Manufacturing Costing & Inventory Management System is a comprehensive, formula-driven business management solution designed for manufacturing organizations that need integrated control over procurement, inventory, production, costing, sales, and financial reporting in Microsoft Excel.
The workbook provides an end-to-end manufacturing workflow, starting with master data and bill of materials (BOM), followed by purchase requisitions, purchase orders, goods receipt, raw material inventory, material issues, production orders, batch manufacturing records, labour costing, factory overhead absorption, finished goods receipt, sales, and financial reporting. The workflow is designed so that transactions flow through the system in sequence and the resulting inventory, costing, financial statements, and dashboards update through the workbook's calculation engine.
The inventory module supports perpetual inventory management with weighted average costing, while FIFO valuation is calculated in parallel. The system also provides inventory ageing, ABC analysis, stock alerts, work in progress, finished goods inventory, and cost of goods manufactured information.
The production and batch costing module brings together material cost, direct labour, machine-related overhead, labour-based overhead, and facility-based overhead to calculate total batch cost and cost per accepted unit. The workbook uses three overhead pools with different allocation bases, allowing manufacturing costs to be absorbed systematically across production batches.
The solution also includes five management dashboards covering executive performance, inventory, production, cost, and sales. These dashboards provide visibility into revenue, profitability, inventory values, production output, yields, cost structure, and other operational indicators.
Financial reporting includes the manufacturing account, cost of goods manufactured, cost of goods sold, income statement, inventory information, and reconciliation checks. The workbook also includes a validation and exception-reporting module designed to identify issues such as negative stock, unknown item or supplier codes, zero-cost material issues, duplicate transaction keys, low production yields, open work in progress, dead stock, and overhead lines without an allocation basis.
Professional printable forms are included for key transactions such as goods receipt notes, material issue vouchers, batch cost sheets, and sales invoices. The workbook also contains documentation covering the quick-start process, FAQs, troubleshooting, best practices, and change history.
The system is formula driven and contains no VBA or macro code. It is designed to work with Microsoft Excel 2016 and later, including Excel 2019, 2021, and 365.
This solution is particularly useful for manufacturing businesses, accountants, finance teams, costing professionals, inventory managers, production managers, and business owners who want a structured Excel-based system for connecting operational transactions with costing, inventory control, and financial reporting.
The workbook is fully customizable so users can replace the sample master data, company settings, fiscal dates, policies, warehouses, products, suppliers, customers, and other business-specific information with their own data.
