Microsoft sells its Enterprise suites to new subscribers with Teams licensed separately; we include the right Teams option in the quote. Plan contents checked October 2026.
New Enterprise subscriptions are sold without Teams, so a Teams licence is added alongside. Existing subscriptions that already include Teams can usually keep it at renewal. We check which applies to you before quoting. More on our Teams licence page.
Microsoft raised the Office 365 E3 list price from 1 July 2026, alongside Microsoft 365 E3 and E5. Your price depends on the number of users, the Teams option and monthly or annual commitment. We quote in AED, usually the same working day.
We quote per user in AED with 5% VAT shown separately, supply against your company LPO and issue a VAT invoice. No company credit card or overseas billing is needed.
Annual commitment gives the best per-user rate and still lets you add users at any time. Monthly commitment costs more per user but lets you reduce seats month to month.
Tenant setup, mailbox and file migration, user onboarding and activation are included at no extra charge on Microsoft licences bought from Proto Link.
We track your renewal date and remind you before it, so prices, seat counts and plans can be reviewed instead of auto-renewing unchanged.
