Who answers enquiries from the end user?
You do, exactly as before.
We stay out of sight and support you technically from behind. The only company your customer sees is yours.
When you have a question, you come straight to us. Even in front of your customer, you can ask us on the spot.
You do not need to worry about losing the relationship. The customer is yours.
