How to Manage Inventory and COGS for Singapore Online Sellers

As a small business owner in Singapore, managing inventory and calculating the cost of goods sold (COGS) efficiently is crucial for maximising profitability. In a competitive online marketplace, adopting effective strategies can significantly impact your business success. Here’s a practical guide to help you manage inventory and COGS effectively.

1. Inventory Management Strategies

Managing Inventory effectively involves:

• Utilise Inventory Management Software: Implementing tools like QuickBooks or other e-commerce platforms helps automate inventory tracking, integrate sales data, and prevent overselling.
• Conduct Regular Audits: Regular audits ensure that physical stock matches recorded inventory, reducing discrepancies and losses.
• Implement Demand Planning: Use historical sales data, seasonal trends, and promotional activities to forecast demand accurately. This helps in optimising stock levels and mitigating the risk of stockouts.
• Establish Reorder Points: Set automated reorder points based on sales velocity to maintain a balanced inventory. This approach helps avoid both excess stock and shortages.
• Apply ABC Analysis: Categorise inventory into A, B, and C classes based on revenue contribution. Focus on ensuring that high-value items (A) are always in stock while managing lower-value items (C) more flexibly.

Example: A fashion retailer in Singapore utilises inventory software and conducts regular audits to efficiently manage stock levels, reducing excess inventory and boosting sales.

2. Calculating COGS

Accurately calculating COGS for Singapore Online Sellers involves:

• Calculate COGS: Use the formula: COGS = (Beginning Inventory + Purchases) – Ending Inventory. This formula is essential for determining gross profit and setting pricing strategies.
• Include All Relevant Costs: Ensure that COGS includes all direct costs such as materials, labour, and overheads for a comprehensive profitability analysis.
• Monitor Profit Margins: Regularly review how COGS impacts profit margins. Adjust pricing strategies as needed to maximise profitability.
• Choose Appropriate Valuation Methods: Select an inventory valuation method (FIFO, LIFO, or WAC) that aligns with your financial goals. FIFO, for example, can be advantageous in rising price environments by matching older, lower-cost inventory with current revenues.

Example: An electronics store in Singapore applies the FIFO method for inventory valuation, improving tax efficiency and financial reporting.
