Microsoft's Services Provider License Agreement, or SPLA, is a licensing model designed specifically for service providers.
The SPLA allows service providers to offer Microsoft products and services to their customers without having to purchase perpetual licenses.
To be eligible for the SPLA, a service provider must be a registered partner with Microsoft.
This agreement is ideal for service providers who want to offer a wide range of Microsoft products and services to their customers without the upfront cost of purchasing perpetual licenses.
The SPLA is a subscription-based model, which means that service providers pay a monthly fee for the licenses they use.
This fee is calculated based on the number of users or devices being served by the service provider.

License Agreement Details
A Microsoft Services Provider License Agreement (SPLA) is an agreement between two parties: an end user and a service provider. It's a licensing structure that allows service providers to offer Microsoft products and services to their customers on a monthly basis.
The license agreement is concluded between the service provider and Microsoft, and the end user "rents" services from the service provider, paying service costs for this. This means the service provider is the licensee, and the end user is not required to purchase the licenses themselves.

Here are the different use rights available under a Microsoft SPLA license agreement:
- Per Subscriber: A Subscriber Access License (SAL) is required for each unique individual user or device that is authorized to access or otherwise use the licensed products.
- Per Processor: Each Processor License allows an unlimited number of users to access the software that is installed on that processor.
- Per Core: Each Core License (CL) allows an unlimited number of users to access the server software installed on the server with a determined number of physical cores.
- Per Guest/Host Licensing Model: The Host/Guest licensing model requires both host licenses and guest licenses.
- Product-Specific Licensing: This model requires specific licensing components for providing a partner-hosted solution to customers.
Use Rights
The use rights of a license agreement are crucial to understanding how you can use the software.
A Subscriber Access License (SAL) is required for each unique individual user or device that is authorized to access or otherwise use the licensed products.
You can license software per Subscriber, which means a separate Server License is not needed. This option is great for small businesses or individuals who only need to use the software on one device.
Here are the different use rights options:
- Per Subscriber: 1 SAL required per unique user or device
- Per Processor: unlimited users can access software installed on that processor
- Per Core: unlimited users can access server software installed on a server with a determined number of physical cores
- Per Guest/Host: both host and guest licenses are required
The Per Processor model is a good option for businesses that need to use the software on multiple devices, but only have one processor.
In the Per Core model, the number of physical cores on the server determines the number of users who can access the software.
The Host/Guest licensing model is more complex, requiring both host licenses for the "host fabric" and guest licenses for the virtual OSEs.

Pricing & Payment
Pricing and payment in SPLA are flexible and predictable, tailored to the needs of service providers and ISVs. Specific pricing details are not publicly disclosed due to their variability and the confidential agreements between Microsoft and service providers.
Service providers set their price towards end customers based on the price list they receive from Microsoft, with potentially an added margin. This is similar to indirect models in Volume Licensing like CSP and MPSA.
The cornerstone of SPLA’s pricing structure is its monthly reporting and payment process, which allows service providers to pay only for the licenses they have actually used or made available to end customers during the preceding month.
Here's a breakdown of the monthly reporting and payment process:
- Usage tracking: Service providers are responsible for tracking their usage of Microsoft products across their services each month.
- Monthly reporting: At the end of each month, service providers submit a usage report to Microsoft or a designated SPLA Reseller.
- Payment: Based on the monthly report, service providers are invoiced for the licenses used.
Payment terms are typically set forth in the SPLA agreement and usually require payment within a specified period after invoicing.
Compliance and Support
Compliance and support are crucial aspects of the Microsoft Services Provider License Agreement (SPLA). Resellers provide invaluable support in understanding and adhering to SPLA terms, reducing the risk of non-compliance and costly audits.
Audit preparation is also a key aspect of compliance. In the event of a Microsoft audit, resellers can offer guidance and support to ensure that the service provider is well-prepared, with all necessary documentation and reporting in place.

Microsoft regularly audits SPLA partners for compliance, with audits typically handled by third-party firms. An audit can review the past several years of usage data to identify any under-reported licenses, and many service providers can expect an audit at least once every 2-3 years.
The audit process involves a formal notice letter, after which the provider usually has 30 days to respond and prepare. Auditors will gather data to calculate what the provider should have reported versus what was reported.
If under-licensing is found to be beyond a small threshold (5% variance), Microsoft will demand back-payment for all unreported licenses at current pricing, plus a 25% penalty. The provider must also pay the auditor’s fees, which can be a painful hit.
To stay compliant, providers require robust asset management and monitoring tools to track every instance and user in near real-time. Regular self-audits and true-ups are also recommended to prevent mistakes in monthly reports.
Here are some key best practices for maintaining compliance:
- Maintain a license usage register
- Document all changes (new deployments, decommissions, client onboarding/offboarding)
- Retrain proof when clients bring their licenses (e.g., License Verification Forms for BYOL scenarios)
By following these best practices and staying on top of compliance, service providers can avoid costly audits and penalties.

How It Works
Microsoft's SPLA licensing program is a three-year agreement that allows service providers to rent Microsoft software on a pay-as-you-go basis for hosting services. This means they only pay for what they use, based on their peak monthly usage.
The agreement involves monthly usage reporting, which helps providers keep track of their usage and avoid overpaying for software they're not using. This reporting feature also helps Microsoft to ensure that providers are in compliance with the agreement.
Providers only pay for what they use, which can be a significant cost savings compared to traditional licensing models. This pay-as-you-go approach can also help providers to better manage their IT budgets and make more informed decisions about their software needs.
The SPLA agreement has a fixed term of three years, after which it can be renewed or terminated. This provides providers with a clear understanding of their licensing obligations and helps them to plan for the future.

Model Explained

The SPLA licensing model is designed to accommodate various hosting scenarios, ensuring service providers can offer Microsoft products in a cost-effective and compliant manner.
There are three primary SPLA licensing models: per user, per processor, and per core. Each model has its applications and advantages.
The per processor model allocates licenses based on the number of processors in the server, making it a good fit for high-density hosting environments.
This model is particularly relevant for legacy applications or when precise user counts are unpredictable.
The per core model is an evolution of the per processor model, designed for modern, multi-core server environments.
Licenses are allocated based on the number of cores in each processor, offering a more granular approach to licensing.
The per core model is well-suited for data-intensive services such as databases and analytics platforms.
Here's a comparison of the per processor and per core models:
Products like SQL Server, BizTalk Server, System Center, Windows Server, and SharePoint (External websites) fall under the per core (or per processor) license category.
Reporting & Payments

SPLA's monthly reporting and payment process is designed to support service providers' scalability and operational flexibility.
Service providers are responsible for tracking their usage of Microsoft products across their services each month.
This includes the number of users accessing a service, the number of processors or cores utilized, and any other metrics relevant to the licensing model chosen.
A monthly report detailing the specific Microsoft products used, the licensing models applied, and the quantity of licenses required must be submitted to Microsoft or a designated SPLA Reseller at the end of each month.
Payment is based on the monthly report, with service providers being invoiced for the licenses used.
Payment terms are typically set forth in the SPLA agreement and usually require payment within a specified period after invoicing.
Here's a breakdown of the monthly reporting process:
- Usage tracking: Service providers track their usage of Microsoft products.
- Monthly reporting: Service providers submit a usage report to Microsoft or a designated SPLA Reseller.
- Payment: Service providers are invoiced for the licenses used based on the monthly report.
Service providers often struggle to report based on actual usage, which can lead to Microsoft conducting audits to verify the accuracy of their reports.
Expert Advice and Tips
As a Microsoft Services Provider License Agreement (SPLA) expert, I've seen firsthand the importance of optimizing license usage to save costs and avoid over-licensing. One of the most effective ways to do this is by working closely with your SPLA reseller.
Customized solutions are key to ensuring service providers utilize the most cost-effective and appropriate licensing options for their specific service offerings. By doing so, resellers can help identify opportunities to optimize license usage and reduce costs.
To ensure transparency, insist on a breakdown of Microsoft licensing costs from your service provider. This will help you understand how SPLA factors into your bill and reveal opportunities for optimization.
Optimizing user counts monthly is a simple yet effective cost saver. Ensure processes are in place to remove or disable unused user accounts before each month's end to prevent paying for Software Assurance Licenses (SALs) that aren't truly needed.
