Written and reviewed by Seller Profit Guard Editorial Team.
Use the same mature retained orders, retained revenue, product mix, zones, package profile, service level, currency, and return window. For each option, add pick-pack, packaging, shipping, storage, software, minimums, receiving, returns, and other documented costs; subtract product and fulfillment cost from retained revenue; then review contribution and practical capacity.
Close the cohort
Use the same mature retained orders, retained revenue, product mix, zones, package profile, service level, currency, and return window. For each option, add pick-pack, packaging, shipping, storage, software, minimums, receiving, returns, and other documented costs; subtract product and fulfillment cost from retained revenue; then review contribution and practical capacity. Keep economic, capacity, evidence, and operational definitions separate before comparison. Checkpoint 1 in the fulfillment formula ledger records currency, product mix, destination zones, package profile, service level, retained-order denominator, return maturity, forecast, source version, owner, reviewer, and accepted formula before interpretation.
For close the cohort, keep retained revenue, product cost, observed seller time or provider charge, packaging, carrier shipping, storage, software, minimums, receiving, returns, other costs, total fulfillment cost, contribution, forecast, capacity, threshold, conflict, backup, stop rule, and restoration separate.
