What Matters

A profitable agent service can run short of cash while waiting for its first invoice to clear. Supplier prepayment, unbilled work, payment terms, growth, settlement and late collection each move the funding requirement. DN’s model follows those dates and reports the largest cash deficit. Its examples are hypothetical; the decision should use actual supplier terms and customer collection evidence.

The agent has finished the job. Revenue has been recorded. The supplier still needs money today, while the customer pays next month. That sequence is a cash problem even when the sale earns a margin. A purchasing and billing workflow should expose it before accepting the next workload.

An agent business can earn a margin on every completed job and still need cash before its customers pay. Two separate intervals create this problem: paying a supplier before consuming its service, and consuming that service before issuing the customer invoice. A monthly profit calculation can conceal both.

Daily cash outflows are an approximation, unsuitable for measuring lumpy prepaid purchases without replacing the event schedule. No creditworthiness, solvency, demand or collections forecast is provided.

1. Supplier prepayment moves cash out before consumption

Anthropic’s API billing guidance distinguishes prepaid credit use from monthly billing arranged through its sales process. That is a provider-specific example, not a rule for every account. The relevant evidence is the actual billing arrangement available to the business, including any order form and credit limit.

Record the cash purchase of credits when it occurs. If a business buys 30,000 of credits on the first day and consumes them throughout the month, the cash event is a 30,000 outflow on day one. Spreading it into 1,000 daily outflows may describe consumption but understates the opening cash requirement. Counting the original purchase and those daily consumption entries as separate cash costs would make the opposite error.

2. Completed work waits for the customer invoice

The second interval begins when the business consumes a supplier service and ends when the resulting customer work can be invoiced. Even without supplier prepayment, daily costs can accumulate before a monthly invoice is issued. Record the work date, its customer and the agreed billing trigger; do not treat a completed job as a cash receipt.

A practical review follows one job through completion, acceptance and billing. If the customer must approve a deliverable before an invoice qualifies, retain the acceptance evidence and unresolved exceptions. An internal report can show earned revenue while the cash calendar still contains no collectible invoice. The remedy depends on which event is missing.

The DN calculator uses daily cash outflows for clarity. A prepaid deployment should replace that approximation with its actual top-up dates. Keep a cost ledger for margin and a cash ledger for funding, linked through the same customer and job identifiers. This article concerns a permitted value-added service using authorised supplier access. It does not assume a business may resell accounts, API keys or entitlements that its supplier contract prohibits.

3. Payment terms start after the billing period

The third gap appears when payment terms start after the work has accumulated. “Monthly billing” states how often an invoice is produced. It does not say when cash arrives. Thirty days of work followed by thirty days to pay can require funding for substantially longer than one month.

In a hypothetical example, a business spends 1,000 per day and bills 45,000 for each 30-day period. Its supplier cash cost per period is 30,000, so the planned difference is 15,000 before fixed costs, tax and other omissions. If the first invoice is issued at the end of day 30 and collected at the end of day 60, the business needs 60,000 to cover outflows before that first receipt. The illustration processes daily costs before same-day receipts.

The result is not a forecast that every monthly service needs two months of funding. A deposit, earlier collection, existing receivables or a different event order changes it. A supplier demanding the whole period’s cost in advance can also increase the initial peak. The value of the example is that it exposes which date creates the gap.

Read the trigger behind the terms. Payment may run from a valid invoice, acceptance, a customer’s approved purchase-order process or another specified event. “Net-30” entered by an agent is incomplete if the parties disagree about when day one begins. Capture the contractual trigger, the expected date and the evidence that the trigger actually occurred.

4. Growth finances the next cohort before the first pays

The fourth gap comes from expanding work during the collection delay. Revenue growth and cash collection need not move together. The business may have to finance a larger second cohort while the first cohort’s invoice remains outstanding.

Keep the first month’s hypothetical daily cash cost at 1,000, then double it to 2,000 in the second month. Before the first receipt at the end of day 60, cash outflows total 90,000. That is 30,000 more than the flat-volume example. The additional requirement follows from the timing of the larger workload, even if the markup is unchanged.

This is different from a supplier price increase. Growth changes the amount of work; repricing changes the cost of that work. Separate those assumptions so that a cash problem has an identifiable cause. The tool scales both period costs and customer billings by the same growth factor, holding the markup constant. It does not claim that demand, productivity or collection quality will actually behave that way.

A real growth review should include onboarding, dedicated capacity, support and customer-specific commitments. Those may arise before the first usage event and may not disappear if the customer cancels. Candidate changes include an agreed deposit, shorter billing interval or revised payment terms. Each changes the commercial offer and should be evaluated with the customer relationship and contract, rather than being silently imposed by the agent.

5. A customer payment still waits to become usable cash

The fifth gap is between a customer paying and the business obtaining usable funds. Stripe’s balance documentation distinguishes pending and available balances and describes settlement timing. A payment event in an application is therefore not, by itself, evidence that the corresponding amount can fund today’s supplier bill. Actual availability depends on the relevant account and payment arrangements.

Keep the customer payment timestamp and the expected usable-funds timestamp as separate fields. The supplier payment may require funds in a different account from the one displaying the pending balance. Confirm the relevant payout or transfer step and compare its expected completion with the supplier deadline. Record unresolved timing instead of assuming immediate availability.

6. Late collection extends the funded interval

The sixth gap is collection later than planned. Separate lateness from an ordinary settlement delay. A customer dispute, invalid invoice, missed approval or changed payment date needs a different response from a processor balance still becoming available. Combining all delays into one average makes ownership unclear.

With constant daily cash costs of 1,000, ten additional days before the first receipt add 10,000 to the initial funding need in the basic example. That relationship is conditional: costs must continue, no other receipts must offset them, and the first collection must remain the limiting event. The interactive model follows the event sequence rather than assuming the same shortcut applies to every growth scenario.

Methodology, limitations and corrections

Methodology. Every worked figure is hypothetical. Period k has daily cash cost c ×(1+g)^k and customer billing equal to that cost ×period length ×billing multiplier. A period invoice arrives after the period ends plus the entered payment, lateness and settlement delays. The model subtracts each day’s cost before crediting that day’s receipts, then reports the largest cumulative deficit. With daily cost 1,000,30-day periods, a 1.5 billing multiplier and 30-day terms, required opening cash is 60,000 in the flat-volume example. Cash beyond the selected horizon, existing receivables and omitted obligations can materially change a real result.

Use a cash calendar as the acceptance rule

A cash calendar turns the six gaps into a reviewable purchasing decision. Each expected receipt or payment needs an amount, account, date, evidence status and owner. A forecast receipt remains a forecast until the expected event happens. The ledger should preserve both the original expectation and the actual outcome so recurring errors become visible.

The DN Cash-Gap Model calculates the largest cumulative deficit within a defined horizon. Opening cash is then compared with that requirement. The first shortfall day is useful because an eventual positive balance cannot repair a payment already missed. The ending balance is also reported, but should never replace the peak-deficit test.

Run flat-volume, growth and delayed-collection cases separately. A negative-growth case can be informative when the business retains supplier commitments after demand falls. This simple model does not include that asymmetry automatically; add those commitments to a full calendar before using the result to approve a customer.

A sensible operating decision names the maximum additional funding the business will commit, the evidence that permits more work, and the response when an invoice misses its date. These are commercial controls. A high gross margin or an agent’s confident completion message cannot substitute for available cash.

Check the actual scope of funding controls

Account controls need equally precise meanings. OpenAI’s prepaid billing guidance distinguishes automatic recharge limits from total usage and notes that cutoff can lag consumption. A recharge setting should not be treated as a complete contractual or technical cap on the cash exposure of every customer job. Match limits to the supplier’s documented behaviour and retain an exception path when the assumed bound fails.

For corrections, identify the claim, source and date when contacting Decentralised News. A new record-creation timestamp does not refresh its underlying evidence.

Frequently asked questions

Is profit enough to fund growth?

Not necessarily. Profit measures the relationship between revenue and costs; the cash calendar records when payments and usable receipts occur.

Why does the model pay costs before same-day receipts?

It is an explicit conservative event-order assumption. Replace it with actual intraday order if reliable evidence supports another sequence.

Can a prepaid credit purchase be treated as daily spending?

Only as an approximation. For a funding decision, record the actual cash purchase date and avoid counting later consumption as another cash outflow.

Does the tool decide whether a customer is creditworthy?

No. It shows the funding effect of entered assumptions. Creditworthiness, contractual rights and collections reliability require separate evidence.
