Power Automate beats Zapier when you already pay for Microsoft 365 and your automations stay inside Microsoft apps such as Outlook, Teams, SharePoint and Excel. Those standard connectors cost nothing extra, up to 6,000 actions a day per user. Zapier wins once your key apps sit outside Microsoft, because most popular small-business connectors are premium in Power Automate.
The pricing models are different, and that changes the maths. Zapier charges per task, so cost grows with volume. Power Automate charges per user (or per process), so one $15-a-month Premium licence for the person who owns your flows can undercut Zapier at high volume. The catch is effort: Power Automate takes longer to learn, and its connectors for many third-party apps are community-built and thinner than Zapier's.
Side by side on the points that decide it
| What matters | Power Automate | Zapier |
|---|---|---|
| What you may already pay for | Included with Microsoft 365 business plans, standard connectors only | Nothing; free tier is 100 tasks a month, two-step Zaps |
| Pricing model | Per user; Premium $15/user/month (annual), Process $150 per bot a month | Per task; Professional from $29.99/month (750 tasks), $19.99 billed annually |
| Microsoft apps | Deepest available: SharePoint lists, Teams, Planner, Excel Online, Approvals | Good coverage, fewer triggers and actions |
| Non-Microsoft apps | Many are premium, often Independent Publisher connectors | Thousands of apps, usually built with the vendor |
| Human approvals | Approvals connector, standard, included | Human in the Loop, Professional and above |
| AI steps | AI prompts consume credits (moving to Copilot Credits) | AI by Zapier: 1, 3 or 5 tasks per run by tier |
| Ease of building | Steeper; expressions and licensing rules to learn | Quicker for non-technical staff |
| Limits to know | 6,000 actions/day per Microsoft 365 user; runs time out at 30 days | Task allowance per month; polling every 2 minutes on Professional |
| Desktop automation | Yes (desktop flows), licensing applies | No |
What your Microsoft 365 licence already includes
If your team is on a Microsoft 365 business plan, each licensed user can already create and run cloud flows (automated, scheduled and button-started) that use standard connectors. According to Microsoft's licensing FAQ, that allowance is 6,000 actions per user per day, and every trigger and action counts, including simple built-in ones like setting a variable. For a small business that's a lot of headroom: a flow with ten actions running 200 times a day uses 2,000.
The standard set covers most of what a Microsoft-based business does internally:
- Outlook: save attachments, file emails, send notifications and summaries.
- SharePoint and OneDrive: create list items, move files, react to new documents.
- Teams: post messages and adaptive cards to channels or people.
- Excel Online (Business): add rows to tables, read tables for reports.
- Forms: trigger on new responses.
- Approvals: send approval requests with Approve and Reject buttons, including sequential and "everyone must approve" options.
Several common non-Microsoft apps are standard too, including Gmail, Slack, Trello and Asana. And Windows 11 users can try desktop flows, which record and replay actions in desktop software, for their own use in the default environment. Sharing those or running them from cloud flows needs Premium.
For an illustrative sign maker with eight staff on Microsoft 365, that meant four useful flows at no extra cost: a Forms quote request that creates a SharePoint list item and posts to the sales channel in Teams; a production sign-off using Approvals; a Friday email summarising the week's jobs from an Excel table; and supplier invoices saved from Outlook into the right SharePoint folder.
The premium-connector line, and why it decides most cases
Microsoft splits connectors into standard and premium. Users on Microsoft 365 licences can only use standard ones. The problem for small businesses is where the line falls. Checking Microsoft's connector reference in September 2026, these popular connectors are premium:
- CRM and sales: Salesforce, HubSpot, Pipedrive
- E-commerce and payments: Shopify, WooCommerce, Stripe
- Marketing: Mailchimp
- Support: Zendesk
- Databases and tools: Airtable, Notion, monday.com, SQL Server, and the HTTP action for calling any web service
- Scheduling and accounts: Calendly, FreshBooks
- AI: OpenAI, Azure OpenAI, Google Gemini and Anthropic connectors
There's a second thing to check on each connector page: who built it. Many third-party connectors, including the Shopify and HubSpot CRM ones, are labelled Independent Publisher, meaning a community developer built and maintains them rather than the software vendor. They're certified by Microsoft and often work well, but they can have fewer triggers and slower fixes when the vendor changes its system. Zapier's integrations for the same apps are typically broader. So if your automations are built around a CRM, a shop or a payment platform, you'd be paying for Premium and getting a thinner connector.
The quick test: list the apps in each automation you want. If every one is Microsoft or on the standard list, Power Automate is probably your answer. If one key app is premium, go on to the licence maths below.
Checking a connector in five minutes
Before you commit to either tool for an automation, do this for each app involved:
- Find the app's page in Microsoft Learn's connector reference. The availability table shows whether it's Standard or Premium for Power Automate, and the page header shows the publisher.
- Read the list of triggers. The trigger is the event that starts your flow, such as "when a new order is created". If the one you need isn't there, the flow can't start the way you want.
- Open the same app's page on Zapier and compare its triggers and actions.
- Note any gap against the automation you have in mind.
The software reseller in the scenarios below found its answer at step 2. One of its automations starts when a renewal payment fails. Power Automate's Stripe connector offers triggers for new charges, customers, invoice items and orders, but not for failed payments. That took four minutes to discover on paper and would have taken an afternoon to discover by building.
How the licences work when you do need Premium
This is where Power Automate is often cheaper than people expect, and where it trips people up. The rules that matter for small businesses, from Microsoft's licensing FAQ:
- Automated and scheduled flows run as the flow's owner. If such a flow uses a premium connector, only the owner needs Premium. One $15-a-month licence can cover a whole set of background flows.
- Button-started (instant) flows run as the person who starts them. If an instant flow uses a premium connector, everyone who runs it needs Premium, or you license the flow itself with a Process licence ($150 a month).
- Premium users get 40,000 actions a day instead of 6,000.
- Unattended desktop automation, on a machine with nobody logged in, needs a Process licence per machine.
Put together: a small business whose automations are mostly background flows can often license a single owner and stop there. Don't try to get around the per-user rules by routing many people's requests through one account; Microsoft's guidance treats that kind of "multiplexing" as a licensing breach.
AI inside each tool
Both tools can put an AI step inside a workflow, and both charge for it differently from normal steps.
In Power Automate, AI prompts (and other AI Builder features such as document processing) consume credits. Microsoft is ending AI Builder credits in stages: new customers could no longer buy AI Builder capacity add-ons from 1 November 2025, and from 1 November 2026 new and renewed premium licences stop including seeded AI Builder credits. The replacement is Copilot Credits, bought separately. Existing credits are honoured to the end of your contract term. So if you plan AI steps in Power Automate, budget for Copilot Credits rather than assuming a Premium licence covers them. Power Automate's designer also has Copilot built in to draft a flow from a plain-English description, which helps with the learning curve.
In Zapier, AI by Zapier steps cost one, three or five tasks per run depending on the model tier, or one task with your own API key. It's simpler to predict, and adding AI steps to Zapier works through the task maths for classify, summarise and draft steps. For both platforms, the per-run AI cost is small next to the licence decision.
Which platform wins for three different software stacks
The sign maker, all Microsoft. Eight users on Microsoft 365 Business Standard. The four flows above plus a fifth, a daily Teams post listing jobs due for installation, all use standard connectors. Illustrative volume: about 1,800 actions on a busy day, spread across two flow owners. Extra cost in Power Automate: $0. The same five automations in Zapier would need a paid plan: at around 1,500 tasks a month they'd exceed the 750-task entry tier. Power Automate wins clearly.
A translation agency on Google Workspace, HubSpot and online accounting. Its key automations move enquiries from HubSpot into project folders, chase unpaid invoices and notify project managers in Slack. HubSpot is a premium Independent Publisher connector in Power Automate, and the agency has no Microsoft 365 licences at all. Zapier wins: better HubSpot integration, no Microsoft licences to buy and a gentler learning curve for the operations manager who'll build it.
A software reseller with Microsoft 365, Shopify and Stripe. This is the close call. It runs about 6,000 Zap tasks a month syncing orders, licence renewals and payments, which puts it on a mid-level Zapier tier. In Power Automate, all its flows are automated or scheduled, so one flow owner on Premium ($15 a month, annual) would cover the premium connectors with a 40,000-actions-a-day allowance. On licence cost alone Power Automate is far cheaper. But the Shopify connector is community-built with fewer triggers, its failed-payment Zap has no matching trigger in the Power Automate Stripe connector, and nobody on the team knows Power Automate. The reseller's decision: move the Microsoft-only automations (renewal reminders from SharePoint, Teams alerts) to Power Automate, keep the Shopify and Stripe Zaps in Zapier, and drop to a smaller Zapier tier. That split saved money without rebuilding anything fragile. If Zapier costs are the main worry, finding Zapier's tipping point sets out other ways to cut them.
Where Power Automate is harder than it looks
- Learning curve. Beyond simple flows you'll meet expressions (a formula language for dates, text and conditions) and JSON. Zapier hides most of that.
- Flow ownership. Automated flows run under the owner's account and licence. When that person leaves and their account is removed, their flows stop. Add a co-owner to every important flow, and consider a dedicated automation account, licensed properly.
- Run time limit. A single flow run lasts at most 30 days, and pending steps such as approvals time out then. An approval that sits unanswered for a month simply fails.
- Connector throttling. Separate from the daily allowance, connectors have per-minute limits; SharePoint's is 600 actions a minute per connection. Bulk jobs can hit it.
- Automatic switch-offs. Microsoft turns off a cloud flow whose trigger or actions fail continuously for 14 days, and a flow that isn't triggered for 90 days may be turned off too (owners get 30 days' notice; flows owned by Premium users are exempt). A quarterly or annual reminder flow on a Microsoft 365 licence is exactly the kind that gets caught.
- Error visibility. Failed runs show in the flow's run history and the owner gets the notices, but nobody else sees them unless you build notifications in.
- Admin policies. Your Microsoft 365 administrator can restrict which connectors may be combined. That's good governance, and a surprise if you build a flow before checking.
None of these is a reason to avoid Power Automate. They're reasons to have one person own automation properly, whichever tool you use.
A worked choice: the sign maker's automation list
Here's how the illustrative sign maker sorted its full wish list after reading the connector pages:
| Automation | Apps involved | Connector tiers | Decision |
|---|---|---|---|
| Quote request to SharePoint list and Teams | Forms, SharePoint, Teams | All standard | Power Automate |
| Production sign-off before cutting vinyl | SharePoint, Approvals | All standard | Power Automate |
| Weekly jobs summary email | Excel Online, Outlook | All standard | Power Automate |
| Supplier invoices filed from email | Outlook, SharePoint | All standard | Power Automate |
| New web-shop orders into the job list | WooCommerce, SharePoint | WooCommerce premium | Zapier (low volume, keeps licence cost at zero) |
| Review request after installation | SharePoint, review platform | No Power Automate connector for the review platform | Zapier |
That gave four automations in Power Automate at no extra cost and two in Zapier at about 150 tasks a month. That's over the free tier's 100 tasks, and the web-shop Zap needs three steps where the free plan allows two, so the sign maker took Zapier's entry Professional tier for the pair. The alternative, Premium for one flow owner at $15 a month, would have covered WooCommerce but not the review platform.
Running both without making a mess
Plenty of small businesses end up with both, which is fine if you keep track. Three habits help:
- One register. A single list of every flow and Zap: what it does, which tool, who owns it, what breaks if it stops. The method in auditing automations nobody owns applies to Power Automate flows just as well.
- A rule for new builds. "Microsoft-only goes in Power Automate; anything with a premium connector goes in Zapier unless we've licensed an owner" stops every new automation becoming a debate.
- Errors in one place. Route failure alerts from both tools to the same channel or inbox, so one person sees everything.
Where approvals are involved, Power Automate's Approvals connector is one of its strongest points for Microsoft businesses, and a good reason to put sign-off steps there even if other automations live in Zapier. Adding human approval steps to AI automations compares how each tool handles them. And before building either, check whether the two apps already talk to each other directly; native integrations versus Zapier explains when the built-in connection is the cheaper, sturdier option.
Power Automate questions from Zapier users
Is Power Automate free with Microsoft 365?
Partly. Microsoft 365 business licences let each user build and run cloud flows that use standard connectors, such as Outlook, SharePoint, Teams, Excel Online, Forms and Approvals, at no extra cost, up to 6,000 actions a day per user. Premium connectors, custom connectors and attended desktop automation need a Power Automate Premium licence, listed at $15 per user a month on annual billing.
Can Power Automate connect to Gmail and Slack?
Yes. Gmail, Slack, Trello and Asana are standard connectors, so a Microsoft 365 licence covers them. The line falls elsewhere: Salesforce, HubSpot, Shopify, Mailchimp, Stripe, Zendesk, Airtable and the generic HTTP action are premium. Check any connector's page on Microsoft Learn, which shows whether it's Standard or Premium, before you plan a flow around it.
Can I import my Zaps into Power Automate?
No. There's no import between the two, so moving means rebuilding each automation. That's usually a good moment to simplify: list what each Zap does, drop the ones nobody relies on, and rebuild the rest one at a time, running old and new side by side for a week before switching the Zap off.
What is Power Automate for desktop?
It's the tool for recording and replaying clicks and keystrokes in desktop applications, known as robotic process automation. Windows 11 users can try desktop flows for their own use in the default environment. Sharing them, running them from cloud flows and other premium features need a Premium licence, and unattended runs on a machine with nobody present need a Process licence.
