We have ovatu as our booking system and have all our stock listed. When we sell something it gets deducted. We occasionally have a mishap but it's been brilliant. For salon use products, we keep everything in certain places, so wax, strips etc all together, tissues all together and so on so it's easy to see if you're running low. We occasionally keep bits in our rooms but it's fairly straightforward.
The other thing that we have is 'One note' on all our ipads, main computer and I even have it on my phone. We add to this what's needed, so there's a section for ellisons for wax etc, one for environ, one for HD brows and so on. It's been fab as you can be in a treatment and add to the list - you can be in the car and add to the list. And if you pass the wholesalers, you have the list!
I have a lot of things that don't make the boat go faster but they make the trip a lot more fun x
