What it does
For every product, a sales forecast, the stock level at which to reorder, and how many units to buy. It tells you what runs out before the next delivery lands. It reads your Shopify orders and stock. It works out how fast each item sells, adjusts for trends and optional seasonality, and projects demand over your chosen window. Then it applies your supplier lead time and a safety buffer to set the reorder point. The suggested purchase quantity covers demand until the next order arrives. You can narrow it to one supplier or only the items at risk of stocking out. It reads data only and changes nothing.
