Hi so I have a few people that rent chairs from me and I’m struggling with stock control! So basically I buy all the colour stock as the brand we use you can’t buy from wholesale.. at the end of the week they total up what they have used and pay me for it! Only this week I noticed one of them had a few things missing off what they said they had used compared to what I had seen them use. I don’t always have time to watch and count myself what they are using being a busy stylist myself. Any ideas how I can manage this better?
