With most of our clients, a lot of capital is tied up in stock and not having enough stock will negatively impact customer loyalty. So you need an adequate safety stock level.
So one of the common used methods by our clients for stock reordering is replenishment, it is not my favourite, which is using the AI in our software (the Focus figure), but it is popular. What happens is that you get the computer to order so many days of sales. Its advantage is that it is conceptually simple, makes sense and is very easy to use.
Give it a try and see how you like it.
