Small business owners in Portugal comparing Microsoft 365 Business Basic, Standard, and Premium usually get stuck on the same question: which tier actually matches how the team works, not just what Microsoft's pricing page implies. This ranking sorts the business tiers by real usage patterns for companies under 50 seats in 2026, with a specific note on Microsoft 365 Empresas Basic — the entry tier most searched by Portuguese SMBs.
- Microsoft 365 Empresas Basic (Business Basic) wins for teams under 10 people who only need web apps: Buy.
- Microsoft 365 Business Standard is the default pick for most SMBs needing desktop Office: Buy.
- Business Premium adds Intune and Defender for Business, worth it for law firms, clinics and accounting firms: Buy.
- Microsoft 365 E3 is overkill under 300 seats in 2026: Skip until you outgrow the cap.
- Apps for Business skips hosted email entirely — fine only if you already run mail elsewhere: Hold.
Why this matters
Most small businesses in Portugal overpay by defaulting to whatever tier a reseller quotes first, or underpay by picking Basic and then discovering they need desktop Outlook six months in. The five current Microsoft 365 for business tiers — Basic, Apps for Business, Standard, Premium, and E3 — cap at 300 users each except E3, and the feature gap between them is bigger than the price gap suggests.
VOLL sells Microsoft 365 licenses to Portuguese businesses with local invoicing and support, which matters more than it sounds once you factor in tenant setup and license swaps mid-year. Get the tier wrong and you're either paying for security features nobody configures, or missing the device management that a single lost laptop makes expensive.
How we ranked
The ranking below is built on Microsoft's published feature sets for the 2026 business tier lineup — user caps, mailbox storage, device management, and security add-ons — cross-checked against the operational patterns of the industries VOLL serves most: accounting, law, healthcare, construction and hospitality. No tier gets a Buy verdict unless its feature set matches an actual use case, not just a lower list price.
The ranked list
1. Microsoft 365 Business Basic (Empresas Basic) — the safe pick for the smallest teams
Business Basic gives every user a 50GB mailbox, 1TB of OneDrive storage, and web/mobile versions of Word, Excel and Outlook — no desktop install included. The user cap sits at 300, same as every other Business tier, so growth isn't the limiting factor here.
This tier makes sense for a 3-8 person team that lives in a browser: quotes, invoices, basic email, shared files. Buy if nobody on the team needs offline Word or Excel; Skip it the moment someone asks for the desktop app.
2. Microsoft 365 Apps for Business — desktop apps without hosted email
This tier installs full desktop Office — Word, Excel, PowerPoint, Outlook — on up to 5 devices per user, but it does not include Exchange-hosted business email, Teams, or SharePoint. It's built for companies that already run mail through another provider.
It's a narrow fit: fine if your domain email already lives elsewhere and you only need the desktop apps, but a poor match for anyone who wants one vendor for mail and apps. Hold unless your email setup is already locked in with another provider.
3. Microsoft 365 Business Standard — the default for most SMBs
Standard bundles everything in Basic plus desktop Office apps, hosted business email through Exchange, Teams, and SharePoint, still under the 300-user cap. This is the tier that fits a 10-50 person company running mixed office and field work without needing device-level security controls.
For a construction company juggling site staff and office admin, or a restaurant group running back-office accounting across multiple locations, Standard covers desktop apps, shared calendars, and Teams video calls in one license. Buy — this is the tier most SMBs should start pricing against, not Basic.
4. Microsoft 365 Business Premium — the wildcard for regulated data
Premium adds Intune device management, Microsoft Defender for Business, and Conditional Access on top of everything in Standard, still capped at 300 users. The jump matters most for businesses handling client data that a lost or stolen device would turn into a real liability.
Accounting and bookkeeping firms holding client tax records, law firms managing case files, and healthcare clinics under patient confidentiality rules are the clearest fits. Buy if your business handles regulated client data on staff laptops or phones; Skip if your team works entirely from a fixed office network with no mobile access.
5. Microsoft 365 E3 — overkill until you outgrow 300 seats
E3 removes the user cap entirely and adds advanced compliance and data loss prevention tools built for larger organizations. For a company under 300 employees, none of that changes daily operations, and the licensing cost jump isn't justified by features nobody on a 40-person team will touch.
Wait on E3 until headcount or compliance requirements force the move — for 2026, almost no business under 300 seats needs it on day one.

Where to buy
Buy Microsoft 365 licenses from a reseller that quotes prices without VAT for business buyers and handles tenant setup, not just a checkout link — license mismatches at setup cost more time than the license itself. VOLL sells Microsoft 365 alongside ERP integration for Primavera and Cegid, which matters if your Standard or Premium license needs to sync with existing accounting software.
For sector-specific setups — a restaurant group managing multiple locations or a construction firm coordinating site teams — check whether the reseller offers install support beyond just license activation. A license with no configuration help just moves the problem from "which tier" to "who sets it up."
FAQ
What is Microsoft 365 Empresas Basic?
Microsoft 365 Empresas Basic is the Portuguese name for Microsoft 365 Business Basic, the entry-level business tier with web-only Office apps, a 50GB mailbox, and 1TB of OneDrive storage per user in 2026.
Is Microsoft 365 Business Standard better than Basic for small businesses?
Yes, for most teams over 10 people, because Standard adds desktop Office apps and hosted business email that Basic lacks. Basic only makes sense when the whole team works entirely from a browser.
How much does Microsoft 365 Business Premium cost compared to Standard?
Premium costs more per user than Standard because it adds Intune device management, Microsoft Defender for Business, and Conditional Access. Check current pricing directly with a licensed reseller, since Microsoft adjusts per-user rates periodically.
Do I need Microsoft 365 E3 for a small business?
No, E3 is built for organizations approaching or exceeding the 300-user cap on Business tiers. Under 300 seats in 2026, Business Premium covers the same security ground at a lower cost.
Can I mix Microsoft 365 license tiers in one company?
Yes, a single Microsoft 365 tenant can run different tiers per user — for example, Basic for reception staff and Premium for accounting staff handling client data. This is a common way to control cost without downgrading security where it matters.
Does Microsoft 365 Business Basic include desktop Word and Excel?
No, Business Basic only includes web and mobile versions of Office apps. Desktop installs require Apps for Business, Standard, Premium, or E3.
Is Microsoft 365 Business Premium worth it for a law firm?
Yes, for firms handling client case files on staff laptops or phones, because Premium adds device management and Conditional Access that Standard does not include. The added security layer matters more than the price difference for firms under confidentiality obligations.
What's the user limit on Microsoft 365 Business plans?
Business Basic, Apps for Business, Standard, and Premium all cap at 300 users. Businesses expecting to exceed that in 2026 should plan a move to E3 ahead of time, not after hitting the wall.
One last thing
A detail most SMBs miss: Microsoft 365 tenants let you assign different tiers to different users on the same domain, so a 20-person company doesn't need to put everyone on Premium just because the accounting team handles sensitive files. Put the office admin and reception on Standard, put anyone touching client data or company laptops on Premium, and the total license bill drops without losing the security coverage where it actually counts.
