Navigating Microsoft's various software agreements can be a bit overwhelming, but it's essential to ensure you're getting the best deal for your organisation's needs. Let's break down three of the most common agreements:

  • Enterprise Agreement (EA)
  • Cloud Solution Provider (CSP)
  • Microsoft Customer Agreement for Enterprise (MCA-E)

Each of these offers unique features, terms, and benefits tailored to different organisational requirements. Below is a detailed comparison of EA, CSP, and MCA-E to help IT and procurement leaders make informed decisions about the right licensing choice for your business. (Spoiler alert: CSP might just be the best fit for many organisations.)
