Two products from the same vendor, one letter apart, and a constant source of confusion in Australian buying conversations. We hear it most weeks: a finance lead asks why their Microsoft 365 renewal doesn't include the CRM the sales team was promised, or someone budgets for Dynamics 365 assuming Word, Excel and Teams come bundled in. They don't. Dynamics 365 and Microsoft 365 are genuinely separate products, sold and licensed separately, and clearing that up before you sign anything saves real money and real awkwardness.
This guide explains what each one actually is, why Microsoft named them so similarly, where they overlap, and roughly what the entry tiers cost in Australia. Pricing here is indicative AUD list (ex GST) — confirm at purchase, because Microsoft adjusts list prices and there are changes landing in mid-2026.
The short version
Microsoft 365 is your productivity and collaboration suite — the everyday tools your whole organisation uses to get work done. Dynamics 365 is a family of business applications that run specific operational functions, principally CRM (customer relationship management) and ERP (enterprise resource planning). One keeps your people working; the other runs your sales, service, finance and operations processes.
- Microsoft 365 = email, documents, meetings, chat, file storage, security. Bought per user, for most or all staff.
- Dynamics 365 = sales pipeline, customer service, finance, supply chain, field service. Bought per user, usually for the teams that need it (sales reps, service agents, finance).
They are not tiers of the same thing. You can run Microsoft 365 with no Dynamics at all — most Australian businesses do. You can also run Dynamics 365 alongside Microsoft 365, which is the common pattern, because they integrate well. But they are two purchase decisions, two licence lines, and often two different budget owners.
What Microsoft 365 actually includes
Microsoft 365 is the rebrand of what people still call Office plus the cloud services around it. On a typical business plan you get Outlook and Exchange email, the Office apps (Word, Excel, PowerPoint, OneNote), Teams for meetings and chat, OneDrive and SharePoint for file storage, and — depending on the tier — security and device management through tools like Defender and Intune.
For Australian small and mid-size businesses the entry points are Business Basic at an indicative AUD 9 per user/month (web and mobile apps, no desktop Office), Business Standard at an indicative AUD 18.70 per user/month (adds the desktop apps), and Business Premium at an indicative AUD 32.90 per user/month (adds advanced security and device management). All figures indicative AUD list — confirm at purchase. Note that Microsoft has flagged increases to some Business plans from 1 July 2026, so the Basic and Standard numbers in particular are worth re-checking before you commit.
What Dynamics 365 actually includes
Dynamics 365 is not one app — it's a catalogue. The pieces you buy depend on what business process you're trying to run. The CRM-side apps cover customer-facing work: Dynamics 365 Sales (pipeline, leads, opportunities, forecasting), Customer Service (case management, agent desktop, knowledge base), and Field Service (scheduling technicians). The ERP-side apps cover back-office and operations: Business Central (finance and operations for SMBs), and Finance plus Supply Chain Management (for larger enterprises).
You licence the specific app a person needs. A sales rep gets a Sales licence; a contact-centre agent gets a Customer Service licence; a financial controller gets a Business Central or Finance licence. This is why Dynamics costs more per seat than Microsoft 365 — it's running a core business system for that role, not general productivity.
Indicative Australian Dynamics 365 pricing
For the two most commonly asked-about CRM apps, the Australian entry tiers look like this:
- Dynamics 365 Sales Professional — indicative AUD 97.30 per user/month. Core pipeline, lead and opportunity management for smaller sales teams. Sales Enterprise (more automation, customisation and Copilot capability) sits higher, around an indicative AUD 157 per user/month.
- Dynamics 365 Customer Service Professional — indicative AUD 74.80 per user/month. Case and knowledge management for service teams. Enterprise and Premium tiers add multi-channel and deeper AI, at materially higher prices.
Why people conflate them
Three reasons, mostly. The naming — '365' on both, same colour palette, same vendor. The overlap — both surface inside Teams and Outlook, so a Dynamics record can appear right next to your email and it feels like one product. And the bundling myth — because Microsoft 365 bundles so much, people assume Dynamics is just another module inside it. It isn't. There is no Microsoft 365 plan that includes a Dynamics 365 CRM or ERP licence.
The one genuine shared foundation is the Power Platform and Dataverse — the data layer and low-code tooling that both ecosystems can tap. That's real integration, and it's why Dynamics feels native when you're working in Microsoft 365. But shared plumbing is not the same as a shared licence.
How to decide what you need
Start by separating the two questions. Everyone needs productivity, so Microsoft 365 is almost always a given — the only decision is which tier, and that's driven mainly by your security and compliance needs (Business Premium if you want the security stack; Standard if you just need the apps and email).
Dynamics 365 is a process decision, not a headcount one. Ask: do we have a specific business function — sales, service, finance — that's currently run on spreadsheets, a disconnected tool, or nothing structured at all? If yes, that's where a targeted Dynamics app earns its keep, licensed only for the people in that function. You almost never buy Dynamics for the whole org.
What we'd actually do
In practice, we'd sort users into two buckets. First, everyone goes onto an appropriately-tiered Microsoft 365 plan — for most Australian SMBs that means Business Premium for the security, or Standard where budget is tight and security is handled elsewhere. Second, we'd identify the handful of roles that need a real business system — the sales team, the service desk, finance — and licence just those people on the relevant Dynamics app, starting with the Professional tier and stepping up to Enterprise only where the extra automation and Copilot features justify the cost.
We'd also pressure-test whether you need Dynamics at all before recommending it. Plenty of smaller teams run a perfectly good pipeline inside Microsoft 365 and the Power Platform without paying for a full CRM seat. The right answer is the smallest licensing footprint that covers the work — not the biggest one a price list will let you buy. Price the actual seat mix in AUD ex GST at purchase, factor the mid-2026 Microsoft 365 changes into any multi-year view, and don't let the matching '365' branding talk you into a product you don't need.
