Separate records, quotes and assumptions before pricing
Prerequisites, sequence and stop points
- Name the product, saleable unit, currency, period and indirect-tax basis. (not complete)
- Record each cost component as a record, quote or assumption with owner and date. (not complete)
- Give low, base and high endpoints a specific rationale rather than adding a default buffer. (not complete)
- Test one candidate price across every case and keep margin distinct from markup. (not complete)
- Keep fixed-cost and volume exposure separate; use break-even only when the period basis is declared. (not complete)
- Pause when a load-bearing cost is unbounded or may be double counted. (not complete)
Build a bounded cost range on one basis
gross margin = (candidate price − unit cost) ÷ candidate price
- candidate price
- Same test price in every cost case (CU per saleable unit) — user-entered scenario
- unit cost
- Low, base or high cost with a named rationale (CU per saleable unit) — record, quote or labelled assumption
The result is a bounded scenario, not evidence that customers will accept the price.
| Cost component or case | Low | Base | High | Rationale or review trigger |
|---|---|---|---|---|
| Low endpoint evidence | 38 CU | Not used | Not used | Fictional current written supplier quote plus completed pilot fulfilment record; review when either record expires or the unit specification changes |
| Base endpoint evidence | Not used | 44 CU | Not used | Fictional alternative supplier quote plus observed small-batch packing record; review after the next production batch or quote revision |
| High endpoint evidence | Not used | Not used | 53 CU | Fictional small-order supplier quote plus high-case carrier and fulfilment quote; review when order quantity or shipping method is fixed |
| Candidate price | 80 CU | 80 CU | 80 CU | Same tax-exclusive price in every case |
| Gross margin | 52.50% | 45.00% | 33.75% | Provisional scenario result, not viability proof |
| Fulfilment estimate | Included once | Included once | May duplicate landed-cost quote | STOP and reconcile possible double counting |
| Known-record components | Included: completed pilot fulfilment record; excluded: unverified future changes | Known records stay separate from the alternative supplier quote and packing estimate | Known records stay separate from the high-case supplier, carrier and fulfilment quotes | Keep included and excluded components on the same saleable-unit, currency and indirect-tax basis |
| Current-quote components | Included: current written supplier quote; excluded: expired or superseded quotes | Included: alternative supplier quote; excluded: an estimate presented as a quote | Included: current supplier, carrier and fulfilment quotes; excluded: any duplicated quoted line | Retain quote owner and date; do not convert a quote into a known cost |
| Estimate components | Included only when separately named; excluded when already captured by a record or quote | Included: observed small-batch packing estimate as a labelled estimate | Excluded: any fulfilment estimate already included in the landed or fulfilment quote | STOP on an unbounded load-bearing estimate or unresolved double count |
Choose a provisional action and evidence trigger
Labelled scenario
All values are invented neutral-currency inputs. The scenario tests arithmetic only and does not predict demand.
| Case or record | Inputs and arithmetic | Interpretation |
|---|---|---|
| Low/base/high comparison | (80 − 38) ÷ 80 = 52.50%; (80 − 44) ÷ 80 = 45%; (80 − 53) ÷ 80 = 33.75% | Choose only a provisional action that survives the declared downside |
| Double-count boundary | A 12 CU fulfilment estimate may already be in the supplier landed-cost quote | STOP until cost ownership is reconciled |

Questions and limitations
- Which case should be treated as expected?
- None by default. Each endpoint needs evidence and a rationale; the base label does not create probability.
- Should fixed costs be added to unit cost?
- Only with a declared allocation and volume basis. Otherwise keep them in a same-period break-even scenario.
