Hi Fibonasti
Thanks for your post.
In your Stock Central, you can see a Stock Selling Manager column with various indicators.
I'll leave you here a tutorial where you can find all these indicators explained.
ATUM uses its formula to calculate products that are on restock status. This is the formula: The average sales per day for the last week * Days to reorder.
We calculate the average sales by adding the sales of the product of the last week and dividing by 7.
Hope it answers your query.
Best regards,
Iryna
