I'm trying to create a new application in my account with apple developer but it doesn't appear in the list of applications and I can't do it or upload it via XCode. I receive a message that the bundleId already exists, but the bundleId is in my own account.

I'm developing an application in which companies register to expose their services, products and contacts. On the other hand, customers can search and find companies for free and make contact. Here's the detail: to publish your data in the app, the company needs to pay. My question is whether I'm allowed to implement a payment through an external gateway, as I'm going to launch a web version in the near future.
