A large account reseller (LAR) is a reseller or distributor that a software vendor has authorized to sell and administer licenses for customers within a specified licensing channel. The term is most closely tied to Microsoft volume licensing. What makes a company an LAR is the vendor’s authorization and the licensing program it works under, not the size of the customers it sells to.
What the term means
In plain language, an LAR is a vendor-approved intermediary. The vendor, in the sources reviewed, Microsoft, permits the reseller to distribute licenses to customers under a named agreement or program. Two conditions define the role: the vendor’s permission, and a specified licensing channel. A company that simply sells software to a large enterprise is not an LAR unless it holds that authorization for that program.
Where the definition comes from
The clearest formal wording comes from older Microsoft contracts and program guides. Use the table below to separate historical definitions from current usage.
| Source | Date or status | What it says about an LAR |
|---|---|---|
| Microsoft Select Master Agreement (Puerto Rico S.O.), reproduced in a Government of Puerto Rico document | Agreement dated 1996; historical contract definition | An LAR is “any distributor or reseller which Microsoft or one of its affiliates permits to distribute Licenses to Enrolling Customers.” |
| Microsoft Open License guide glossary | Historical program guide with dates in 2001–2002 | Describes an authorized reseller or distributor permitted to distribute agreements to customers. This is program-era wording, not a current universal definition. |
| Microsoft “Licensing Documents: License Mobility” guidance | Current guidance, checked 7 October 2026 | Uses “Large Account Reseller or other partner that sold you the Microsoft licenses” as a channel-partner label relevant to license verification. |
Read together, these sources show a consistent core: authorization first, then a defined distribution role. They do not show a single, universal legal category that applies to every vendor and every market.
#1 Best Overall
- Microsoft Surface Book 2 Features a 7th generation Intel Dual Core i5 Processor, 256 GB of storage, 8 GB RAM, and up to 17 hours of video playback
- Includes an Intel HD Graphics 620 integrated GPU
- The fastest Surface Book yet, with 2x more power
- Vibrant PixelSense Display: now available with an improved 13.5in touchscreen
How the label is used today
Current Microsoft guidance treats LAR as a partner label that matters during license verification. It is not presented as a general description of any large-company reseller. Verification records typically ask for the channel partner that sold the licenses, along with:
- The agreement type.
- The agreement or authorization number.
- The applicable enrollment or license number.
Procurement use is broader. Exelon’s supplier guidance, checked 7 October 2026, lists LAR-provided software within its IT Software procurement category. That confirms the term appears in buyer-side purchasing, but a listed category does not by itself prove a formal designation exists for a given reseller.
Rank #2
- Most powerful Surface laptop yet, with quad-core powered, 10th Gen Intel Core processors. More than 50% faster than Surface Book 2 13.5”.
- Fastest graphics on Surface, powered by NVIDIA GTX GeForce GPU. 40% more graphics performance than Surface Book 2 13.5".
- Power when you need it. Up to 15.5 hours battery life[1] — plus improved standby that extends battery life when you’re away.
- Robust laptop, powerful tablet, and portable studio in one.
- The connections you need, including USB-A, USB-C, and full-size SD card slot.
What an LAR typically does
The scope of an LAR’s work is set by its contract, not by the label. A public-sector example, the Arizona Department of Administration State Procurement Office’s WSCA Software Value-Added Reseller solicitation and statement of work, shows the kinds of services a buyer may contract for:
Recommended Free Tools
- License purchasing and management.
- Maintenance and support.
- Cost negotiation.
- Basic installation assistance.
- License tracking.
That same specification says a reseller may buy directly from a publisher or through a distributor, and should honour existing volume or enterprise license agreements. Treat these as examples of what a contract can require. They are not a guarantee that every LAR offers each service, and the procurement example is a government contract rather than a Microsoft rule.

A historical example of the designation
Wipro Arabia Limited announced on 22 August 2010 that it had been accorded Microsoft Large Account Reseller partner status in Saudi Arabia. Durga Prasad, GM and Head of Business Operations at Wipro Arabia, said: “We are excited about Wipro being selected as the LAR partner for Microsoft. Through this partnership, we will now be able to increase our competitiveness in providing customer-centric solutions on Microsoft platform to our customers in the Kingdom.” This is a company announcement about a single partnership in 2010. It shows how the designation was publicised at the time, not how customers fared.
Is LAR status current everywhere?
This is the point most likely to cause confusion. The sources reviewed establish that LAR is a term in Microsoft licensing documents, both historical and current. They do not establish whether Microsoft grants a formal LAR designation in every country and licensing program today. Treat the label as something to verify for your own market and agreement, not something to assume.
How to check a reseller’s authority
Before relying on a reseller, confirm the following. These checks follow from the licensing guidance and procurement examples above; they are not a ranking of resellers.
- Authorization for your exact country and program. Ask whether the reseller is authorized for the licensing program your agreement uses, not just for Microsoft products in general.
- Ability to work with your agreement. Confirm it can honour your existing volume or enterprise agreement and supply the agreement number that verification requires.
- Scope of administration and support. Get written detail on license administration, tracking, maintenance and installation help.
- Reporting. Ask what license reports you will receive and how often.
- Quoted commercial terms. Compare quotes against the same scope of service, not on headline price alone.
Numbers and market size
No dependable count of how many LARs exist, or any market-share figure for them, is established by the sources reviewed. Be cautious with any article or vendor page that quotes one without a named, dated source.
