When you open a Microsoft account for a new company, they do a lookup to figure out your area of activity and if you're a good match you get contacted by a sales representative asking you if you want to become an Azure re-seller. Basically for services you sell to third parties you get Azure credits meaning your Azure usage is "free", and your clients pay the premium. I know this because I used to work for a company that did this, and from personal experience when starting a company.

Edit: Here it a tip; if you see a "Microsoft partner <TIER> Cloud Platform" badge on a outsourcers website stay away.
