A rental calendar shows booked work, not when cash will reach the bank. A deposit collected last month may already be paying this week's bills, while the remaining event balance arrives after an equipment payment is due. An inflatable rental cash flow forecast makes that timing visible without counting the same customer payment twice.

This guide builds one six-week example, recalculates two timing changes and shows how to carry an actual payment variance forward. The figures are fictional USD cash amounts, not industry benchmarks or a profit forecast. Tax, refund, financing and other cash movements must be added where applicable to a real business.

The cover scene is illustrative and AI-generated; it does not show actual customer financial records.

Separate the Opening Cash From Uncollected Orders

Start at a defined cutoff with an opening cash figure reconciled to the account being forecast. Identify restricted amounts or funds unavailable for ordinary payments separately. Use a consistent account scope; moving money between two accounts inside that scope is not new customer income.

In this example, opening cash is 6,000. Existing orders total 12,000, of which 6,000 in deposits was collected before the cutoff and is already reflected in that opening balance. Only the remaining 6,000 is forecast as a future receipt, in Week 5. Adding all 12,000 to future income would count those deposits again.

A new booking contributes a further 2,000 deposit in Week 1. Only that deposit falls within this example's receipt schedule; any other balance for that booking lies outside the six-week window. A real forecast should extend far enough to include the corresponding future delivery costs and obligations.

Put Each Receipt and Payment in Its Expected Week

Use expected bank receipt or payment timing rather than the event date alone. Keep the contractual due date and current collection expectation in separate fields when they differ. Mark assumptions clearly and use actual terms or customer confirmation to support the forecast.

The Australian government's cash flow statement guide provides the underlying opening-balance, incoming and outgoing structure. Here it is applied weekly: closing cash = opening cash + receipts − payments. The closing figure then becomes the following week's opening figure.

Separate staff and operating payments, committed supplier payments and proposed purchases in the supporting schedule. For a potential addition from the commercial bouncer range, use the actual quoted payment schedule rather than placing the full purchase against an assumed delivery week. Apply the same discipline to a proposed inflatable combo purchase.

Work Through the Base Forecast

The first modeled shortage appears in Week 3, and the lowest weekly closing figure is −2,000 in Week 4. Returning to zero by Week 6 does not remove that earlier gap. The negative entries show an unresolved funding need if the schedule proceeds unchanged; they are not an available overdraft or proof that the bank would process those payments.

Across the window, opening cash of 6,000 plus receipts of 8,000 equals payments of 14,000. That total reconciles to the zero ending figure, but totals alone hide the shortage. Weekly closing balances can also hide a gap within a week, so move to daily timing around tight payment dates.

Change One Timing Assumption at a Time

For the first comparison, suppose the Week 3 payment of 5,000 represents a new equipment purchase that has not been ordered or committed. If the business chooses not to make that purchase during the window, the closing balances become 8,000, 4,000, 4,000, 3,000, 6,000 and 5,000. The lowest closing figure is now 3,000.

That scenario removes an optional cash outflow from this window. It does not authorize postponing an existing payable, ignoring wages or changing a signed supplier agreement. If terms are already committed, any revised timing needs the appropriate agreement before it becomes a confirmed forecast assumption.

For the second comparison, restore the base payments and move the existing 6,000 event balance from Week 5 to Week 6. The closings become 8,000, 4,000, −1,000, −2,000, −5,000 and 0. Total receipts are unchanged, but the lowest closing figure deteriorates to −5,000. Moving a receipt changes every subsequent balance until it arrives.

The deposit and payment policy article deals with setting terms. This forecast uses the actual agreed terms and collection expectations; it does not create new penalties or assume that a deposit is unrestricted profit.

Replace Predictions With Actual Cash Movements

Keep a dated copy of the forecast before updating it. Reconcile actual receipts and payments for the completed period, explain the differences and revise future expected dates. Remove a predicted receipt once its actual movement has replaced it so both versions are not counted.

For a simple variance example, Week 2 payments actually total 4,500 instead of the predicted 4,000. With everything else unchanged, Week 2 closes at 3,500. Weeks 3 through 6 then close at −1,500, −2,500, 500 and −500. Recording the extra 500 only in Week 2 while leaving later balances unchanged would break the forecast.

Roll the planning window forward after reconciliation, add the next week's expected movements and preserve an explanation for each significant change. Separate a customer promise from a receipt already settled in the bank. If processor fees are deducted from payouts, choose a consistent gross-and-fee or net-payout treatment that reconciles without counting the fee twice.

Use the Forecast to Identify the Decision Date

GoodEvent's event-business cash flow page identifies deposits, balances and overdue collections as practical planning needs. Its promotional results are not assumptions in this example. Your decision should follow your own recorded receipt dates, payment obligations and available funds.

Review the first shortage, the lowest balance and how much notice remains before each critical payment. Investigate uncertain receipts and optional spending while there is time to act. Recompute the schedule after any agreed change; a discussion alone does not change the bank balance.
