# Contribution Variable Selling Cost Scope

Include supplied variable selling costs before calling product contribution equal to gross profit.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
Unit price,variable manufacturing and selling costs,quantity and classification policy.

## Workflow
1. Record costs that vary with output or sales.
2. Subtract both supplied manufacturing and variable selling costs.
3. Keep fixed costs outside unit contribution but visible for later break-even.
4. Return illustrative contribution,not accounting profit or cash.

## Output contract
price | variable_make | variable_sell | contribution_unit | units | contribution_total | hold

## Fictional acceptance test
Fictional price 100, variable manufacturing cost 30 and variable selling cost 10 give 60 contribution per unit. At 50 units, total contribution is 3000. Excluding selling cost would overstate unit contribution by 10.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
