A Profitable Job Can Still Leave You Short of Cash

Ask two different questions

Imagine a small design business near Gretna Junction finishing a $900 project. The owner wants to know whether the job was worthwhile and whether there is enough money for next week's bills.

Those questions use related information, but they are different. One examines the result of the work.

The other examines money that is available when a payment must be made.

Accounting methods also affect when income and expenses appear in records. IRS Publication 538 explains that cash and accrual methods generally recognize transactions at different times.

Tax accounting has additional rules; the exercise below is a management example, not instructions to adopt or change a tax method. IRS Publication 538

Follow a hypothetical month

Suppose the project has $250 in direct costs and this simplified month has $100 in other operating expenses. Assume all $900 of project revenue is earned this month, with all $350 of related expenses counted this month.

On that stated basis, the example operating profit is $550. For teaching clarity, there are no other sales, expenses, equipment purchases, taxes, or owner withdrawals.

Now follow the bank balance. The month begins with $200.

The customer pays $300 now and owes the remaining $600 later. The business pays the $250 and $100 expenses now.

Ending cash is $200 plus $300 minus $350, or $150. A $550 operating result and $150 of available cash can coexist because part of the earned revenue has not arrived.

If an additional $200 bill must be paid before the customer's balance arrives, the business faces a $50 timing gap. Calling the project profitable does not settle that bill.

Equally, the timing gap alone does not prove that the project's price was wrong. It shows exactly which date and payment assumption need attention.

Build a view that follows dates

On a sheet, give each upcoming week four lines: opening cash, expected receipts, planned payments, and closing cash. Carry each closing amount into the next week.

Put the customer's $600 in the week you reasonably expect it to clear, rather than the week you wish it would arrive. Label that receipt uncertain until payment is confirmed.

Make a second version in which the $600 arrives one week later. The difference between the two versions helps identify the earliest problem.

You might then investigate a corrected invoice, an agreed staged payment for future work, or moving an optional purchase. These are questions to evaluate against real commitments, not automatic instructions to borrow or delay a required payment.

Do not confuse funding with performance

If the owner puts another $500 into the bank account in this example, cash rises from $150 to $650. The project has not suddenly earned another $500 from customers.

Label the transfer so the business's operating performance remains visible. Likewise, receiving a loan would create cash and a repayment obligation; it would not turn the borrowed amount into sales.

The SBA recommends keeping track of receivables, payables, available cash, and bank reconciliation. A short weekly review can bring those views together.

SBA management guide

At your review, ask what changed since the last forecast. Did a customer pay, did a charge settle, or did an expected sale remain only a conversation?

Update the dates and amounts. A forecast is useful because you revise it when evidence changes, not because its first version predicts everything.

Move one receipt

Copy the example into a four-week cash sheet, starting with $200.

Enter the $300 receipt and $350 payments, then schedule the $600 balance.

Move the $600 one week later and highlight any week whose closing cash falls below zero.

Which payment date would you verify first, and what evidence would count as confirmation?
