2.3 · The Weekly Cash and Inventory Loop

A business can record sales, produce positive modeled contribution, wait on part of a payout, and still have less cash available than its account balance suggests. These are not contradictions. The measures answer different questions. Sales describe transactions. Contribution tests the economics of what sold. Cleared cash shows what has reached the account. Deployable business cash asks how much of that balance remains after commitments and the reserve you have chosen to protect.

​

Follow one sale through the week

Here is one hypothetical chronology. Every amount is invented. The $500 sales figure uses the same revenue perimeter as Chapter 2.2: item price plus any shipping or handling amount retained by the business. This example has no retained shipping or handling, so the full $500 is item price. Its only nonzero Chapter 2.2 selling and fulfillment costs are the $50 venue/payment cost and $25 postage/supplies shown below. Loss allowance, labor, and allocated fixed cost are set to zero only to keep the cash chronology readable; they are not general assumptions. The sale’s modeled contribution is: $500 − $300 − $50 − $25 = $125 Ending cleared cash is: $1,000 + $350 − $25 − $400 − $50 = $875 Deployable business cash is: $875 − $125 of commitments − $200 protected reserve = $550 The expected payout was $450 after the $50 venue/payment cost. With $350 cleared, $100 remains pending. The $300 inventory cost reduces the sale’s contribution, but that cash left the account in an earlier week. Subtracting it again from this week’s cash would count the same outflow twice. The $400 purchase has the opposite timing: it reduces cash now, but it is not the cost of the item that sold in this example. That timing difference is why an active week can produce positive contribution while cash falls, or weak contribution while cash rises because an older payout finally cleared.

​

Keep the measures separate

Use the same definitions each week:

• Sales are the period sum of Chapter 2.2 modeled order revenue: item prices plus any shipping or handling amount the worksheet defines as retained by the business, before costs.
• Modeled contribution is Sales minus the recorded inventory cost of items sold and the modeled selling and fulfillment costs from Chapter 2.2. It remains distinct from net profit.
• Net profit asks what the whole business earned after all applicable expenses for the period. This weekly operating view does not calculate every expense or formal adjustment, so it does not report net profit.
• Ending cleared cash is the reconciled business-account balance at the review time.
• Pending payouts belong to completed sales but have not yet reached the business account. They are tracked, not spent.
• Deployable business cash is a course management measure: ending cleared cash minus named near-term commitments and the reserve protected by your capital policy.
• Owner draws are recorded separately because they reduce what the business can use, even though they are not part of a customer’s order.

These definitions support operating decisions; they do not replace formal bookkeeping or choose an accounting or tax method. Apply one consistent inventory-cost convention in your records, and use qualified advice for the formal treatment that fits the business.

Measure inventory movement

Cash returns from inventory only when stock sells and the proceeds clear. Two simple measures show how quickly that is happening without declaring one speed correct for every product. First, record item age: Item age = review date − acquisition date Age tells you which stock deserves attention. It does not tell you what price to choose; Chapter 2.4 owns that decision. Second, calculate turns over one stated period using the same cost basis: Average inventory at cost = (opening inventory at cost + closing inventory at cost) ÷ 2 Inventory turns = inventory cost of items sold during the period ÷ average inventory at cost for the same period Calculate turns only when average inventory at cost is greater than zero. If it is zero, record turns as not computable for that period. For a hypothetical 90-day period: Inventory cost of items sold = $3,000 Opening inventory at cost = $3,200 Closing inventory at cost = $2,800 Average inventory at cost = ($3,200 + $2,800) ÷ 2 = $3,000 Turns = $3,000 ÷ $3,000 = 1.0 This example demonstrates the formula only. It does not define a healthy turn rate. Do not use market value in one part of the ratio and inventory cost in the other, and do not combine a short-period numerator with a long-period average.

​

Build the weekly view

Use the same internal cutoff for when a completed sale enters the dashboard, the same review time, and the same inventory-cost basis from week to week. This keeps the comparison consistent. Before the first review, choose both inputs used by the inventory rows: Turns period: ___ Inventory review-date rule: ___ Recorded operating decision, owner, and next review date: ___ Finish the review with one operating decision. You might delay a purchase because the payout is still pending, inspect an aging group before the next pricing review, or investigate why contribution fell while sales rose. The dashboard does not decide for you. It shows which question the next decision must answer.
