Joiner provisioned before 9am
Mailbox, Teams, OneDrive, the shared mailboxes they need, the right plan, MFA enrolled and the laptop signed in. The manager sends one line the day before; the person sits down to a working desk.

Microsoft 365 Business Plans Singapore
A Microsoft 365 tenant is a ledger of seats. Every seat is a person, a mailbox and a monthly charge. The ledger on the right has 48 seats and 11 of them belong to people who left; nobody was told to reclaim them, so they are still on the invoice.
Rezolva has run Singapore infrastructure since 2012, and the Microsoft 365 business tenants we manage are run like that ledger: the right plan per seat, MFA on every one, joiners live on day one, leavers reclaimed the same day, and the invoice read by an engineer who knows who still works there.

THE THREE PLANS
Microsoft 365 business basic, standard or premium: what changes per seat
Microsoft sells three business plans and caps each tenant at 300 seats. The names hide the real difference, which is where the apps run and who is allowed to lose a laptop. Prices below are Microsoft’s published Singapore rates on 7 September 2026, per user per month on an annual commitment, shown in Singapore dollars including 9% GST (Microsoft publishes them in US dollars excluding GST, converted at S$1.2674 to the dollar). Microsoft 365 Business Basic is the mailbox; the other two are the desk and the security around it.

| Purview information protection | — | — | Included |
| Who it fits | Shared PCs, frontline, a mailbox that lives in the browser | Every desk that opens Excel | Every laptop that leaves the office, every finance and director seat |
Microsoft’s Singapore price list now leads with Standard and Premium bundled with Copilot. If a seat does not need Copilot, say so: we quote the plan the seat needs, mixed across the tenant, and the ledger shows which is which. Monthly-commitment pricing exists and costs more per seat; it is the right choice only for genuinely temporary staff.
PAST THE 300-SEAT CAP
Beyond the microsoft 365 business plans: E3, E5 and E7
Every business plan on this page caps the tenant at 300 seats. Past that number — or the day a Singapore company needs 100 GB mailboxes, Windows 11 Enterprise, eDiscovery Premium or an identity plan an auditor will accept — Microsoft moves the conversation to the enterprise plans. The rates below are Microsoft’s published Singapore figures on 7 September 2026, per user per month on an annual commitment, in Singapore dollars including 9% GST (Microsoft publishes them in US dollars excluding GST — E3 US$39.00, E5 US$60.00, E7 US$99.00 — converted at S$1.2674 to the dollar). They are quoted per tenant, so treat them as the shape of the jump rather than a shelf price.
| Per seat | Microsoft 365 E3S$53.88 / user / month | Microsoft 365 E5S$82.89 / user / month | Microsoft 365 E7S$136.77 / user / month |
|---|---|---|---|

| Exchange mailbox | 100 GB, 1.5 TB archive | 100 GB, 1.5 TB archive | 100 GB, 1.5 TB archive |
| Windows edition | Windows 11 Enterprise E3 | Windows 11 Enterprise E5 | Windows 11 Enterprise E5 |
| Identity | Entra ID Plan 1 | Entra ID Plan 2 | Entra ID Plan 2 and Entra Suite |
| Defender for Endpoint / Office 365 | Plan 1 | Plan 2 | Plan 2 |
| Purview audit and eDiscovery | Standard | Premium | Premium |
| Power BI Pro | — | Included | Included |
| Microsoft 365 Copilot | Add-on, S$41.44 | Add-on, S$41.44 | Included, with Agent 365 |
| Who it fits | Over 300 seats, or a compliance requirement Business Premium cannot sign off | Regulated work: finance, healthcare, anyone whose auditor asks for eDiscovery Premium | Tenants putting AI agents to work and wanting one control plane over them |
The honest read for most Singapore SMEs: Business Premium is the ceiling you need. It carries Defender, Intune, Entra ID P1 and Purview information protection at a third of the E3 price, and the 300-seat cap is not a real cap for a fifty-person firm. E3 earns its money on seat count and on Windows Enterprise; E5 earns it on the security and compliance stack, not the mailbox; E7 is E5 with Copilot and Agent 365 already inside. We size the tenant first and tell you which of those three the seat actually needs — often the answer is none of them.
THE PICKER
Pick the microsoft 365 subscription singapore seat count the ledger supports
Value first, then the number. Slide the seat count and switch on what the seats actually do; the panel returns the plan and the licence total at Microsoft’s rate. A Microsoft 365 subscription Singapore firms buy from us rarely lands on one plan for everybody — the warehouse PC and the CFO’s laptop are not the same seat, and the ledger is allowed to say so.

S$32.46Licence per seat / mo
S$779Licences per month
Microsoft Singapore list, annual commitment, in S$ including 9% GST (Microsoft publishes US$ ex GST at S$1.2674 to the dollar). Rezolva’s managed layer is quoted per seat on top and shown on the same ledger.
The picker stops at 300 because Microsoft does; a tenant that expects to pass 300 seats moves to the Enterprise E-plans, which we also run, and the migration is a licence swap rather than a move.
WHAT REZOLVA ADDS
What a microsoft 365 business standard seat includes when Rezolva runs it
Anyone can sell you a licence key; Microsoft will sell it to you directly. What a Microsoft 365 Business Standard seat includes when it sits on our ledger is the work around the key, which is where the tenant either stays tidy or slowly turns into the one on the right of the hero.
MONTHLY
A ledger review, not an invoice
Every month the seat list is compared with the staff list. Plans that are too big for the seat get moved down; seats nobody uses get flagged; the invoice you sign matches the people you employ.
MOVE
Migration from wherever you are
Google Workspace, an old Exchange server, a cPanel host, a reseller who stopped answering. Mail, calendars and files copied with the old system live, the MX record moved on a Saturday, devices tested Monday.
HOTLINE
A Singapore engineer for the tenant
Outlook that will not open, a Teams call that drops, a shared mailbox that stopped syncing. One number, in your time zone, answered by someone who has admin on your tenant and has read its history.
The same layer sits under every plan. Moving a seat from Basic to Premium changes what the seat can do, not who looks after it. It is why the email hosting Singapore hub sends Outlook-first companies here rather than to a licence shop.
JOINER → LEAVER
Joiner to leaver: the microsoft 365 business plans lifecycle in five steps
A tenant is not set up once. It is a queue of people arriving and leaving, and every one of them touches the ledger. Microsoft 365 business plans stay affordable only when the five steps below happen every time, not the first time.
Step 1 · AssignRole decides plan
Each role in the company maps to Basic, Standard or Premium once, in writing. New hires inherit the mapping instead of a guess.
- Step 2 · Provision
Live before the first coffee
Seat added, mailbox created, groups joined, MFA enrolled, laptop enrolled in Intune where the plan has it. Done the evening before the start date.
- Step 3 · Use
Teams, mail, files, monitored
Sign-in risk, forwarding rules, mailbox size and licence use watched on the tenant; anomalies reach a Singapore engineer, not a dashboard nobody opens.
- Step 4 · Leave
Same-day offboarding
Password reset, sessions revoked, devices wiped of company data, mailbox converted to shared for the manager, OneDrive handed over, seat released.
- Step 5 · Reconcile
Ledger and invoice agree
Monthly count of seats billed against staff employed, with the plan mix reviewed. The invoice is a document you can defend to your accountant.
THE BASELINE
Microsoft 365 business premium security baseline: Defender, Intune, MFA
Most of the mailbox takeovers Rezolva has cleaned up in Singapore began with a password and no second factor, on a tenant where nobody had looked at the sign-in log. Microsoft 365 Business Premium exists for the seats that carry that risk; the baseline below is applied to every seat regardless of plan.
EVERY SEAT
MFA and no legacy sign-in
Multi-factor authentication enforced tenant-wide with Microsoft Authenticator, legacy protocols that bypass it switched off, and break-glass admin accounts kept offline and documented.
PREMIUM SEATS
Defender and Intune on the laptops that leave
Defender for Business watches the endpoint; Intune enforces disk encryption, screen lock and the ability to wipe a laptop left in a Grab. Conditional access blocks sign-ins from places the company has never been.
ALL PLANS
A backup that is not Microsoft
Deleted mailboxes are recoverable for 30 days and retention has edges. Where mail and SharePoint are evidence, a separate copy sits outside the tenant; the Microsoft 365 backup page has the numbers.
THE ADD-ON
Microsoft 365 copilot for business: the add-on and when it pays
Copilot is now inside the Standard and Premium bundles and an add-on on Basic at S$24.86 per seat. Microsoft 365 Copilot for business pays for itself on some seats and is an expensive icon on others, and the ledger should know which.
What it does on a seat. Draft and rewrite in Word and Outlook, summarise a Teams meeting the seat missed, ask Excel a question in plain English and get a formula, search across mail, files and chats for the thread that had the number in it. It reads only what the seat already has permission to read.
The permission catch. That last sentence is the whole risk: Copilot surfaces whatever the tenant has over-shared. A SharePoint site with “Everyone” access becomes searchable by everyone. Before Copilot goes on, we run a permissions review; on tenants that grew for a decade it is the longest part of the job.
Our rule for the ledger. Copilot on the seats that write, analyse or sell; Basic without it on the seats that do not. A Singapore SME with 40 seats usually ends up with 10 to 15 Copilot seats, and the monthly difference is visible on the invoice.
Seat rule
- On: finance, sales, directors, anyone drafting proposals or reading long threads
- On, after a permissions review: any seat with access to a SharePoint site older than three years
- Off: shared PCs, frontline and warehouse seats, the scanner mailbox
- Typical Singapore SME of 40: 10 to 15 Copilot seats, visible as its own line on the invoice
THE NUMBER, LATE
Microsoft office 365 business plans priced per seat
The licence part is public: Microsoft publishes it and we do not mark it up. What you are buying from us is the ledger — the setup, the monthly review, the joiner and leaver work and the hotline — quoted per seat on top. Microsoft Office 365 business plans stopped being called that in 2020; the search term survives, the plans below are what it means now.
PLAN 01

PLAN 03

Indicative pricing — licence figures are Microsoft’s published Singapore rates on 7 September 2026 (Microsoft lists them in US dollars excluding GST — US$7.00 / 23.50 / 32.00; shown here in Singapore dollars at S$1.2674 per US dollar with 9% GST added, annual commitment) and move with Microsoft, the exchange rate and the GST rate; Rezolva’s managed layer per seat is quoted once the seat ledger has been read.

FAQ
Microsoft 365 for business plans — eight straight answers
Only past 300 seats or past what Business Premium can sign off. Microsoft’s Singapore list on 7 September 2026 is US$39.00 for E3, US$60.00 for E5 and US$99.00 for E7 per user per month on an annual commitment, excluding GST — about S$53.88, S$82.89 and S$136.77 with 9% GST at S$1.2674 to the dollar. What you buy is the seat cap lifted, a 100 GB mailbox with a 1.5 TB archive, Windows 11 Enterprise and, on E5, Defender and Purview at Plan 2 with eDiscovery Premium; E7 is E5 with Microsoft 365 Copilot and Agent 365 inside. For a fifty-person Singapore firm, Business Premium usually does the same job for a third of the money, and that is what we will tell you.
Basic is the mailbox and the web versions of Office with Teams; Standard adds the desktop apps and, in the current Singapore bundle, Copilot; Premium adds the security layer — Defender for Business, Intune device management, Entra ID P1 conditional access and Purview information protection. All three carry a 50 GB mailbox and 1 TB of OneDrive. The tenant can mix them, so the right answer is per seat, not per company.
Microsoft’s published Singapore rates on 7 September 2026 are about S$9.67 per user per month for Business Basic, S$32.46 for Business Standard with Copilot and S$44.21 for Business Premium with Copilot, on an annual commitment and including 9% GST — Microsoft lists them in US dollars excluding GST (US$7.00 / 23.50 / 32.00) at S$1.2674 to the dollar. Copilot as an add-on is S$24.86 and Defender for Business S$4.14. Rezolva quotes its managed layer per seat on top and shows both lines on the same ledger.
Yes, and you should. A tenant of 40 seats is usually a handful of Premium seats for directors and laptops, Standard for the desks and Basic for shared or frontline PCs. Microsoft caps each business plan at 300 seats per tenant; past that the Enterprise E-plans take over without a migration.
There is no free business tier. Microsoft offers a one-month trial on Standard and Premium that converts to a paid annual subscription unless cancelled, which is exactly how ghost seats begin. We set trials up with an end date on the ledger and a reminder to the person who asked for it.
Same day: password reset and sessions revoked, company data wiped from their devices, the mailbox converted to a shared mailbox the manager can read, OneDrive files transferred, and the licence released so it stops being billed. The seat shows as reclaimed on the ledger, and the next joiner takes it.
No. It earns its cost on seats that write, analyse or sell all day, and it is a S$24.86-a-month icon on a shared PC. Before it goes on any seat we review SharePoint and OneDrive permissions, because Copilot surfaces whatever the tenant has over-shared. Most Singapore SMEs land at a quarter to a third of seats.
Yes. Mail, calendars, contacts and Drive files are copied into Exchange, OneDrive and SharePoint while the old system stays live, the MX record moves on a Saturday, and devices are reconfigured before Monday. If Google Workspace is actually the better fit, the Google Workspace Singapore page is where we would send you instead, and we say so.
Typing microsoft for business 365 into a search box usually means a company of five to fifty people that has outgrown a free mailbox. Most of them need Business Standard for the desks, Basic for anyone who never opens Excel and Premium for the two or three seats holding the bank tokens. If the whole company works in a browser, Basic across the board with Copilot on the two writers is a perfectly good answer.
