Cash Flow: The Number One Killer of Small Businesses

An events company in Kigali had a great 2024. Revenue was up 40%. They were profitable on paper. But in March 2025 they almost couldn’t make payroll. How? They’d delivered three large events in February and March. Clients had 30-day payment terms. Suppliers needed paying immediately. The gap between money going out and money coming in nearly killed a profitable business.

Cash flow vs profit — they’re not the same thing

Profit is what your books say you made over a period. Cash flow is whether you have actual money in the bank right now. You can be profitable for the year but have zero cash in February because all your receivables are outstanding.

82% of small businesses that fail cite cash flow as the primary cause. Not bad products. Not weak demand. Cash timing.

Warning signs

• You’re consistently paying suppliers late
• You’re dipping into personal savings to cover business expenses
• You can’t take on a new project because you can’t afford the upfront costs
• You’re choosing which bills to pay this week and which to defer
• Your MoMo business balance swings wildly between empty and flush

Practical fixes

Shorten your receivables

• Invoice on the same day you deliver, not next week
• Offer a 5% discount for payment within 7 days — it’s worth it to get cash in faster
• Require 50% upfront for new clients or large projects
• Follow up on overdue invoices immediately, not after 30 days

Lengthen your payables (carefully)

• Negotiate 30-day terms with reliable suppliers
• Don’t pay early unless there’s a discount for doing so
• Stagger large purchases across months

Build a buffer

Every business should have 2–3 months of operating expenses saved. This sounds impossible when you’re starting, but even saving RWF 100,000/month builds up. This buffer is the difference between surviving a slow month and closing.

Track it

You can’t fix what you can’t see. At minimum, maintain a simple spreadsheet: money in this week, money out this week, balance. Better yet, use a business dashboard that tracks cash flow automatically and alerts you when the balance drops below your safety threshold.

Cash flow management isn’t glamorous. But it’s the difference between a business that survives and one that doesn’t.
