We’ve been working with SmartShop for a year and a half now. What I like is that the process is easy to understand: you receive the account, check the access, and then make the payment. There’s also a dedicated Telegram chat with the team for questions after delivery.
For us, having that ongoing contact is a big part of the service. Apple Developer accounts can come with plenty of practical questions, so it’s useful to have a familiar team to turn to. We appreciate being able to keep working with the same people over time.
