Is It Bad to Run a Business Off the Bank Balance?
Yes, and here is why. The bank balance tells you what is there today, not how much of it is already spoken for. Payroll, loans, and the yearly bills you forgot all have a claim on it. A 20-minute check every Monday shows what is truly free.

The Short Answer
Why Is Spending Based on My Bank Balance a Problem?
Because part of that balance already belongs to bills you have not paid yet. Subtract the next 30 days of bills, a monthly set-aside for yearly bills, and a cushion. What is left is what you can spend.
You check the balance before you buy. A yearly bill catches you off guard every year. Business and personal money come out of the same account. You have said "but there was plenty last week" more than once.
If a bill you cannot pay is due this month, stop here. That is a Red Flag. Collect what customers owe you, call the creditor about a payment plan, then come back to build the habit.

Not Sure What You Can Really Spend?
Why It Happens
Why Do I Have Money in the Bank but Still Run Short?
- 1
The balance looks like an answer
It is only half of one. The other half is what you owe.
- 2
Yearly bills are invisible
Insurance, permits, taxes, and big repairs hide until the week they arrive.
- 3
Business and personal money are mixed
When it all comes out of one account, nobody can tell what belongs to the business.
The cushion is thinner than most owners think. The JPMorgan Chase Institute found the typical small business held only enough cash to cover 27 days of normal outflows. If you are profitable and still short, read profitable but no cash.

The Fix
How Much Money Can I Actually Spend From My Business Account?
- 1
Pull twelve months of statements
Circle every bill, especially the ones that come once a quarter or once a year.
- 2
Separate the accounts
If business and personal money share an account, open a business account now.
- 3
Build the 90-Day Bill List
Every bill due in the next 90 days, with the amount and the date. That is your 90-Day Bill List.
- 4
Run the Weekly Money Check
Every Monday: balance, minus the next 30 days of bills, minus this month's set-aside, minus your cushion. See the Weekly Money Check.
- 5
Set a purchase limit
Anything over a set dollar amount waits until you have checked the list.
Worked Example
What Does a Weekly Money Check Look Like?
Take a small landscaping company on the first Monday in March. There is $24,500 in the bank, and the owner is about to buy a $6,000 used mower. Here is the check:
| Line | Amount |
|---|---|
| Bank balance | $24,500 |
| Minus bills due in the next 30 days (two payrolls, loans, four weeks of fuel, insurance) | $17,450 |
| Left after the next 30 days of bills | $7,050 |
| Minus this month's set-aside for yearly and quarterly bills | $1,783 |
| Minus the minimum cushion | $3,000 |
| Free to spend | $2,267 |
The math: $24,500 minus $17,450 is $7,050. Minus $1,783 is $5,267. Minus $3,000 is $2,267. Only $2,267 of that $24,500 is really free. The mower waits until that number covers it, or until the owner plans for it on purpose.
When Dr. Paul steps into a business as a fractional CFO, the first question is not what is in the bank. It is what is owed in the next 90 days. The bank balance is a snapshot. The bill list is the forecast. A yearly insurance payment is not a surprise. It is a calendar problem. Owners who solve it with fast, expensive money end up paying for the same forgotten bill twice.
For Managers
How Do I Track Spending Against a Budget at Work?
Bills and purchase requests often cross your desk first. Keep the 90-Day Bill List current and flag any bill that shows up without being on it. Agree with the owner on your limit: purchases under a set amount you approve after checking the list. Anything over it, and any loan or credit offer, goes to the owner.

For Business Students
What Is the Difference Between Cash Basis Spending and Budget Based Spending?
Cash basis spending decides by what is in the account today. Budget based spending decides by what the plan says is available after known obligations. The Weekly Money Check is a simple short term cash forecast: obligations on one side, today's cash on the other. For a longer view, see the 13-week cash flow forecast.
