Choose a cohort and decision horizon
Define one offer, traffic source, reader situation, country, currency, start date, and comparison period. Decide whether the model informs a small content test, continued maintenance, or expanded promotion. Set an authorized production cost, cash shortfall, and review date before entering optimistic assumptions. Cohorts should not mix old and new program terms or materially different audiences. If the available data cannot be reconciled to a common scope, stop with an unknown rather than averaging incompatible records.

Build a versioned terms sheet
Record program entity, agreement and incorporated-policy URLs, checked dates, eligible products, rate basis, exclusions, session or attribution rule, link requirements, allowed channels, validation period, reversal reasons, threshold, payment method, currency, schedule, tax documentation, termination, and change notice. Save a dated internal snapshot and link the live public document. Amazon’s agreement incorporates multiple policy documents, so reading only the headline commission statement is incomplete. Assign an owner to each term likely to change.
Reconcile the historical transaction funnel
Create monthly columns for qualified clicks, tracked orders, pending amount, approved amount, declined amount by reason, later adjustments, payable balance, and received cash. Preserve order dates and payment dates separately. Awin’s validation process lists cancellations, full returns, failed payments, attribution differences, policy violations, non-fulfillment, and fraud as possible decline reasons. Investigate changes in reason mix rather than using one reversal percentage forever. Mark any dashboard export whose definitions or time zone are uncertain.

State the unit economics without false precision
For each scenario enter conversion rate, eligible order value, commission rule, survival after validation, variable operating cost, and ongoing editorial burden. Calculate expected approved commission, expected received cash, contribution after costs, and break-even qualified clicks. Use ranges when rates are tiered or order value is volatile. Separate data, program terms, and editorial estimates with cell colors or fields. Do not infer conversion from clicks that were not comparable or use gross cart value when the program pays only on eligible subtotal.

Run low, base, and high-reversal cases
Choose reversal rates from scoped evidence, then make uncertainty visible. In a constructed example, Offer A produces $500 gross commission before reversals and costs $260 to maintain. At eight, twenty, and forty percent reversal, approved amounts are $460, $400, and $300; contribution becomes $200, $140, and $40 before financing cost. Add a second sensitivity for conversion or eligible order value rather than changing every variable together. The model is a decision aid, not a claim that these figures describe a real program.

Place approvals and receipts on a cash calendar
Move each cohort through expected validation, threshold crossing, invoice or payment run, bank processing, and possible hold. Show opening cash, authorized spend, expected receipt, adverse receipt, and lowest balance by month. A commission can be economically positive yet arrive after the site must pay writers, hosting, or review costs. Model currency conversion and payment fees only when applicable and supported. If one merchant’s delayed payment would breach the loss ceiling, reduce exposure or require a larger evidence buffer.
Stress the rules and the operation
Test a commission-rate cut, longer validation, attribution loss, threshold miss, payment delay, high returns, merchant closure, and the removal of one allowed channel. Then test editorial burdens: source refresh, reader support, compliance correction, and product replacement. Industry growth does not make an individual program reliable; PMA’s aggregate study is contextual evidence only. Record the first stress that makes the offer unattractive, because that trigger is more actionable than a single expected-value ranking.

Approve a bounded test and reconcile on schedule
A second reviewer should reproduce formulas, trace every term, and confirm that refunds are not counted both in conversion and survival. Approve only the smallest cohort that stays within adverse-case loss and reader-integrity limits. At each review, replace assumptions with comparable observations, explain variance, and preserve the prior forecast. Stop expansion when unexplained declines, unpaid approved balances, term conflicts, or reader harm remain unresolved. The final sheet should show decision, owner, next check, and the evidence needed to reopen it.
