Written and reviewed by Seller Profit Guard Editorial Team.

Use current platform settings and official documentation for offer eligibility, stacking, application order, shipping treatment, commission, and budget behavior. Use authorized seller reports for aggregate retained outcomes, product mix, costs, postage, adverse loss, and capacity. Publish definitions and counts, never raw buyer or order records.

promotion evidence map comparing plan and stress campaign economics, capacity, target headroom, and decision — This original diagram explains an evidence-backed campaign stress test with synthetic aggregates.

Source promotion mechanics

Capture platform settings, eligible products, redemption limits, combination rules, and effective dates. In the promotion evidence map, record the value, unit, source version, evidence date, maturity state, owner, reviewer, and declared uncertainty. Recompute from a clean aggregate or synthetic packet before formatting any revenue, rate, cost, boundary, or decision.

Link current official documentation. Topic 1 includes a supported input, a broken input, a correction path, and the reason the conclusion belongs to an evidence-backed campaign stress test rather than a prediction or universal promotion rule.

Source order outcomes

Use a mature comparable cohort for placed, canceled, refunded, returned, and retained counts. In the promotion evidence map, record the value, unit, source version, evidence date, maturity state, owner, reviewer, and declared uncertainty. Recompute from a clean aggregate or synthetic packet before formatting any revenue, rate, cost, boundary, or decision.

Close the outcome window. Topic 2 includes a supported input, a broken input, a correction path, and the reason the conclusion belongs to an evidence-backed campaign stress test rather than a prediction or universal promotion rule.

Source revenue mix

Weight regular merchandise revenue by expected product and quantity mix. In the promotion evidence map, record the value, unit, source version, evidence date, maturity state, owner, reviewer, and declared uncertainty. Recompute from a clean aggregate or synthetic packet before formatting any revenue, rate, cost, boundary, or decision.

Preserve the source period. Topic 3 includes a supported input, a broken input, a correction path, and the reason the conclusion belongs to an evidence-backed campaign stress test rather than a prediction or universal promotion rule.

Source direct costs

Use current product, packaging, fulfillment, and shipping records. In the promotion evidence map, record the value, unit, source version, evidence date, maturity state, owner, reviewer, and declared uncertainty. Recompute from a clean aggregate or synthetic packet before formatting any revenue, rate, cost, boundary, or decision.

Separate variable from monthly overhead. Topic 4 includes a supported input, a broken input, a correction path, and the reason the conclusion belongs to an evidence-backed campaign stress test rather than a prediction or universal promotion rule.

Source advertising and commission

Use a date-bounded campaign budget and the actual contractual commission base. In the promotion evidence map, record the value, unit, source version, evidence date, maturity state, owner, reviewer, and declared uncertainty. Recompute from a clean aggregate or synthetic packet before formatting any revenue, rate, cost, boundary, or decision.

Do not infer spend from clicks. Topic 5 includes a supported input, a broken input, a correction path, and the reason the conclusion belongs to an evidence-backed campaign stress test rather than a prediction or universal promotion rule.

Source adverse loss

Reconcile non-recovered refund, return, replacement, dispute, and inventory loss once. In the promotion evidence map, record the value, unit, source version, evidence date, maturity state, owner, reviewer, and declared uncertainty. Recompute from a clean aggregate or synthetic packet before formatting any revenue, rate, cost, boundary, or decision.

Document credits and recoveries. Topic 6 includes a supported input, a broken input, a correction path, and the reason the conclusion belongs to an evidence-backed campaign stress test rather than a prediction or universal promotion rule.

Source capacity

Use inventory, labor minutes, packaging throughput, carrier pickup, and service-level evidence. In the promotion evidence map, record the value, unit, source version, evidence date, maturity state, owner, reviewer, and declared uncertainty. Recompute from a clean aggregate or synthetic packet before formatting any revenue, rate, cost, boundary, or decision.

Name the binding constraint. Topic 7 includes a supported input, a broken input, a correction path, and the reason the conclusion belongs to an evidence-backed campaign stress test rather than a prediction or universal promotion rule.

Release and restoration: seasonal promotion margin data sources

Require typecheck, unit, integration, build, content, similarity, SEO, images, browser, mobile, privacy, live, and rollback evidence. Control 1 names the authority, owner, review frequency, exception code, threshold, expiry, correction trigger, and prior restorable campaign packet.

Restore on formula, routing, privacy, accessibility, or health regression. Apply the control specifically to an evidence-backed campaign stress test; distinguish platform settings, seller records, formulas, estimates, and scenario assumptions in the evidence ledger.

Maturity and timing: seasonal promotion margin data sources

Close the campaign reporting, cancellation, refund, return, dispute, and cost-ingestion windows. Control 2 names the authority, owner, review frequency, exception code, threshold, expiry, correction trigger, and prior restorable campaign packet.

Keep provisional outcomes explicit. Apply the control specifically to an evidence-backed campaign stress test; distinguish platform settings, seller records, formulas, estimates, and scenario assumptions in the evidence ledger.

Sensitivity and counterexample: seasonal promotion margin data sources

Change one supported scenario input while preserving all declared held variables. Control 3 names the authority, owner, review frequency, exception code, threshold, expiry, correction trigger, and prior restorable campaign packet.

Retain failed, below-target, and above-capacity fixtures. Apply the control specifically to an evidence-backed campaign stress test; distinguish platform settings, seller records, formulas, estimates, and scenario assumptions in the evidence ledger.

Platform rule boundary: seasonal promotion margin data sources

Separate official discount, combination, shipping, commission, and budget rules from seller-editable assumptions. Control 4 names the authority, owner, review frequency, exception code, threshold, expiry, correction trigger, and prior restorable campaign packet.

Never universalize one platform's mechanics. Apply the control specifically to an evidence-backed campaign stress test; distinguish platform settings, seller records, formulas, estimates, and scenario assumptions in the evidence ledger.

Privacy and access: seasonal promotion margin data sources

Use aggregate inputs, synthetic fixtures, redacted pointers, access controls, retention, and deletion rules. Control 5 names the authority, owner, review frequency, exception code, threshold, expiry, correction trigger, and prior restorable campaign packet.

Exclude raw buyer, order, coupon, click, payment, credential, token, and OAuth data. Apply the control specifically to an evidence-backed campaign stress test; distinguish platform settings, seller records, formulas, estimates, and scenario assumptions in the evidence ledger.

Source promotion mechanics: scenario drill

What an evidence-backed campaign stress test can and cannot prove

It can prove that entered aggregate assumptions follow the declared campaign dates, order grain, promotion mechanics, revenue and cost bases, scenario changes, target, capacity, formula version, and evidence scope.

It cannot predict demand, conversion, product mix, buyer behavior, attribution, incremental sales, inventory availability, labor performance, carrier service, accounting profit, liquidity, tax treatment, or future campaign results.

Block, review, release, and restore the promotion evidence map

Block invalid percentages, negative values, private exposure, missing mechanics, incompatible periods, stale scope, or declared conflicts. Review either scenario below target or above capacity. Ready means both entered cases preserve target within documented capacity.

Release only a reversible public model with synthetic defaults, first-party sources, original diagrams, accessible labels, canonical, Article and Breadcrumb schema, internal links, strict 404 behavior, correction policy, and rollback evidence.
