Bling Inventory Integration

One demand I get from a lot of e-commerce clients is a stock graph, from Bling, in three different situations: products sold (quantity and value), products in stock (quantity and value) and a third graph with the forecast of the average stock period (Quantity of product / by number of days -> Current stock / average sales for the days). This is something I get a lot of requests for, so that they can predict which products they should prioritize when buying.
