What Matters
Losing a large customer removes collections faster than it may remove supplier commitments and service costs. Model the cash timeline, including exit work and a minimum operating balance, before calling the business resilient. DN’s scenario shows when the entered cash floor is breached. It does not predict a customer exit, available financing or the survival of a real business.
Revenue concentration is visible in a customer chart. Cash vulnerability sits in the dates: when the last payment arrives, which obligations remain due and how quickly the business can change its spending. A profitable historical customer can leave behind an expensive commitment.
DN’s customer-loss model focuses on that transition. It differs from a generic cost-per-task calculation because some costs continue after the work disappears. The objective is a reviewable decision about the next commitment and a dated response plan, using explicit assumptions rather than a single runway ratio.

DN Customer-Loss Cash-Runway Model
Project monthly cash after one customer leaves. Base spending excludes the separately entered temporary stranded cost. Exit cash is paid in month one.
Enter your assumptions or load a labelled example. Required blank numbers stay missing; unknown evidence remains unknown. Use nonpersonal labels only. This instrument makes no network requests and uses no persistent browser storage.
Use your own inputs
No current result. Complete inputs or load an illustrative example.
Constant monthly amounts, one currency and no financing assumed. No legal solvency, tax or investment advice. Irregular receipts, multiple cost-release dates and intra-month obligations require a detailed calendar.
1. Establish usable cash for the obligations
The first check is cash available for these obligations. Start with an unrestricted balance that can actually be used in the modeled account and currency. Exclude money held for another purpose, unavailable credits and hoped-for financing unless a separate scenario explicitly includes them.
The Australian Government cash-flow guide treats opening balance, cash incoming, cash outgoing and closing balance as distinct elements and asks for estimates to be labelled. DN applies that structure to one customer-loss scenario. The tool’s monthly cadence is a simplification; a business with tight payroll or prepayment dates may need a daily or weekly calendar.
2. Map the collections that remain
Map the departing customer’s final invoices, payment dates and unresolved disputes. Do not assume an invoice will be collected because the revenue was recognized. For remaining customers, use expected cash receipts with their timing and evidence. A cancelled contract may stop future billing immediately while leaving a delayed final collection, or it may leave no further receipt at all.
Outstanding receivables deserve their own evidence status. A final invoice accepted by the customer, a disputed invoice and an unbilled estimate should not all enter the same collection date with equal confidence. The narrow tool uses a constant remaining-collections input; a full calendar should place each material receipt separately and preserve the reason for its expected date. Run a delayed or missing-receipt scenario when the amount could change the action deadline.
3. Separate the continuing business’s operating costs
The third check is ongoing costs of the remaining business. Identify the spending needed to keep serving the customers who remain. Separate these continuing costs from extra commitments attributable to the departing customer, so the same expense is not counted twice. A usage-based cost may decline, but only by the amount the remaining workload no longer requires.
4. Identify stranded commitments and release dates
The fourth check is costs that survive temporarily after the customer exits. A usage-based input may fall with activity, but a reserved capacity contract, dedicated service or notice-period payment may continue. Verify the actual obligation and release date rather than classifying everything labelled variable as immediately avoidable.
Keep changes within the business’s authorized and contractual options. A model that assumes a supplier can be stopped next week should have evidence for that date. Record any termination charge, minimum commitment or retained service needed to support other customers. The calculator does not decide whether a contract may be cancelled.
Avoid counting the same stranded cost in both the base operating spend and the temporary extra field. Write the cost boundary beside the scenario. If the obligation declines in several steps, use a more detailed schedule. The narrow tool supports a constant temporary amount for a specified number of months, which should not be mistaken for every real exit pattern.
5. Include the one-off exit work and payment
The fifth check is the one-off transition payment. Data export, handover, final support, refund obligations or replacement of customer-specific infrastructure may require cash after the main relationship ends. Include the relevant obligation only once and record when it is due. The local model places the entered exit payment in month one; other timing needs a fuller schedule.
6. Choose and explain the operating cash floor
The sixth check is the minimum operating cash floor. This is a business-selected scenario boundary, not a universal recommended reserve. It can represent the amount the operator does not want to fall below while meeting near-term obligations. Record why it was chosen and which payments it must support.
A zero ending balance is not the only meaningful warning. The business may need to act well before it reaches zero to avoid committing to work it cannot fund. Conversely, falling below a chosen planning floor does not by itself determine insolvency or inability to pay a particular debt. Keep those legal and financial judgments separate from the arithmetic.
7. Choose responses by their dated cash effect
The seventh check is an actionable response. Compare permitted actions by when their cash effect arrives, not by the size of a headline saving. A new sale with a long collection delay may not fund the immediate transition. A negotiated supplier release may help sooner, but only if the supplier has agreed and any charge is included.
Keep a base scenario and a named stress, such as one remaining customer paying a month late. Do not average the two into a falsely precise forecast. The date of a breach and the amount needed at that time may matter more than the average monthly burn. Assign an owner to update actual receipts and payments as the scenario develops.
Before taking another concentrated contract, examine whether the new customer requires dedicated commitments that outlast its own cancellation terms. Price and negotiate those obligations with the evidence available. Growth can increase the mismatch if every new customer brings a longer supplier commitment. This article does not claim that growth is inherently dangerous; it shows the specific timing question to resolve.
The maintained record should identify each assumption, its source, the next date it can change and the decision it affects. Review it when a major customer renews, changes scope, pays late or gives notice. A customer-concentration percentage is a useful prompt; a cash calendar shows which obligation must be handled next.
Avoid treating a future sale as an immediate replacement for the lost customer. The new customer may require onboarding expenditure before its first payment and may buy a different volume or service mix. Model those cash events separately. A response that improves annual revenue can still worsen the next month’s funding gap. The relevant question is when usable cash arrives relative to the obligations already due, not whether the sales pipeline eventually looks large enough.
Methodology, limitations and corrections
Reconcile opening usable cash to an actual record and map collections and payments to their expected dates. Distinguish signed commitments, confirmed receipts and estimates. Use the actual contractual release dates for costs and preserve uncertainty when they are unresolved.
The worked amounts are synthetic. The formula adds receipts and subtracts payments each month, carrying the closing balance forward. Compare actual results with the scenario and revise the forecast without overwriting historical assumptions. A decision about borrowing, taxes or legal obligations requires the relevant professional and contractual assessment, which this tool does not provide.
Worked example: the customer-loss cash timeline
In a synthetic scenario, opening usable cash is 30,000 CU. Remaining customers provide 12,000 CU per month, and base cash spending is 16,000 CU. A stranded supplier commitment costs another 4,000 CU per month for three months. There is a 6,000 CU exit payment in month one, and the selected minimum cash floor is 5,000 CU.
Month one closes at 16,000 CU: 30,000 + 12,000 − 16,000 − 4,000 − 6,000. Month two closes at 8,000 CU. Month three closes at zero, so the first modeled breach of the 5,000 CU floor occurs in month three. Once the stranded cost ends, the business still spends 4,000 CU more each month than it collects.
A negative projected balance in later months represents an unfunded gap in the scenario. It does not assume that a bank will allow an overdraft or that the business can continue paying without a response. The tool reports the gap rather than inventing new funding. Any financing scenario needs its own confirmed availability, cost and timing.
Now suppose the stranded commitment lasts one month instead of three, with all other inputs unchanged. Month two closes at 12,000 CU, month three at 8,000 and month four at 4,000. The floor breach moves to month four. Faster cost release buys time but does not repair the continuing monthly deficit. That distinction helps separate an exit problem from the remaining business’s economics.

Frequently asked questions
Why not divide cash by monthly burn?
That shortcut can miss one-off exit payments and costs that stop at different times. The timeline shows the effect of those transitions.
Does a negative projection assume an overdraft?
No. It identifies an unfunded gap. Financing must be separately evidenced and modeled.
Is the cash floor a legal threshold?
No. It is a user-selected planning boundary. The tool does not assess solvency or legal payment obligations.
Can the business be profitable but have a cash problem?
The timing of collections and payments can differ from accounting revenue and expense. This model explicitly tracks the entered cash flows.
