The business is busy. Why is cash still tight?

A business can sell more, report a profit, and still struggle to pay the next bill. That is not a contradiction. Sales, profit, and available cash answer different questions.

The practical answer is usually timing. Money may be recorded as revenue before it reaches the bank. Inventory, payroll, rent, debt, tax, and owner withdrawals may require cash before the related sales are collected. A growing business can make that gap larger.

Three numbers that are easy to mix up

Revenue is the amount earned from selling goods or services before most costs are subtracted.

Profit is what remains after the costs assigned to that period are subtracted under the business's accounting method.

Cash is the money the business can use now. It changes when money actually enters or leaves the business's accounts.

Suppose a design firm finishes a $30,000 project in September and gives the customer 30 days to pay. The firm may record September revenue, but the cash may not arrive until October. September payroll and rent still have to be paid in September.

The opposite can happen too. A customer may pay a deposit before all of the work is completed. Cash arrives first, while some revenue may be recognized later. The exact accounting treatment depends on the facts and the method used.

Where the cash goes

Customers have not paid yet

Invoices are not bank deposits. A sale on 30-day terms creates a waiting period. Late payments stretch it. If sales grow while collection slows, receivables can rise faster than cash.

Check the expected payment date of every material invoice. Do not place an invoice in this week's forecast only because it is due. Place it where the customer is realistically expected to pay, then note the risk.

Inventory is paid for before it is sold

A retailer, restaurant, or manufacturer may pay for goods days or months before collecting from customers. Buying too much ties cash up in stock. Buying too little can lose sales. The decision is not simply to cut inventory. It is to know which purchases are required, when they will turn into sales, and when those sales will become cash.

The IRS distinguishes gross receipts, purchases, expenses, and inventory in business records. Those distinctions matter for tax and accounting, but a short cash forecast uses the dates money is expected to move. Keep the forecast connected to the underlying invoices, bills, payroll records, and bank activity.

Profit does not include every cash movement in the same way

Loan principal payments use cash but are not normally an expense on the income statement. Buying equipment may use cash immediately while the cost is recognized over time. Owner draws or distributions reduce business cash but are not ordinary operating expenses. Sales tax collected for a government may be sitting in the bank even though it is not available for the owner to spend.

This is why a profitable month can still produce a lower bank balance.

Taxes arrive in blocks

Income tax, payroll tax, sales tax, and other obligations do not always leave the account at the same pace as sales. A business that does not reserve for them can mistake tax money for operating cash. Put known payment dates into the forecast. If the amount is uncertain, use a documented estimate and mark it for review with the appropriate professional.

Growth has to be financed

More work often requires labor, materials, deposits, marketing, or equipment before the customer pays. A large order can make the cash position worse before it makes it better. Growth is not the problem by itself. The problem is accepting a timing gap the business cannot fund.

Before accepting a large order, model the deposits, purchasing dates, payroll, completion date, customer terms, and collection risk. Then decide whether the price, deposit, delivery schedule, credit line, or order size must change.

A 13-week example

Consider a fictional service business with $42,000 in the bank. It expects weekly customer collections, but a large customer will not pay until week five. Payroll is due every other week. Rent, debt, estimated tax, and a yearly insurance payment fall inside the same period.

The business looks healthy across the full quarter. Total expected receipts exceed total expected payments. Yet the weekly view reveals a shortfall in week four, before the large customer payment arrives.

That finding changes the decision. The owner can now work on a specific gap instead of reacting to a vague feeling that cash is tight. Possible actions include collecting a deposit, confirming the late invoice, moving a nonessential purchase, arranging a credit facility before it is needed, or reducing an owner withdrawal. None of those actions is automatically correct. The forecast shows when a decision is required and how large the gap may be.

Build the forecast from dates, not averages

A monthly average can hide a Friday payroll or a tax payment that arrives before the month's largest deposit. A useful 13-week forecast has one column per week and begins with cash that is actually available.

For each week:

1. Enter the opening cash balance.
2. Add customer receipts and other cash that is reasonably expected to clear that week.
3. Enter payroll, rent, purchasing, debt, tax, and other required payments on their expected payment dates.
4. Calculate net cash movement and ending cash.
5. Carry that ending balance into the next week.
6. Compare ending cash with the minimum balance the business intends to protect.

The lowest projected balance matters more than the quarter-end balance. A business can end week thirteen with plenty of cash and still fail to meet a payment in week four.

Use confidence, not wishful precision

Do not pretend every forecast number is equally certain. Confirmed deposits and signed customer schedules are stronger than hoped-for sales. A tax estimate may require professional review. A disputed invoice should not be treated like cash in the bank.

For each significant receipt, ask:

• Is the amount supported by an invoice, order, contract, or recurring history?
• Has the customer confirmed the payment date?
• Could a refund, dispute, or processing delay change the result?

For each significant payment, ask:

• Is the due date fixed?
• Can timing change without damaging the business or breaking an agreement?
• Is the payment missing because no one entered it?

Update it every week

The forecast is useful because it changes. At the weekly review:

• replace last week's estimate with what actually happened;
• move unpaid customer receipts to realistic dates;
• add newly known bills and obligations;
• revise uncertain amounts when better evidence arrives;
• record the reason for any large difference;
• decide who will act on the lowest projected balance.

Do not quietly change an overdue receipt to make the forecast look better. Moving it later is more honest and more useful.

What the sheet cannot decide

A 13-week forecast does not determine whether the business is profitable, whether a loan is affordable over its full term, whether an expense is deductible, or how a transaction should be recorded in the financial statements. It is a short planning view of expected cash movement.

It also depends on the information entered. Missing payroll, tax, debt, inventory, or owner payments will make the result misleading. Compare the sheet with the bank, accounts receivable, accounts payable, payroll schedule, tax calendar, loan schedule, and planned purchases.

The next useful action

Open the Black Lentil 13-week cash workbook. Complete the example first, then replace the example with the business's opening cash, expected receipts, and dated payments. Review the lowest projected balance with the person responsible for collections and payments.

If the forecast shows a shortfall, write down the amount, the week, the assumptions causing it, the owner of the next action, and the date the result will be checked.
