There are multiple ways you can buy Azure depending on your needs. Microsoft offers a simple, pay-as-you-go option with no upfront commitment required and you only pay for what you use. If you’d prefer to budget for a year or multiple years, Azure Monetary Commitment allows Enterprise Agreement customers to commit upfront and have both consumption services and Azure Reserved VM Instances deduct from Monetary Commitment.
Here at FD we offer the 2-tier CSP program, where end customers will purchase from a partner, who purchases from us as the distributor. On CSP there are some important aspects to take note, Microsoft bill run is from the 18th to the 17th of every month. We will provide the estimates based on a request from our partners. We also provide a detailed summary of your Azure usage at the end of the month in the form of an itemised bill.
