Microsoft 365 Pricing for Small Business

📋 The Short Version

Microsoft has changed how small businesses in Australia purchase Microsoft 365. The new model is called the Cloud Solution Provider program — known as CSP. In plain terms, this means that instead of buying Microsoft 365 directly from Microsoft, small businesses now purchase and manage their licences through a local IT partner like DM1. This gives you a single point of contact, local support based in Perth, and the same pricing as going direct — often with better outcomes because your IT partner knows your business.

Microsoft 365 pricing in Australia varies depending on the plan and commitment length. This guide covers current month-to-month pricing in Australian dollars including GST, explains what each plan includes, and flags an upcoming price increase in July 2026 that businesses should be aware of.

For businesses with fewer than 300 staff, the CSP model is now the standard path for purchasing Microsoft 365 Business Basic, Business Standard, and Business Premium. This page explains what that means for your business and what to expect if you are not already set up this way.

🔍 Why Microsoft Changed How Small Businesses Buy Microsoft 365

Microsoft's Cloud Solution Provider program (CSP) is Microsoft's official licensing model for small and medium businesses. Rather than every small business managing a direct account with Microsoft, CSP places a local IT partner — like DM1 in Perth — as the point of contact for purchasing, billing, and support. Microsoft designed this model because small businesses get better outcomes when a local partner who knows their environment is managing their licences, rather than dealing directly with a large global organisation.

The reasons Microsoft has moved in this direction include:

• Local support that knows your business — Microsoft relies on CSP partners like DM1 to provide hands-on, localised management and support for small businesses across Perth and Western Australia. Your IT partner understands your environment in a way a global helpdesk cannot.
• Flexible monthly billing — Microsoft 365 licence counts can be adjusted as your team grows or changes. You are not locked into paying for seats you no longer need.
• One agreement for everything Microsoft — Microsoft 365, Azure, Defender, Intune, and Copilot are all managed under a single CSP arrangement, simplifying your licensing and billing.
• Legacy purchasing options have been removed — Microsoft ended its older Open Licence program in 2022 and has removed perpetual (one-off purchase) Office licences from most SMB channels. CSP is now the standard path for small business Microsoft 365 pricing in Australia.

⚡ What Has Changed with Microsoft 365 Licensing

The Old Way of Buying Microsoft Office is Gone

Many small businesses previously purchased Microsoft products through a program called Open Licensing — either buying a one-off perpetual licence for Office, or renewing annually through a reseller. Microsoft ended its Open Licence program for new purchases in late 2022. If your business was on this path, it is no longer available. Microsoft 365 subscription licences through CSP are now the standard route for small businesses in Australia.

One-Off Office Purchases Are No Longer Available for Most Small Businesses

Microsoft has removed one-time purchase options for Office 2019 and Office 2021 from most small business channels. Rather than buying Office once, businesses now subscribe to Microsoft 365 monthly or annually — which includes the latest version of Office apps plus Teams, OneDrive, and other cloud services.

How Microsoft 365 Subscription Commitments Work

Microsoft introduced a framework called the New Commerce Experience (NCE) which changed how Microsoft 365 subscriptions are structured. The key things to understand are:

• Month-to-month plans give you full flexibility to cancel or change at any time, but cost around 20% more than committing annually. This is the pricing shown in the plan cards below.
• Annual plans lock in your per-seat pricing for 12 months and are approximately 20% cheaper than month-to-month. This is the most common choice for stable small business teams.
• Three-year plans offer a further discount for businesses with very stable staffing and long-term Microsoft 365 requirements.
• Reducing licences mid-term is generally not permitted under annual or three-year commitments — you are committed to the number of seats you sign up for until the renewal date.

What Stays Exactly the Same

Moving to the CSP model does not affect any of the following — your day-to-day experience of Microsoft 365 is completely unchanged:

• Your existing Microsoft 365 tenant, data, and user accounts remain completely unchanged.
• Email addresses, OneDrive, SharePoint, and Teams continue to function as normal.
• End users do not need to learn a new system or change how they work.
• There is no downtime or service interruption during the transition.

📦 Microsoft 365 Pricing — Current Australian Plans for Small Business

For businesses with fewer than 300 staff, Microsoft 365 comes in three main plans. All prices below were verified directly on Microsoft's Australian website on 21 February 2026. Prices are Microsoft's publicly listed month-to-month rates in Australian dollars, inclusive of GST, and are the same whether you buy through DM1 or direct — the difference is that purchasing through DM1 includes local Perth-based management and support. Annual commitment pricing is approximately 20% lower — contact DM1 for a personalised quote.

• Business Standard is the most popular choice for professional services firms (legal, accounting, medical reception) needing the full Office desktop suite, Teams meetings, and shared calendars.
• Business Premium — DM1's recommendation — is strongly suited to any business handling sensitive client data, including healthcare, legal, and financial services. It includes Microsoft Defender for Business and Intune, providing enterprise-grade endpoint security at an SMB price point.
• Business Basic suits businesses that work primarily in a browser and don't need installed Office apps — for example, retail or hospitality staff who only need email and Teams.

🤝 What Managing Microsoft 365 Through DM1 Looks Like

When DM1 manages your Microsoft 365 licences through the CSP model, your licensing becomes an ongoing managed service rather than something you have to think about. Here is what that means practically for your business.

One Monthly Invoice

All your Microsoft 365 licensing is consolidated onto a single invoice from DM1 each month. No separate Microsoft billing, no surprise renewals — just a clear, predictable cost for your Microsoft 365 pricing each month.

We Handle Licence Changes for You

When you hire someone new, DM1 sets up their Microsoft 365 account and adds a licence. When someone leaves, we remove it promptly — meaning you are never paying for Microsoft 365 seats that are not being used. For small Perth businesses where every dollar counts, this matters.

No Need to Deal with Microsoft Directly

You do not need to manage a relationship with Microsoft's billing or sales systems. DM1 handles all licence changes, billing questions, and renewals on your behalf — which is particularly valuable for businesses without a dedicated IT person on staff.

Direct Access to Microsoft Support Through DM1

As a Microsoft CSP partner, DM1 can raise technical issues directly with Microsoft on your behalf with faster escalation than standard end-user support. If something goes wrong with your Microsoft 365 environment, you have a local team in your corner rather than navigating Microsoft's global support queue on your own.

Licence Reviews at Every Renewal

DM1 reviews your Microsoft 365 licence count and plan at each renewal to make sure you are on the right plan at the right price. We will flag if a newer Microsoft 365 feature — such as Microsoft Copilot or an upgraded security plan — would benefit your business, and advise accordingly.

🔒 Security Considerations for Businesses Under 50 Users

One of the most significant benefits of the CSP model — particularly at the Business Premium tier — is access to enterprise-grade security tools that were previously out of reach for smaller organisations.

Microsoft Defender for Business

Included in Microsoft 365 Business Premium, Defender for Business provides endpoint detection and response (EDR) capabilities across Windows, macOS, iOS, and Android devices. For businesses with 10–300 users, this replaces the need for a separate third-party antivirus product and provides centralised threat visibility through the Microsoft 365 Defender portal.

Microsoft Intune (Mobile Device Management)

Business Premium includes Intune, which allows DM1 to enforce security policies on devices accessing your Microsoft 365 environment. This is particularly relevant for businesses where staff use personal phones or laptops to access work email — Intune enables conditional access policies that ensure only compliant devices can connect.

Azure Active Directory Premium P1

Business Premium includes Azure AD P1, which enables Conditional Access policies. This allows DM1 to require multi-factor authentication (MFA) based on conditions such as location, device compliance status, or sign-in risk — significantly reducing the risk of account compromise.

Microsoft Secure Score

Once your environment is managed through the Microsoft 365 admin centre, DM1 regularly reviews your Microsoft Secure Score — a dashboard that benchmarks your security configuration against Microsoft's recommended practices. For businesses in healthcare or legal sectors, this supports compliance obligations under Australian Privacy Act requirements.

❓ Do I Have to Change How I Buy Microsoft 365?

Microsoft does not use the word "mandatory", but for small businesses in Australia with under 300 staff, the CSP model is now effectively the only practical option. The alternatives that existed previously have been removed or restricted:

• Open Licence — ended for new purchases in late 2022. No longer available.
• Buying directly from the Microsoft website — still possible, but limits your ability to have a partner like DM1 manage and support your environment. You handle billing, licence changes, and support yourself.
• Enterprise Agreement — requires a minimum of 300 seats. Not relevant for small businesses.

If you want local, managed support for your Microsoft 365 environment in Perth, the CSP model through a partner like DM1 is the right path — and the Microsoft 365 pricing is identical to buying directly from Microsoft.

🚀 What Happens When You Move to DM1 as Your Microsoft 365 Partner

If you are currently purchasing Microsoft 365 outside of the CSP model, switching to DM1 is straightforward and completely invisible to your staff. Nothing changes for your users — here is what the process involves:
