Why I Keep a Cash Reserve Instead of Buying Everything
Every dollar in inventory becomes temporarily unavailable.
Returns, repairs, unexpected opportunities, and normal expenses all need cash. If you invest every dollar, one surprise can force a bad sale. A reserve gives you room to operate calmly.
What it is
Keeping a portion of business cash unavailable for normal inventory purchases.
Why it matters
Returns, repairs, tax, shipping surprises, and strong opportunities can appear unexpectedly.
When to use it
Use once you have multiple active inventory units or higher-value transactions.
How to do it
Set a minimum cash floor based on average item value, refund exposure, operating costs, and volatility. Treat the reserve as untouchable for ordinary purchases.
Worked example
With $10,000 cash, you may reserve $2,000 and treat $8,000 as buying power. A supplier lot that requires all $10,000 is not affordable under your rule, even if it looks profitable.
Your action plan
- Choose reserve floor
- Separate reserve from buying power
- Review monthly
Common mistakes
- Using reserve for 'one great deal'
- Setting reserve too low for item values
- Counting expected sales as available cash
