Zapier is a genuinely good product — this is not an argument that it is bad. It is an argument that if you are on Microsoft 365 Business Standard or Premium, you are very likely paying for the engine that runs the same automations, sitting unused inside a licence you bought months ago. And there is a second cost that never shows up on an invoice: every time you connect your accounting system or your customer data to a third-party automation platform, that data leaves your business and passes through someone else's cloud — usually offshore.
For a lot of small businesses there is a better option they have never been told about: run the automation inside the tenant you already own, on the licence you already pay for, with the data never leaving your environment. Here is how that works — and, just as importantly, where it does not, so you can tell which side of the line your business sits on.
What you are probably already paying for
Microsoft 365 is not just email and Word. On most Business plans, three tools ship inside your subscription that together cover the majority of what a small business asks Zapier to do:
Power Automate
Microsoft’s workflow engine — the direct equivalent of Zapier’s “when this happens, do that.” Core flows are included in Microsoft 365 Business plans. It is what moves an invoice from your inbox into Xero, chases an overdue payment, or routes an approval to the right person, without you touching it.
AI Builder
The document-reading layer. It is what reads an invoice PDF and pulls out the supplier, ABN, amount, and GST without a human retyping it — the piece doing the heavy lifting behind proper invoice automation.
Power BI Pro
Included in Microsoft 365 Business Standard and above. The reporting and dashboard layer — the thing that turns data scattered across your systems into one live view.
If you are on Business Standard or Premium, the core of all three is already in your bill. For a five-to-twenty person business, that often covers the automations that matter most — invoice processing, payment chasing, compliance reminders, approvals, reporting — without a single new subscription.
The honest caveat, up front: “core” is doing real work in that sentence. Some advanced connectors and higher-volume AI Builder usage sit outside the base licence and carry an add-on cost. Which of your specific automations fall inside your existing licence and which need a top-up is exactly the kind of thing worth confirming before you commit to anything. The point is not “it is all free” — it is that you may be paying Zapier for something your Microsoft licence already substantially covers.
The part nobody selling you automation wants to mention: where your data goes
Set licensing aside for a moment, because the bigger issue is data. When you automate with Zapier, Make, or n8n, your information flows through their platform to get from one app to another. Your invoices, your customer records, your financial data — it leaves your business, transits a third-party service, and in almost every case sits on infrastructure outside Australia. That is not a scandal; it is just how those platforms are built. But it is a decision you are making, often without realising it, and it is worth making on purpose.
Running the same automation inside your own Microsoft 365 tenant changes the picture:
Your data stays in your environment
The automation runs where your data already lives. It is not copied out to a third-party platform to be processed.
You can keep it data-resident in Australia
Microsoft 365 tenants can be configured so your data is hosted on infrastructure physically located in Australia.
The security model is tighter
Access is least-privilege and read-only where it can be. Every action is logged. No financial credentials are handed to an outside service, and your data is not used to train anyone’s public AI models.
One point of precision, because it matters and because most people get it wrong: data hosted in Australia is data residency, not sovereignty. Microsoft is a US-headquartered company, so the US CLOUD Act can still apply even to data stored here. For most small businesses, residency inside your own tenant is a genuine and meaningful step up from routing data through an offshore automation platform. If you have strict sovereignty obligations, that is a more specialised conversation — and the fact that most providers blur this line is exactly why it is worth being clear about.
When Zapier genuinely is the right answer
This is not an argument that nobody should use Zapier. There are real cases where a third-party platform is the better call, and pretending otherwise would just be a sales pitch:
You are not on Microsoft 365 — you run on Google Workspace, or a mix of standalone tools with no shared platform.
You need to connect niche apps that only have off-the-shelf Zapier or Make integrations and no practical path through Power Automate.
Your automations are simple, low-stakes, and touch no sensitive data — a low Zapier tier does the job and the data-residency question is moot.
You want to build and change automations yourself, right now, without any technical setup.
If that is you, Zapier is a fine choice and you should keep using it. The businesses that should reconsider are the ones on Microsoft 365, handling financial or customer data, paying a monthly automation bill for a capability their licence already covers — and sending that data offshore to use it.
How to tell which side you are on
Three quick questions:
Are you on Microsoft 365 Business Standard or Premium?
If yes, the automation engine is likely already in your bill.
Do your automations touch financial or customer data?
If yes, where that data goes should be a deliberate choice, not a default.
Are you paying a monthly automation subscription on top of your Microsoft licence?
If yes, it is worth checking whether you are paying twice.
If you answered yes to two or more, you are likely a candidate for keeping automation in-tenant — cheaper, and with your data staying where it belongs. That is exactly the work we do: building invoice processing, payment chasing, compliance tracking, and reporting inside your own Microsoft 365 environment, at a fixed price, on the licences you already own. If you are also weighing up where your data sits more broadly, our free Microsoft 365 security check is a good place to start.
The fine print: Microsoft licensing varies by plan, region, and usage. “Included” refers to core Power Automate, AI Builder, and Power BI capabilities on the relevant Microsoft 365 Business plans at time of writing; premium connectors, higher-volume AI Builder usage, and some advanced features carry additional cost. Data residency configuration depends on your tenant setup and is not the same as data sovereignty. Nothing here is legal, tax, or licensing advice — we confirm exactly what your specific licence covers as part of any engagement. Full engagement terms: secureloop.io/terms.
