Working Capital Management and Cash Optimization: Maximizing Cash Flow
Master working capital. Manage AR/AP, optimize cash flow, improve efficiency.
Key Takeaways
- Working capital: Cash needed to fund operations (AR + inventory - AP = working capital). Improve: Faster collections (AR), slower payments (AP), less inventory. Example: 100 customers, £1K each, 30-day payment terms = £1M AR (cash tied up). Speed collection to 15 days = £500K AR (half the cash needed). Cost: Discount for early payment (2% discount vs 30 days typical). ROI: High (improve cash without raising capital).
- Collections: Faster AR = faster cash. Tactics: (1) Invoice immediately (not delayed), (2) Offer payment discount (2/10 net 30 = 2% discount if paid in 10 days), (3) Follow-up on overdue (call on day 31, not after 90 days), (4) Auto-renewal (recurring charges automatic, not one-time). Impact: Reduce DSO (days sales outstanding) from 45 to 30 days = 33% cash improvement.
- Payments: Slower AP = keep more cash. Tactics: (1) Pay on due date (not early, keep cash), (2) Negotiate terms (30 day standard, negotiate 45-60 for key suppliers), (3) Bundle payments (monthly vs weekly, fewer transactions). But: Balance with relationships (don't abuse vendors, they're partners). Opportunity: Use supply chain financing (pay early for discount, but finance it).
Managing Working Capital and Optimizing Cash Flow
Improving cash position through efficient working capital management. **Working capital fundamentals** Definition: - Current assets - current liabilities - Focus: Cash tied up in operations Formula: - Working capital = AR (Accounts Receivable) + Inventory - AP (Accounts Payable) - Higher = more cash tied up (bad) - Lower = less cash tied up (good) Example calculation: Current assets: - Cash: £100K - AR: £200K (customers owe us) - Inventory: £50K - Total: £350K Current liabilities: - AP: £100K (we owe vendors) - Payroll payable: £30K - Total: £130K Working capital: £350K - £130K = £220K (cash tied up) **Accounts receivable (AR) management** Definition: - Money customers owe us - Goal: Get paid faster (improve cash flow) Key metric: - DSO (Days Sales Outstanding): Average days to collect payment - Formula: AR / (Revenue / 365) - Example: £200K AR, £1M annual revenue = (£200K / £2,740/day) = 73 days Benchmark: - 30 days: Great (paid within a month) - 45 days: Okay (month and a half) - 60+ days: Poor (taking too long) Collection tactics: Tactic 1: Invoice immediately - Current: Invoice at month-end (delays) - Better: Invoice at service delivery (same day) - Impact: 5-10 day improvement in DSO Tactic 2: Clear terms - Invoice must include: Due date, payment method, early payment discount - Example: Net 30 (due in 30 days), 2/10 (2% discount if paid by day 10) Tactic 3: Early payment discount - Offer: 2% discount if paid within 10 days (vs 30-day terms) - Cost: 2% of revenue - Benefit: 20-day faster collection (reduces AR by 20-30%) - ROI: 2% cost, 30% cash improvement = usually worth it Example: - Current AR: £200K (73-day DSO) - With 2/10 net 30: 40% of customers pay early (faster), 60% pay at 30 days - New DSO: (40% × 10 days) + (60% × 30 days) = 4 + 18 = 22 days - New AR: (£1M annual / 365) × 22 = £60K AR (huge improvement!) - Cost: 40% × 2% = 0.8% of revenue (£8K annually) - Benefit: £140K less AR (£200K → £60K), meaning £140K more cash available - ROI: £140K cash improvement for £8K cost (17.5x return) Tactic 4: Follow-up system - Process: Overdue invoice 5 days, call customer (payment reminder) - Overdue 15 days, escalate (ask why?) - Overdue 30 days, decision (pause service? escalate?) - Impact: Catch issues early, reduce bad debt Tactic 5: Recurring/automatic billing - For subscriptions: Auto-charge credit card (vs invoice + manual payment) - Benefit: Guaranteed payment (customer authorized upfront) - Impact: Near 100% collection rate (only failed card declines) **Accounts payable (AP) management** Definition: - Money we owe vendors - Goal: Pay slower (keep cash as long as possible) Key metric: - DPO (Days Payable Outstanding): Average days before payment - Formula: AP / (COGS / 365) - Example: £100K AP, £300K annual COGS = (£100K / £822/day) = 122 days Strategy: - Increase DPO (pay slower = keep cash longer) - But: Balance with relationships (don't damage vendor relationships) Tactics: Tactic 1: Negotiate terms - Standard: Net 30 (pay in 30 days) - Negotiate: Net 45-60 (pay in 45-60 days) - Benefit: 15-30 extra days of float (keep cash) - Cost: May be no discount, but vendor willing if large customer Example: - 10 vendors, average £10K per month per vendor - Current terms: Net 30 (average DPO 45 days, floating £15K) - Negotiate: Net 60 (DPO 60 days, floating £20K) - Benefit: £5K extra cash float (£20K - £15K) Tactic 2: Bundle payments - Current: Pay vendors weekly (many transactions, costs) - Better: Pay vendors monthly (fewer transactions, less processing) - Benefit: Timing (can batch, last minute payment) - Impact: Negotiate better terms (monthly vs weekly = can offer steady payments) Tactic 3: Volume discounts or early pay incentives - Offer: "Pay £3K this month, save 2% on next £10K purchase" - Trade-off: Discount cost vs cash needs - Use: When cash is abundant, want to reduce AP Tactic 4: Supply chain financing - Mechanism: "Pay vendor day 60 via financing company, they get paid day 10" - Benefit: Vendor gets cash fast (happy), you pay after 60 days (cash preserved) - Cost: Small fee (1-3% of transaction) - When to use: Need vendors happy, have short-term cash flow dip **Working capital optimization** Example: Improving working capital by £200K Current state: - AR: £200K (73-day DSO) - Inventory: £50K - AP: £100K (45-day DPO) - Net working capital: £200K + £50K - £100K = £150K Targets: - AR: £60K (implement early payment discount, 22-day DSO) - Inventory: £50K (no change, not main focus) - AP: £200K (negotiate 60-day terms, double DPO) - Net working capital: £60K + £50K - £200K = -£90K (negative!) Impact: - Improvement: £150K → -£90K = £240K cash improvement - Benefit: £240K more cash available (without raising capital) - Achieved: Better AR collection, better vendor payment terms **Cash conversion cycle** Metric: Days of cash in operations Formula: - CCC = DSO + DIO - DPO - DSO: Days sales outstanding (how long to collect from customers) - DIO: Days inventory outstanding (how long inventory sits) - DPO: Days payable outstanding (how long to pay vendors) Example: Current: - DSO: 73 days (collect from customers) - DIO: 30 days (inventory) - DPO: 45 days (pay vendors) - CCC: 73 + 30 - 45 = 58 days This means you need 58 days of operating cash (to fund gap between paying vendors and collecting from customers) Optimized: - DSO: 22 days (faster collection) - DIO: 30 days (same) - DPO: 60 days (slower payment) - CCC: 22 + 30 - 60 = -8 days (negative!) Negative CCC means vendors finance you (they pay before customers) **Working capital monitoring** Monthly metrics: | Item | Current | Target | Status | |---|---|---|---| | AR (£) | £200K | £60K | £140K excess | | DSO (days) | 73 | 22 | 51 days over | | AP (£) | £100K | £200K | £100K under-utilized | | DPO (days) | 45 | 60 | 15 days short | | Working capital | £150K | -£90K | £240K excess | Actions: - Implement early payment discount (reduce AR) - Negotiate vendor terms (increase AP) - Follow-up on overdue AR (accelerate collection) **Common working capital mistakes** Mistake 1: Ignoring AR - Problem: Customers take 90 days to pay, cash problems - Fix: Enforce terms (follow-up, discount for early payment) - Impact: £100K+ cash improvement possible Mistake 2: Paying early (cash conservation forgotten) - Problem: "We have cash, pay vendor early" - Fix: Pay on due date, not early (keep cash) - Impact: £50K+ monthly cash preservation Mistake 3: No inventory management - Problem: Overstocked inventory ties up cash - Fix: JIT (just-in-time) inventory, turn faster - Impact: 10-20% inventory reduction possible Mistake 4: Not measuring DSO/DPO - Problem: Don't know how long to collect/pay - Fix: Track monthly (DSO trend, DPO trend) - Impact: Focus attention on biggest opportunities
