How to become an Authorized Apple reseller

We are an IT integration company that also operates as a computer laboratory and hardware store. We've recently partnered with a new corporate client that relies heavily on Apple products. To better serve this customer and strengthen our ability to sell and promote Apple products, we are interested in becoming an authorized Apple reseller. This would also allow us to register our products in the Apple Business Manager (ABM) before delivering them to the customer. While we understand this is typically possible when purchasing through an authorized reseller, we currently source our products directly from the importer.
