Honestly, I dont have tons of experience. I do know what Im talking about, and understand how it all works, and have a system in place. I have several accounts now, so I feel confident. But when I started brand new, I would just say flat out " Im new at this, so please bear with me while I learn". And everyone was great about it. I did risk that they wouldnt be understanding, but Im an artist, they know that- and if they couldnt handle me learning the business aspect, then they could go fry an egg. But I was lucky, and everyone I work with is amazing.
