Cash Flow Management: Survival Guide for SMEs
Learn to forecast, monitor, and improve your cash flow. Discover strategies to avoid the cash crunch that kills 80% of small businesses.
Introduction
Cash flow is the lifeblood of any business. It's not about how much profit you make on paper—it's about having enough cash available to pay your bills, employees, and suppliers when those payments are due. Many profitable businesses fail because they run out of cash. This guide will help you understand, monitor, and optimise your cash flow.
Understanding Cash Flow
Cash flow refers to the movement of money into and out of your business. Positive cash flow means more money coming in than going out. Negative cash flow means you're spending more than you're receiving—and you'll need reserves or credit to cover the gap.
Cash Flow vs Profit
Many business owners confuse profit with cash flow. Here's the difference:
- Profit: Revenue minus expenses (accounting concept)
- Cash Flow: Actual cash received minus cash paid out
- You can be profitable but cash-poor (unpaid invoices)
- You can be cash-rich but unprofitable (selling assets)
The Three Cash Flow Categories
- Operating Activities: Day-to-day business (sales, payments, wages)
- Investing Activities: Equipment, vehicles, property purchases/sales
- Financing Activities: Loans received, loan repayments, owner drawings
Cash Flow Forecasting
A cash flow forecast predicts when money will come in and go out, helping you plan ahead and avoid surprises. Every business should maintain a rolling cash flow forecast.
Creating Your Cash Flow Forecast
Build Your 13-Week Cash Flow Forecast
Sales receipts (based on realistic collection timing), deposits, loans, grants, refunds, other income.
Rent, salaries, supplier payments, loan repayments, taxes, insurance, utilities, other expenses.
Don't put invoice date—put when you'll actually receive/pay cash. Be realistic about payment delays.
Opening balance + inflows - outflows = closing balance. This closing becomes next week's opening.
Every week, compare actual to forecast. Adjust future weeks based on what you've learned.
Cash Flow Forecast Template
Your weekly cash flow forecast should include:
- Opening cash balance (start of week)
- Expected customer receipts (by customer if possible)
- Other income (deposits, refunds, etc.)
- Total inflows
- Supplier payments (list major ones individually)
- Salaries and wages
- Rent and utilities
- Tax payments
- Loan repayments
- Other expenses
- Total outflows
- Net cash flow (inflows minus outflows)
- Closing cash balance (opening + net)
Speeding Up Cash Inflows
The faster you collect money owed to you, the healthier your cash flow. Here are proven strategies to accelerate customer payments.
Invoice Best Practices
- Invoice immediately upon delivery/completion
- Make invoices clear with all required details
- Include payment terms prominently
- Provide multiple payment options (EFT, card, cash)
- Include your banking details clearly
- Follow up the day payment is due
Payment Terms Strategies
- Shorten payment terms (30 days → 14 days)
- Offer early payment discounts (2% for payment within 7 days)
- Request deposits upfront (30-50% for large projects)
- Use milestone payments for long projects
- Consider payment on delivery for new customers
- Build payment terms into contracts from the start
Debtor Management
- Send payment reminders before due date
- Follow up on day 1 of overdue (don't wait!)
- Have a clear escalation process (call → letter → final notice)
- Know your customers' payment processes
- Consider credit insurance for large accounts
- Review credit limits regularly
Additional Income Strategies
- Offer prepaid packages at a discount
- Create subscription/retainer arrangements
- Accept card payments (faster settlement than EFT)
- Invoice for disbursements separately and immediately
- Consider invoice factoring for large invoices
Managing Cash Outflows
While you want to collect money quickly, you also want to manage when you pay out. This doesn't mean paying late—it means paying strategically.
Payment Timing Strategies
- Use all of your payment terms (if terms are 30 days, pay on day 30)
- Batch payments (weekly payment runs instead of daily)
- Schedule major payments after expected receipts
- Negotiate extended terms with suppliers where possible
- Take advantage of early payment discounts when cash-positive
Expense Management
- Review all recurring expenses quarterly
- Cancel unused subscriptions and services
- Negotiate better rates with suppliers
- Consider alternative suppliers for better terms
- Buy in bulk when it makes cash flow sense
- Lease vs buy analysis for major equipment
Supplier Negotiations
Good supplier relationships can improve your cash flow significantly:
- Ask for extended payment terms (30 → 45 or 60 days)
- Request consignment stock arrangements
- Negotiate volume discounts
- Explore early payment discounts they offer
- Build relationship for flexibility during tough times
Fixed vs Variable Costs
Understanding your cost structure helps with cash flow planning:
- Fixed costs: Same regardless of sales (rent, salaries, insurance)
- Variable costs: Change with sales volume (materials, commissions)
- Try to convert fixed costs to variable where possible
- Know your break-even point (minimum sales to cover fixed costs)
The Cash Conversion Cycle
The Cash Conversion Cycle (CCC) measures how long it takes to convert your investments in inventory and other resources into cash from sales. A shorter cycle means better cash flow.
Understanding the Cycle
- Days Inventory Outstanding (DIO): How long stock sits before sale
- Days Sales Outstanding (DSO): How long customers take to pay
- Days Payables Outstanding (DPO): How long you take to pay suppliers
- Cash Conversion Cycle = DIO + DSO - DPO
Improving Your Cycle
- Reduce inventory: Just-in-time ordering, faster turnover
- Collect faster: Better invoicing, follow-up, deposit requirements
- Pay strategically: Use full payment terms, negotiate extensions
- Goal: Get CCC as low as possible, ideally negative
Cash Flow Emergencies
Even well-managed businesses face cash crunches. Having a plan for emergencies can save your business.
Early Warning Signs
- Regularly bouncing payments or exceeding overdraft
- Delaying supplier payments beyond terms
- Can't take early payment discounts anymore
- Using personal funds to cover business expenses
- Growing debtor book with slow collections
- Declining cash reserves
Emergency Actions
- Contact your bank about temporary overdraft increase
- Reach out to key debtors for accelerated payment
- Talk to suppliers about extended terms (before you're late)
- Review expenses for anything that can be cut/delayed
- Consider invoice factoring for immediate cash
- Explore short-term business finance options
- Owner injection if possible and appropriate
Building an Emergency Fund
Every business should build cash reserves for emergencies:
- Target: 3-6 months of operating expenses
- Start with 1 month, build from there
- Keep in separate, easily accessible account
- Don't use for normal operations
- Replenish immediately after any emergency use
