Reference & Evidence

Source: Author's framework grounded in Helgesen (2000) and Zbaracki, Ritson, Maklan, and Dean (2004). Helgesen's working paper is a Norwegian export setting; Zbaracki et al. is one price-adjustment firm. Neither supplies a universal service-cost allocation rule.

Each line is a claim from the register this journal publishes against, resolved from the register at build time.

  • A The setting is one industry in one country: "Norwegian exporters of klipfish and frozen fish are chosen as a context" Helgesen. (2000) · HLG00-C1
  • A The sample, verbatim: "the sample, consisting of 564 orders related to 176 customer and 36 geographical markets" Helgesen. (2000) · HLG00-C2
  • A The rule is stated as a rule: "Costs are assigned to the level where they are incurred (orders, customers, markets, etc.). All the revenues are related to the order level", and "Then revenues and costs from orders are transferred to the customer level" Helgesen. (2000) · HLG00-C3
  • A The paper says the method changes the answer: descriptive customer profitability can be built with "full costing (the absorp""tion method), (2) variable costing (the contribution margin method) or (3) activity based costing", and "These methods will of course tend to result in different designs of the specified accounts" Helgesen. (2000) · HLG00-C4
  • A "the managerial costs are more than 6 times and customer costs are more than 20 times the menu costs" zbaracki-etal-2004-price-adjustment-costs · ZRLDB04-C1
  • A "in total the price adjustment costs comprise 1 22 of the company s revenue and 20 03 of the company s net margin": one firm, one period zbaracki-etal-2004-price-adjustment-costs · ZRLDB04-C2
  • B A customer P&L boundary should follow the cost object and where the cost is incurred, not the reporting convenience of a revenue dashboard Author framework grounded in Helgesen (2000) · B08-C1
  • B Service costs should be classified by order, customer, market, and business-unit level before a team decides whether to allocate them further Author framework grounded in Helgesen (2000) and Zbaracki et al. (2004) · B08-C2
