Microsoft licensing experts are independent advisors who find the cheapest compliant licence position for your business and hold you there between renewals. Microsoft 365 editions, Copilot add-ons, Azure consumption and on-prem rights change constantly. We turn that complexity into a clear, defensible position and the lowest cost that supports it.

This is the standing advisory that keeps your Microsoft estate clean between deals, and it is distinct from a one-off renewal. For the deal itself, see our Microsoft negotiation advisors, and for the full product map our Microsoft vendor intelligence hub goes vehicle by vehicle. Here the focus is your live licence position and the cost it carries every day.
Talk to a Microsoft licensing expertRight-sizing Microsoft 365, Copilot, Azure and on-prem rights with independent, ex-vendor expertise.
Our team includes people who have worked inside Microsoft licensing and large resellers. We know how SKUs are priced, where rights overlap, and which entitlements customers routinely over-buy. Because we are independent, that knowledge works for your budget rather than a sales quota.
We right-size Microsoft 365 plans across E3, E5 and the F series to real user profiles, remove duplicate or unused entitlements, validate Copilot and security add-ons before you commit, and align Azure spend with actual consumption. The result is lower cost now and a defensible position at your next audit or renewal.
We maintain a clean entitlement baseline so you are never renewing or defending an audit from a standing start. That baseline feeds directly into EA renewal planning and audit defense when you need them.
Microsoft licensing is a small number of high stakes decisions repeated across thousands of seats. Get the rules right once and the saving compounds every month.
Microsoft 365 is the largest line for most organisations, and the E3 to E5 step-up is the single biggest swing. E5 bundles advanced security, compliance and voice. Many buyers already own those capabilities in point tools or never switch them on. We profile users against real work, move deskless and frontline staff to F1 and F3 where the rights fit, and hold the E3 base where the extra E5 features would sit idle. Microsoft Product Terms set the exact use rights for each plan, and we apply them line by line rather than the sales narrative. The full edition comparison sits in our Microsoft 365 E3, E5 and F3 comparison.
On-prem rights are where compliance risk hides. Windows Server and SQL Server moved to core based licensing, with minimums per physical core and Software Assurance deciding whether your licences can move between hosts. Client Access Licences still apply to Windows Server, Remote Desktop Services and other workloads, and the User versus Device choice changes the count materially. We read these rules against your deployment, including the virtualisation and failover rights set out in the Microsoft Product Terms and the Microsoft Licensing Briefs, so an audit finds nothing it can charge for.
Copilot and Azure are the fastest moving lines. Microsoft 365 Copilot carries a per user prerequisite and a real annual cost, and first wave adoption rarely matches the seats bought. We size it to proven usage and stage the commitment. Azure spend gets matched to a real consumption curve so a commitment becomes a discount, not an unplanned overage. Where a renewal is in range, our Microsoft EA renewal strategy picks up the commercial work.
A four-stage method that turns a messy estate into a clean, defensible and cheaper licence position.
We pull your entitlements, deployment data and assignment reports across Microsoft 365, Azure, Windows Server and SQL Server, then reconcile what you own against what you actually run.
We test every position against current Microsoft Product Terms and Licensing Briefs: edition rights, CAL rules, core minimums, Software Assurance benefits and Copilot prerequisites. Gaps and overlaps both surface here.
We move seats to the edition that fits, retire duplicate and unused entitlements, and close any compliance gap before it becomes an audit finding. Each change is costed so you see the saving and the risk it removes.
We set the baseline you carry into every renewal and audit, and review it as Microsoft changes SKUs and terms. When a deal or a compliance review lands, you start from strength, supported by our Microsoft audit defense service.
Most organisations respond to Microsoft compliance risk by buying more than they need, on the theory that surplus licences are safer than a shortfall. That instinct is expensive and usually wrong. A clean entitlement baseline mapped to the Microsoft Product Terms tells you exactly where you stand, which means you can hold the licences you need and drop the ones you do not without fear of a Software Asset Management surprise.
When Microsoft does open a SAM engagement or a formal audit, the buyers who suffer are the ones reconstructing their position under deadline. The buyers who do well already know their numbers. Our Microsoft licensing experts keep you in the second group, and where a review turns adversarial we coordinate directly with our audit team. Procurement leaders comparing advisers can review the top software license expert firms, then book a 30 minute call to scope a review of your own estate.
We work with CIOs, IT asset managers, heads of procurement and CFOs who want a Microsoft licensing position they can defend to a board and to an auditor on the same day. Some engage us for a one-time optimization review before a renewal. Others retain us to hold the baseline year round as headcount, acquisitions and new Microsoft SKUs change the picture. Software Assurance is a recurring theme. Its benefits, from License Mobility to planning services and step-up rights, are worth real money when used and pure cost when left dormant. We track which benefits you are entitled to under the Microsoft Product Terms and make sure you actually draw on them. Every engagement is fixed fee with no contingency tied to your spend, so the advice stays honest and the savings stay with you.
The same handful of errors recur across estates of every size. The most expensive is blanket E5. Organisations buy E5 for everyone to simplify procurement, then pay the premium for security and compliance features that a fraction of users ever touch. We split the estate by role and keep E5 only where it earns its place, holding the rest on E3 or the F series.
The second is duplicate security and management tooling. Microsoft 365 E5 already includes Defender, Purview and Entra capabilities that many buyers also pay third parties to provide. We map the overlap and let you retire whichever side costs more, rather than funding both for years.
The third is on-prem drift. Windows Server and SQL Server estates change as virtualisation hosts are added and moved, and licences that were compliant at purchase quietly fall out of line. Without Software Assurance, those licences cannot follow a workload to a new host, which is a common audit trigger. We reconcile the deployment to the entitlement before Microsoft does.
The fourth is Copilot bought ahead of adoption. The seats are easy to buy and slow to use, and the prerequisite can drag the wider estate toward E5. We stage the rollout and hold the prerequisite line. Each of these is a recurring saving, not a one-off, which is why a standing licensing advisory pays for itself between renewals.
