Hello, Our company (ORDER SYSTEMS FOR COMMUNICATIONS AND INFORMATION TECHNOLOGY CO.) is a SaaS provider. We develop apps for clients, but we are not the owner of the business (جباتي وكرك | Chapati & Karak). We already submitted an official authorization letter, fully signed and stamped by the business owner, confirming our permission to build and publish the app — but it was still rejected. The client does not have an Apple Developer account, which is why we are submitting the app on their behalf through our platform. Could you please clarify: What exact documentation is required in this SaaS case? Is a signed and stamped authorization letter never acceptable? Do you require the client to open their own Apple Developer account even though they are using a SaaS system? Thank you.
