Cloud Solution Provider (CSP) agreement is the modern approach to managing your Microsoft cloud licenses. As compared to the traditional Enterprise Agreement (EA), the CSP model provides greater flexibility and support to your business.
Providing you direct control over adding and removing licenses at any time, so that you are paying only for what you need. This comes with increased flexibility on your billing frequency while providing additional Microsoft partner support.
Finally you are invoiced directly from your CSP provider, allowing for one easy bill to manage.
