No guesswork, no surprise true-ups, and no navigating Microsoft's licensing complexity on your own. [![Book a Consult](https://no-cache.hubspot.com/cta/default/21510856/1af80677-21d0-49c8-9c3c-e50f884e4507.png)](https://cta-redirect.hubspot.com/cta/redirect/21510856/1af80677-21d0-49c8-9c3c-e50f884e4507) ![microsoftlicensingservices-2-1](https://www.c4communications.com/hubfs/site-files/Microsoft%20Licensing%20Services/microsoftlicensingservices-2-1.png "microsoftlicensingservices-2-1") ## A Different Kind of Microsoft Relationship Most organizations either manage Microsoft licensing themselves – reactively, at renewal time – or rely on a reseller who completed the transaction and moved on. Neither approach gives you the ongoing oversight that Microsoft's licensing model actually requires. As your CSP of record, C4 manages your Microsoft environment as a continuous service: monitoring utilization, right-sizing your subscription mix, managing renewals proactively, and ensuring your licensing posture stays aligned with how your business is actually using the platform. ## What CSP-Led Licensing Management Delivers When C4 serves as your CSP of record, Microsoft licensing becomes a managed, optimized service – not an annual scramble. ![icon-microsoftlicensing-3-1](https://www.c4communications.com/hubfs/site-files/Microsoft%20Licensing%20Services/icon-microsoftlicensing-3-1.svg) ### Optimization We continuously monitor seat utilization, product mix, and feature usage across your Microsoft environment – identifying redundancies, unused licenses, and opportunities to right-size your subscription before renewal. ![icon-microsoftlicensing-3-2](https://www.c4communications.com/hubfs/site-files/Microsoft%20Licensing%20Services/icon-microsoftlicensing-3-2.svg) ### Lifecycle Management From initial deployment through user additions, role changes, and offboarding, we manage the full lifecycle of your Microsoft licensing – so your environment stays current and your spend stays accurate. ![icon-microsoftlicensing-3-3](https://www.c4communications.com/hubfs/site-files/Microsoft%20Licensing%20Services/icon-microsoftlicensing-3-3.svg) ### Renewal & Cost Control We manage your renewal timeline proactively – benchmarking your current pricing, identifying applicable promotions, and ensuring you're never auto-renewed into a contract that no longer fits your needs. ## What We Manage on Your Behalf Microsoft's licensing portfolio spans productivity, security, voice, and cloud infrastructure. We bring the same independent advisory approach to licensing that we apply across the rest of your technology stack. - [Microsoft 365](https://www.c4communications.com/services/microsoft-licensing#tab1) - [Azure & Cloud Services](https://www.c4communications.com/services/microsoft-licensing#tab2) - [Security & Compliance Add-Ons](https://www.c4communications.com/services/microsoft-licensing#tab3) [Microsoft 365](https://www.c4communications.com/services/microsoft-licensing#tab1) ![icon-microsoftlicensing-4-1](https://www.c4communications.com/hubfs/site-files/Microsoft%20Licensing%20Services/icon-microsoftlicensing-4-1.svg) #### Microsoft 365 We manage your M365 subscription across all plans and tiers – optimizing seat counts, ensuring the right users have the right licenses, and eliminating the over-provisioning that accumulates when licensing isn't actively managed.

We help you right-size your Azure environment and integrate cloud licensing decisions into your broader infrastructure strategy.

We help you identify which add-ons are earning their place and which can be consolidated. ## Your Path to the Right Solutions Here’s how we simplify the process of choosing the best-fit cloud technology. Step 1 ### Evaluate You have a problem. We help evaluate providers. Step 2 ### Recommend We recommend the right provider.
