Inventory is but cash in stock. Unsold inventory or unplanned raw materials only eat in to the bottomline. SAP Business One Inventory ERP is a comprehensive stock and warehouse management module that tracks real-time inventory status across warehouses to ensure products are sourced and produced on a just-in-time basis. Neither too early nor too late. This helps not only in managing cash flows better by controlling wastage and excess stocking but also in reaching the products to the market on time.
