Limit Prepaid Service Sales by the Appointments Still Owed

Count promises alongside receipts

Selling prepaid appointments can make a quiet week look financially transformed. Cash arrives immediately, while the customers' claims on future dates remain. The operating decision is how many packages to sell without creating an appointment backlog that crowds out ordinary bookings or consumes the cash intended for rent. A receipt ledger answers how much money arrived; an obligation ledger answers how many services remain to be delivered. The business needs both before distributing the apparent surplus.

The IFRS Foundation's public IFRS 15 overview links revenue to transferring promised goods or services. This article does not determine formal revenue recognition, breakage or refund accounting. Its management question is narrower: can the business finance and schedule every promised appointment if customers actually redeem? Assuming low use merely because previous customers were slow to book can conceal an exposure concentrated near holidays, expiry reminders or a change in customer availability.

Translate the promotion into hours and cash

Assume an invented service business sells 40 packages at USD 300, each promising four one-hour appointments. It receives USD 12,000 and owes 160 appointment hours. Every delivered appointment requires USD 35 of incremental cash for a paid practitioner and supplies. Existing rent and administrative salaries are unchanged. The ordinary cash price is USD 100 per appointment, so an ordinary sale contributes USD 65 before those unchanged costs. Package receipts average USD 75 per appointment before delivery costs.

Over the next four weeks the business has 120 deliverable hours after breaks and administration. Customers paying ordinary prices would buy 80 of them if those hours remain available. Thus only 40 hours are genuinely spare. The promotion may create 160 total obligations while providing just 40 hours of spare near-term capacity. This is a scheduling concentration problem even if every package ultimately produces positive contribution. Booking policies must communicate realistic access before the promotion is sold.

Stress the redemption wave

Consider redemptions of 40, 80, 120 or 160 hours within the four-week window. With 40 redeemed hours, all ordinary demand fits. With 80 redeemed hours, 40 ordinary hours are displaced. With 120, all 80 ordinary hours are displaced. With 160, existing capacity is insufficient even after displacing every ordinary booking; the model adds 40 external hours costing USD 60 each instead of the normal USD 35. External delivery is assumed contractually permitted and available only in that final scenario.

ACCA explains that forgone benefits can be relevant to a decision. Here the forgone benefit is USD 65 for each ordinary appointment displaced, because the USD 35 delivery payment is avoided when that ordinary booking is lost. The table therefore distinguishes actual delivery cash from opportunity cost. Subtracting the USD 100 ordinary selling price and also charging the avoided USD 35 would exaggerate displacement. Neither the table nor the lost contribution is an accounting statement of reported profit.

Protect the undelivered portion of the receipt

At 40 redemptions, actual delivery payments are USD 1,400 and 120 promised appointments remain. Earmarking USD 35 for each remaining appointment requires USD 4,200. After reserving both paid and future delivery costs, USD 6,400 of the original receipts remains before unchanged overhead and tax. At 80 redemptions, cash delivery is USD 2,800 and future delivery provision is another USD 2,800. The apparent bank balance falls, but the combined base delivery commitment stays USD 5,600.

The table's final column subtracts delivery payments, the provision for undelivered appointments and displaced ordinary contribution from USD 12,000. It falls from USD 6,400 at 40 redemptions to USD 1,200 at 120. At 160 it is USD 200, because external fulfillment adds USD 1,000 over normal delivery cost. The reserve is a management earmark, not proof that those funds are legally segregated or sufficient to satisfy every customer remedy. Refund rights may require a different amount.

A cash earmark does not prove that future appointments fit the calendar. As a separate second-window stress, keep the next four-week capacity at 120 hours and ordinary demand at 80 hours, stop new package sales, and deliver all 120 hours carried from the 40-redemption row. Only 40 hours were spare; 80 ordinary hours are displaced. At USD 65 contribution per ordinary hour, that adds USD 5,200 of opportunity cost, reducing the first window's USD 6,400 residual to USD 1,200 over the combined horizon. The USD 4,200 delivery cash was already earmarked, so it must not be deducted again. If outside capacity instead costs more than USD 35 an hour, even the delivery earmark can be insufficient. Neither reserve is an owner-distribution ceiling until both the remaining cash costs and future booking capacity are validated.

Choose a cap that fits the booking calendar

If the business wants to preserve all 80 ordinary hours and expects every package appointment to be requested during the next four weeks, it can support only ten packages: 40 spare hours divided by four appointments. Selling 40 packages requires either a longer agreed service window, additional deliverable capacity or acceptance of displaced ordinary demand. A cap based on average historical redemptions should be accompanied by a concentration test, because an average does not limit what existing customers can request simultaneously.

The price of external capacity provides another sensitivity. At full redemption the package receipts, less normal delivery for 120 hours and lost ordinary contribution, leave USD 2,600 to cover 40 external hours. The zero-residual external cost is therefore USD 65 per hour. That is only a narrow upper boundary before unchanged overhead, tax and refunds. Paying USD 65 would leave nothing for those items; an acceptable operating quote should leave an explicit cushion rather than aim at that boundary.

Keep scheduling and cash controls connected

Government cash-flow guidance recommends identifying estimated incoming and outgoing cash. Apply that discipline by linking every redeemed appointment to a delivery payment date and every outstanding package to an unperformed-service count. If the practitioner is paid before the customer attends, move the cash date accordingly. A prepaid sale collected through a processor can also be temporarily withheld; the worked example assumes the full USD 12,000 is already available and would overstate liquidity if settlement restrictions applied.

A separate account can make a delivery earmark easier to follow, but cannot create capacity. Equally, a booking cap without a cash reserve can leave scheduled work unfunded. Reconcile packages sold, appointments redeemed, valid cancellations, refunds and appointments still owed at least as often as the promotion changes. Investigate a balance that falls because records were deleted or an expiry date was assumed, rather than because the promise was performed or validly extinguished.

Authorize a promotion with an exit plan

Before launch, count deliverable hours, ordinary demand, existing prepaid obligations and the maximum new redemption wave. Verify whether substitutions, booking windows and outside practitioners are allowed and acceptable to customers. Obtain the actual incremental delivery cost and identify who pays when appointments must be repeated or refunded. Set a package cap from the constrained calendar, then test whether the resulting receipts cover all dated payments without relying on another round of prepaid sales.

After launch, track redemption concentration and stop additional sales when remaining obligations approach the protected capacity limit. Offer customers clear options if access becomes constrained rather than silently lengthening waits. Keep the delivery earmark separate from owner withdrawals until the outstanding obligations have been reconciled. The final choice may be a smaller promotion, scheduled redemption slots or no package sale at all; the useful result is an obligation that the business can perform without sacrificing an unmeasured part of its ordinary trade.

Limits of this analysis

• Redemption priority and simultaneous demand are stress assumptions; actual booking rights and customer preferences may differ.
• The USD 35 earmark funds assumed performance costs, not full contractual refunds or statutory remedies.
• External delivery requires availability, quality control and permission to use substitutes; none is guaranteed.
• Fixed overhead, taxes and payment charges remain to be funded from the planning residual.
• Outstanding appointments are carried forward without expiry or estimated breakage; applicable accounting and unclaimed-property rules are not determined.
• The table excludes future-window displacement and premium capacity costs beyond its base delivery earmark; the separate second-window stress demonstrates why the remaining calendar must be checked.
