on Professional and above. Usage depends on the model tier you select |
| Agents | Not covered in the pages used for this article | Zapier Agents, which use a separate activity quota rather than tasks |
| Other | Troubleshoot in Copilot for failed runs | MCP access, where each successful tool call uses 2 tasks |
Microsoft notes that Copilot in cloud flows is optimized for English and has limited support in other languages, is powered by Azure OpenAI Service, and is available in the new designer only. Its documentation recommends prompts in the form "When X happens, do Y" and naming the connector, for example "When an email arrives, post the subject to the General channel in Teams". For a guided example of AI in a mailbox workflow, see Automate Shared Mailbox Triage with Power Automate and AI Prompts.
Desktop and legacy applications
If part of your process lives in a Windows application with no API, Power Automate has a capability Zapier does not: desktop flows, which use robotic process automation to simulate keyboard and mouse actions. Microsoft's licence page explains the split. Premium includes one attended bot for the registered workstation of the user. Unattended runs need a Process licence allocated to a machine, which becomes an unattended bot that runs one desktop flow at a time, and the machine must have been registered by a Premium user. See Power Automate Desktop: Getting Started with RPA if this is a requirement.
Limits you should plan around
| Item | Power Automate | Zapier |
|---|---|---|
| How limits are expressed | Daily action limits. Premium is 40,000 per user per 24 hours and Process is 250,000 per licence, in Microsoft's table | Monthly task allowance by plan, from 100 on Free up to 2 million |
| Counting rule | Actions count whether they succeed or fail | A successful action step uses 1 task. Triggers, filters and paths, and steps that error or halt do not |
| Polling interval | Depends on the trigger | Free plan polls every 15 minutes. Professional lists 2-minute polling |
Microsoft documents a transition period in which cloud flows have higher per-flow limits. Plan around the per-user numbers that apply afterwards. On the Zapier side, task usage has a few special cases: each successful tool call through MCP uses 2 tasks, and Zapier Agents use a separate activity quota.
What it costs for a team
Use these list prices to build a quick estimate. They are from the vendors' pages, and Microsoft notes that pricing on its page is for marketing purposes and can differ at checkout.
| Option | List price (USD, annual billing) | What you get |
|---|---|---|
| Microsoft 365 licence | Already owned | Cloud flows with standard connectors |
| Power Automate Premium | 15 per user per month | Premium and custom connectors, attended desktop flows, 5,000 AI Builder credits per month |
| Power Automate Process | 150 per bot per month | Per-flow licence with premium connectors, higher limits and an unattended bot |
| Zapier Free | 0 | 100 tasks, two-step Zaps, one seat |
| Zapier Professional | From 19.99 per month at 750 tasks, 49 at 2,000 | Multi-step Zaps, premium apps, webhooks, AI by Zapier |
| Zapier Team | From 69 per month at 2,000 tasks, 119 at 5,000 | 25 seats, shared connections, SSO, audit log, version history |
Worked examples, using only these list prices:
- Ten people automating Outlook and SharePoint tasks with standard connectors: nothing beyond Microsoft 365 in Power Automate.
- Six people who each need a premium connector: 6 x 15 = 90 USD per month in Power Automate Premium.
- One company-wide flow with a premium connector that many people trigger: one Process licence at 150 USD per month, versus licensing everyone who owns it.
- A team that wants shared Zapier connections, SSO and an audit log at 2,000 tasks: from 69 USD per month on the Team plan, billed annually.
A decision procedure
- List your first three automations with the apps, the trigger and the owner.
- Check each app's connector class in Microsoft's connector reference and each action in Zapier's app directory.
- If every step is a standard Microsoft 365 connector, build it in Power Automate under existing licences.
- If a step needs an app that only Zapier connects well, price a Zapier plan from the monthly successful action steps you expect.
- If you need a Windows desktop app, plan Power Automate desktop flows and the licence they require.
- If more than one person will own a business-critical automation, decide who holds the connections: Zapier shared connections on the Team plan, or Power Automate solutions and a Process licence.
- Pilot for a month and review failures in run history before moving more work over.
Using both without conflict
Nothing prevents you from running Power Automate for Microsoft 365 work and Zapier for other apps. Avoid two automations acting on the same record, record every automation with an owner and the connections it uses, and remove a leaver's connections. Review run history regularly. For failure handling in Power Automate see Power Automate Error Handling with Try-Catch Scopes.
