When costs surge but selling prices haven't risen yet (or can't keep up), what happens is "paper profits exist but cash is gone" — this is the Cash Flow Gap that can collapse a business even with high sales. According to Bank of Thailand data from 2025, over 40% of Thai SMEs face liquidity problems despite no decline in sales. This number is expected to increase after the 2026 oil crisis pushes all costs higher. This article teaches systematic cash flow management to help businesses survive when costs keep rising.
Quick Summary: Costs up 20% but selling prices only up 10% + customers paying slower + suppliers demanding faster payment = Cash Flow stalls. This article teaches systematic cash flow management during the oil crisis, from Working Capital Management and 13-Week Cash Flow Forecast to 5 techniques you can implement immediately.

Why Does Cash Flow Stall During the Oil Crisis?
Many wonder why sales are good but cash is short. The answer lies in the "timing" of cash inflows and outflows that changes during a crisis. Costs must be paid first but customer payments come later — this gap is the Cash Flow Gap that keeps widening.
| Cause | Details | Impact on Cash Flow |
|---|---|---|
| 1. Costs Rise Before Selling Prices | Suppliers raise prices immediately but businesses need time to adjust selling prices | Cash outflow increases immediately while cash inflow stays the same |
| 2. Suppliers Demand Cash / Shorter Terms | From Credit 60 days down to 30 days or Cash on Delivery | Cash must be paid 30 days sooner |
| 3. Safety Stock Increases = Tied-Up Capital | Fear of shortages leads to ordering more stock at higher prices | Capital tied up in inventory increases 20-50% |
| 4. Customers Delay Payments | Customers are also affected, so they extend payment timelines | Cash inflow delayed 15-30 days |
| 5. Shipping Costs Paid in Cash Immediately | Vehicle, shipping, and fuel costs are mostly Cash Payments | Cash disappears before products are sold |
Example Numbers: Working Capital Cycle Before vs After Crisis
| Item | Before Crisis | After Crisis | Change |
|---|---|---|---|
| Monthly Sales | 10 million baht | 10.5 million baht (partial price increase) | +5% |
| Monthly Costs | 7.5 million baht | 9 million baht | +20% |
| Gross Profit | 2.5 million baht (25%) | 1.5 million baht (14.3%) | -40% |
| Average Receivables (AR) | 10 million baht | 14 million baht (slower payments) | +40% |
| Average Inventory | 5 million baht | 7.5 million baht (stock more expensive + increased) | +50% |
As you can see, even though sales increased 5%, the cash tied up in receivables and inventory grew enormously. Paper profits still exist, but real cash has vanished — a situation similar to the budget overrun problem many organizations face.
Working Capital Management — Formulas Executives Must Know
Managing Cash Flow starts with understanding Working Capital, which has the following formulas:
Working Capital Formula:
Working Capital = AR (Receivables) + Inventory - AP (Payables)
Cash Conversion Cycle (CCC):
CCC = DSO + DIO - DPO
DSO = Days Sales Outstanding (average days to collect receivables) | DIO = Days Inventory Outstanding (average days inventory sits) | DPO = Days Payable Outstanding (average days to pay suppliers)
The higher the CCC = the longer cash is tied up = the tighter Cash Flow gets. Let's see how the oil crisis increases the CCC:
| Metric | Before Crisis | After Crisis | Change |
|---|---|---|---|
| DSO (Collecting Receivables) | 30 days | 40 days | +10 days |
| DIO (Inventory Days) | 25 days | 40 days | +15 days |
| DPO (Paying Suppliers) | 10 days (Credit 60 days) | 15 days (reduced to Credit 30 days) | +5 days |
| CCC | 45 days | 65 days | +20 days |
Impact: CCC increased by 20 days, meaning approximately 6 million baht more cash is tied up (average daily sales of 300,000 baht x 20 days). For a business with 10 million baht monthly sales, without cash reserves, the business may reach a point where it cannot pay Suppliers even though the P&L still shows profit.
5 Techniques for Managing Cash Flow During a Crisis
Technique 1: Accelerate Receivables Collection (AR Management)
- Early Payment Discount: Offer 2% discount for payment within 10 days (2/10 Net 30) — lose 2% but get cash 20 days sooner.
- Weekly follow-up: Send Statements to customers weekly, not just at month-end.
- Prioritize: Focus on Top 20 debtors who account for 80% of outstanding balances.
- Run Aging Analysis: Segment receivables by age 30/60/90/120+ days — anything over 90 days must be escalated immediately.
Technique 2: Renegotiate Credit Terms with Suppliers
- Request Extended Credit Terms: From 30 days to 60 days by offering increased order volumes or long-term contracts.
- Partial payment first: Negotiate paying 50% on delivery and 50% within 30 days instead of full payment upfront.
- Find alternative Suppliers: Use them as bargaining power — if Supplier A pushes on Credit Terms, get quotes from B and C for comparison.
Technique 3: Reduce Unnecessary Inventory
- ABC Analysis: Item A (80% of sales) — keep full stock / Item C (5% of sales) — reduce stock to minimum.
- Sell stale inventory: Items sitting over 90 days — discount and sell to convert to cash. A small loss is better than tied-up capital.
- Just-in-Time ordering: Reduce Lead Time with Suppliers to order more frequently in smaller quantities — reducing capital tied up in inventory, which relates to Chart of Accounts principles for accurate inventory recording.
Technique 4: Cut Costs Where Possible
- Unnecessary expenses: Review Subscriptions, rent, and underutilized services.
- Defer non-urgent projects: Postpone non-critical CAPEX to preserve working capital.
- Reduce overtime costs: Improve production planning efficiency and eliminate unnecessary OT.
Technique 5: Prepare Backup Credit Lines
- Emergency credit facility (Revolving Credit): Secure the credit line in advance — no need to draw it down, but it's ready when needed.
- Factoring: Sell trade receivables to a bank, receive 80-90% cash immediately (1-3% fee).
- Trade Finance: Use L/C or Trust Receipt for imports to extend payment timelines.
| Technique | Immediate Results (1-2 weeks) | Long-term Results (1-3 months) |
|---|---|---|
| Accelerate AR Collection | Receive some cash back faster | DSO reduced by 10-15 days |
| Negotiate Credit Terms | Delay cash outflow immediately | DPO increased by 15-30 days |
| ลด Inventory | Sell stale stock and recover cash | DIO reduced by 10-20 days |
| Cut Costs | Reduce cash outflow immediately | Save 5-15% of OPEX |
| Backup Credit Line | Cash ready to use immediately | Reduce liquidity risk |
Cash Flow Forecast — Do It Weekly, Not Monthly
In normal times, a monthly Cash Flow Forecast is sufficient. But during a crisis, the 13-Week Cash Flow Forecast is an essential tool — because it helps you see when cash will run out before it actually does.
Example: 13-Week Cash Flow Forecast (First 4 Weeks)
| Item | Week 1 | Week 2 | Week 3 | Week 4 |
|---|---|---|---|---|
| Cash Inflow | ||||
| Customer Payments Received | 2,500,000 | 1,800,000 | 2,200,000 | 3,000,000 |
| Other Revenue | 50,000 | 50,000 | 50,000 | 50,000 |
| Total Cash Inflow | 2,550,000 | 1,850,000 | 2,250,000 | 3,050,000 |
| Cash Outflow | ||||
| Supplier Payments | 1,800,000 | 2,200,000 | 1,500,000 | 2,800,000 |
| Salaries + Benefits | — | — | — | 1,500,000 |
| Transport + Energy Costs | 350,000 | 350,000 | 400,000 | 400,000 |
| Other Expenses | 200,000 | 150,000 | 200,000 | 150,000 |
| Total Cash Outflow | 2,350,000 | 2,700,000 | 2,100,000 | 4,850,000 |
| Net Cash (Inflow - Outflow) | +200,000 | -850,000 | +150,000 | -1,800,000 |
| Cumulative Balance | 3,200,000 | 2,350,000 | 2,500,000 | 700,000 |
Do it weekly, not monthly! The table shows that by Week 4, only 700,000 baht remains — which may not be enough for emergency expenses. A monthly Forecast wouldn't reveal this critical point until it's too late. During a crisis, create a 13-Week Forecast and update it every week.
Exchange Rates — A Compounding Factor
Beyond surging oil costs, exchange rates are another factor that compounds Cash Flow pressure. When the baht weakens, import costs rise immediately + USD-denominated debts become more expensive. SCB EIC estimates the baht may continue weakening due to trade balance deterioration from higher oil import costs.
| Baht Depreciation (per 1 USD) | Import Cost Increase | Impact on Businesses Importing 5 Million USD/Year |
|---|---|---|
| 34 → 35 baht (+1 baht) | +2.9% | Cost increase of 5 million baht/year |
| 34 → 36 baht (+2 baht) | +5.9% | Cost increase of 10 million baht/year |
| 34 → 38 baht (+4 baht) | +11.8% | Cost increase of 20 million baht/year |
Currency Hedging Techniques
- Forward Contract: Lock the exchange rate in advance, e.g., agree to buy USD at 35 baht in 3 months — even if the baht weakens to 38, you still buy at 35.
- Natural Hedge: If you also earn revenue in USD, use USD revenue to directly pay USD costs without converting to baht.
- Multiple currencies: Diversify imports from multiple countries instead of relying solely on USD.
Managing exchange rate risk is part of enterprise risk management that executives must plan in advance.
How Does ERP Help Manage Cash Flow?
Effective Cash Flow management requires data from AR, AP, Inventory, and Bank connected in a single system — which is what ERP does better than using separate Excel files per department, as a comprehensive accounting system provides a complete financial overview.
| ERP Module | How It Helps Cash Flow | Data Obtained |
|---|---|---|
| AR Module | Automated receivables tracking with pre-due-date alerts | Aging Report, DSO, list of overdue receivables |
| AP Module | Plan payables by priority | Payment Schedule, DPO, Cash Requirement |
| Cash Management | View real-time cash balances across all accounts | Bank Balance, Cash Position, Fund Transfer |
| Financial Reporting | Automated Cash Flow Statement + Projection generation | Cash Flow Report, Working Capital Dashboard |
Note: Saeree ERP includes AR, AP, Cash Management, and Financial Reporting modules that generate Cash Flow Reports from real system data instantly. Saeree ERP is currently developing an AI Assistant in the Training phase — Predictive Cash Flow is not yet available, but the existing system data is sufficient for creating a 13-Week Forecast manually.
What Else Should Executives Monitor?
Cash Flow is just one part of the big picture. Executives need to monitor other aspects alongside it:
