Set one comparable decision contract
Record these assumptions before calculating
- Event price, scope and payment schedule. (not complete)
- Supplier order, cancellation and refund dates. (not complete)
- Preparation and labour commitments by checkpoint. (not complete)
- Invoice date, due date and expected bank date. (not complete)
- Locally reviewed cancellation, postponement, change and refund terms. (not complete)
pre-event cash exposure = supplier commitments + scheduled labour and preparation + other unavoidable cash outflows - customer cash cleared
- supplier commitments
- Non-cancellable or cancellation-adjusted supplier amounts at the checkpoint (CU by date) — purchase order and supplier terms
- scheduled labour and preparation
- Documented work or committed paid capacity before the event (CU by date) — run sheet, roster and time record
- customer cash cleared
- Funds received in the bank, not merely invoiced (CU by date) — bank and receivables record
Keep one currency, indirect-tax basis, time horizon and cost boundary throughout. Scenario values below are invented currency units (CU), not benchmarks.
Worked example: Deposit and Cancellation Terms for Events
Invented event: 10,000 CU price, 3,000 CU customer cash received; at a checkpoint the business has 2,200 CU non-cancellable supplies, 1,100 CU documented preparation and 500 CU other unavoidable outflows.
| Line | Calculation | Result |
|---|---|---|
| Unavoidable commitments | 2,200 + 1,100 + 500 | 3,800 CU |
| Customer cash cleared | entered receipt | (3,000 CU) |
| Pre-event exposure | 3,800 - 3,000 | 800 CU |
| Deposit coverage | 3,000 ÷ 3,800 | 78.9% of stated commitments |
| Case | Changed input | Decision result |
|---|---|---|
| Earlier cancellation | Commitments 1,900; cash 3,000 | (1,100 CU exposure) |
| Base checkpoint | Commitments 3,800; cash 3,000 | 800 CU exposure |
| Later checkpoint | Commitments 6,200; cash 3,000 | 3,200 CU exposure |
Turn the calculation into an operating decision
- Map service and supplier commitments by observable date.
- Separate invoice, due and cleared-cash dates.
- Calculate cash exposure at each checkpoint.
- Draft deposit, progress and cancellation mechanics around those checkpoints.
- Obtain local contract, tax and consumer-law review.
- Reconcile cancellations and postponements to actual commitments and the agreed terms.
- Calling an invoice cash.
- Treating every deposit as earned profit.
- Choosing a percentage without mapping commitments.
- Using vague cancellation dates or unverifiable work stages.
- Presenting internal exposure as the customer refund calculation.
Questions to settle before acting
- How large should a deposit be?
- Model the pre-event exposure and commercial friction, then obtain local advice; there is no universal percentage.
- Should cancellation terms use days or milestones?
- Use observable checkpoints that match real commitments. A hybrid can be clearer when supplier and preparation events occur on different dates.
- Is retained cash profit?
- No. Cash held, accounting revenue, tax treatment, unavoidable cost and profit are different records.
