What is a Microsoft CSP partner?

CSP stands for Cloud Solution Provider, Microsoft's partner model. Instead of buying directly from Microsoft, you get licences, billing and support through a partner. The product does not change: same Microsoft 365, same cloud. What changes is who picks up the phone when something breaks.

Is Microsoft 365 more expensive through a CSP partner?

Usually not. List prices are comparable, and you get one invoice instead of a card charge, plus monthly adjustment of licence counts. The difference is in support and setup, not in price.

Business Basic, Standard or Premium: what does a small business need?

Basic covers web and mobile without installed Office, Standard adds the desktop apps, Premium adds security and device management. Two questions decide it: do your people work in the browser or in installed Office, and how sensitive is the data. Sensitive data and mobile devices argue for Premium.

Is Microsoft 365 securely configured out of the box?

No. Multi-factor authentication, Defender policies and access rules have to be set up deliberately. The most common damage in small businesses is not a spectacular attack, it is a hijacked mailbox without a second factor.

Can I move an existing Microsoft 365 contract to a CSP partner?

Yes. The switch is possible at the end of the current billing period, and mailboxes and data stay untouched. What moves is the contract route, not the tenant.

Microsoft 365 for small businesses: why the CSP route almost always beats the online subscription

Buy Microsoft 365 directly or through a CSP partner? For small businesses the difference matters more than you would think: in support, security and licensing.

“Can we not just buy Microsoft 365 directly with the company card?” I hear this often, and technically the answer is: yes, of course. In practice it is rarely the best idea. Going through a Cloud Solution Provider, CSP for short, usually costs the same or less and gives you noticeably more day to day. Here is the take without the sales pitch.

What CSP actually means

CSP is Microsoft’s partner model. Instead of buying your subscription directly from Microsoft, you get it through a partner who bundles licensing, billing and support. Nothing changes about the product: it is the same Microsoft 365, the same apps, the same cloud. What changes is who picks up the phone when something goes wrong.

The difference day to day

One contact instead of a hold queue. With a direct subscription you land in general Microsoft support. Through CSP you call the partner who knows your business, in your language, without ticket-number ping-pong.
One invoice. Licences, adjustments and support run through a single document instead of a card charge nobody can place.
Scale flexibly. New employee, new licence; someone leaves, licence gone. You adjust it monthly without clicking through Microsoft portals.

The licensing jungle, briefly sorted

Most small businesses need exactly one of three tiers: Business Basic (web and mobile only, no installed Office), Business Standard (with the desktop apps) or Business Premium (plus security and device management). The most common mistake is to book the most expensive blindly, or the cheapest by reflex. Which tier fits depends on two questions: do your people work in the browser or in installed Office, and how sensitive is your data.

Security is not the default

A point that easily gets missed: Microsoft 365 is not automatically configured securely. Multi-factor sign-in, Defender, sensible access rules, all of that has to be set up actively. This is exactly where Business Premium plus a clean initial setup pays off, because the most common damage in small businesses is not the movie-style hacker attack, but a hijacked, poorly protected mailbox.

What you do not need

You do not need enterprise licences, a consulting project running for months, or features nobody ever opens. A clean setup, the right tier per person and a contact who is actually reachable fully cover what most businesses need.

How we do it

We are a Microsoft CSP partner: we procure the licences, set up Microsoft 365 securely and keep supporting it, one partner, one invoice, German-language support. First we look honestly at which tier you really need, instead of selling you the biggest licence.

If you want to know whether the CSP route is cheaper and simpler for you: I will work it out for you with no obligation.
