Working Capital That Gets Stuck Is a Decision, Not Fate
Most working capital problems are not problems of how much capital a business has. They are problems of how fast it moves. The capital is there, sitting in receivables that look healthy on the balance sheet, in inventory that appears sufficient in the warehouse, in payables that have not come due yet. Meanwhile the bank account shrinks toward the end of every month, even though last month's sales hit target. This book is for operators asking the question: how much capital is locked inside the operation itself?
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 core diagnostic tool is the Cash Conversion Cycle: the number of days it takes for a rupiah paid to a supplier to come back as cash collected from a customer. Three components determine that number: Days Sales Outstanding (how long customers take to pay), Days Inventory Outstanding (how long goods sit before they move), and Days Payable Outstanding (how long the business takes to pay its own suppliers). Improving any one of these without worsening the others shortens the cash cycle and reduces the working capital the business needs to operate. The book walks through the calculation from basic data and gives the intervention toolkit for each component.
What you'll find
- Cash Conversion Cycle: the full calculation from your existing records, and a worked example across three business types
- Days Sales Outstanding: how to measure it, what benchmark to target, and how to reduce it without harming customer relationships
- Days Inventory Outstanding: the link between slow-moving stock and working capital pressure, with the diagnostic method
- Days Payable Outstanding: how to extend supplier payment terms through better relationships and earlier commitment, not just pressure
- Net Working Capital monitoring: the weekly number that tells you whether the business is building or consuming liquidity
- How to identify which working capital component gives the fastest relief with the least disruption
- Documentation standards for working capital analysis in investor due diligence and bank credit applications
Who this is for
- Small-business owners who see a strong income statement and a thin bank balance every month and cannot connect the two
- Mid-cap directors managing businesses with long project cycles or large inventory positions where cash timing is unpredictable
- Pre-IPO teams that need auditable working capital management methodology for investor review and bank covenant compliance
