What Microsoft Does Not Publish for This Product

The following are commonly asked about but are not stated on any current official Microsoft source for this product, so SourceIT does not quote them: a reconciled figure for the per-user storage accrual, a minimum purchase quantity and the product name and commerce identifier as documented Microsoft references. We would rather leave a field blank than print a figure we cannot substantiate.

SourceIT sells this as a twelve-month subscription with a GST invoice in Singapore. The subscription is a right to use the service for the term, not a perpetual licence: when the term ends the entitlement ends unless it is renewed.

Microsoft's lifecycle listing places Business Central under the Modern Lifecycle Policy, with a start date of 1 November 2016 and a retirement date shown as "In Support". The Modern Lifecycle Policy carries an obligation on the customer as well as on Microsoft: "Customers must stay current as per the servicing and system requirements published for the product or service", and Microsoft commits to "a minimum of 12 months' notification prior to ending support if no successor product or service is offered". In practice that means roughly six months on any given major version before the update is enforced. Note that Microsoft frames this as an update enforcement timeline rather than a support-ends date, and publishes no per-version end-of-support date for Business Central online. Separate Fixed-policy dates exist for Business Central on-premises and do not apply to this subscription.

Talk to our team before the renewal date rather than after it. Seat counts, mid-term changes and co-terming with the rest of your Microsoft estate are all easier to arrange in advance, and we can quote the alternatives if a bundle would work out better for you.

Support and Entitlement Position

This is a software subscription, not hardware. It carries no hardware warranty, and any warranty term you see on a hardware listing does not apply here. What you are buying is a twelve-month right to use the service, together with SourceIT's local support in Singapore. Microsoft's own condition is that technical and billing support for a subscription bought through a partner runs through that partner, so for this subscription that means us: raise the ticket with SourceIT and we escalate to Microsoft where it needs to go. Renewal, seat changes and co-terming are handled on your SourceIT account. Ask our team for the current entitlement position in writing with your quotation.

Before buying capacity, find out how much you already have. The baseline is "up to 80 GB plus an allowance per licensed Essentials or Premium user", and on a tenant with a reasonable user count that allowance is substantial. The complication is that Microsoft publishes the per-user figure two different ways — 2 GB and 3 GB on one page, 3 GB and 5 GB in the licensing guide — so the arithmetic depends on which applies. Ask us to establish your actual entitlement before you size the purchase.

Understand what running out actually costs you. Microsoft states that exceeding the paid limit "doesn't interrupt transaction processing within the existing environments", but that you "can't create new environments or copy existing environments" until you free space or buy more. The pain therefore lands during an upgrade test or a go-live rather than during normal trading — which is exactly when you can least afford it. Buy the headroom before the project, not during it.

If you expect to grow steadily rather than in one jump, note the gating rule: the cheaper Overage (1 GB) add-on is only available once you hold at least one 100 GB add-on. Buying this unit is what opens the cheaper incremental route for later.

Where a figure appears on this page it is quoted from one of these Microsoft pages; where Microsoft publishes nothing, this page says so rather than filling the gap.

How much database capacity do we already have?

Microsoft's baseline is "up to 80 GB plus an allowance per licensed Essentials or Premium user". The per-user figure is where it gets awkward: Microsoft's Managing capacity page says 2 GB per Essentials user and 3 GB per Premium user, while the September 2026 licensing guide says 3 GB and 5 GB. Both are current Microsoft sources and neither reconciles the other. We publish both and will establish your actual entitlement in writing before you size a purchase.

What happens if we run out of capacity?

Trading carries on. Microsoft states that exceeding the paid limit "doesn't interrupt transaction processing within the existing environments". What stops is creating new environments and copying existing ones, until you free space or buy more — which means the problem surfaces during an upgrade test or a go-live rather than during normal work. Buy headroom ahead of a project rather than in the middle of one.

Is there a cheaper way to add small amounts?

Yes, but it is gated on this product. Microsoft publishes a Database Capacity Overage (1 GB) add-on which "is only available for the customers who purchased at least one Dynamics 365 Business Central Database Capacity (100 GB) add-on". So buying this 100 GB unit is what opens the cheaper incremental route for future growth.

Does an extra environment come with capacity too?

Yes. Microsoft states that each additional production environment "comes with three additional sandbox environments and 4 GB additional, tenant-wide database capacity". That 4 GB stacks with the baseline and with any capacity add-ons.

Is there a minimum purchase?

Microsoft publishes none for this add-on. Practical minimums come from the purchasing programme rather than the product, so ask our team what applies on the route we would quote you.
