The cash gap: when your bills beat your money to the bank
The cash gap is the period when bills are due but payment has not arrived — the reason profitable months still end in overdraft. Measuring it per week and closing it is the core skill of cash flow management.
- The hidden week
Bills due before income lands — invisible in monthly averages.
- Measured per week
The gap is a dated event: the negative stretch between income dates.
- Five fixes
Shift dates, trim costs, deposits, faster collection, a buffer.
- Profitable ≠ immune
A profitable business with a structural cash gap still runs dry.
Measuring your gap
| Week | Bills due | Income arrives | Gap |
|---|---|---|---|
| 1 | $1,800 | $0 | −$1,800 |
| 2 | $900 | $3,200 | Closed |
| 3 | $1,400 | $0 | −$1,400 |
| 4 | $1,000 | $2,800 | Closed |
The five fixes, in order
- Move bill due dates to follow income dates.
- Trim one recurring cost to widen the cushion.
- Require deposits from clients to pull cash earlier.
- Shorten payment terms and chase receivables.
- Build a buffer equal to the worst weekly gap.
The structural gap
If the gap appears every single week regardless of dates, it is structural — you are spending more per cycle than the income covers. No amount of date-shifting fixes a structural gap; that needs cost cuts or income growth.
The calendar distinguishes the two instantly: a timing gap moves when dates move; a structural gap follows you everywhere.
Frequently asked questions
What is a cash gap?
The period when bills fall due before the income that should cover them arrives — the negative stretch between income dates.
How do I fix a cash gap?
Move due dates, trim costs, take deposits, collect faster, or build a buffer equal to the worst weekly gap.
Is a cash gap the same as negative cash flow?
No — a cash gap is a timing problem; negative cash flow is a structural one. The fixes are completely different.
How do I know if my gap is timing or structural?
Move the dates: if the gap follows the dates, it is timing; if it appears every week regardless, it is structural.
