Most Microsoft 365 invoices arrive monthly as a single line item — “Microsoft 365 Business Premium × N seats” — and get filed under “obviously necessary, don’t think about it.” That’s fine until you realise you’ve been paying for licences that nobody’s actively using, or that the seat count never came down when someone left.
Here’s how to read your invoice properly and what the numbers should look like in 2026.
What’s on the invoice
A typical AU SMB M365 invoice (purchased via a CSP partner like Pax8) has three things on it:
- The subscription line(s) — “M365 Business Premium × 8 users” — the bulk of the bill
- Any add-on subscriptions — Defender for O365 P2, Teams Phone, Audio Conferencing, Power BI Pro
- GST — at 10% on the total
That’s it. If your invoice has line items you don’t recognise, ask your provider what they’re for. There’s no hidden category of charges in M365 — every line maps to a subscription you (or someone) authorised.
What the seats should cost in 2026
Current Australian pricing for the major Business-tier SKUs:
| SKU | Approximate per-user/month inc-GST |
|---|---|
| Microsoft 365 Business Basic | ~$11.55 |
| Microsoft 365 Business Standard | ~$23.10 |
| Microsoft 365 Business Premium | ~$36.75 |
| Microsoft 365 Apps for Business | ~$13.65 |
These are the wholesale prices through Pax8 and similar CSP partners. If you’re buying direct from Microsoft, you might be paying the same or slightly more depending on your discount.
If your invoice shows materially higher per-seat prices, ask:
- Is your MSP reselling at cost? Most CSP partners resell M365 at cost + a small margin (5-10%). Some MSPs resell at cost + 30-50% margin, which is when it starts to feel exploitative.
- Are you on a price-locked older SKU? Microsoft occasionally rolls out price increases; locked-in older prices can be lower or higher than current.
- Are there add-ons bundled in that aren’t broken out? If “M365 BP × 8 users = $400/month” the maths only works at ~$50/user, which is well above wholesale. There’s an add-on in there.
The ‘too many seats’ problem
This is the most common waste: seat count never reduces when staff turn over.
Process to fix it:
- Pull your current invoice. Note the seat count per SKU.
- Sign into the M365 admin centre. Go to Users → Active users.
- Compare. If your invoice shows 12 BP seats but you have 9 active users, you’re paying for 3 unused licences (~$110/month wasted).
- Reduce the seat count via your CSP partner’s portal (or have them do it for you).
A 30-second check that saves $1,000+ a year for many SMBs.
The ‘wrong SKU’ problem
Are your users on the right SKU? Common patterns to check:
- Knowledge workers on Business Basic — they get Teams, Exchange, SharePoint, OneDrive, but no installed Office apps. If they’re working in Excel daily on a desktop, they need Apps for Business as an add-on (or move up to Business Standard).
- Field staff on Business Standard — they get everything but no advanced security/Intune/Defender. For mobile workforce with company-owned devices, Business Premium pays back fast in security alone.
- Admins on basic SKUs — Microsoft 365 admins should have an account that includes Defender for Business as a minimum. Otherwise you’re managing tenant security through the same account that has personal-grade email.
What about Microsoft 365 Copilot?
As of 2026, Copilot is sold as a per-user add-on at ~$45/user/month inc-GST (variable; check current pricing). It requires a base licence (BP or Apps for Business minimum). It’s not in the standard Business Premium bundle.
The honest take: Copilot pays back for some users (knowledge workers writing a lot, analysts working with Excel/Power BI heavily) and isn’t worth the spend for others (mostly-email users, on-the-tools field staff). Don’t bulk-license your whole company; pick the 2-3 users who’d genuinely benefit, measure the time saved, decide from there.
What good MSP invoicing looks like
If we manage your M365 (any tier from Solo Secure through Premium), the M365 licence cost is bundled into your tier price at cost. Your invoice has one line: the tier × seats. The wholesale Microsoft pricing is visible in our quote and you can verify against Microsoft’s published pricing any time.
We never make margin on Microsoft licensing. We make margin on managing it well.
