You can know the movements of your products, accessing the product tab > Stock tab > Show history. In this section you can filter by start date and end date.
The graph shows a first overview or perspective of the product stock, based on the increase or decrease of the units according to the generated documents.
Under the graph you will find more detailed information, such as the date and time when the movement took place; the origin and destination in case of having several warehouses; the actual stock prior to the movement; the units added or subtracted depending on the document that was generated; the type of movement according to document creation or manual stock editing; the employee who performed it and the reference of the document in which the movement is located.
All this information can be exported in an Excel file in case you need it.
