There are two working tabs. On Products you add each item once. On Movements you log stock coming In (deliveries) and going Out (sales), picking the product from a dropdown. Back on Products, stock on hand, stock value and potential profit update themselves via SUMIFS, and any item at or below its reorder level turns red — so your reorder list is just the red rows.
The Dashboard summarises the whole shop: number of products, total stock value, how many items are low or out of stock, and your potential profit if everything sells. It opens in Excel or Google Sheets.
When you'd rather stock updated itself as you sell, Biashara Yangu records sales and keeps your books automatically — so your figures are always current without a stock-count.
