Transparent by design
Calculations are deterministic, use the values entered in the project, and expose missing or estimated information instead of hiding uncertainty.
Landed inventory total combines supplier merchandise, per-unit packaging and prep, plus known order-level costs such as tooling, inspection, domestic transport, freight, insurance, duty, brokerage, and destination delivery. Missing costs remain missing in confidence and completeness; they are never silently inferred.
merchandise + (per-unit sourcing extras × quantity) + order-level costsThe total sale-ready inventory cost is divided by planned quantity. A zero or invalid quantity produces a structured unavailable result rather than Infinity or NaN.
landed inventory total ÷ planned quantityPer-unit selling costs include referral fee, FBA fulfillment, monthly storage, inbound placement, other marketplace cost, expected advertising cost, and the return-loss reserve.
referral fee + FBA + storage + inbound + other marketplace + ads + returns reserveExpected net profit per unit subtracts landed cost and selling costs from selling price. Net margin divides that result by selling price.
(selling price − landed cost − selling costs) ÷ selling priceBreak-even ACoS is the advertising share available after every non-ad cost. Break-even selling price accounts for percentage-based referral, advertising, and returns assumptions. Non-positive denominators produce an explicit invalid state.
break-even ACoS = (selling price − non-ad costs) ÷ selling priceDeposit due applies the supplier's deposit percentage to merchandise, packaging, and tooling, then adds sample cost. Inventory cash required equals the estimated landed inventory total and excludes ongoing operating overhead.
deposit = manufacturing subtotal × deposit rate + sample costThe launch estimate adds inventory cash to expected advertising spend for the smaller of planned quantity or first-month sales. Amazon disbursement delays are not modeled.
inventory cash + first-month units × advertising cost per unitCoverage divides planned units by expected monthly sales. Payback units estimate how many sales recover inventory cash using cash returned after selling costs; payback months divide those units by expected sales. These are estimates, not demand forecasts.
payback units = ceil(inventory cash ÷ cash returned per sold unit)A weighted 100-point review checks price and quantity, incoterm and origin, deposit and lead time, packing, freight, duty, delivery, prep, and explicit confirmation of other charges. Confirmed zero remains different from missing.
Weighted field-group confirmations, scored from 0 to 100Confidence combines completeness, critical logistics gaps, invalid economics, custom incoterm clarity, and the share of landed cost marked estimated. Every confidence label includes reasons.
High, Medium, or Low from documented deterministic thresholdsEligible quotes receive separate testing, margin, landed-cost, cash, payback, and quote-strength conclusions. The balanced recommendation considers only commercially viable options and internally weights margin, cash, payback, coverage, lead time, and completeness. The internal rank is not presented as a universal public score.
Separate category rules + min-max normalized balanced dimensionsSupplier scenarios inherit the base quote and apply only explicit supported overrides. Freight, advertising, sales, return, and combined downside presets are temporary and reversible; they never overwrite canonical project values.
Base quote + explicit overrides + temporary downside assumptionsTargets use current economics to calculate a maximum unit-price guardrail, a two-month test quantity where relevant, a 30% deposit request for higher terms, lead-time guidance, and missing information required before deposit. SupplyVerdict never suggests negotiating upward.
Targets are generated only where the existing negotiation engine supports themLimitations
