Commercial analysis
Commercial evaluation with the uncertainty left in.
Brisora commercial analysis does three things: it calculates landed cost and gross margin from explicit inputs, compares bill-of-materials options on cost, compatibility and supplier risk, and evaluates a proposed commercial action against a mandate.
Each is deterministic arithmetic or fixed rules. An unknown input stays unknown and blocks the result rather than being estimated. Commercial evaluation is not execution authority: nothing here places, pays for or approves anything.
Every component carries how well it is known.
Landed cost is unit price times quantity, plus the cost components you supply. Amounts are whole minor units, such as cents, so totals are exact.
- Components: freight, insurance, customs duty, tax, handling, FX adjustment, payment cost, capital cost, risk reserve and discount
- A component is a flat amount or a rate applied to merchandise value
- Each amount can carry a low and a high bound, giving expected, best-case and worst-case totals
- Each component states its basis: contracted, quoted, from a table, estimated or unknown
| Option | Status | Worst-case margin | Open item |
|---|---|---|---|
| Supplier A | VERIFIED | Above floor | None |
| Supplier B | ESTIMATED | Near floor | Freight is an estimate |
| Supplier C | UNKNOWN | No result | Missing FX rate |
Verified, estimated, unknown
The status of a total is the status of its weakest input.
Every input has a firm basis
All components that feed the total are contracted, quoted or taken from a table.
At least one input is an estimate
The total is usable, and it is never reported as verified.
The calculation could not be completed
No total is returned at all, and the reasons are listed. An unknown cost is never counted as zero.
FX inputs and gross margin
Exchange rates are evidence you supply. Margin is judged on the worst case.
FX inputs
- You provide each exchange rate with its source and date
- Brisora never fetches or infers a rate
- A component in another currency with no rate makes the result UNKNOWN
- A conversion is rounded once, to the nearest minor unit
Gross margin and worst-case economics
- Given a buyer price, margin is computed for the expected, best and worst case
- A margin floor is checked against the worst case only
- If landed cost is unknown, no margin is produced
BOM comparison
Options are excluded for stated reasons, not ranked optimistically.
A bill of materials is a set of component choices. Brisora computes the landed cost of each component itself, then evaluates each option against a hard cost ceiling and a softer review threshold.
Not valid
Landed cost is unresolved, a mandatory compatibility check failed or is unknown, or worst-case cost exceeds the hard ceiling.
Valid, needs human review
Worst-case cost is above the review threshold, the cost data includes estimates, or a component comes from a higher-risk supplier.
Recommended
The cheapest valid option, unless it relies on a higher-risk supplier and saves less than 5% against a safer one. Then the safer option is preferred, and the result says so.
- Compatibility. You supply the checks already evaluated, each marked mandatory or preference. An unmet preference is reported but does not invalidate an option.
- Supplier-risk flags. You mark which components come from a higher-risk supplier. Brisora compares options using that flag; it does not score suppliers itself.
ALLOW, DENY or ESCALATE, against an explicit mandate.
A commercial mandate is a versioned statement of what may be done: which kinds of action, within which limits. Brisora evaluates one proposed action against one mandate and returns the outcome with every rule it checked.
- Authority is an allow-list: an action class the mandate does not name is denied
- Transaction value against the mandate's financial limit
- Worst-case gross margin against the mandate's floor
- Geography and counterparty: allowed, blocked, or requiring review
- Supplier risk ceiling, required evidence and hard stop conditions
- ESCALATE names what a person must approve; the engine cannot approve it
Evaluation is not authority
An ALLOW is an analysis result.
ALLOW means the proposed action is consistent with the mandate you supplied. It does not authorize the action and it does not perform it. Through Brisora MCP nothing is executed at all: no order, no payment, no signature.
The mandate is read and never changed. Brisora does not issue mandates and cannot widen one.
The rule trace returned with each evaluation is described under how Brisora preserves decision provenance. Where this logic sits relative to the AI client is on the architecture page. All three analyses are exposed as tools by Brisora MCP.
