Stock That Sleeps Is Capital That Is Locked
Stock sitting on a shelf is not a passive asset. It actively costs money every day: warehouse space, working capital tied up at the prevailing interest rate, the risk of damage or obsolescence, and the labor cost of counting it at year end. This book is for business owners who have looked at a large inventory figure on their balance sheet while the bank account felt tight, and never had a clear explanation for why.
This book was originally written in Bahasa Indonesia for Indonesian operators. Examples, regulations, currency (Rupiah), and institutional references reflect Indonesian context. The frameworks, diagnostics, ratios, and operator habits described apply broadly to small and mid-sized businesses in other emerging markets and to many developed-market SME settings as well.
The central argument: three decisions govern whether inventory becomes a tool or a trap. How much to order. When to reorder. When to release stock that is no longer moving. All three can be made from a single data source that most businesses already have: per-SKU sales records maintained consistently. No expensive software required. A spreadsheet filled with discipline produces enough data to calculate Economic Order Quantity, set a reorder point calibrated to actual lead times, and build a slow-stock release policy with clear time thresholds and documented discount logic.
What you'll find
- Economic Order Quantity: the formula for the order size that minimizes total inventory cost, calculated from your own sales data
- How to set a reorder point tied to actual supplier lead time, not stock levels that feel comfortable
- Total inventory carrying cost: the full calculation of what stacked stock costs in working capital per month, beyond the purchase price
- How to build a slow-stock release policy with written time thresholds and discount authorization levels
- How to compare a vendor's bulk-order discount against the actual carrying cost of holding the additional inventory
- ABC analysis for identifying which SKUs deserve the most attention in any stock review
- Inventory documentation standards that hold up under external audit or investor due diligence
Who this is for
- Small-business owners who have placed large orders because a vendor offered a discount, without calculating the carrying cost of holding the extra stock for three or four months
- Mid-cap directors managing multiple warehouses whose reorder points have not been updated since the business was half its current size
- Pre-IPO teams that need per-SKU inventory records clean enough to survive a due diligence review
