Starting soon as admin/ invoice person at small company - previous lady handed over to me, but it was chaotic, I asked as many questions as I could but she wasn't great at explaining. she's retiring and wants to go soon, but around for questions, for a while! Boss has no computer literacy and previous lady knows everything. Any tips on how to deal with this - feel like I've got this business in my hands and don't know what I'm going to be doing!
