MCAKey — Certified Microsoft Partner & Authorized Software Reseller
MCAKey is a US-registered, certified Microsoft Partner and authorized software reseller built for people who need genuine licenses — fast, at fair prices, with real support behind every order. MCAKey serves individual buyers, PC repair shops, IT service providers, and enterprises across the world, delivering legitimate software licenses and backing every sale with human support until the software is running.
Who We Are
MCAKey LLC is a legally registered US company based in Montana, operating as a certified Microsoft Partner and authorized reseller. Our AppSource listing is public and verifiable — no claims without proof.
We sell digital software license keys: Windows, Office, Windows Server, SQL Server, Developer Tools, and more. Every product activates through Microsoft's own servers. No workarounds. No grey-market sourcing. No recycled keys. We are also expanding into antivirus licenses and other software from trusted publishers — Microsoft is our primary focus but not our only one.
We started because buying a legitimate software license online was — and still is — harder than it should be. Too many resellers make big promises and disappear when something goes wrong. We built MCAKey to be the opposite: transparent about what we sell, fast on delivery, and actually available when something needs fixing.

What Sets Us Apart
Certified, Not Claimed
Our Microsoft Partner status is listed on Microsoft AppSource. You can verify it yourself in thirty seconds. That certification defines how we source and sell — it is not a marketing badge.
Support That Does Not Disappear
Every order comes with activation support. If your key does not work, we troubleshoot with you. If the key is faulty, we replace it. We stay in the conversation until the software is running.
Digital-Only, Global Delivery
No physical stock, no shipping, no customs. Your license key arrives by email within 15 minutes of payment. We serve customers globally — the same experience regardless of where you are.
Built for Businesses Too
We work with PC repair shops, IT service providers, and enterprises that need volume licenses, invoices, and a reseller they can rely on consistently. Get in touch before ordering.
Honest Pricing
Our prices reflect real market value. We do not run fake "80% off" promotions to manufacture urgency. What you see is what the key is worth at a fair margin — nothing inflated, nothing hidden.
Microsoft Licensing Expertise
Choosing the right Microsoft license for a business is not always obvious. We offer consulting to help companies pick correctly and stay compliant — before they buy, not after.
Certifications & Partnerships
MCAKey holds certifications from the publishers whose software we sell. These are formal partner relationships — not affiliate badges — that define our sourcing, sales conduct, and support standards.
Microsoft Certified Partner
Microsoft Authorized Reseller

Who We Work With
Individual Users
You need a genuine software license for your personal machine. You want it fast, at a fair price, from a source you can verify. That is exactly what we do.
PC Repair Shops & IT Resellers
You buy licenses regularly and need a supplier that is reliable, invoice-ready, and available when something needs resolving. We have worked with repair shops and IT providers and understand what that relationship needs to look like.
Businesses & Enterprises
You need volume licenses, compliance documentation, and guidance on which products fit your infrastructure. We cover all of this — and our consulting service exists specifically for situations where the licensing question is not straightforward.
Registered, Accountable, Verifiable
MCAKey LLC is registered in Montana, United States at 1001 S. Main St. STE 500, Kalispell, Montana 59901. We are not an anonymous storefront. We operate under US business law, maintain proper business registration, and hold active certifications from the publishers whose products we sell.
If you have ever bought a software license and wondered whether the seller actually exists — we understand that concern. It is a legitimate one in this industry. Our answer is simple: look us up. The company is real, the certifications are real, and the address is verifiable.
