The Cash Conversion Review: Can Your Growth Pay for Itself?

A business can be busy, profitable on paper, and still short of cash.

The usual version looks familiar. Sales are rising. A large customer wants more product. The team needs another hire, more inventory, or additional production capacity to keep up. The owner sees an opportunity and asks the natural question: should we finance the expansion?

That may be the right question eventually. It is not the first one.

First, determine whether each new dollar of revenue releases cash or absorbs more of it. Growth that consumes cash faster than the business can generate it is not automatically bad. Many healthy companies invest ahead of demand. But it has to be deliberate, measured, and funded with a clear understanding of the gap.

We call this the cash conversion review. It is an operating review, not a lender exercise. Its job is to show where money gets tied up between the moment you commit to serving a customer and the moment that customer pays you.

Start with the cash path, not the income statement

Your income statement answers whether the business created profit over a period. Your cash path answers whether you can survive the timing required to create that profit.

For a product business, the path may look like this:

1. Pay a supplier deposit.
2. Receive and hold inventory.
3. Sell and ship the product.
4. Invoice the customer.
5. Wait for payment.

For a service business, substitute payroll and work in progress for inventory. You may pay a team for six weeks before a project milestone is billable, then wait another 30 days for the client to pay.

In both cases, a signed order is not cash. Revenue booked is not cash. Even gross margin is not cash until the collection cycle is complete.

A useful starting measure is cash conversion days:

days inventory or work in progress + days sales outstanding - days payables outstanding

You do not need perfect accounting to use it. Estimate the average number of days cash is tied up in each stage. Then compare that number with six months ago. If revenue is growing and the cash conversion period is widening, your operating model is demanding more capital per dollar of sales.

Run four checks before you call growth self-funding

1. Test the incremental order, not the company average

Company-wide margins can hide a bad growth channel. Take a representative new order and map the actual cash required to fulfill it.

Include supplier deposits, direct labor, freight, commissions, returns allowance, payment processing, and any customer-specific setup work. Then note when each cash outflow happens and when the customer is likely to pay.

Suppose a distributor receives a $100,000 order with a 35% gross margin. On the surface, that is attractive. But it requires a $45,000 supplier payment before shipment, $12,000 in freight and handling, and payment terms of net 60 after delivery. The order may produce profit, but it can still create a meaningful cash hole for several months.

That is not an argument against taking the order. It is an argument for pricing, terms, and financing it correctly.

2. Identify the commitment that cannot move

Not every cost has the same flexibility. Supplier deposits may be nonrefundable. Payroll lands on a fixed schedule. Rent, insurance, software contracts, and existing debt payments keep arriving whether collections are early or late.

Separate your outflows into three buckets:

• Costs paid only after an order is won.
• Costs committed before demand is certain.
• Fixed commitments that continue regardless of sales volume.

The second bucket deserves the most attention. This is where founders often confuse capacity with demand. Adding inventory, a salaried salesperson, or a second location can improve capacity. It also raises the cash cost of being wrong.

Before adding a fixed commitment, define the trigger that earns it. For example: hire after a specific backlog level has held for two billing cycles, or place the larger inventory order only after deposits cover a defined share of the purchase. The trigger should be observable, not based on a general feeling that momentum is building.

3. Find the fastest operational release of cash

When cash is tight, founders often jump to cutting expenses. Some cuts are necessary, but the highest-leverage fix is frequently inside the cycle itself.

Ask four practical questions. Can customers pay a deposit or move from net 60 to net 30? Can invoices go out at shipment or milestone completion rather than at month-end? Can purchasing be split into smaller, more frequent orders? Can a supplier extend terms after a consistent payment history?

Each change has a tradeoff. Asking for deposits can create sales friction. Reducing inventory can increase stockout risk. Pressing suppliers too hard can weaken a relationship that matters. The goal is not to maximize one metric. The goal is to reduce cash tied up without damaging the customer experience or the supply chain.

A good operating target is specific: reduce average collection time by ten days, convert half of custom orders to a deposit model, or eliminate work completed but not invoiced within five business days. Assign an owner and review the result weekly.

4. Match capital to the proven gap

After the operating levers are clear, financing becomes easier to evaluate. Capital should bridge a measured timing gap, not cover an undefined feeling that growth needs cash.

Short-cycle inventory and receivables needs may fit a revolving facility, trade terms, or carefully managed card usage. Equipment that produces value for years generally needs longer-duration financing. A permanent increase in payroll or overhead deserves more caution because it is not naturally repaid when one customer pays an invoice.

Also test the downside. If a customer pays 30 days late, a purchase order is delayed, or gross margin comes in below plan, can the business still make its required payments? Your answer should build from the minimum debt payment, not a best-case sales forecast. The framework in finding your debt service floor before borrowing is useful here because it separates a manageable payment from one that depends on everything going right.

Put the review into a weekly operating rhythm

The cash conversion review only works if it changes decisions. Update it each week with a short list: cash on hand, invoices due in the next 14 days, purchase commitments, payroll, debt payments, and the largest sales opportunities that require upfront spend.

Then look forward at least 13 weeks. That window is long enough to expose the timing collision between a supplier payment, payroll, and slow collections, while still being close enough to manage actively. If your forecast is built mostly from assumptions, start with the 13-week cash test before you borrow and make the assumptions visible.

The discipline matters more than precision. A weekly forecast will be wrong in places. But a business that sees its likely cash gap six weeks early has options: collect faster, delay a purchase, negotiate terms, slow hiring, or arrange capital before urgency drives the decision.

A Practical Next Step

Choose one recent customer order and map every dollar out and every dollar in, by date. Do not use averages at first. Use the actual deposit, labor, shipment, invoice, and collection timing. That one exercise usually reveals whether the immediate problem is margin, payment terms, inventory, fixed commitments, or a financing gap.

If the gap is real and repeatable, a funding readiness check can help organize the cash evidence and operating assumptions before you start comparing offers. The objective is simple: make sure growth leaves the business stronger after the cash cycle closes, not more dependent on the next sale.
